These Regulations codify, to a limited extent and in the particular context of occupational pension schemes, the effects of Article 157 of the Treaty on the Functioning of the European Union (“the right to equal pay”) and of the right to non-discrimination on grounds of sexual orientation as regards employment and occupation established by Council Directive 2000/78/EC establishing a general framework for equal treatment in employment and occupation (OJ L 303, 2.12.2000 p. 16-22) (“the Framework Directive”). The effects to be codified form part of domestic law by virtue of section 4 of the European Union (Withdrawal) Act 2018 (c. 16).
