Costello’s Constitutional Turn
Archived: 8 October 2026
In 1948, Fianna Fáil lost its Dáil majority after sixteen years, enabling John A. Costello to lead the First Inter-Party Government, supported by Clann na Poblachta, Labour and others. The coalition addressed post-war housing, welfare, health, employment and agricultural trade, while Ireland joined European recovery co-operation and concluded a British trade agreement. Costello’s September Canadian announcement preceded the Republic of Ireland Act, enacted in December. Although effective only in 1949, it repealed the External Relations Act, ended the Crown’s remaining external role and authorised presidential functions. Partition remained unchanged, while An Taisce’s foundation and Olympic return suggested national civic renewal.
