CA Gov't Code Section 50485.11

Any person aggrieved or taxpayer affected by any decision of the administrative agency or of any governing body of a city or county, may petition a court for a review of the matter in accordance with law. The court shall have exclusive jurisdiction to affirm, modify, or set aside the decision brought up for review, in whole or in part, and if need be, to order further proceedings by the administrative agency. The findings of fact of the administrative agency, if supported by substantial evidence, shall be accepted by the court as conclusive, and no objection to a decision of the administrative agency shall be considered by the court unless such objection shall have been urged before the administrative agency, or, if it was not so urged, unless there were reasonable grounds for failure to do so. In any case in which airport zoning regulations adopted under this article, although generally reasonable, are held by a court to interfere with the use or enjoyment of a particular structure or parcel of land to such an extent, or to be so onerous in their application to such a structure or parcel of land, as to constitute a taking or deprivation of that property in violation of the Constitution of this State or the Constitution of the United States, such holding shall not affect the application of such regulations to other structures and parcels of land.
