The Supreme Court has nullified President Uhuru Kenyatta's re-election, ordering for a fresh presidential poll in 60 days.
The court stated that IEBC did not conduct free and fair elections but cleared Kenyatta of any malpractice.
They also stated that the irregularities experienced affected the final outcome of the election.
Out of the 7 judges, 2 (Justice Jackton Ojwang' and Njoki Ndung'u) gave dissenting views saying the election was free and fair.
Chief Justice David Maraga stated that the election of President Uhuru Kenyatta is null and void and he was not validly elected.
Odinga's lawyers had asked the court to invalidate Kenyatta's win, saying a scrutiny of the forms used to tally the votes had anomalies that affected nearly 5 million votes.
Kenya's electoral commission had said there was a hacking attempt but it failed. International election observers had said they saw no interference with the vote.
Odinga, a longtime opposition candidate and the son of Kenya's first vice president, had unsuccessfully challenged the results of the 2013 vote.
