In the petition, Odinga asks the court to nullify the vote’s outcome on several grounds, including a mismatch between the turnout figures and the result, and failure by the commission to tally ballots from 27 constituencies as required by law.
“The final result… was therefore not complete, accurate, verifiable or accountable and cannot be the basis for a valid and legitimate declaration,” the petition said.
The election commission is split: the chairman announced that Deputy President William Ruto won by about 233,000 votes, but four out of the seven commissioners dissented, saying results were not aggregated correctly.
Any perceived misstep in the ruling by Koome or the six judges she presides over could damage public faith in the judiciary and imperil the peaceful transfer of power in East Africa’s richest and most stable nation.
The dispute has raised tensions in a nation with a history of deadly election disputes.
“We urge the judiciary to remain an impartial arbiter,” the Angaza Movement, a Kenyan civic and human rights consortium, said on Friday, adding the “tranquillity and peace of the nation” depended upon it.
The stakes are also high for the judges themselves: when Kenya’s Supreme Court nullified the 2017 election results, judges faced a torrent of abuse, were called “crooks” by the president and one of their bodyguards was shot and injured.
Koome, appointed in May 2021 by outgoing President Uhuru Kenyatta, has a reputation for integrity.
Months after her appointment, she quashed broad constitutional reforms backed by both Odinga and Kenyatta, which were widely seen as an attempt to sideline Ruto.
Koome’s ruling prompted praise even from critics like Ahmednasir Abdullahi, a lawyer who has frequently questioned Koome’s independence and who supports Ruto.
“On the whole, good judgment by the Supreme Court,” he tweeted, praising Koome and a second judge for being “outstanding in their reasoning”.
CHALLENGING POWER
Four of those judges remain on the Court. The chief justice retired and Koome replaced him.
Koome – who has 34 years of legal experience – cut her teeth representing political detainees like Odinga when he protested against state repression in the 1980s and 90s.
In Odinga’s stronghold of Kisumu, faith in the courts helps keep protesters off the streets.
“Many years ago … courts seemed to be controlled by the government. But today’s courts have come out to be more independent,” said carpenter Meshack Nyamema.
Koome, 62, is already a trailblazer: her appointment made her the first female head of any Kenyan branch of government. She often discusses her Christianity and liberal social views.
One of 18 children from a polygamous family of subsistence farmers, Koome co-founded and chaired the Federation of Women Lawyers.
In another departure from orthodoxy, in 2019 she supported a ruling that it was not illegal to identify as gay. Gay sex is punishable by 14 years in jail.
This May, Koome used a national prayer breakfast to warn against settling election disputes on the streets.
“I pray for those who might be tempted to divide our nation for their selfish reasons,” she said. “This country belongs to everyone, and not just politicians.”
Last week the election commissioner declared
The commission, its chairman and Ruto have four days to respond to Odinga’s claims through court filings.
