187.Part 4 contains procedural provisions for making Orders in Council under this Schedule. Such Orders will be subject to the affirmative resolution procedure and may amend United Kingdom legislation. These provisions are necessary to provide a mechanism to amend existing legislation, in order that the procedures for consular marriage, provision of certificates of no impediment and armed forces overseas marriages can be modernised. Should the Orders in Council make provision which would otherwise be within the legislative competence of the Scottish Parliament, then Scottish Ministers must be consulted before the Order in Council is made.
