Constitution Alteration (Marketing) 1936 was an Australian referendum held in the 1937 referendums which sought to alter the Australian Constitution to remove the restraints on interstate sales of goods imposed on Parliament by section 92 of the Constitution. It was proposed to add a section 92A that excluded "marketing" from the powers of section 92. This was in reaction to the case of James v Commonwealth [1932] AC 578 in which the Privy Council found that the Commonwealth legislation regulating the sales of dried fruit was invalid.
