PENSIONS
These Rules contain provisions with respect to the superannuation rights of persons transferring between employment which is pensionable under regulations made under section 67(1) of the National Health Service Act, 1946, and pensionable local government employment. The Rules replace (with amendments which, in the main, are consequential on changes in local government superannuation law) similar provisions of the National Health Service (Superannuation) Regulations, 1950. The latter regulations are revoked on 1st October, 1955 (which is also the date of coming into operation of these Rules) by the National Health Service (Superannuation) Regulations, 1955.
