This section confers power upon Her Majesty or a Minister of the Crown, by subordinate legislation, to make provision enabling or otherwise facilitating the transfer of a function to the Scottish Ministers (or its sharing with the Scottish Ministers or its other adaptation).  Such subordinate legislation may, in particular, provide that certain functions can be exercised separately in or as regards Scotland or within devolved competence.
The section also provides that the Secretary of State’s powers of intervention for international obligations under Section 58 apply to the Scottish share of an international obligation expressed in quantitative terms and not to the international obligation itself.
