(b) Notwithstanding Section 860 of the Code of Civil Procedure, the district may, upon the approval of the tax ordinance by the voters pursuant to this title, and for 30 days thereafter, bring an action in the superior court of the county in which the principal office of the district is located to determine the validity of that matter. The action shall be in the nature of a proceeding in rem.

(c) Notwithstanding Section 863 of the Code of Civil Procedure, if proceedings have not been brought by the district pursuant to subdivision (b), any interested person may bring an action within the time and in the court specified by subdivision (b) to determine the validity of that matter.
