SOCIAL SECURITY
These Regulations contain provisions about the making of claims for, and the payment of, benefits under the Social Security Acts 1975–86 and the Child Benefit Act 1975. They are made before the end of the period of 12 months from the commencement of the enactments under which they are made and are therefore exempt, under section 61(5) of the Social Security Act 1986, from the requirement in section 10 of the Social Security Act 1980 to refer proposals to make the regulations to the Social Security Advisory Committee.
