It made sense, therefore, in any examination of the choices open to the Government in the matter of providing how the provisions of the convention could be made applicable in the State, rather than for the State as a consequence of our obligations under international law, to look closely at the sub-constitutional interpretative model in the 1998 Human Rights Act adopted for England and Wales, Scotland and Northern Ireland. Other possible options explored included direct incorporation of the relevant articles of the convention in the Constitution. This would have to be effected by changes in the relevant articles of the Constitution as agreed by the people in a referendum.
