The Holt Government also unsuccessfully attempted to remove section 24 of the constitution (the so-called "nexus clause"), which requires the number of members in the House of Representatives to be "as nearly as practicable, twice the number of senators". The resulting referendum did not come close to passing, with only 40 percent voting in favour nationwide and only one state (New South Wales) recording a majority. All three major-party leaders campaigned for the "Yes" vote, while opposition came mainly from Coalition backbenchers and Democratic Labor Party senators. Supporters of the "No" vote successfully argued that section 24 protected the influence of the Senate, and thus the interests of less populous states and rural areas. Holt did make one other significant legal reform, albeit one that did not require a constitutional amendment. In September 1967, he announced that his government would use section 74 of the constitution to remove the potential for High Court cases to be appealed to the Judicial Committee of the Privy Council. The necessary legislation was not passed until after his death.
