A constitutional referendum was held in Bolivia on 25 January 2009, postponed from the initially planned dates of 4 May 2008 and then 7 December 2008. Drafted by the Constituent Assembly in 2007, the new constitution was approved in the referendum according to an exit poll by Ipsos Apoyo for La Razón and ATB, a Bolivian television network. Furthermore, it required early elections to be held on 6 December 2009.
Under President Evo Morales, the Constituent Assembly was elected on 2 July 2006. The referendum should originally have taken place on 6 August 2007, but the Assembly's validity was extended until 14 December 2007. On 9 December 2007, the Assembly approved the draft and on 14 December, the Assembly officially handed the constitution draft over to the National Congress.
The National Congress adopted the law on 28 February 2008 calling for the referendum on 4 May 2008 even though many opposition members chose to stay away during the vote. A law was also approved and signed by Morales that permitted only Congress to call departmental referendums, thereby barring the departmental referendums on autonomy that had also been called for 4 May.
On 7 March 2008, the National Electoral Court suspended the referendum, along with the opposition's regional referendums, saying that there was not enough time for adequate electoral preparations. Nonetheless, the government of Santa Cruz Department went ahead and held its autonomy referendum as planned, ignoring the Court's interdiction on all referendums. Beni Department and Pando Department held their referendums on 1 June 2008.
In a decree on 28 August 2008, Morales declared that the referendum would be held on 7 December 2008.
In April 2013, the Supreme Court ruled that the first term of President Evo Morales did not count towards constitutional term limits as the constitution of Bolivia had since been amended, thus allowing Evo Morales a third term.
Following unrest in Pando, the government and the opposition held talks which resulted in a compromise reached on 20 October 2008. They agreed to hold the referendum on 25 January 2009 and early elections on 6 December 2009; Morales in turn promised he would not run again in 2014 after his likely reelection in 2009, despite the fact that he would be allowed to do so under the new constitution.
