“The presidential election which held on August 8 was not conducted in accordance with the constitution,” said David Maraga, ruling in favour of the opposition, which challenged the declaration of President Uhuru Kenyatta as the winner.

Maraga said this was a majority decision, with two judges dissenting.

The shock ruling was a rare example of a poll result being overturned, with Maraga saying the election commission (IEBC) “failed, neglected or refused to conduct the presidential election in a manner consistent with the dictates of the constitution”.

Maraga said this had compromised the “integrity of the entire presidential election”.
