# Dublin North-West (Dáil constituency)

Dublin North-West is a parliamentary constituency in Dublin City represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas. The constituency elects three deputies (Teachtaí Dála, commonly known as TDs) on the system of proportional representation by means of the single transferable vote (PR-STV).

## History and boundaries

The first constituency of this name was created by the Government of Ireland Act 1920 as a 4-seat constituency for the Southern Ireland House of Commons and a 1-seat constituency for the United Kingdom House of Commons at Westminster, combining the former Westminster constituencies of Dublin Clontarf, Dublin St James's and Dublin St Michan's. At the 1921 election for the Southern Ireland House of Commons, the seats were won uncontested by Sinn Féin, who treated it as part of the election to the Second Dáil. It was never used as a Westminster constituency; under s. 1(4) of the Irish Free State (Agreement) Act 1922, no writ was to be issued "for a constituency in Ireland other than a constituency in Northern Ireland". Therefore, no vote was held in Dublin North-West at the 1922 United Kingdom general election on 15 November 1922, shortly before the Irish Free State left the United Kingdom on 6 December 1922.
Under the Electoral Act 1923, which took effect at the 1923 general election, the area was divided between the constituencies of Dublin North and Dublin South.
A second constituency with this name was created by the Electoral (Revision of Constituencies) Act 1935, dividing the old Dublin North constituency into Dublin North-West and Dublin North-East, and first used at the 1937 general election. It was abolished in 1977, under the Electoral (Amendment) Act 1974, with most of the constituency going to the new constituency of Dublin Finglas with a smaller but significant portion going to a new Dublin Cabra constituency.
A third constituency with this name was created in the north-western area of the city by the Electoral (Amendment) Act 1980 and first used at the 1981 general election.
The constituency is overwhelmingly urban; it encompasses Ballymun, Finglas and parts of Glasnevin (Ballygall) and the area of Whitehall to the west of Swords Road in the local government area of Dublin City.
The Electoral (Amendment) Act 2023 defines the constituency as:
       Ballygall A, Ballygall B, Ballygall C, Ballygall D, Ballymun A, Ballymun B, Ballymun C, Ballymun D, Ballymun E, Ballymun F, Beaumont A, Beaumont B, Beaumont F, Finglas North A, Finglas North B, Finglas North C, Finglas South A, Finglas South B, Finglas South C, Finglas South D, Kilmore A, Whitehall A, Whitehall B, Whitehall C, Whitehall D."

### 1952 by-election

Following the death of Independent TD A. P. Byrne, a by-election was held on 12 November 1952. The seat was won by Independent candidate Thomas Byrne, brother of the deceased TD.
The surplus votes of the elected candidate were distributed after being declared elected because there was a possibility another candidate could have reached the threshold of a third of a quota which would have meant their election deposit was returned to them.
