Traffic Act 1987

As soon as practicable after the police officer has made the impounding determination, the police officer must give a copy of it to a senior police officer to review the determination.

The senior police officer must review the impounding determination as soon as practicable and no later than 24 hours after the copy is given to him or her.

At any time before an impounding determination ceases to have effect:

the police officer or senior police officer must revoke the determination if the police officer or senior police officer is satisfied that, at the time of the alleged offence, the motor vehicle was a rental vehicle, or was stolen or otherwise used without the authority of its owner; or

the senior police officer must revoke the determination if the senior police officer is not satisfied the vehicle was used in committing the alleged offence.
