California Code, Health and Safety Code - HSC § 113220

There shall be no administrative appeal of the secretary's decision regarding a request for an extension. Judicial review of the decision of the Secretary of the Resources Agency on any request for an extension may be made by the manufacturer. In addition, any member of the public, without damages, at his or her own expense, has standing to bring an action for the purpose of inquiring into the validity of a decision of the secretary on the grounds of the abuse of discretion where the findings are unsupported by the evidence. This section shall not be construed to prohibit the use of any other remedy available under any other provision of law.
