The Irish Statute Book in its broadest sense is the total of all laws which are applicable the Republic of Ireland at this time, these include all British, English and Irish laws made over the centuries. All primary and secondary legislation enacted since 1922 have been made available for free access to all via the internet by the Office of the Attorney-General of Ireland.
In 1937 the state proclaimed a new constitution, the Constitution of Ireland, and renamed the state as Ireland (Éire) now generally known as the Republic of Ireland.
All previous law was also carried forward at this time, with it being left at the discression of the Oireachtas to reform these laws.
The President of Ireland must sign all bills into law as passed by the Houses of the Oireachtas, but does have a number of limited powers to decline signing, generally this means referral to the Supreme Court but does include other methods of referal not yet evoked.
From 1922 to 1935 the effective law on nationality in the Irish Free State was based on the common law and the British Nationality and Status of Aliens Act 1914 which remained in force as a pre-1922 statute that had not been repealed.
Because of Ireland's impending departure from the Commonwealth (on 18 April 1949), special provision was made for the retention by certain citizens of the Irish Free State of the status of British subject, without being citizens of any Commonwealth member state.
The IrelandAct 1949 came into force on 18 April 1949, and effectively recognised the withdrawal of the Republic of Ireland from the Commonwealth.
