Cal. INS § 1561

Any law or ruling of any state of the United States or any foreign country which shall attempt to assume jurisdiction over, or to authorize regulation or supervision of, a noninsurance affiliate of a domestic insurer, where such attempt is based solely upon the domestic insurer applying for or holding a certificate of authority to do business in such state or foreign country, whether such attempt be by registration or through disclosure, reports, examinations, or other devices imposed on either the insurer or its noninsurance affiliate, directly or indirectly, shall be deemed to be an unreasonable law. Upon finding that such unreasonable law has been applied to a domestic insurer or its noninsurance affiliate by such state or foreign country, the commissioner may refuse to grant an initial certificate of authority, but not a renewal of an existing certificate of authority, to an insurer organized under the laws of such state or foreign country thereafter applying to him for authority to do business in this state.

As used in this section, “affiliate” means a person that, directly or indirectly, through one or more intermediaries, controls, or is controlled by, or is under common control with, the domestic insurer.
