1951 Uruguayan constitutional referendum

A constitutional referendum was held in Uruguay on 16 December 1951.[1] The proposed amendments to the constitution were approved by 54% of voters.


The proposed changes to the constitution were presented to the General Assembly on 31 June 1951. The Chamber of Deputies approved it by a vote of 85 to 14 on 10 October, whilst the Senate approved it by a vote of 26 to 4 on 26 October.[1]

The amendments would:[1]

  • reintroduce the colegiado system of government, giving six seats on the National Council of Government to the largest party and three to the second largest party.
  • provide for a bicameral General Assembly elected by proportional representation.
  • retain the use of the lema system.
  • allow petitions for constitutional amendments signed by 10% of registered voters, and allow the General Assembly to put forward a counter-proposal to the proposed amendments.
