This is Case C-145/04, in which the Kingdom of Spain brought proceedings under Article 227 EC, against the United Kingdom of Great Britain and Northern Ireland. They were accused of having infringed Community law by virtue of the arrangements made for the inhabitants of Gibraltar to vote in the European Parliament elections and in particular by arranging for people who reside in that territory but are not Member State nationals or therefore citizens of the Union, to vote.
Article 227 of the EC Treaty provides that 'A member State which considers that another Member State has failed to fulfil an obligation under this Treaty may bring the matter before the Court of Justice'. Such cases are rare and therefore are worth looking at.
