Part III of the Social Security Pensions Act 1975 contains provisions for contracting-out from full contributions and benefits under that Act. The Contracted-out Employment (Police) Regulations 1977 relate to the operation and administration of Part III in the case of persons subject to the Police Pensions Regulations in force under the Police Pensions Act 1976, other than persons entitled thereunder only to injury benefit or employed otherwise than as mentioned in Regulation 3 of those Regulations (i.e. employed outside Great Britain). These Regulations amend those Regulations by extending them to persons employed outside Great Britain.
