These rules amend the Superannuation (Local Government Staffs) (National Service) Rules, 1949, as amended by the Superannuation (Local Government Staffs) (National Service) (Amendment) Rules, 1951, which provide for the reckoning of national service for the purpose of the Local Government Superannuation Act, 1937, or a local Act scheme. The principal amendments are the deletion of references to benefits under the Act of 1937 or a local Act scheme (leaving references to benefits as general references to local government superannuation benefits); and the introduction of references to service under a local Act scheme corresponding to non-contributing service under the Act of 1937. The rules also substitute for the existing definition of “national service” the definition of “national service” used in the Justices' Clerks and Assistants (Superannuation) Regulations, 1954.
