This Order, which is made under section 2(2) of the European Communities Act 1972 for the purpose of complying with Council Directive 1976/207/EEC(following the judgment of the European Court of Justice in Case 222/84 – Johnston v The Chief Constable of the Royal Ulster Constabulary) disapplies certain provisions of the Sex Discrimination Act 1975 and the Sex Discrimination (Northern Ireland) Order 1976.

Those provisions are disapplied so far as they relate to those Parts of the 1975 Act or the 1976 Order which are concerned with discrimination in the employment field and related areas.
