In a related development, President Uhuru Kenyatta on Monday welcomed Odinga's reported plan to withdraw from October 26 repeat election.
Opposition leader Raila Odinga and his supporters have turned their ire on the election board for its role in the canceled poll.
The court ruled the elections were flawed and said new polls must be conducted within 60 days.
Following the withdrawal of the NASA presidential candidate, the Commission and the legal team are meeting and will communicate way forward.
IEBC has "refused, neglected or failed to put in place mechanisms to correct illegalities and irregularities cited by Supreme Court during the nullification of the August election".
But Mr Kenyatta said the election will go ahead regardless.
"We are trying to prevent a crisis should there be no elections", he said.
"We are filling the Jubilee box". The re-run had originally been scheduled for 17th October but was delayed in late September as the IEBC sought more time for reforms.
The IEBC would then go ahead and hold the election by printing the ballots with the Nasa candidate therein and supervise voting on October 26 and thereafter declare a victor.
"What Odinga wanted was at first extensive reforms at the electon commission".
"If I choose not to participate in a pre-rigged electoral process, no court can order me to do so", Odinga declared.
Odinga's opposition alliance is threatening to boycott the poll unless the election board changes some personnel.
"But Odinga says that the IEBC has refused to even listen to the some of the demands - demands that the NASA coalition says are reasonable - that they have been making".
Odinga later emerged from the meeting and maintained that they have zero confidence in the electoral body to deliver free and fair elections, saying that the talks with the agency were not fruitful and they had not reached any agreement.
