Attempts to modify the constitution
Zelaya came to international attention in June 2009 when he was overthrown in a military coup and forced into exile. The crisis that led to his removal from office centered around the question of whether changes would be made to the 1982 Honduran Constitution. Zelaya proposed a national poll to gauge interest in constitutional change, which provoked a fierce reaction from opposition parties. Those responsible for the coup justified their actions on the grounds that Zelaya's interest in potentially convening a constituent assembly to draft a new constitution was illegal, and alleged that his real motive was to increase his time in office. Zelaya denied that his motive was to stay in office, stating that he intended to step down in January 2010 as scheduled, noting that his successor would be elected at the same time the vote on whether to convene a constituent assembly would occur.
Under constitutional law, the President of Honduras can amend the constitution without a referendum if a congressional majority exists. However, eight articles cannot be amended, including those related to term limits, the permitted system of government, and the process of presidential succession.
Because the president can amend 368 of the 375 articles in the Honduran constitution without calling a constituent assembly, some suspected that Zelaya's true intention was to extend his rule. One-time Christian Democrat presidential candidate Juan Ramón Martínez argued that Zelaya was attempting to discredit parliamentary democracy, saying, "There appears to be a set of tactics aimed at discrediting institutions... he has repeated on several occasions that democratic institutions are worthless and that democracy has not helped at all".
On 11 November 2008, following requests from multiple Honduran groups for the convening of a constituent assembly,
Zelaya issued a decree organizing a poll to decide whether the electorate wanted a fourth ballot box installed at polling places for the upcoming 29 November 2009 general election – an addition to the usual three for presidential, congressional, and municipal candidates. The fourth ballot would ask voters whether to convene a National Constituent Assembly for the purpose of writing a new constitution. In March 2009, Zelaya announced that he first wanted to have a preliminary poll – he suggested 28 June 2009 as a date – to ask voters whether they wanted the fourth ballot to be included in the November 2009 election.
There has been considerable debate as to whether Zelaya's call for a poll about whether to organize a constituent assembly was legally valid according to the 1982 Constitution. Article 373 of the Constitution states that the Constitution can be amended by a two-thirds majority of the normal National Congress. Only eight articles cannot be amended in this fashion; they are specified in Article 374 of the Constitution and include term limits, system of government that is permitted, and process of presidential succession.
As Congress can amend 368 of 375 articles without any constituent assembly, some observers charged that Zelaya's true intention of holding a referendum on convening a constitutional convention on the same date as his successor's election was to extend his term of rule. In a newspaper interview shortly before his removal from office, Zelaya stated that he had every intention of stepping down when his term ends in January 2010.
The Supreme Court, without deciding on the constitutionality of the poll, ruled that a lower court ruling blocking the referendum was lawful.
The Supreme Court's ruling was supported by Congress, the country's attorney general, top electoral body, and the country's human rights ombudsman, who all said that Zelaya violated the law. Despite the opposition of the other branches of the government, Zelaya moved forward with his plan to hold the poll on 28 June 2009. In Honduras the military assists with election logistics; in late May 2009, Zelaya requested military help to distribute ballot boxes and other materials for the poll. The chief of the military, General Romeo Vásquez Velásquez, refused to carry this order out. In response, Zelaya dismissed Vásquez on 24 May. Subsequently, defense minister Edmundo Orellana and several other military commanders resigned in support of Vásquez. Both the Honduran Supreme Court and the Honduran Congress deemed the dismissal of Vásquez unlawful.
By 25 June, the newspaper La Tribuna reported that the military had deployed hundreds of troops around Tegucigalpa, to prevent possible disturbances by organisations that support Zelaya and with the exception of leftist organizations, "all sectors are publicly opposed to the consultation, which has been declared illegal by the Prosecutor and the Supreme Court". The troops were deployed from the First Infantry Battalion, located 5 km east of the city, to the vicinity of the presidential residence in the west, and the airport, in the south. There is some doubt, however, that Zelaya ever actually fired Vásquez. CNN news on 27 June reported that Zelaya on 24 June had said that he would fire Vásquez; but that on 26 June Zelaya said that he had never carried out his threat and the general had not been fired. "I didn't do it", he told CNN.
The Congress, the attorney general, and the top electoral tribunal declared Zelaya's proposed referendum illegal. Congress began to discuss impeaching Zelaya. On 27 June and again on 30 June 2009, thousands of protesters opposed to Zelaya's impeachment marched through the capital city.
