The deadline for filing an action directly in the district court is ninety days after the complainant receives notice of the last action the commission will take on the complaint or charge. When entering the last action on the complaint or charge, the commission shall issue written notice of such ninety-day deadline to the complainant by certified mail, return receipt requested. The last action on the complaint or charge includes the issuance of the final order after hearing, the determination of reasonable cause or no reasonable cause, and any other administrative action which ends the commission’s involvement with the complaint or charge.
