Transport Action Network v Secretary of State for Transport (A428 Black Cat Road Scheme)

In August 2022, the UK government granted development consent for the A428 Black Cat to Caxton Gibbet road scheme in Cambridgeshire, England. The proposal was for a new dual carriageway. Transport Action Network issued a public law challenge to the decision, including on climate grounds. They claimed the scheme was the third biggest carbon emitting scheme under the government's current roads programme. According to online reports, the High Court refused permission for the claim to proceed to trial. This was initially done 'on the papers', but was reaffirmed following a permission hearing on March 30, 2023. The Court of Appeal then refused the claimant permission to appeal, bringing the challenge to an end.
