The president is elected at the first sitting of Parliament after an election, and whenever a vacancy arises. The president is elected by the National Assembly, the lower house of parliament, from among its members. The chief justice must oversee the election. Once elected, a person is no longer a member of the National Assembly. They must then be sworn in as president within five days of the election. Should a vacancy arise, the date of a new election must be set by the chief justice, but not more than 30 days after the vacancy occurs.
