Cal. Government Code § 65956

(a) If any provision of law requires the lead agency or responsible agency to provide public notice of the development project or to hold a public hearing, or both, on the development project and the agency has not provided the public notice or held the hearing, or both, at least 60 days prior to the expiration of the time limits established by Sections 65950 and 65952, the applicant or the applicant’s representative may file an action pursuant to Section 1085 of the Code of Civil Procedure to compel the agency to provide the public notice or hold the hearing, or both, and the court shall give the proceedings preference over all other civil actions or proceedings, except older matters of the same character. (b) In the event that a lead agency or a responsible agency fails to act to approve or to disapprove a development project within the time limits required by this article, the failure to act shall be deemed approval of the permit application for the development project. (c) Failure of an applicant to submit complete or adequate information pursuant to Sections 65943 to 65944, inclusive, may constitute grounds for disapproving a development project. (d) Nothing in this section shall diminish the permitting agency’s legal responsibility to provide, where applicable, public notice and hearing before acting on a permit application.
