It appears that Ireland was the first country to ratify the European Convention on Human Rights, while it may be the last to incorporate it in domestic law. The reason for that is the 1937 Constitution, which has been extensively interpreted by the courts, especially with regard to human rights. Some argue that it is more expansive and comprehensive than many conventions, including the European Convention on Human Rights.
I can only assume that because this country has what may be called a Bill of Rights, it was not seen as urgent for this jurisdiction to incorporate the convention. The Deputy is aware that it was open to any individual to bring his or her case to Strasbourg.
