High Court Imposes Limits on GreenGEN Access Before Judicial Review

17th March 2026

Following last week’s interim relief hearing at Cardiff High Court, the Court has placed important restrictions on GreenGEN’s survey access pending the full Judicial Review hearing.

This means GreenGEN has not been given free rein to enter land.

Instead, the judge allowed only limited access for certain time-critical ecological surveys, and only on a restricted basis. Those limits apply only in the period before the full Judicial Review is heard.

This is an important outcome.

It means the Court accepted that GreenGEN’s access should be constrained, and that any survey activity before the main hearing must take place within a much narrower and more controlled framework.

The main Judicial Review hearing is currently listed for 21 and 22 April 2026, although that timetable could still change.

What this means in practice

GreenGEN’s access is not unrestricted.

Any access before the full hearing is limited to a narrow category of time-sensitive ecological work.

The wider legal challenge continues.

The Court’s interim decision does not determine the final outcome of the Judicial Review, but it does mean GreenGEN’s position has been restricted in the meantime.

What happens next

We now expect further developments in relation to survey notices and the procedures GreenGEN says it will rely on.

As matters progress, we will continue to share general updates on what is happening and what the Court’s decisions mean.

This remains a live and important case, and we are continuing to work hard to ensure that GreenGEN’s conduct is properly scrutinised before the Court.
