Over the weekend, Honduras was about to hold a referendum on whether its Constitutional prohibition against a sitting president running for a second term should be modified. The referendum was proposed by President Zelaya, whose term in office expires next year; an election is to be held in November.
The Constitution expressly states that its provisions concerning the presidential term of office and prohibiting reelection are among the very few provisions not subject to change.
Title VII, with two chapters, outlines the process of amending the constitution and sets forth the principle of constitutional inviolability. The constitution may be amended by the National Congress after a two-thirds vote of all its members in two consecutive regular annual sessions. However, several constitutional provisions may not be amended. These consist of the amendment process itself, as well as provisions covering the form of government, national territory, and several articles covering the presidency, including term of office and prohibition from reelection.
The text, in Spanish, of Article VII is provided in a footnote. Despite a ruling by the Honduran Supreme Court that he could not constitutionally do so, President Zelaya determined to go forward with the referendum.
The news reports on what happened next are often unclear and frequently contradictory; to some extent, the massive media coverage of Michael Jackson's death may have displaced them. Here, however, is my best effort at offering a summary distilled from multiple sources.
Sometime earlier this year, President Zelaya decided that the Constitution should be amended to permit him to run for another term. The Congress, controlled by the party of which President Zelaya is a member, refused to go along. The Bolivarian Republic of Venezuela provided the necessary ballots, and President Zelaya ordered the military to distribute them for a referendum to be held on 28 June. The Supreme Court determined that the referendum was violative of the Constitution, and ordered the top military commander, Gen. Romeo Vásquez Velásquez, neither to distribute the ballots nor in any other way to carry out the logistics of the vote as the military would normally do in elections. General Vásquez Velásquez so advised President Zelaya, who promptly fired him. The Supreme Court ordered him reinstated, and President Zelaya refused. On 28 June, President Zelaya led a group of his followers to the military installation where the ballots were being stored, took them, and had his followers distribute them. The Congress voted unanimously to appoint a committee to analyze the situation and investigate President Zelaya for his refusal to respect the Constitution and the orders issued by other branches of government. He nevertheless carried on with his preparations, and offered only a cosmetic change to the referendum: on Saturday night (27 June); he verbally stated that the referendum would not be binding, but confirmed that it would go ahead as planned the next day. A few hours before the opening of the polling stations, the Supreme Court ordered the president’s arrest and removal from office. The army carried out the order, arrested Mr. Zelaya and transported him to Costa Rica. A reason for doing so was to avoid a bloodbath in the face of the threat of other governments interfering in Honduras’ internal affairs, among them Venezuela and Nicaragua. The likelihood of substantial popular protests over the ouster of Mr. Zelaya seemed small, since Mr. Zelaya had low support — polls showed around 30 percent before his ouster — "as many Hondurans were uncomfortable with his tilt to the left in a country with a long conservative, pro-Washington position." As indicated below, that bloodbath now seems quite possible, largely due to outside interference from Washington, Caracas and elsewhere. The referendum was not held, and the Legislature, in emergency session, unanimously selected its president as the interim President of Honduras as provided by Honduran law, and stated that a presidential election would be held in November, as scheduled. The interim President is of the same political party as former President Zelaya.
The ouster of President Zelaya has frequently been termed a "coup." That seems, to me at least, to stretch the word well beyond its commonly understood meaning. The Honduran military acted to execute the lawful orders of the Supreme Court and with the blessing of the "democratically elected" legislature; I have seen no indication that the military instigated the ouster. Nor is Honduras under military control; it has an interim civilian president, properly selected by unanimous vote of the legislature in compliance with the laws of presidential succession.
