Walton v. The Scottish Ministers, Supreme Court, 17 October 2012 read judgment
The outcome of this challenge to a road scheme near Aberdeen turned on abstruse points about environmental assessment – but the speeches from the Justices go right to the heart of two big questions in public law.
1. When can someone challenge an unlawful act – when do they have “standing” to do so?
2. If an unlawfulness is established, when can the courts exercise their discretion not to quash the unlawful act, particularly where the unlawfulness arises under EU law?
In the course of the standing issue Lord Hope talks about ospreys – hence my title, but a bit more context first. And we shall also see the views of the Court that standing and discretion are linked questions.
