Waititu who vied on The National Alliance Party ticket wants Kidero’s election nullified, claiming there were numerous glaring irregularities.
Kidero was declared winner of Nairobi’s gubernatorial race after polling 692,483 votes, while Waititu emerged second with 617,839 votes.
In the petition filed in the High Court at Milimani, Waititu is seeking orders to block the Independent Electoral and Boundaries Commission (IEBC) from gazetting Kidero as the governor of the capital city.
Waititu alleges electoral malpractices in most polling stations, with some having more ballots cast than total registered voters.
He now wants the court to order the IEBC Chief Executive Officer James Oswago to produce copies of documents used during the Nairobi gubernatorial election within 24 hours.
Among the materials he is seeking include a copy of the voters register used during the elections in Westlands, Ruaraka, Langata, Kibera, Embakasi East, Embakasi South and Mathare constituencies.
He also wants copies of the results of each polling station within the same constituencies.
Waititu is also seeking to be provided with spoilt ballot papers in the specified areas.
High Court Judge Mumbi Ngugi directed Waititu to serve Kidero and the IEBC with the suit papers and set the hearing for Friday, March 15.
