Part 1: The Oil and Gas Authority (OGA) Review Section 16: Review of OGA and guidance from Secretary of State
Section 16 requires the Secretary of State to carry out reviews of the OGA’s performance. Subsection (4) sets out matters which must be considered as part of a review.
	A review must be undertaken for each review period. The first review period will begin with the day on which section 1 comes into force and will end a maximum of three years after that time, unless the Secretary of State specifies an earlier date. Subsequent review periods will begin immediately after the preceding review period and will end a maximum of three years after that time.
	Subsections (5), (6) and (7) set out the process which should be followed by the Secretary of State and the OGA following a review.
	The functions to be considered as part of a review exclude functions which the OGA is authorised to exercise by virtue of an order under section 69 of the Deregulation and Contracting Out Act 1994 or an agreement with the Welsh Ministers under section 7.
