In any administrative action to revoke or suspend an automobile dismantler’s license:
(a)
Proof that a stolen vehicle of a type subject to registration under this code, or a part thereof, was found in the possession of, or upon the premises of, the dismantler shall constitute in evidence a prima facie presumption that the dismantler had knowledge that the vehicle was stolen. This presumption may be rebutted by satisfactory evidence that the dismantler has complied with paragraphs (1), (2), (3), and (5) of subdivision (a) of Section 11520.
(b)
Proof that a vehicle of a type subject to registration under this code is found in a partially dismantled condition in the possession of, or upon the premises of, the dismantler shall constitute in evidence a prima facie presumption that the vehicle was partially dismantled by the dismantler. The presumption may be rebutted by a business record of the dismantler reflecting the partially dismantled condition of the vehicle on the date of acquisition.
