The purpose of section 3 is to give legislative effect to those measures by providing for an exemption from the requirement for an employment permit for the nationals of these states, should they wish to take up employment in the State. The section has regard to the parties of the treaty of accession. The acceptance of the proposed amendment would not only mean including states that are not covered by the treaty of accession, but it would also make reference to instruments that do not yet exist and the provisions of which may be entirely different to those contained in the current accession treaty.
