The Irish Free State, which came into existence in 1922, had a status akin to that of dominions such as Australia and Canada, with a written constitution. This constitution was replaced in 1937 with the present one, which proclaimed the complete independence of Ireland (or, in the Irish language, Eire), which by the Republic of Ireland Act 1948 formally declared itself to be a republic. On independence, existing law continued to apply in the Irish Free State, and the 1937 Constitution also provided that existing law should continue in force insofar as it was not inconsistent with the Constitution. As a result it is not uncommon to find that legislation passed by the Westminster Parliament prior to independence applies in Ireland and that rules of law laid down by UK courts prior to independence are applied. Ireland is different from the UK in that its laws can be struck down by the Supreme Court if found to conflict with the Constitution in a similar way to other countries with formal constitutions such as the USA.
