Chris Packham loses appeal

As noted in previous posts the naturalist and broadcaster Chris Packham has sought to challenge, by way of judicial review, the Government’s decision to proceed with the HS2 project in the light of the Oakervee Review (OR). In Packham v Secretary of State for Transport [2020] EWHC 829 (Admin), the High Court refused him leave to apply for judicial review on the grounds that there was no arguable case. Mr Packham then appealed against that decision to the Court of Appeal which has now also rejected the claim: R (on the Application of Packham) v Secretary of State for Transport [2020] EWCA Civ 1004; [2020] 7 WLUK 494.

Despite the fact that, technically speaking, there has been no judicial review in that the application to bring judicial review was rejected, there has in fact been a form of de facto judicial review in that the Courts ended up considering the points in great detail in order to ascertain whether they were in fact arguable; such is the nature of ‘time-saving’ interloctuary procedures!

The High Court proceedings are dealt with extensively in my post entitled: Packham v Secretary of State for Transport. As is usually the case with any appeal, some of the issues fell away before the hearing. The Court was left to determine the procedural issues of whether the claim was in time and the intensity of the review which should be undertaken before turning to the substantive arguments. These were claims 2 and 3b on whether the OR and decision paid sufficient attention to the environment and climate change respectively.


A preliminary consideration was whether the claim had been brought ‘promptly’ for the purposes of rule 54.5(1) of the Civil Procedure Rules. The Divisional Court ruled that, as the matter pertained to an infrastructure project, the six week time limit imposed by section 118 of the Planning Act 2008 ought to be used as the benchmark for determining promptness. The Court of Appeal rejected the argument that the decision in question ought to be treated as analogous to planning decisions governed by the 2008 Act: ‘Neither the Oakervee Review nor the Government’s decision of 11 February 2020 were made within any statutory framework, whether for the planning of major infrastructure or otherwise.’ (at para [45]). This is a logical conclusion in that a central component of the defendant’s argument was that this was not a planning decision; the planning part of the process had already been concluded culminating in an Act of Parliament.

However, this small victory would have been of limited consolation to the claimant in that the Court rejected all the other arguments in fairly emphatic terms.

Intensity of Review

The Court of Appeal endorsed the finding of the Divisional Court to the effect that this was essentially a political decision falling outside the formal planning process. As such it would only be subject to a ‘light touch’ Wednesbury approach whereby the report and the decision could only be impugned on the grounds of irrationality. Moreover, it was the type of matter where the decision maker would be afforded a ‘broad margin of discretion.’ The Court then briefly itemized the key reasons for this finding (at para [52]):-

  1. The decision was taken at the very highest level of Government;
  2. The Cabinet was fully aware that phase 1 of the scheme had already been authorized by the 2017 Act;
  3. There had been no physical changes between the Royal Assent and the Cabinet’s decision capable of undermining the environmental assessment undertaken pursuant to that Act;
  4. It was a case where the Cabinet had to balance a multitude of competing political, economic, social and environmental considerations.
  5. As a result of point 4 there could be no ‘right’ decision.
  6. The Oakervee Review report had obvious limitations.

All of which underscored ‘the essentially political quality of the decision.’ (para [53]).

The fact that the Court of Appeal emphasized the political nature of the decision and the ‘broad margin of discretion’ meant that the claimant faced an uphill task in establishing that the decision was fundamentally flawed in terms of how the environmental arguments had been addressed. Where a decision is political and the decision maker has a broad margin of discretion it is very difficult to show that the decision was so flawed that it was irrational.

Failure to consider environmental effects

The first substantive argument (ground 2 of the original claim) was that the decision to proceed was flawed in that it failed to properly consider the environmental effects of the scheme. There were two aspects to the claim. The first aspect was that the OR purported to set out a full and comprehensive analysis of the environmental effects when it clearly did not do so. The second aspect was that the cabinet (as decision maker) must be taken to have based its decision solely on the review believing it to contain a full and comprehensive review of the environmental effects. There could be no assumption that it was fully aware of the wider context of the project and the detailed environmental assessments which had been undertaken pursuant to the 2017 Act under which the first phase of the project had been authorized. Given that the OR did not in fact contain a full and comprehensive review of the environmental effects of the project and given that there could be no assumption that ministers must have been aware of the assessments which had already been done,  any decision to proceed based upon the findings of the OR must have been flawed.

The weight attached to the Oakervee Review

Taking the second aspect first, the Court of Appeal regarded the argument that ministers had to be regarded as being entirely reliant on the OR and unaware of the background of the project as entirely artificial. By the time that the OR was set up in August 2019 the ‘factual context’ of the project ‘was a matter of record.’ Thus, ‘the idea that the Cabinet, when forming the decision, lacked that basic knowledge of the project is, in our view, wholly unrealistic.’ (at para [64]). In his submissions (which can be viewed on the Court of Appeal YouTube channel) Mr Wolfe, for the claimant, repeatedly and forcefully made the point that the Government had consistently failed to adduce any documentary evidence that, when making the decision, the Cabinet had before it papers other than the OR. Thus, there could be no assumption that it had followed guidance in the Cabinet Office Manual which states that ‘[papers] and presentations for Cabinet … should include any information that is needed for ministers to make an informed decision’ (paragraph 4.30).

In any event the Court of Appeal appeared to regard this argument as somewhat of an irrelevance. Whether or not the Cabinet, on the day of the decision, had a specific briefing document before it on the background of the scheme and a detailed account of all the environmental assessments which had already been undertaken, ‘it is simply not credible’, the Court contended,

‘that in the circumstances in which the review was commissioned and the decision made, the Secretary of State, or any other minister, was ignorant of the legislative and procedural history of HS2, including the fact that the statutory approval process involved a lawful and comprehensive assessment of environmental impacts.’ (at para [64]).

The claimant also adduced a number of public law cases which imposed strict limits on the ability to make assumptions that certain procedural steps had been taken or to impute knowledge possessed by one person involved in the decision to another. The Court of Appeal held that all such authorities  were clearly distinguishable in that they all concerned adherence to strict procedural requirements in legislation governing the decision. In the case at hand the procedural requirements and duties pertaining to the central planning decision had already been fulfilled and the requisite powers granted:-

The decision now being taken was not a decision on the planning merits, it was a decision on whether or not to proceed with a project whose planning merits had already been considered in a statutory process, and its first phase approved in an Act of Parliament (at para [65]).

The Court of Appeal also firmly rejected any suggestion that the Secretary of State and the Cabinet as a whole had laboured under any misapprehension about the purpose, scope and limitations of the OR. They knew full well that the OR fell outwith the formal planning procedures:-

the review was not part of the legislative process for the approval of the project. It did not engage either domestic or EU legislation on environmental impact assessment. The Government was under no obligation to set it up. To do so was not necessary to discharge any duty arising under any Act of Parliament or at common law, or to comply with any policy promulgated by this or any previous administration. There was no statutory or policy basis for the terms of reference. Though a number of organisations and individuals took the opportunity to make representations to the panel, there was no duty here to undertake public consultation. (at para [66]).

Moreover, it was clear that the Government never had any intention of basing its decision solely on the OR. In a statement to the House of Commons on 3 September 2019 the Secretary of State for Transport, Mr Grant Schapps, stated that ‘its recommendations would inform our decisions on the next steps’ (the Court of Appeal’s emphasis); thus it was clear that the OR would not ‘dictate’ the Government’s decision (see para [67].

The scope and purpose of the Oakervee Review

The Court was equally dismissive of the other limb of the argument on ground 2, namely, that the OR itself misrepresented its scope and purpose and claimed a degree of comprehensiveness and detail which it could not possibly have achieved given the limitations of time and resources.

The first point that the Court made was that the OR had to be viewed in the light of the time constraints placed upon it and what could realistically be achieved in the time frame. A phrase used a few times in the submissions in the Court of Appeal hearing (which did not make it into the judgment) was that it was a ‘quick and dirty’ review (see submissions on YouTube, above). Another point made by Mr Mould for the defendant (which was also not covered in the judgment itself) was that the report was largely motivated by a need to justify the mounting costs of the project rather than a desire to revisit all the environmental arguments.

The panel comprising the OR had not been asked ‘to undertake a comprehensive assessment’. Apart from the impossibility of achieving this within the time-frame it was entirely unnecessary in that an assessment had already been concluded pursuant to the 2017 Act and a similar process was already in train as regards phases 2a and 2b. The terms of reference of the review made it clear that, ‘the review was not, and was never suggested to be, a self-contained evaluation of HS2 as a project. It was much more circumscribed than that.’ (para [70]). The Court then listed the following points as being of crucial importance (at paras [72-74]):

  • The terms of reference of the OR could not be criticized as ‘being inadequate, inconsistent or unclear.’
  • There was no suggestion that the panel misconstrued the terms of reference and the report was faithful to them: ‘There is nothing to indicate that, in doing so, it failed to consider with care any relevant content in the representations submitted to it.’
  • Leaving aside the issue of developments in the field of carbon emissions (dealt with below) there were no significant changes in circumstances which could have called into question the soundness of the assessments already completed in respect of phase 1.

Furthermore, at no point did the report attempt to, or purport to, conduct its own comprehensive review of the impact of the project on ancient woodlands etc. All it did was to mention some of the mitigation measures which had been adopted and to draw the conclusion that such measures must always be kept under review. Thus, the Court rejected the claimant’s submission that the report was presented as a full and comprehensive assessment of the environmental effects (para [75]).

All of the above led the Court of Appeal to draw two major conclusions (summarized at para [82]):-

  1. There could be no suggestion that the Government had misled itself as to the nature and purpose of the report and treated it as a full, thorough and comprehensive assessment of the environmental effects: ‘it would have been obvious to ministers that the environmental impacts of HS2, and the proposed mitigation, had been, and would be, formally assessed in accordance with the law. The review report did not have to spell that out.’
  2. There was no legal requirement for the OR to contain a ‘thoroughgoing, or any, assessment of environmental effects’ when deciding ‘whether and how’ HS2 should proceed given that those procedures had already been concluded in respect of phase 1 and were still in train as regards the other phases.

Climate change

The other substantive ground (ground 3b of the original claim) focused upon whether the OR and subsequent decision paid sufficient heed to the exigencies of the Paris Agreement as adopted by amendment of the Climate Change Act 2008. This requires the achievement of net zero emissions of greenhouse gases by 2050. Although the line would be carbon neutral in the long term, emissions caused by construction (e.g. from construction machinery and the manufacture of steel and concrete etc) could impede the attainment of the 2050 target. Thus, ‘it [the OR] did not explain, nor did the Government take into account, how the impacts of HS2 on climate change would sit with the requirements of the Paris Agreement, and the domestic legal framework designed to carry it into effect.’ (at para [91]) It was argued that it was not enough to acknowledge the issue, there had to be some thorough legal analysis of the implications.

The Court of Appeal commenced by firmly rejecting this argument before expanding upon its reasons for doing so:-

In our view it is impossible to infer from the report any failure by the panel to have regard to the Government’s relevant statutory and policy commitments on climate change. And the Government did not demonstrably commit any such error in making its decision. On this point too, we agree with the Divisional Court. There is nothing to show that the Government either ignored or misunderstood the legal implications of proceeding with HS2 for its obligations relating to climate change, including those arising from the Paris Agreement and under the provisions of the Climate Change Act . (para [92])

The Court then made two points in support of this assertion (at paras [93-94]). Firstly, it reiterated a point made many times in one form or another throughout the judgment. The OR fell entirely outside any of the legislation or planning mechanisms pertaining to HS2. There was no legislative requirement to undertake such a review in the first place or to consider climate change issues outside the formal planning process. One could summarize this argument by simply saying that the OR and associated decision were not planning decisions at all. It was part of a political process for deciding whether to use powers which had already been gained under formal planning procedures.

The second point was that, given that the review fell entirely outside these planning mechanisms, the Government had an entirely free hand in terms of setting the terms of reference of the review. It was up to the Government to set out what issues it wanted advice on when deciding whether to continue with the project. The Government was therefore entitled to set terms of reference relating to climate change which were limited in scope; that did not render the terms of reference defective:-

[I]t is worth recalling here that in the terms of reference the only mention of any consideration relating to climate change is in connection with “environmental benefits” – namely, “in particular for carbon reduction in line with net zero commitments”. This is not a shortcoming in the terms of reference, but merely a fact. The Government was under no obligation, statutory or otherwise, to extend them by requiring a wider or deeper consideration of the consequences for climate change of constructing and operating HS2, or by embracing, for example, the “legal implications” of increases in carbon emissions caused by the construction of the project. (para [94]).

As regards the content of the OR on this issue the Court held that the review engaged fully with the climate change issues and the implications of the Paris Agreement and the 2050 commitment. It drew attention to the fact that construction was likely to push up carbon emissions in the run-up to 2050 but noted that this had to be weighed against the long term potential of the scheme to reduce emissions. Moreover, it noted the need to constantly look for further improvements that could be made in the short to medium term. Thus, ‘…the panel did not neglect the period before 2050. On the contrary, it took care to consider what would be happening in the course of that period. It concentrated on emissions likely to be generated in the construction of HS2, which would be going on during those years.’ (para [96]). All in all, the OR more than fulfilled the objectives which had been set for it in the terms of reference.

Finally, the Court dispensed with the argument that the Plan B Earth case on the Heathrow third runway was authority for the proposition that the Government was duty bound to consider climate change issues in a far more intensive manner than the OR. As may be recalled from my previous posts, in the Heathrow third runway litigation the claimants successfully argued that the Airports National Policy Statement (ANPS) was defective in that it failed to address the implications of the Paris Agreement. The Court of Appeal held that there had been a clear breach of sections 5(8) and 10(3) of the Planning Act 2008 in that there had been a conscious decision not to consider the Paris Agreement. However, in the case at hand the Court of Appeal rejected the applicability of the Plan B Earth case for three reasons (at para [103]):-

  1. As the Court had already said ad nauseam throughout the rest of the judgment, the OR and associated decision fell entirely outside the planning process and any legislative requirements: ‘The Government was at liberty to select the issues on which it wished to be advised by the Oakervee review, against the background of HS2’s evolution as a project, including the statutory approval process. The Heathrow case fell squarely within the requirements of the Planning Act 2008 and the need to adhere to specific requirements on climate change.
  2.  The advice given in the report ‘dealt amply’ with the issues and was ‘legally impeccable.’
  3. When the Government gave its decision in 2020 it would have been ‘fully aware of the United Kingdom’s commitments under the Paris Agreement.’

Thus, as with the general environmental arguments,  the claimant’s specific arguments on climate change were firmly, if not emphatically, rejected.


The decision will  no doubt earn its place in the textbooks in that it has raised some novel and interesting issues.

The novelty of the case resides in the fact that, never before has a Government gone to all the trouble of obtaining an Act of Parliament to authorize a project only to risk re-opening the matter by publishing a subsequent report which it did not have to commission and making a decision thereon which it did not have to make! Nevertheless, despite the novelty of the issue, the Court of Appeal applied a fairly straightforward public law analysis regarding the distinction between essentially political and procedural decisions. Here, we had a political process belated added onto a formal planning process. Had there been no OR it would never have occurred to anyone to challenge a project which had been authorized by Act of Parliament. Mr Packham thought that the OR and associated decision presented him with an opportunity to mount an indirect challenge against the legitimacy of the entire project on environmental grounds.

In the event the Court of Appeal found that the OR asked a distinct question, namely, ‘whether and how’ to proceed with a project which had already been authorized. This was not the same thing as deciding whether to authorize or grant permission in respect of a project in the first place. The former is a political decision and the latter is a planning decision. As such there was a great deal of flexibility in terms of setting the terms of reference of the review and the weight attached to its findings. Indeed, at one point the Court of Appeal stated that the Government had had an entirely free hand in setting the terms of reference and need not have included environmental issues at all!

As I have repeatedly said in my previous posts on this litigation, the case also raises issue of Parliamentary sovereignty.  Mr Packham’s purpose in bringing the claim was clearly to put a spanner in the works of the entire project by using the OR as a vehicle for questioning the basis upon which the 2017 Act was passed. The Court of Appeal did not tackle this matter head on but there is the briefest of oblique references to the issue at para [52]:-

Secondly, at the date of the decision the Cabinet can be taken to have been aware, at least, of the existence of the 2017 Act and the fact that in the course of the passage of the Phase One Bill through Parliament a detailed assessment of environmental impacts had already been carried out. That assessment had not precluded the coming into force of the statute. It remained lawful and valid at the time of the Oakervee review, and at the time of the decision. So did the statutory approval process itself. And that will remain so regardless of the outcome of these proceedings. (emphasis added).

This represents a strong indication on the part of the Court of Appeal to the effect that it would have  had no power to stand in the way of an Act of Parliament, even if the OR and associated decision had been found lacking. It seems that the most Mr Packham could have hoped for was a declaration that the process had been defective; although this would most certainly have caused political embarrassment. However, one must also bear in mind the decision of the Court of Appeal in R (on the Application of Edwards) v the Environment Agency [2006] EWCA Civ 877, [2007] JPL 82, [2007] Env LR 126, [2007] Env LR 9, where the Court questioned the utility of making such a declaration where to do so would have no effect on the statutory power or authorization in question: see, in particular [para 130]. Interestingly, counsel for Mr Packham, Mr David Wolfe QC, also represented the claimant in Edwards; one can only speculate as to whether he was trying to get the Court to reappraise its stance in the case at hand!

Apologies for being very slow off the mark on this but there have been many distractions over the past few months as you can imagine.

On 15 April 2020 Hs2 Ltd issued the notice to proceed which enables the contractors to commence construction in earnest. No time was wasted during the Covid 19 lock-down and the first recognizable piece of civil engineering has begun to emerge with the outlines of the southern portals of the Chilterns Tunnel. These mark the entry points for the huge tunnel boring machines (TBMs) which will dig the tunnels.

Just a few days beforehand the High Court ruled against Chris Packham in his judicial review which sought to challenge the decision to proceed with the project in the light of the Oakervee Review (OR): Packham v Secretary of State for Transport [2020] EWHC 829 (Admin). In addition he had sought an interim injunction to prevent HS2 from continuing with clearance work affecting 6 ancient woodlands. My last entry on this issue which was posted just before the Covid 19 crisis really took hold on these shores contained much speculation about what the key arguments might be. I can now report on the precise nature of those arguments and how the court, comprising Coulson LJ and Holgate J, responded. However, the challenge very nearly failed to get any sort of airing at all in that there was an argument about whether it was out of time.

Was the challenge out of time?

Rule 54.5 of the Civil Procedure Rules provides that claims must be filed ‘promptly’ and no later that 3 months after the grounds for filing the claim arose. As regards nationally significant infrastructure projects s 118 Planning Act 2008 stipulates that actions must be commenced with 6 weeks of the relevant planning decision. Although the OR was not a planning decision as such, given that the matter pertains to a nationally significant infrastructure project, the Court was of the view that 6 weeks was a useful bench mark against to which to measure the issue of promptness in such circumstances. In this case the publication of the OR report and the decision to proceed with the project both occurred on 11 February 2020. The pre-action protocol letter was sent on 28 February and judicial review proceedings were not commenced until 27 March, some 6 weeks and 3 days since the OR publication and ministerial decision.

The Court rejected the argument that the delay was due to critical information which had only come to light some time after the 11 February. The substantive arguments all focused upon the OR report itself and no information which may or may not have come to light subsequently could be regarded as critical to the case (see para [44]).

An additional reason which suggested that the claimants had not been sufficiently prompt was that, due to the timing of the proceedings, the contractors were rapidly running towards the end of the window of opportunity during which the clearance work could be done  whilst minimizing the impact on birds and bats (see para [42]).

Nevertheless, given that the issue had only come to light at the hearing and had not been fully argued the Court gave the benefit of the doubt to the claimant and allowed him to air his arguments (see para [45]). It is these arguments to which we shall now turn.

The scope of any possible challenge

In my previous post on this issue I emphasized the fact that the Oakervee Review (OR) had to be viewed in the context of the overall decision making process and could not be regarded as having ‘hit the reset button’ on that process thus requiring the promoters to begin from scratch. Indeed, this would effectively require one to overlook the existence of an Act of Parliament authorizing phase 1 of the scheme: the High Speed Rail (London – West Midlands) Act 2017. It is possible to see echoes of this view in parts of the judgment (not that I can ever know whether anyone involved read my blogs!).

The immense scale of the environmental assessment which had had to be undertaken and the arduous nature of the Parliamentary proceedings which the promoters were required to negotiate in order to obtain the necessary Act of Parliament could not simply be ignored. It was unrealistic to assume that the OR was intended to set all that to one side and start afresh with a blank sheet of paper:-

The OR involved 10 Panellists, not the innumerable people involved in the 5 years of the Bill stages leading to the 2017 Act. It had to produce a result in weeks, not years. Its stated purpose was to inform the decision as to whether HS2 should continue, not to consider the project from scratch. Essentially, the OR had to look and see what had changed since 2017 and to consider whether those changes meant that the project should be halted. (para [48])

The problem with the OR was that it fell entirely outside the formal planning process and the promoters had never been under any obligation to undertake such a review. It was part of a purely political decision as to whether the Government should persevere with the project (which had already been authorized by Act of Parliament) or completely reevaluate it:

There was no statutory basis for the decision to launch the OR in August 2019. The decision to commission the OR was not a prerequisite for lawful exercise of powers under 2017 Act for Phase 1 (or indeed for continuing to promote the Bill for Phase 2). There was no statutory or policy basis for the terms of reference. (para [49])

This raised two questions; to what extent is such a decision susceptible to judicial review and, in making such a decision, must the minister confine himself to information produced solely for the purpose of informing that decision closing his mind to all other matters pertaining to the planning and delivery of the project?

As regards the first point the Court held that, in undertaking the review, the Minister was exercising a ‘common law power’  to make  a ‘macro political decision’ on a nationally significant infrastructure project for which he was accountable to Parliament (see para [54]). Given that there was no legislative requirement to undertake such a review and given the essentially political nature of the decision, ‘a judicial review of that decision would involve only a low intensity of review’ (para [55]). Thus, on this point the court concluded that:-

… when dealing with matters depending essentially upon political judgment, matters of national economic policy and the like, the court will only intervene on grounds of bad faith, improper motive and manifest absurdity (para [55]).

In other words, the decision could only be impugned is on conventional, ‘light touch’ Wednesbury grounds.

The Court gave short shrift to the second issue, namely, the argument that the decision to proceed had to be judged solely by reference to the quality of the information and analysis in the OR taken in isolation from all other aspects of the decision making process:

In a situation where a Minister is considering a review of a complex project which did not involve a call for evidence, it seems to us to be a nonsense to suggest that the Minister could only be assumed to know about the review, and not the Parliamentary process by which environmental issues have been and will be addressed and Phase 1 has been approved. The Review cannot be divorced from that process in the way suggested by Mr Wolfe QC; on the contrary, as paragraph 2.3 of the Report itself made clear, the OR did not start from a blank sheet of paper, because of all the proceedings which had resulted in the 2017 Act. (para [56])

The Court then proceeded to consider the substantive points raised by the claimant with a view to determining whether any of them could provide grounds for impugning the decision according to a ‘light touch’ Wednesbury analysis.

Specific criticisms of the Oakervee Review

The process of the OR

One argument was that the OR had departed from its terms of reference with the result that the minister could not be confident that the final report fulfilled the objectives which had been set. This mainly centered  on the testimony of Lord Berkeley, the former co-chair of the OR who left the role and published his own report having developed sharp disagreements with Oakervee and the other panelists. Most of the criticisms focused on the fact that the latter stages of preparing the report had been dominated by Oakervee and other panelists had been less involved and there were comparatively few meetings involving all panelists. The Court rejected the argument that such matters constituted significant departures from the terms of reference of the review. They were largely expedient measures dictated by the time constraints and limited resources of the review which was never intended to entirely reopen the decision making process from scratch:

In particular, in our view, he never made any allowance at all for the fact that the OR had very limited resources, was not able to call for evidence, and was required to work extremely quickly in order that any delays to the OR and thus the HS2 project were kept to a minimum. Indeed, most of Lord Berkeley’s criticisms of the process (from his comments on the terms of reference to the contents of his witness statement) arose from the inevitable speed and other limitations against which the OR had to be conducted. It appears that Lord Berkeley never came to terms with the severe constraints on the OR. (para [63])

Thus, it seems that the Court was of the view that Lord Berkeley had unrealistic expectations in terms of the scope of the review, its purpose, and what it could hope to accomplish in the limited time-frame.

Local environmental concerns

The claimant argued that the OR was entirely inadequate in terms of its consideration of local environmental concerns such as specific wildlife habitats and wild animal populations. The Court firmly rejected these arguments on the basis that they raised no new information and were, ‘simply a re-run of the points made 4, 5, 6 years ago during the debates about HS2.’ Thus, it was ‘entirely illegitimate to seek to reopen these matters in the guise of a challenge to the OR and the decision of 11 February.’ (see para [73]. Once again, this aspect of the judgment makes it clear that the Court was not prepared to consider the OR in isolation or regard as having re-opened the entire decision making process from scratch. Such concerns has been extensively examined in the environmental assessment and the 2017 Act had been passed in the light of all this information.

Climate Change

The Court also rejected the argument that the OR failed to adequately consider the climate change implications of the project. One aspect of the challenge focused on emissions from construction and operation of the line. It was held that the OR  ‘fairly summarised the overall assessment regarding the construction and operation of HS2.’ The relevant part of the report (para [5.27]) provided a range of figures which accommodated construction emissions at both the lower and higher ends of the spectrum. The report drew the reasonable conclusion that, whilst it might be difficult to secure significant further reductions in the construction of phase 1 (which is already getting underway) HS2 should focus on how it can reduce construction emissions in respect of the next phases. Thus:

Read fairly and properly, the OR Report did take into account the passage quoted by the Claimant from the paper by the Interested Party, in particular the expectation that construction carbon emissions would be greater than 8m tonnes. The contrary is not arguable. Nor is it arguable that the Report was misleading or that there was any need for the Report to go into further detail. The Defendants have not failed to take into account a relevant factor to which they were legally obliged to have regard. Ground 3a is unarguable. (para [97])

As anticipated in my earlier post, the claimant also made a great deal of the recent Heathrow third runway litigation. However, as I noted, the case generated rather more excitement than it deserved in that there had been a complete failure to consider the Paris Agreement. This constituted a clear breach of a very specific duty in section 5(8) of the Planning Act 2008 to ‘take account of’ government policy on climate change in the preparation of national policy statements (and ‘take account of’ sets the bar quite low in any case). Unlike the Heathrow third runway case, which was about the extent to which the decision maker ought to have factored in something which had yet to be formally adopted, the OR had been undertaken after the Paris Agreement had been enshrined in domestic law (see previous post). Hence, the report was drafted in a way which fully acknowledged the nature of the commitments made under the Paris Agreement.

Moreover, once again, one has to note that the OR has to be viewed in the wider context of the decision making process and the extensive studies carried out into climate change implication as part of the environmental assessment. As noted above, the Court held that it was a ‘nonsense’ to divorce the OR from the other aspects of the decision making process; again, this is explored more fully on my previous post on this issue.

Legitimate expectation

The next argument put by the claimant was that, by its terms of reference, the OR had created a legitimate expectation that there would be a full and detail reappraisal of the environmental arguments including climate change. The Court noted that this appeared to repackage the arguments already put to the effect that the OR had failed to carry out a sufficiently detailed and thorough review of the environmental arguments. The Courts responded in similar vein, namely, that the OR had never been designed to rerun all the arguments from scratch and, given the time-frame and resources accorded to it, it would be entirely unrealistic to expect the OR to address such matters in the level of detail desired by the claimant. Once again, the point was made that the OR could not be viewed in isolation from the overall process and the very detail assessments which had been made in respect of phase 1 and were still ongoing in relation to phases 2a and 2b:

For the reasons we have given above, the Claimant’s argument proceeds on a misunderstanding of the nature of the OR and its terms of reference. Furthermore, the challenge completely overlooks the environmental assessment already carried out in the Parliamentary proceedings on Phase 1 and which remain to be carried out for Phases 2a and b. There was no undertaking to carry out a “full assessment”, or any detailed assessment, of the environmental impacts in the review which was to be carried out over a 2-month period in the Autumn of 2019. Much detailed work remains to be carried out. (para [105]).

Interim injunction

The present proceedings stemmed from an application for an interim injunction to halt certain works pending a full judicial review of the issues and to seek permission to bring judicial review proceedings. The claimant had originally sought to obtain an injunction first thereby ‘pausing’ the works until the issues had been litigated. However, it became clear that the injunction could not be considered in isolation from the application to bring JR; both raised similar arguments relating to the prospects for success of the claim which inevitably leads to an analysis of the merits of the arguments.

The Court applied the usual tests set out in cases such as R (Medical Justice) v Secretary of State for the Home Department [2010] EWHC 1425 (Admin). One of the key tests is whether the claimant has shown ‘a real prospect of success’ on a least one of the claims. Given that the Court had dismissed every one of the claims as unarguable the outcome of this determination was never in doubt and the application was rejected. However, the Court ruled that, even if the claimants had demonstrated that one or more of the grounds was arguable, on the usual ‘balance of convenience’ test, it is likely that it would have declined to grant the injunction. Aside from the huge financial costs of the resultant delays (exacerbated by the afore-mentioned missing of a vital window for doing clearance work before nesting season) there was the not insignificant matter that such an injunction would conflict with powers conferred by Parliament.

[I]t is necessary to bear in mind that that harm has already been assessed through the Parliamentary process and it has been judged that the project should nevertheless proceed in the national interest. These considerations underscore why it has been so important for the court to grapple with the fundamental question of whether the grounds of challenge are legally arguable at this stage. (para [125])


The fact that the High Court was prepared to subject the ministerial decision and the Oakervee Review to even the lightest form of judicial review (‘light touch Wednesbury’) is surprising. The elephant in the room in this case which the Court did not confront was that the challenge was clearly an attempt to derail (pun intended) the entire project via the back door. Mr Packham was seeking a remedy which would have prevented the promoters and their contractors from exercising powers conferred by an Act of Parliament. In effect, this constitutes a challenge to the legality of that Act of Parliament, something which no court has the power to do.

Of course, it has to be conceded that a finding against the minister in this case would not necessarily have brought the Court into direct conflict with the legislature in this way. The Court might then have simply made a declaration that that specific part of the process was flawed. This might have served the interests of the claimant by embarrassing the Government and bringing increased political pressure to bear on it; but it would not have called a halt to the project. However, Mr Packham clearly wanted more than that in that he sought an interim injunction preventing the clearance of certain woodlands.

As noted above, the Court did not immediately dismiss the possibility of gaining an injunction in such circumstances out of hand. The Court stated that, had it been necessary to consider whether to grant injunctive relief, on the ‘balance of convenience test’ it is likely that it would have declined the application and allowed the works to continue. The Court then acknowledged the fact that such a remedy might conflict with the Act authorizing the works:

In any event, the clearance works were long ago authorised by Parliament and there is a strong public interest in ensuring that, in a democracy, activities sanctioned by Parliament are not stopped by individuals merely because they do not personally agree with them. (para [133])

This is not as emphatic as one might have expected. The fact that the Court even contemplated the possibility that the balance of convenience test could be applied suggests it was of the opinion that it is theoretically possible to obstruct the operation of an Act of Parliament by way of injunctive relief – this cannot be right. There was no suggestion that anyone involved in the scheme had exceeded their statutory powers thereby bringing ultra vires into play, the claim was designed to frustrate the operation of the Act itself. Moreover, even if one looks beyond the justiciability issue and considers the substance of the report itself, it is clear that the OR has to be viewed in the overall context of the decision making process. Irrespective of whether one looks at it subjectively or objectively, the OR cannot be construed as superseding the entire decision making process. It is a nonsense to assert that the process did not, at the very least, satisfy the ‘take account of’ environmental factors test. Indeed, as I argued in my previous post, the process has gone way beyond that minimal approach.

The case is now scheduled to be heard by the Court of Appeal on 8 July and I shall try and be quicker off the mark in terms of reporting on those proceedings.

Fresh HS2 Legal Challenge

Dave Bushell

I had hoped to leave HS2 alone for a while and catch up on other issues such as the world of franchising. However, further to my last entry on HS2 Mr Packham through his solicitors Leigh, Day & Co has launched the first stage of his judicial review of the decision of the Government to press ahead with the project in the light of the Oakervee Review. As a result I feel that I have little alternative other than to offer my initial observations.

The arguments

We now have a much clearer view of the arguments and it seems that the Oakervee Review is indeed at the heart of the challenge. It is contended that the Oakervee Review was flawed in that it failed to pay sufficient attention to the climate change implications of the project. For example, it is argued that issues such as emissions from construction machinery were largely overlooked as was the possibility of increased air travel arising from better regional airport connectivity (although, as regards the latter point one cannot help but point out that the Heathrow link was ditched!) Moreover, the challenge has been given added emphasis by the successful challenge in the Court of Appeal against the third runway at Heathrow again on climate change grounds.

It’s all about procedure

The main point to note is that this is all about the planning process and compliance with procedural requirements pertaining to the fulfilment of environmental requirements. As such it is slightly odd that the main focus appears to be on a policy document such as the Oakervee review. Leaving aside the argument set out in my previous post to the effect that it is doubtful whether such a document could be construed as resetting the entire decision making process, it is worth noting the Supreme Court decision in R (on the application of Buckinghamshire County Council and others) v Secretary of State for Transport [2014] UKSC 3, [2014] 1 WLR 324 (more on which later). Here it was held that a policy document which proclaimed the Government’s desire to build HS2 (Department for Transport, High Speed Rail: Investing in Britain’s Future – Decisions and Next Steps Cm 8247 (2012)) was not the planning decision which triggered the need for compliance with procedures pertaining to environmental protection (the need for a strategic environmental assessment in this case). Under the hybrid Bill procedure Parliament is the decision maker and it is the preparation of the Bill which triggers environmental assessment: see, for example, Lord Carnwath at [38]. Policy documents, advisory opinions, review panels, statements of intent and so forth in no way bind the hands of the decision maker.  Thus, the main focus needs to be on the adequacy of those planning procedures which do in fact govern the decision making process.

Heathrow 3rd Runway Case

Before turning to the HS2 case itself it is necessary to say something about the Court of Appeal decision on the third runway at Heathrow which has been credited as giving added impetus to the HS2 challenge: R (on the application of Friends of the Earth) v Secretary of State for Transport and others [2020] EWCA Civ 213. The decision is not quite as ground-breaking as has been made out and focuses on narrow procedural requirements. Heathrow expansion is being dealt with under the Planning Act 2008 rather than hybrid Bill procedure. The Act relates to large scale infrastructure projects and a crucial stage is the designation of a ‘national policy statement’ (NPS) by the Secretary of State which sets government policy and provides a firm framework for the next stages of the process: see Airports National Policy StatementSection 5(8) of the Act specifically requires the NPS to ‘take account of’ government policy on climate change. The NPS appeared to have taken account of the Climate Change Act 2008 (CCA 08) but, at the material time, the CCA 08 had not been amended to reflect the commitment which the Government had agreed to under the Paris agreement to hold ‘the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels.’ In fact, there had been an express decision not to incorporate the exigencies of the Paris agreement in the NPS because it had yet to be incorporated into domestic law. This is where NPS fell short in that the Court of Appeal held that the  expression ‘government policy’ clearly goes beyond legislative measures and includes other commitments and decisions. The Court (perhaps sensing that people were likely to get carried away by the significance of the decision) bent over backwards to emphasise the point that it was doing nothing novel in requiring the decision maker to adhere to clearly set out procedural requirements in the planning legislation. As the Court said at [230] “…requiring the Crown to comply with what has been enacted by Parliament (in this case the obligations in section 5(8) of the Planning Act) is an entirely conventional exercise in public law.” Moreover, the Court was at pains to point out that, if the decision maker had in fact taken the Paris Agreement into account, the scope for judicial scrutiny of the manner in which he had done so would have been limited: “We repeat that the duty in section 5(8) does not even require the executive to conform to its own policy commitments, simply to take them into account and explain how it has done so.” (at [231]). Overall, it seems that there was a very specific procedural defect which is unlikely to reoccur thanks to this judgment and the fact that the CCA 08 has now been amended in any case so as to reflect the Paris Agreement. To this end the Climate Change Act 2008 (2050 Target Amendment) Order 2019 SI 2019/1056 substituted the existing target (to reduce the carbon account to 80% below the 1990 baseline) with a commitment to achieve a 100% reduction: see Explanatory Memorandum.

HS2 and Environmental Assessment

All in all the Heathrow case was a highly traditional judicial review decision with the Court seeing its role as one of ensuring that the decision maker adheres to the letter of the rules that have been set in terms of reaching the decision but largely steering clear of the substance of the decision. Thus, in turning to the HS2 project our focus must also be on compliance with the relevant procedures rather than the substance of the decision. As noted above, the HS2 project is subject to the hybrid Bill procedure. It is divided into 3 phases (notwithstanding the attempt to merge phase 1 with phase 2a) and the current state of legislation reflects these 3 phases. Thus, it is logical to look at each one in turn.

Phase 1

Legislation has already been enacted in respect of phase 1  of the scheme from London to  Birmingham and the West Midlands: the High Speed Rail (London – West Midlands) Act 2017. Standing orders for private and hybrid bills had to be adjusted to take account of the need for environmental assessment. At the material time the relevant legislation was set out in Directive 2011/92/EU on Environmental Impact Assessment and House of Commons Standing Order (SO) 27A.  An environmental statement was prepared in pursuance of these requirements and was submitted to Parliament with the Bill and its associated documents in November 2013. It must be conceded that climate change did not feature heavily in the 2011 Environmental Impact Assessment Regulations SI 2011/1824 which were applicable at the time. In fact, there was just one fleeting reference to ‘climatic factors’ in the list of factors which an environmental statement should cover. Furthermore, under environmental assessment the duty is to ‘consider’ environmental factors which is arguably even weaker than ‘take account of.’ Nevertheless, the environmental statement which was attached to the phase 1 Bill fully engaged with the issue and contained a detailed assessment of climate change factors: see HS2 Phase 1 environmental statement volume 5: climate change. Moreover, the documents show that the study was conducted in the light of the Climate Change Act 2008 and the pre-Paris commitment to reduce carbon emissions to at least 80% below the 1990 baseline. Finally, in the aforementioned judicial review proceedings of 2014, the Supreme Court held that the hybrid Bill procedure was fully compatible with the requirements of environmental assessment: R (on the application of Friends of the Earth) v Secretary of State for Transport and others [2020] EWCA Civ 213.

Mr Packham’s solicitors have pointed out that matters have moved on since this environmental statement was prepared in that the UK government signed up to the Paris agreement and has indeed now amended the CCA08 accordingly. However, this suggests that the CCA08 amendment has some form of retroactive effect which is capable of reopening planning decisions which have already been made in accordance with the law that applied at the time. In the absence of very clear and express words to that effect this is very doubtful to say the least. It is also interesting to note that in the Heathrow third runway case the Court of Appeal said at one point that there was no incompatibility between the pre and post Paris targets in that the 80% reduction target was expressed as a minimum (see [225]); in which case the targets might not be so different. In any event, under the UK constitution it is simply not possible for a court to strike down an Act of Parliament.

Phase 2a

That brings us to phase 2a of the scheme which extends the line beyond the West Midlands to Crewe. As noted in my previous post on the issue the relevant legislation was introduced in the House of Commons in July 2017: the High Speed Rail (West Midlands – Crewe) Bill 2017-19 to 2019-21. The Bill progressed as far as the appointment of s select committee in the House of Lords to hear petitions before the dissolution of Parliament ahead of the December 2019 General Election. Both House of Parliament have now passed revival motions which means that the Bill does not have to be re-introduced and can be taken forward from where matters were left off. The environmental statement associated with this Bill was prepared in accordance with the more recent Environmental Impact Assessment Regulations 2017 SI 2017/571 which makes far more extensive references to climate change than its predecessor. As one would expect, the phase 2a environmental statement contains a detailed analysis of climate change issues and, notwithstanding the fact that the statement was prepared ahead of the amendment of the CCA 08, the Paris Agreement and the Government’s commitments there-under are expressly referred to: see, for example High Speed Rail (West Midlands – Crewe) Environmental Statement: Volume 3: Route Wide Effects where it is referred to throughout section 4 on climate change.

Phase 2b

As regards phase 2b concerning the completion of the line to Manchester and the other arm of the ‘Y’ shape to Leeds the project is under review and has been bundled up with the Northern Power House Rail Project so as to integrate HS2 with improving connectivity between Northern Cities. Hence planning is at a much earlier stage and the original proposals may be subject to extensive change. However, this means that there can be no doubt whatsoever that environmental assessment, which is currently at a ‘working draft’ stage (and clearly subject to major revisions if there are changes to route and project specifications etc) will be conducted according to the latest climate change policies. Indeed, as one would expect, the current working draft is already replete with references to the Paris Agreement: See High Speed Rail (Crewe to Manchester and West Midlands to Leeds) Working Draft Environmental Statement – section 4 on climate change.


Phrases such as ‘take account of’ and ‘consider’ environmental effects such as climate change arguably set the bar relatively low in terms of what the decision maker must do although they certainly go beyond paying mere ‘lip service’ to them. Provided that there has been some form of proper assessment which has been filtered into the decision making process the Court of Appeal has made it clear in the Heathrow case that the Court will be extremely chary about intervening in the actual substance of the decision:

As we have said, we are required – and only required – to determine whether the Divisional Court was wrong to conclude that the ANPS was produced lawfully. Our task therefore – and our decision – does not touch the substance of the policy embodied in the ANPS. In particular, it does not venture into the merits of expanding Heathrow by adding a third runway, or of any alternative project, or of doing nothing at all to increase the United Kingdom’s aviation capacity. Those matters are the Government’s responsibility and the Government’s alone. (at [282].

There can be no doubt that the environmental statements prepared in respect of HS2 go far beyond minimal requirements. With a subject as complex and controversial as climate change it will always be possible to find experts who may disagree with the technical data or conclusions drawn in an environmental study; but this is not sufficient to impugn the decision.

In conclusion, there is simply no mileage at all in the argument that the HS2 project has not taken sufficient account of climate change issues and has ignored the requirements of the Paris agreement. To take the Oakervee review document in isolation and ignore the extensive assessments which have been carried out (or are still underway) in respect of all three phases of the project is nonsensical in the extreme.



HS2 gets the green light – again!

When the High Speed Rail (London – West Midlands) Act received the Royal Assent in 2017 one might have been forgiven for thinking that the legal and political shenanigans were over and work would begin in earnest. However, arguments over ever increasing costs meant that the ‘notice to proceed’ (which authorises the contractors to move in with their earth movers and commence the major civil engineering phase) has been continually delayed. This has left contractors fiddling around trying to find every scrap of preparatory work they can do within their current authorisations such as site clearances, building compounds, construction of access roads and diversion of utilities. The change of Conservative Party leadership brought about by infighting over Brexit then cast doubt over whether there was still a political consensus in favour of delivering the project. Despite his well known enthusiasm for major infrastructure projects the Prime Minister, Boris Johnson, was not prepared to endorse the scheme the moment he took office. Instead, he announced that an  independent panel, under the chairmanship of Douglas Oakervee, would be appointed to advise on whether there was still a case for proceeding with the project. The report (which was leaked before the Government formally wished to release it) found in favour of proceeding with both phases of the scheme despite the escalating costs: see ‘Oakervee Review.’ This week , of course, there was a huge media splash when the Prime Minister enthusiastically endorsed the scheme in Parliament with a characteristic flourish: HC Deb 11 February 2020, vol 671, cols 712-714.

At present only phase 1 of the scheme from London to Birmingham has been authorised by Act of Parliament. Phase 2A from Birmingham to Crewe, the first leg of the extension to Manchester, is to be brought forward and effectively treated as part of the first phase. A Bill covering phase 2A was introduced to the House of Commons on 17 July 2017  (the High Speed Rail (West Midlands – Crewe Bill) 2017-19. It had got as far as the appointment of a Select Committee in the House of Lords to hear petitions before the dissolution of Parliament ahead of the December 2019 General Election. Given the Prime Minister’s desire to bring forward stage 2A and merge it with stage 1 there can be no doubt that a revival motion can be expected any day now in order to set the legislative wheels turning again.

The phase 1 Act from London to Birmingham withstood two major legal challenges, both of which were dealt with on these pages. In R (on the application of HS2 Action Alliance Limited) (Appellant) v The Secretary of State for Transport and another (Respondents) [2014] UKSC 3 the Supreme Court held, inter alia, that the hybrid Bill procedure was compatible with the requirements of environmental assessment: see my post entitled ‘HS2 win in Supreme Court‘. The exigencies of Environmental Assessment came to the fore again in R ( on the application of HS2 Action Alliance, London Borough of Hillingdon) v Secretary of State for Transport [2014] EWCA Civ 1578: see my post entitled ‘HS2, safeguarding directions and strategic environmental assessment.’ Here it was held that safeguarding directions, which restrict development along the line of the proposed route, do not trigger the need for an environmental assessment.

Despite the fact that phase 1 of the scheme has already been authorised by way of an Act of Parliament and that the procedures for complying with environmental assessment have been endorsed by the Supreme Court, the Daily Mail reported that the television presenter and naturalist, Chris Packham, had been in consultations with Leigh Day & Co regarding a possible legal challenge to the Government’s decision to continue with the project in the light of the Oakervee Review: and this is indeed borne out by an article on Leigh Day & Co’s website. The Oakervee review is criticised as not constituting a thorough analysis of the environmental arguments. We have to wait and see what precise arguments they come up with but it would certainly constitute a bold challenge.

If (and I emphasise ‘if’) any challenge focused on the Oakervee Review it would attach huge weight to the report and regard it as hitting the reset button on the entire decision making process. The intention of the Government in commissioning the review appears to have been more about checking that it still wanted to adhere to its original decision rather than starting the entire process again from scratch as though it was operating in virgin territory; as the report notes at [2.3], ‘it is important to note that any examination of the project does not start from a blank sheet of paper.’ Is a decision as to (in the words of the report) ‘whether and how to proceed‘ (emphasis added) with an existing decision the same thing as making that decision in the first place? If I double check that I want to keep the jumper I have just bought before I lose the receipt (because I am concerned that I may have spent too much money on it!), am I required to take the jumper back to the shop in any event and start the entire jumper buying decision making process again including weighing up the pros and cons of different colours?  Indeed such an approach could set a precedent whereby it is effectively impossible to double check or review major decisions without going back to square 1 and starting all over again; this would lead to paralysis in the delivery of major projects and might actually dissuade decision makers from displaying any hesitation or conducting prudent last minute reviews and adjustments. Moreover, it is difficult to see how the existence of an Act of Parliament, enacted according to procedures which were endorsed by the Supreme Court, can be airbrushed out of the equation.

All the Queen’s Horses: HS2 and Statutory Authority

On a dark December evening in 1827 a sporting gentleman, who chronicled his fox-hunting adventures under the name of Nimrod (Charles James Apperley), was riding on horseback along the Yarm turnpike. Out of the darkness emerged a terrifying apparition which he later described as a ‘moving hell’, a clanking, hissing iron monster exulting ‘blazing fires of blue and yellow hues’. This turned out to be a locomotive steam engine grinding its way along the Stockton and Darlington Railway. Nimrod’s horse was terrified and it took all his horsemanship to maintain control. He wondered at the fact that such a nuisance could be tolerated so close to a turnpike road: See Nimrod’s Hunting Tours – Interspersed with Characteristic Sayings and Doings of Sporting Men (London: Pittman, 1835).

John Dobbin’s famous painting of the opening of the Stockton and Darlington Railway in 1825.

Nimrod was not alone, since the railway opened two years earlier spooked horses on the turnpike had been a common occurrence. Carriages and carts were overturned and riders on horseback were thrown or bolted off with. Soon after Nimrod’s experience on the Yarm Turnpike the directors and enginemen of the Stockton and Darlington Railway were indicted in Public Nuisance. The litigation resulted in the authority of R v Pease (1832) 4 B & Ad 30, 110 ER 366. which established a very important legal principle which relieved the defendant’s of liability. The Stockton and Darlington Railway was authorised by an Act of Parliament and this set the template for the multitude of schemes that followed. The court held that the railway company could not be liable for harms which were the necessary consequence of exercising their statutory powers. It so happens that Francis Mewburn, the solicitor to the promoters of the Stockton and Darlington, had had the good sense to insert a clause into a revised Bill which expressly authorised the use of steam locomotion. This followed a famous meeting between Edward Pease and George Stevenson in which the latter had persuaded the Quaker business man to use steam power rather than horses. The existence of the section enabled the court to find that the spooking of horses on the turnpike was an unfortunate but natural consequence of using the statutory power to operate steam locomotives. The defence went on to play a crucial role in the famous ‘railway sparks’ cases where it effectively afforded the railway companies an immunity in respect of a large proportion of the extensive fire damage caused by sparks from passing steam locomotives.

The second Stockton and Darlington Act which allowed for modifications to the route and the use of steam locomotion.

The first phase of HS2 between London Euston and Birmingham is set to open around the bicentenary of the opening of the Stockton and Darlington Railway.  In 2011 the Times reported that Her Majesty the Queen was alleged to have expressed concern at the potential impact of high speed trains whizzing past at speeds of up to 250mph on horses kept at Stoneleigh. Such concerns were also expressed by a number of equestrians who petitioned against the HS2 Bill at the select committee stage. This brings us neatly full circle; there may be a world of difference between the slow, clanking iron monsters on the Stockton and Darlington and the streamlined, gleaming state of the art electric trains which will operate on HS2. But horses are still timid animals likely to be spooked by something new and invasive in their environment. Another constant feature is that the Act of Parliament is still the instrument of choice for authorising major rail projects; although now the hybrid Bill procedure is used as opposed to the private Bill procedure. Thus, the High Speed Rail (London West – Midlands) Act 2017 must inevitably establish a statutory authority defence in respect of many of the harms arising from the construction and operation of the line.

This is the backdrop to a new article published by Mark Laurence Wilde (who may have something to do with this blog) in Legal Studies. In the article Wilde considers to what extent the defence of statutory authority might shelter the operator from liability in respect of nuisances caused by the operation of High Speed trains. Whilst high speed trains are unlikely to set fire to crops and farm buildings, as their much slower steam powered ancestors were prone to do, they have the potential to cause noise, vibration and, indeed, spooked horses. Wilde focuses on a sometimes overlooked aspect of the statutory defence, namely, the ‘inevitably of harm’ criterion. In short the defence only operates in respect of harms which could not have been avoided. The HS2 project has undergone a vast amount of planning and design and an environmental impact assessment running to 50,000 pages. Thus, there is unlikely to have been a systematic failure to anticipate harms and mitigate them or at least offer compensation where they cannot be avoided. However, Wilde argues that it is still possible that the impact on certain individuals may have been overlooked. For example, not all affected parties had the wherewithal to petition against the Bill and not all who did so would have gained satisfaction. Moreover, certain individuals who may suffer nuisances arising from the operation of the line may fall outside the parameters of the HS2 compensation schemes. Wilde asks whether such individuals could call upon the common law to come to their aid. Litigants would have to show that the harm was not inevitable – on the face of it this sounds like a very difficult criterion to satisfy given the amount of planning and design that has gone into HS2. Nevertheless, it may yet be open to the owner of a riding stable to argue, for example, that additional screening measures ought to have been adopted at a specific location due to the effect of sudden train movements and noise on horses. In fact, such a dispute has already arisen in respect of a much smaller scale project involving a scaling up of passenger services and increases in trains speeds as part of the upgrade of a conventional line: see noise, horses and the Evergreen 3 project.

Wilde concludes that affording the common law the space to intervene in such matters allows it to perform its traditional function of filling the gaps left by legislative procedures and ‘fine-tuning’ the planners’ decisions on the ground. However, this would require the courts to adopt a bold approach to the issue of whether a harm was inevitable. Recent case law developments suggest that they might be more prone to intervene where they perceive that an individual has been left uncompensated by the planning system.
