H.V. Evatt, Australia and Ireland’s departure from the Commonwealth: a reassessment

Abstract

On 7 September 1948 the newly appointed Taoiseach, John A. Costello, the leader of a coalition government in which his party Fine Gael was the senior partner, announced in Ottawa that he intended to repeal Eire’s External Relations Act, and thus sever its final tenuous link with the crown. The External Relations Act ‘empowered the Executive Council of the Irish Free State to authorise the use of the king’s signature on the letters of credence to be presented to heads of foreign states by Irish diplomatic representatives’. Eamon de Valera, Costello’s predecessor, had introduced the External Relations Act in 1936, and had regarded it as a device that might help to end partition. The measure magnified Ireland’s constitutional ambiguity, but with its repeal the twenty-six counties would assuredly become a republic outside the Commonwealth.
