County Assembly Speaker Susan Kihika has 10 days to file a replying affidavit to a suit in which she was sued together with Clerk of the Assembly Joseph Malinda.
Margaret Kiiru, a nominated member of the assembly, went to court and filed a petition seeking to have Ms Kihika declared unfit to hold any public office in Kenya.
Under a certificate of urgency, Ms Kiiru wants the case determined before the August 8 elections.
Kiiru wants Kihika and Malinda to take personal responsibility for the "unlawful and unconstitutional" disbursement of the car loan and mortgage fund.
