This important case is all about “standing” before the EU courts, namely the ability to complain about some EU act that affects you. Lack of standing means that even if a measure was wrong and unlawful, you cannot get your foot in the door of the court. Domestic rules are quite relaxed, though proposals by Government to make it more difficult to sue Government and other public authorities are currently being consulted upon. But you cannot say that an EU law is unlawful without going to Luxembourg.
The EU Courts have always been very restrictive about the circumstances in which an individual can do so. A brief blip (C-50/00 UPA) a few years ago by a UK Advocate-General suggesting that things be done differently was squashed by the Court. And since then it has been one-way traffic in the EU Courts, brushing off criticism from NGOs and indeed the Aarhus Convention Compliance Committee in 2011 (see here). For a good summary of the EU case law up to 2011, see the ACCC at -
Recent Treaty amendments in Lisbon have, it will be seen, made little difference to the result.
