Becoming a TD and early social influences Having a family connection to the party, Costello had been a member of Fine Gael since joining college. In 1951, at the age of just 24, he was elected to
Dáil Éireann as a Fine Gael
TD for the
Dublin North-West constituency during
that year's general election. He was the youngest member of the house at the time, earning him the informal title of
Baby of the Dáil. The following years would significantly influence Costello's political views; his exposure to the poor living conditions of his constituents in Dublin North-west radically altered his views on housing. In 1953, Costello married Joan Fitzsimons. With Joan, Costello would go on to have four sons and two daughters. One of these sons was later found to have
autism, and the cause of children with special needs quickly became an area of special concern for Costello, particularly as "his elder brother Wilfrid had been left with a mild mental disability during birth". In the aftermath, a dejected Costello sought to become the party's spokesperson for Finance, but instead was handed the position of spokesperson for health and social welfare. Costello was further frustrated by Cosgrave's limp espousal of the Just Society concept. Although outside the confines of Fine Gael, Costello continued to remain in the political sphere. He would host parties and meetings of Fine Gael and Labour members, where they would discuss possible Fine Gael/Labour coalitions, how to dislodge Cosgrave as leader of Fine Gael and even the possibility of forming a new political party. When the prospects of an actual Fine Gael/Labour coalition became more and more tangible from 1970 onwards, Costello announced he would stand for the Dáil in the next election. He stood in a different constituency from his previous one, moving to
Dublin South-West, but was elected at the
1973 Irish general election. The inclusion of a progressive such as Costello on the Fine Gael ticket helped cement the Fine Gael/Labour coalition. As Attorney General, Costello refused requests by members of the coalition to have their constituents' minor criminal charges squashed, an established practice in Ireland. Costello sought to depoliticise the office of Attorney General and successfully did so in 1975 upon his establishment of the
Director of Public Prosecutions's office. From then on, briefs for criminal cases would be apportioned despite the party relationship. Finding many of his attempts to reform Irish law stifled by a combination of bureaucratic lethargy and defiance from vested interests, Costello founded the Law Reform Commission in 1975. Although the Law Reform Commission lacked resources or political support, in time it was able to produce significant legal reform in Ireland thanks to its institutional status. During his time as Attorney General, Costello proved to be a thorn in the side of the British government. Costello was vocal in his belief that, wherever possible, the Irish state should refuse to extradite
Provisional Irish Republican Army prisoners to the United Kingdom. Costello's stance was born out of his experience in 1973 when he was in charge of Ireland's case with the
European Commission of Human Rights being against the UK for the internment and torture of nationalists in Northern Ireland. Costello had been convinced he needed to establish precedent in international law on the matter, regardless of diplomatic concerns. Engaging the political right and tabloid press in the UK, Costello was able to prove in court that the British state was illegally using
sensory deprivation techniques on prisoners. In 1977, it was decided by the court that the prisoners were treated harmfully before giving the verdict of the UK being cleared of torture. For having created the Office of the Director of Public Prosecutions and the Law Reform Commission, Costello has been called the "most consequential attorney general in the state's history". == Judicial career ==
