The Constitution Alteration (Retirement of Judges) Bill 1977 was a successful proposal to alter the Australian Constitution to introduce a retirement age of 70 for federal judges. It was put to voters for approval in a referendum held on 21 May 1977. After being approved in the referendum, it received the royal assent and became law on 29 July 1977.

Subject to this section, the maximum age for Justices of any court created by the Parliament is seventy years. The Parliament may make a law fixing an age that is less than seventy years as the maximum age for Justices of a court created by the Parliament and may at any time repeal or amend such a law, but any such repeal or amendment does not affect the term of office of a Justice under an appointment made before the repeal or amendment. A Justice of the High Court or of a court created by the Parliament may resign his office by writing under his hand delivered to the Governor-General. Nothing in the provisions added to this section by the Constitution Alteration (Retirement of Judges) 1977 affects the continuance of a person in office as a Justice of a court under an appointment made before the commencement of those provisions.
