The chief procurement officers shall by rule establish procedures to be followed in resolving protested solicitations and awards and contract controversies, for debarment or suspension of contractors, and for resolving other procurement-related disputes. At a minimum, the established procedures must include the requirement that the chief procurement officer resolve the protest by means of a written determination within 30 days of receiving all relevant requested information, unless an action concerning the protest has commenced in a court or administrative body, in which case, the chief procurement officer may defer resolution of the protest pending the judicial or administrative proceeding.
