Opposition leader and then-mayor of Antananarivo, Andry Rajoelina, led a movement in early 2009 in which Ravalomanana was pushed from power in an unconstitutional process widely condemned as a "coup d'état". In March 2009, Rajoelina was declared by the Supreme Court as the President of the High Transitional Authority, an interim governing body responsible for moving the country toward presidential elections. In 2010, a new constitution was adopted by referendum, establishing a Fourth Republic, which sustained the democratic, multi-party structure established in the previous constitution.
