12. Claims by third party:
(1) Where any claim is preferred, or any objection is made to the seizure of any property under section 7 on the ground that such property is not liable to seizure, the Designated Authority before whom such property is produced, shall proceed to investigate the claim or objection:
Provided that no such investigation shall be made where the Designated Authority considers that the claim or objection is designed to cause unnecessary delay.
