The duties, responsibilities and other transitional clauses dealing with the presidency are listed in Chapter Three, Articles 79 through 89, of the Constitution. The term for the president is five years, but due to a 1996 referendum, the election that was supposed to occur in 1999 was pushed back to 2001. Under the 1994 constitution, the president could only serve for two terms as president, but due to a change in the constitution, term limits were eliminated. During the course of the office, elections were held in 1994, 2001, 2006, 2010 and on 11 October 2015.
