My question involves a traffic citation from the state of: CA

(C) (i) When the vehicle owner or his or her agent claims the vehicle, the towing company prior to payment of a towing or storage charge shall provide a photocopy of the written authorization to the vehicle owner or the agent.

My question is if the towing company did not provide me with this, is this enough to win or can they just provide it afterward and not be affected by this.
