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 Armed Forces Pensions Regulations 2014 (S.I. 2014/2336) (“the 2015 Regulations”) are the scheme regulations establishing the successor pension scheme (“the reformed scheme”) to six pre-2015 legacy pension schemes for members of the armed forces with effect from 1st April 2015. The Armed Forces (Transitional Provisions) Pensions Regulations 2015 (S.I. 2015/568) amended the relevant legacy pension schemes and provided for transitional protection for certain cohorts of legacy scheme members. Transitional protection of this sort was subsequently found to unlawfully discriminate between legacy scheme members on the basis of age.
