California Code, Revenue and Taxation Code - RTC § 8716

(a) A permit shall be held only by persons actively engaging in or conducting a business as a vendor of fuel taxable under this part. Any person not so engaged shall forthwith surrender his or her permit to the board for cancellation. The board may revoke the permit of a person found to be not actively engaged in or conducting a business as a vendor of fuel taxable under this part.

(b) If the permit holder who transfers a business does not notify the board of the transfer, or deliver the permit to the board for cancellation, and the transferee, with the permit holder's actual or constructive knowledge, uses the permit in any way, the transferor shall be liable for taxes under this part, interest computed as specified in Section 8777, and those penalties imposed pursuant to subdivision (c).

(c) The transferor shall be liable for penalties incurred by the transferee under Sections 8779, 8876, and 9352, but shall not be liable for penalties incurred by the transferee under Sections 8780 and 9353. However, the board may, at its discretion, relieve the transferor from liability for penalties incurred by the transferee.
