Kenya's Supreme Court on Saturday ruled to uphold the victory of president-elect Uhuru Kenyatta, whose win was challenged by his leading contender, Prime Minister Raila Odinga.

Kenyatta, the son of Kenya's founding post-colonial leader, Jomo Kenyatta, had won the March 4 poll with 50.07 percent of the vote. The .07-percent margin enabled him to avoid a run-off with Odinga.

Odinga had secured 43.3 percent and had petitioned the court to nullify the poll.

The six Supreme Court judges had 14 days, ending Saturday, to rule on the challenge of Odinga and his Coalition for Reform and Democracy (CORD) coalition.

There was tight security at the Supreme Court. Post-election violence in 2007 left more than 1,000 people dead and forced tens of thousands of others to flee their homes. Kenyatta and his running mate, William Ruto, face trial at the International Criminal Court on charges of crimes against humanity for their alleged role in fueling the violence.

Kenyatta will be sworn in April 9 as Kenya's forth president since independence in 1963.
