RATIFICATION OF A TREATY OR A CONVENTION:
This is the stage where the treaty or convention can be invoked.
The ratification expresses the commitment of the State to be a party, thus compelling the latter to implement the provisions of the legal instrument. The ratification is often done by the representatives of the people, the Parliament and it is preceded by a review to ensure that it is in line with the Constitution. This procedure enables the State to raise concerns, where necessary.
« The ratification or accession is an indication that the State has accepted to be legally bound by the provisions of the Convention. Though accession and ratification produce the same effect, the procedures are different. In the case of ratification, the State, first of all, signs the treaty, and then ratifies it. The procedure for accession is carried out once and for all - it is not preceded by any signing.
The official ratification or accession procedures vary according to the national legislation of the State. Before ratifying it or acceding to it, a country generally reviews the treaty to ensure that the legislation is in line with its provisions in order to determine the measures it must take to effectively facilitate its implementation. »
