Electoral (Amendment) Act 1980
The Electoral (Amendment) Act 1980 (No. 17) was a law of Ireland which revised Dáil constituencies. It took effect on the dissolution of the 21st Dáil on 21 May 1981 and a general election for the 22nd Dáil on the revised constituencies took place on 11 June 1981. This Act repealed the Electoral (Amendment) Act 1974, which had defined constituencies since the 1977 general election. It was the first revision of Dáil constituencies to adopt recommendations from an independent Commission. This commission was chaired by Brian Walsh, judge of the Supreme Court, and delivered its report  on 21 April 1980. The constituencies were also in operation for the duration of the 23rd Dáil elected at the February 1982 general election on 18 February 1982 and the 24th Dáil elected at the November 1982 general election on 24 November 1982. It was repealed by the Electoral (Amendment) Act 1983, which created a new schedule of constituencies (making minor changes to boundaries in Dublin only) first used at the 1987 general election for the 25th Dáil held on 17 February 1987.
