Article 55

The King shall accredit ambassadors to foreign States and international organizations. Ambassadors and representatives of international organizations shall be accredited to Him. He shall sign and ratify treaties. However, treaties of peace or union, or those relating to the delimitation of borders, treaties of commerce or those committing the finances of the State or whose application requires legislative measures, as well as treaties relating to the individual or collective rights and freedoms of citizens, may be ratified only after having been previously approved by law. The King may submit any other treaty or convention to Parliament before its ratification. If the Constitutional Court, seized by the King or the Head of Government or the President of the Chamber of Representatives or the President of the Chamber of Councillors or one sixth of the members of the first Chamber or one quarter of the members of the second Chamber, declares that an international commitment contains a provision contrary to the Constitution, its ratification may occur only after the revision of the Constitution.
