Kenya's Supreme court set to deliver decision in presidential vote result challenge

Lawyers and observers have started gathering inside the courtroom in the Kenyan capital where six Supreme Court judges are expected to deliver a judgment in the petition challenging the results of the March 4 election which declared Uhuru Kenyatta as Kenya's next president.

Armed police patrolled the area surrounding the court in Nairobi where crowds gathered Saturday afternoon to hear the decision. Tension mounted across Kenya in anticipation of the court's ruling. The judges could uphold or invalidate the victory of Kenyatta, the son of Kenya's first president who faces serious charges at the International Criminal Court.

Lawyers for Kenyatta's challenger, Prime Minister Raila Odinga, charged before the Supreme Court that the election was marred by irregularities and that Kenyatta did not win enough votes to avoid a runoff election.
