Cal. Health & Safety Code § 114925

Whenever the secretary determines that an existing or proposed regulation is inconsistent with any regulation of another agency of the state, he or she may, after consultation with the agencies involved, find that the proposed regulation is inconsistent with a regulation of the other agency and shall issue an order to that effect, in which event the proposed rule or regulation shall not become effective. The secretary may, in the alternative, upon a similar determination, direct the appropriate agency to amend or repeal the existing regulation to achieve consistency with the proposed regulation.
