Kenya's electoral authorities said on Wednesday they had not received formal notice that opposition leader Raila Odinga had quit the presidential race re-run set for October 26, so regarded all original candidates as still on the slate.
However, the Supreme Court has previously ruled that only the petitioner and respondent in the case challenging the election outcome should stand in a rerun, and this decision is likely to stand.
"IEBC has been forced into urgent meeting with legal experts", reported the daily.
The court elevated Aukot, who ran in the August election, to the level of major candidate in the October vote to preserve the constitutional mandate of an election.
Uhuru Kenyatta and Raila Odinga were due to face off in a repeat election later this month after the Supreme Court annulled an August ballot - in which the president Kenyatta was declared the victor - due to election irregularities and ordered the election to be conducted within 60 days.
The commission said it understood the anxiety surrounding the electoral procedure - earlier, eight people were hurt after Kenyan police fired teargas in running battles with opposition protesters who burned tyres and lobbed stones.
IEBC maintained that the repeat election would go on as planned even as the opposition insists a new presidential election must be conducted within 90 days preceded by fresh party nominations.
"The Commission can not compel a candidate to participate in an election".
The Independent Electoral and Boundaries Commission (IEBC) on Wednesday said that Raila had not officially pulled out of the race as he was yet to sign Form 24A as required in the electoral regulations.
Odinga says he is not giving up on standing entirely, but that withdrawing now is necessary to ensure a free and fair election.
