Outcomes
Application for judicial review dismissed.
The court found that the claimant's grounds of challenge were unarguable. The Secretary of State's decision was deemed lawful and rational.
Secretary of State's decision to grant development consent upheld.
The court rejected the argument that the permanent water supply should be considered part of the Sizewell C project for the purposes of environmental assessment. The Secretary of State's approach, considering it a separate, subsequent project with cumulative impacts to be assessed later, was found to be lawful.
