The Supreme Court has nullified the re-election of President Uhuru Kenyatta.

A six-judge bench, by majority decision, on Friday found that the electoral commission failed to conduct the polls according to the Constitution and Elections Act.

"Elections is not an event but a process. After considering the totality of the entire evidence, we are satisfied that the elections were not conducted in accordance to the dictates of the Constitution and the applicable principles," Chief justice David Maraga said.

"That President Uhuru Kenyatta was not validly elected on August 8.".

Judges Ojwang and Njoki Ndung'u dissented while judge Mohammed Ibrahim did not take part in the decision because he is unwell in hospital.

The top court in Kenya, in a bold move, ordered the IEBC to conduct a fresh presidential election within strict confines of the law within 60 days.
