If the Department suspends or revokes a registration, the Department may place under seal all controlled dangerous substances that the registrant owns or possesses at the time of the suspension or revocation in accordance with the registration. Unless the court on request orders the sale of perishable substances and the deposit of the proceeds of the sale with the court, a disposition may not be made of controlled dangerous substances under seal until the time for taking an appeal has elapsed or until all appeals end. When a revocation order becomes final, all controlled dangerous substances placed under seal in accordance with this section shall be forfeited to the State.
