Powers relating to retained EU law Section 13: Powers to restate: general
Section 13 establishes the general parameters of what a restatement under sections 11 and 12 can do and how it should be conducted.
	Subsection (2) establishes that a restatement can use different words or concepts from those used in the secondary retained EU law that is being restated.
	Subsection (3) sets out that the relevant national authority may make changes which it considers appropriate for one or more of the below purposes -
resolving ambiguities;
removing doubts or anomalies; and
facilitating improvement in the clarity or accessibility of the law.
	Subsection (4) places limitations on the powers, preventing a broader reinstatement of the principle of supremacy. So far as sections 11 and 12 may reproduce the effects of supremacy as part of a restatement, subsection (4) establishes that provisions made by regulations under sections 11 and 12 may include provisions about the relationship between the restated legislation and any other specified relevant enactment, but it may not, however, specify the relationship between the restated legislation and all enactments. Subsection (9) ensures that this ability to set out the relationship between a relevant enactment and a restatement does not overlap with the power in section 7. Where an authority wishes to set out the relationship between RDEUL and a restatement that is not contained in RDEUL, then the power under section 7 will be available to set out the relationship between the RDEUL and the restatement.
	Subsection (5) clarifies that the powers under section 11 or 12 may not be used to codify or reproduce the principle of supremacy of EU law or a retained general principle of EU law.
	Subsection (6) establishes that nothing in subsection (5) prevents regulations under section 11 or 12 from codifying or reproducing for a particular enactment an effect that is equivalent to an effect which is produced by virtue of the principle of supremacy of EU law or retained general principles of EU law, or an effect that would be produced were it not for sections 3 to 5 in this Act. Subsection (6) also outlines that this also applies where codifying and reproducing anything which is or was retained EU law by virtue of section 4 of the European Union (Withdrawal) Act 2018.
	Subsection (7) establishes that the provision that can be made by regulations under this section can be made by making modifications to any enactment. Whilst only secondary REUL or secondary assimilated law may be restated under the respective powers in sections 11 and 12, this subsection will allow the restatement to be made in primary legislation, for example. As set out above, that enables the codification or reproduction of case law or general principles to sit alongside related primary legislation, or for the consolidation of any REUL/assimilated law to be placed in primary legislation if appropriate.
	Subsection (8) clarifies that the restatements under sections 11 and 12 may maintain a particular policy effect by express provision or otherwise.
	Subsection (10) clarifies that references to "retained general principles of EU law" in subsections (5) and (6) have the same meaning as that set out in sections 11 or 12 of this Act.
	Subsection (11) clarifies that in section 13 a reference to "restatement" (a) in relation to section 11, has the same meaning as in that section, and (b) in relation to section 12, has the same meaning as in that section but also includes reproduction. Amongst other things this ensures that "restatement" also includes codification.
