The Public Service Pensions Act 2013 (c. 25) (“PSPA 2013”) makes provision, and confers powers to make further provision (in the form of “scheme regulations” as defined in section 1 of PSPA 2013), about the establishment of public service pension schemes. The Civil Service (Other Crown Servants) Pension Scheme Regulations 2016 (S.I. 2016/326) (“the 2016 Regulations”) establishes a scheme by analogy to the Public Service (Civil Servants and Others) Pensions Regulations 2014 (S.I. 2014/1964) (“the 2014 Regulations”) with some modifications. The 2014 Regulations provided for transitional protection for certain cohorts of members of predecessor schemes, and this transitional protection was mirrored in the by-analogy scheme established by the 2016 Regulations. The transitional protection was subsequently found to unlawfully discriminate between pension scheme members on the basis of age.
