NAIROBI (Reuters) - Kenya's opposition coalition went to the Supreme Court late on Friday to challenge the results of a presidential election which it says was rigged.
Election authorities have said that President Uhuru Kenyatta won the Aug. 8 election by 1.4 million votes, but opposition leader Raila Odinga said the results are false. He has not yet presented evidence of fraud.
Lawyers for Odinga's National Super Alliance did not speak to reporters as they entered the court just 90 minutes before it closed for the weekend and the deadline for delivering their petition expired.
Dennis Onyango, a spokesman for Odinga, said part of the case would include a complaint that the electoral commission had been slow to publish scanned copies of papers detailing results from each of the country's 40,883 polling stations.
The Supreme Court has 14 days to hear and determine the petition, a constitutional requirement designed to minimize the period of uncertainty in case of an electoral dispute.
If the court upholds the election, Kenyatta will be sworn in. If Odinga can prove that rigging took place to an extent that would overturn the result, then Kenya must hold another presidential election in 60 days.
At least 24 people have been killed in election-related violence since polling day, many of them shot by police. But while there have been scattered protests in Odinga strongholds, the demonstrations were relatively muted.
International and domestic observers have said the election was largely free and fair.
