UK judicial review reform for major projects explained

Ministers have opened a consultation on whether the court process for challenging big planning decisions should be tightened, with the stated aim of stopping weak cases from delaying homes, energy schemes and transport projects. The proposal was announced on 16 July 2026 by the Ministry of Justice and the Ministry of Housing, Communities and Local Government, and it sits inside the Government’s wider push to speed up building. (gov.uk) The first thing to know is that nothing changes overnight. This is a six-week consultation, applying to England and Wales, and it closes at 11.59pm on 27 August 2026. In other words, ministers are asking whether the rules used for the biggest nationally significant projects should also apply to other major developments. (gov.uk)

Judicial review sounds technical, but the basic idea is simple. It is the court’s way of checking whether a public body acted lawfully when it made a decision. Judges are not there to ask whether they personally like a railway line, a solar farm or a housing scheme; they ask whether the law was followed, whether the right process was used and whether the decision-maker stayed within their powers. (judiciary.uk) That safeguard matters because planning decisions can reshape places for decades. Under the current system, a planning challenge normally has to be brought to the High Court within six weeks, and the specialist Planning Court decides at the permission stage whether the case is reasonably arguable. If the court later finds the decision unlawful, it can quash it. (assets.publishing.service.gov.uk)

**What ministers want to change in plain English:** for most planning cases outside the Nationally Significant Infrastructure Projects, or NSIP, system, claimants can currently get up to three tries to clear the permission hurdle. There is usually a paper decision first, then an oral renewal hearing if permission is refused, and then a possible application for permission to appeal. The consultation asks whether the biggest non-NSIP cases should move closer to the newer NSIP model instead. (assets.publishing.service.gov.uk) That newer model is stricter for claims the court sees as hopeless. For NSIPs, reforms in the Planning and Infrastructure Act 2025 mean cases now go straight to an oral permission hearing, and claims judged totally without merit at that stage have no onward appeal. The consultation itself says the paper stage can sometimes filter out weak claims cheaply, so ministers are not proposing this for every planning dispute. (assets.publishing.service.gov.uk)

The consultation is not only about cutting repeat attempts. It also asks whether certain cases should be formally treated as Significant Planning Court Claims, which is court jargon for cases with big economic effects, important points of law or strong public interest. That label brings specialist handling and target timetables, and ministers also want views on whether judges should be encouraged to hold case management conferences once permission is granted so that evidence, deadlines and the real points in dispute are sorted earlier. (assets.publishing.service.gov.uk) There is also a push for tighter court timetables. According to the consultation paper, NSIP cases now have or are due to have shorter deadlines in the High Court and clear targets in the Court of Appeal, including four weeks for permission-to-appeal decisions and four months for substantive appeals. Some of this can be done through court rules, but extending the no-appeal rule for totally without merit cases beyond NSIPs would need primary legislation. (assets.publishing.service.gov.uk)

Scope matters here. The Government is not consulting on every planning row in the country. The paper focuses on big decisions under the Town and Country Planning Act 1990 and the Transport and Works Act 1992, which can cover large housing schemes, transport orders and major energy developments outside the standard NSIP route. (gov.uk) The examples in the consultation are a clue to what ministers have in mind. They point to onshore wind projects over 50MW and under 100MW, electricity network projects and large battery storage over 100MW as 'strategically important developments', and they say there may also be a case for significant housing developments, giving schemes of more than 150 homes as an example. That is why this story is really about much more than legal jargon: it is about which kinds of building get faster treatment in the courts. (assets.publishing.service.gov.uk)

This proposal builds on changes already made for NSIPs. The Government says the Planning and Infrastructure Act 2025 and related court rule changes were designed to make judicial review quicker and more predictable, and its June policy paper says the full package could make the legal process for major infrastructure up to six months faster. The same paper cites the Stonestreet Green solar case, where the new rule was used in April 2026 to dispatch a claim the court treated as meritless. (gov.uk) It also sits alongside wider planning reforms. On 2 July 2026, the Government said mandatory pre-application consultation requirements for NSIPs would be scrapped later in July 2026, which it says could cut up to 12 months from the planning process and save industry £1 billion this Parliament. The judicial review consultation is one piece of that broader attempt to make planning decisions move faster. (gov.uk)

The politics are not hard to spot. Ministers say they want 150 major infrastructure decisions by the end of this Parliament, and the 16 July 2026 press release says 42 such decisions have already been made so far. In housing, official statistics published on 19 June 2026 estimate that 392,400 net additional homes were delivered in England between 9 July 2024 and 14 June 2026, which the Government presents as more than a quarter of its 1.5 million homes target. (gov.uk) When you put those figures next to the legal proposals, the Government’s argument becomes clearer: delay is being framed as a growth problem, not just a courtroom problem. Our reading of the consultation is that the loud press-release line about 'baseless legal claims' points to a narrower legal question underneath it: how far ministers can speed up challenges to big projects without making lawful scrutiny harder to use. (gov.uk)

For readers trying to work out what this means, there are three practical points to watch. First, this is a consultation, not a final law. Second, judicial review is staying in place as a safeguard; the Government says it wants to protect access to justice and the rule of law even while limiting delays from weak claims. Third, the biggest battle may end up being about scope: which projects count as nationally important, and whether major housing should be pulled into the faster track. (gov.uk) That is why this matters beyond planners and barristers. If you care about affordable homes, rail links, clean energy or the right of communities to challenge unlawful decisions, this consultation sits right where those questions meet. The real test will be whether reform can sort weak cases faster without treating every objection as an obstacle. (gov.uk)
