Detail

The Supreme Court unanimously dismissed both appeals brought before it regarding HS2. All 7 judges agreed with the Court of Appeal and High Court that the Strategic Environmental Assessment (SEA) Directive did not apply to HS2. They also did not consider that changes need to be made to the hybrid Bill process to comply with the Environmental Impact Assessment (EIA) Directive. The Court has decided that in both cases it is not necessary to refer any EU law questions to the Court of Justice of the EU.
