Ireland Act 1949
The Ireland Act 1949 is a law of the British Parliament that should take into account the consequences of the Republic of Ireland Act of the Irish Parliament. This law is still largely in force, but has been changed somewhat by the Northern Ireland Act (1998) .
Provisions
The main provision is that the incorporation of the Republic of Ireland and its withdrawal from the Commonwealth is accepted but that "the Republic of Ireland is not a foreign country". It is also noted that the name Republic of Ireland may replace Éire in the United Kingdom . This part is still legally binding .
The law also stipulated that Northern Ireland would remain part of the UK in order to guarantee the unionist majority there that Northern Ireland could be part of the UK for as long as it wants. This was the first legal guarantee of its kind given to Northern Ireland.
