Gov. Code, § 51294.2

If any local governing body administering an agricultural preserve within 90 days after receiving a request pursuant to Section 51294.1 has not approved or agreed to the location of water transmission facilities as provided in Section 51294.1 or in subdivision (a) of Section 51293, the public agency making such request may file an action against such local governing body in the superior court of one of the counties within which any such body has failed to approve the location of facilities or the acquisition of land therefor, to determine whether the public agency proposing the location or acquisition has complied with the requirements of Section 51292. If the court should so determine, the provisions of Section 51292 shall not apply to the location of water transmission facilities, nor the acquisition of land therefor, in any of the counties into which they shall extend, and no writ of mandamus shall be issued in relation thereto pursuant to Section 51294. For the purposes of this section, the county selected for commencing such action is the proper county for the trial of such proceedings. In determining whether the public agency has complied with the requirements of Section 51292, the court shall consider the alignment, functioning and operation of the entire transmission facility.

Courts shall give any action brought under the provisions of this section preference over all other civil actions therein, to the end that such actions shall be quickly heard and determined.
