Sizewell - Court Case

A campaign group opposing the Sizewell C nuclear power station is due to

challenge the government in the High Court over concerns about flooding and
sea level rise. Together Against Sizewell C (TASC) will appear in court
today (Tuesday, the 9th December), when a judge will decide whether the
group can proceed to a full judicial review against the Secretary of State
for Energy Security and Net Zero, Ed Miliband. The legal challenge focuses
on two additional sea defences that Sizewell C Ltd has committed to
installing but were not included in the original planning application for
the project. Chris Wilson, from Together Against Sizewell C, said the
hearing is a “permission hearing where the judge will decide whether we
can go to a full judicial review”. He said the group discovered at the
end of 2024 that Sizewell C Ltd had committed to the Office for Nuclear
Regulation to install additional coastal defences to prevent flooding in
extreme sea-level rise scenarios. “What we subsequently found out was
that these additional sea defences had been known about by EDF, who put in
the planning application for Sizewell C,” he said.

Not the decision we all hoped for!

We are extremely disappointed to advise you of today’s decision by the judge to refuse permission for a judicial review in relation to Sizewell C’s secret additional sea defences.

In TASC’s view, it is immoral to proceed with Sizewell C in the knowledge that the project, as approved in the development consent order, is not resilient to an extreme sea level rise scenario. This will result in future generations having to pick up the pieces from ill-thought-out decisions made today.

Future generations need the government to move forward with sustainable development, not questionable climate change solutions, such as Sizewell C, which come with hidden risks that have been denied public scrutiny, assessment and full consideration of alternatives.

TASC is really grateful to all of our supporters, without whom we would not have been able to take this action. We will now be discussing our options with our legal team and will keep you updated.
THANK YOU
