2009 Honduran constitutional crisis
The 2009 Honduran constitutional crisis was a political crisis in Honduras over plans by President Manuel Zelaya to hold a popular referendum to either rewrite the Constitution of Honduras or write a new one. Zelaya's planned vote to change the constitution faced opposition from a majority of the government, including the Supreme Court of Honduras and prominent members of Zelaya's Liberal Party, as it could lead to the re-election of Presidents which is permanently outlawed by the Honduran constitution.
