NASA has dismissed claims that the coalition is yet to serve all parties involved in their presidential petition with the suit.
Lawyer Paul Mwangi said on Sunday that all parties have been served.
This was after IEBC said the coalition is is yet to serve them with the petition challenging their declaration of President Uhuru Kenyatta as the August 8 poll winner.
“Attempts to collect it from their lawyers on record proved futile as their offices were closed,” the electoral agency said.
In his response, Mwangi, asked Kenyans to ignore the “mischievous claims”.
The lawyers who drafted the case also ran an advert in The Standard notifying the respondents of the case.
The coalition filed a petition disputing the presidential results at the Supreme Court on Friday.
It had a deadline of four days from the day they filed the petition to serve all parties with a copy.
After serving the copy, the lawyers of the parties have until Friday next week to respond to the petition.
This is before Supreme Court judges sit to determine whether the case is worth hearing.
Raila Odinga and Kalonzo Musyoka, in the petition, want IEBC ordered to conduct a fresh presidential election.
This is if the Supreme Court finds fault in the August 8 polls.
The petitioners want the fresh polls done in strict conformity with the Constitution and the Elections Act.
They also want that respondents be held culpable for jointly and severally committing election irregularities.
The duo is also seeking a specific order for scrutiny of the rejected and spoilt votes.
Raila and Kalonzo also want a declaration that the rejected and spoilt votes count toward the total votes cast.
Raila also wants the court to order for scrutiny and audit of all the returns of the presidential election.
This is including but not limited to forms 34A, 34B and 34C.
They are also praying for order for scrutiny and audit of the system and technology used by IEBC.
Among them are the KIEMS kits, server and website portal.
