The Act Commentary on Sections Part 10: General Section 108 Commencement
272.Section 108 makes detailed provision about commencement. Most provisions are to be brought into force by the Secretary of State in relation to England or the National Assembly for Wales in relation to Wales. Some provisions which relate to England only, or to matters which are not devolved, are to be brought into force by order by the Secretary of State alone. Others come into force two months after Royal Assent. Provisions not mentioned in section 108 come into force on Royal Assent (the provisions in question are all technical in nature).
