Subsection (1) introduces Schedule 7, which determines the Parliamentary procedure to which subordinate legislation under the Act is to be subject.  See the note on Schedule 7 for further information.
Subsections (2) and (3) deal with the transitional circumstances where, by virtue of Schedule 7, a power to make subordinate legislation is subject to procedure in the Scottish Parliament but the power needs to be exercised before the Scottish Parliament itself is in existence.  For example, the power in section 15 to specify office-holders who are disqualified from membership of the Scottish Parliament is to be subject to Type D procedure (laid in draft and approved by the Scottish Parliament), but a list of office-holders is clearly required for the first elections to the Parliament.  Subsections (2) and (3) provide that such powers may nevertheless be brought into force at any time after the passing of the Scotland Act (although this may be before the Parliament is in existence) and that subordinate legislation under the power may be made subject to a different type of procedure for the period until the principal appointed day (1 July 1999), with this procedure being specified by subordinate legislation under section 129(1).
This power was exercised in making the Scotland Act 1998 (Transitory and Transitional Provisions) (Subordinate Legislation under the Act) Order 1998 (S.I. 1998/3216), which adjusted the procedures for orders under sections 15, 38 and 97 and paragraphs 2 and 7 of Schedule 2.  In the case of orders under section 15, which were mentioned above, the first order was made subject to Type B procedure (laid in draft and approved by both Houses of the UK Parliament).
As from the principal appointed day (1st July 1999), the parliamentary procedure for all orders is as set out in Schedule 7, and the powers in subsections (2) and (3) are effectively spent.
