NAIROBI, Kenya’s Supreme Court prepared on Tuesday to review petitions challenging President Uhuru Kenyatta’s victory in last month’s presidential election re-run, in what may be the last chance for legal scrutiny of the vote.

Security was tight outside the courtroom, which has been centre stage for Kenyan politics since it nullified the results of Aug 8’s presidential election. That decision led to the re-run election on Oct 26.

The court has not convened since the day before last month’s election, when it had been due to deliberate on a last-minute request to delay the vote. But that hearing was cancelled because not enough judges showed up to make a quorum.

All six judges are expected to be present for Tuesday’s meeting. The seven-member bench is still missing one of its judges, who fell ill during the hearings related to the August election and has since been receiving treatment.

The judges are expected to announce when proceedings will begin and whether it will hear all three petitions filed – one by a former lawmaker and the other two by civil society organizations.

Two of the petitions filed with the court argue the poll’s outcome is void because the election board did not hold fresh nominations after the Aug. 8 poll was invalidated.

The third petition, filed by a civil society organisation, is a case against the opposition. It seeks to hold them liable for losses incurred because of their demonstrations.

None of the petitions focus on whether the election board was adequately prepared to hold the repeat poll – a central reason cited by the opposition for boycotting the vote.

The court has until Nov. 20 to rule on the petitions. If the election result is upheld, Kenyatta will be sworn in on Nov. 28.

Kenyatta came to power in 2013 and won a second and final term in August, defeating opposition leader Raila Odinga by 1.4 million votes.

Odinga did not contest the repeat vote on Oct 26, saying it would be unfair because the election commission had failed to implement reforms. Kenyatta won with 98 percent of the vote, though opposition supporters staged a boycott and prevented polls from opening in the west of the country.
