The Equal Opportunities Commission successfully brought judicial review proceedings in the High Court, challenging the validity of the Employment Equality (Sex Discrimination) Regulations 2005 which amended the Sex Discrimination Act 1975. The EOC contended that the regulations failed to properly implement certain parts of the EC Equal Treatment Amendment Directive. The High Court ruled that the regulations are incompatible and therefore the government is obliged to make the necessary amendments to the legislation. The government planned to bring the amended regulations into force on 1 October 2007, but implementation has been postponed as further work is required.
