The 1947 revision was repealed by the Electoral (Amendment) Act 1961, which created a new schedule of constituencies first used at the 1961 general election for the 17th Dáil.
The government of Éamon de Valera introduced the Act, which increased the size of the Dáil from 138 to 147 and increased the number of three-seat constituencies from fifteen to twenty-two.
The result was described by the journalist and historian Tim Pat Coogan as "a blatant attempt at gerrymander which no Six County Unionist could have bettered".

The Constitutional Convention's 2013 recommendation to increase proportionality by having larger constituencies was rejected by the Fine Gael–Labour government on the grounds that "the three, four or five seat Dáil constituency arrangement has served the State well since 1948".
