2003 Colombian constitutional referendum

Whilst all fifteen proposals were approved by voters, only one question had a sufficient numbers of votes to pass the 25% quorum requirement.

[1] After taking office in August 2002, President Álvaro Uribe put forward several constitutional reforms.

The Congress approved the proposals on 20 December 2002, but also suggested several changes, including reducing the size of the Chamber of Representatives and the Senate by a fifth rather than creating a unicameral Congress, and forcing parties that received less than 2% of the vote in elections to disband.

Uribe subsequently signed the changes into law, and they were submitted to the Constitutional Court on 22 January 2003.

[1] Following the referendum, President Uribe objected to the presence of 700,000 voters on the electoral roll, whose removal would have meant nine of the fifteen questions passing the quorum.
