(1)Subject to the provisions of this Part, an Assembly Measure may make any provision that could be made by an Act of Parliament.
(2)An Assembly Measure is not law so far as any provision of the Assembly Measure is outside the Assembly’s legislative competence.
(3)A provision of an Assembly Measure is within the Assembly’s legislative competence only if it falls within subsection (4) or (5).
(4)A provision of an Assembly Measure falls within this subsection if—
(a)it relates to one or more of the matters specified in Part 1 of Schedule 5, and
(b)it neither applies otherwise than in relation to Wales nor confers, imposes, modifies or removes (or gives power to confer, impose, modify or remove) functions exercisable otherwise than in relation to Wales.
(5)A provision of an Assembly Measure falls within this subsection if—
(a)it provides for the enforcement of a provision (of that or any other Assembly Measure) which falls within subsection (4) or it is otherwise appropriate for making such a provision effective, or
(b)it is otherwise incidental to, or consequential on, such a provision.
(6)But a provision which falls within subsection (4) or (5) is outside the Assembly’s legislative competence if—
(a)it breaches any of the restrictions in Part 2 of Schedule 5, having regard to any exception in Part 3 of that Schedule from those restrictions,
(b)it extends otherwise than only to England and Wales, or
(c)it is incompatible with the Convention rights or with Community law.
(7)For the purposes of this section the question whether a provision of an Assembly Measure relates to one or more of the matters specified in Part 1 of Schedule 5 is to be determined by reference to the purpose of the provision, having regard (among other things) to its effect in all the circumstances.
