Peace Treaties, Trade agreements, treaties or agreements relating to international organization, those committing the finances of the State, those modifying provisions which are the preserve of statute law, those relating to the status of persons, and those involving the ceding, exchanging or acquiring of territory, may be ratified or approved only by an Act of Parliament.
They shall not take effect until such ratification or approval has been secured.
If the Constitutional Court, upon referral by the President of the Union, by the President of the Assembly of the Union or by the Heads of the island executives has held that an international undertaking contains a clause contrary to the Constitution, authorization to ratify or approve the international undertaking involved may be given only after amending the Constitution.
Treaties or agreements duly ratified or approved shall, upon publication, prevail over Acts of the Union or the islands, subject, with respect to each agreement or treaty, to its application by the other party. (Art. 10)
