Section 28 or Clause 28 was a legislative designation for a series of laws across Britain that prohibited the "promotion of homosexuality" by local authorities. Introduced by Margaret Thatcher's Conservative government, it was in effect from 1988 to 2000 in Scotland and from 1988 to 2003 in England and Wales. It caused many organisations such as lesbian, gay, bisexual and transgender student support groups to close, limit their activities or self-censor.The law is named after Section 28 of the Local Government Act 1988, which added Section 2A to the Local Government Act 1986. Enacted on 24 May 1988, the amendment stated that a local authority "shall not intentionally promote homosexuality or publish material with the intention of promoting homosexuality" or "promote the teaching in any maintained school of the acceptability of homosexuality as a pretended family relationship". It was repealed on 21 June 2000 in Scotland by the Ethical Standards in Public Life etc. (Scotland) Act 2000, one of the first pieces of legislation enacted by the new Scottish Parliament, and on 18 November 2003 in England and Wales by section 122 of the Local Government Act 2003.
