[2004] EWHC 860 (Admin), High Court, judment on 26th April 2004, reported at [2004] IRLR 430..
In particular the unions claimed that the marital status exception in reg 25 was not permitted by the EC Framework Directive.
The High Court rejected the claims mainly on the basis that given a purposive construction the regulations properly implemented the directive. The Court specifically confirmed as a general principle that legislation implementing Directives is not required to copy out the wording of the Directive in full. However the High Court gave leave to appeal to the Court of Appeal.
