These Regulations amend the statutory provisions that require equal treatment of men and women in respect of occupational pension schemes. The amendments made by the Regulations reflect requirements of European Community law (specifically Article 141 of the Treaty of Rome on equal pay), as applied in a number of cases before the European Court of Justice and the domestic courts. Part 2 of the Regulations applies to occupational pension schemes generally. Parts 3 and 4 of the Regulations introduce new provisions applying only to armed forces occupational pension schemes.
