(1) Except as provided in regulation 93 of these Regulations, inland postal packets (other than parcels) which cannot be delivered to the addressee shall, if a name and address 26 appear on the outside thereof, be returned unopened to the person or address indicated, but otherwise shall be opened by the Postmaster General. (2) Where any inland packet upon being so opened is found to contain the name and address of the sender, the Postmaster General shall return the packet to the sender, but otherwise shall destroy it, provided that an enclosure of intrinsic value contained in any such postal packet not found to contain the name and address of the sender shall be retained for a period of three months to abide the claim of the sender, and on the expiry of this period, in lieu of being destroyed, may, if the Postmaster General so directs, be sold by public auction and the net proceeds of sale credited to revenue. (3) Except where express provision is made in these Regulations no additional postage shall be charged on any postal packet returned in accordance with this regulation, but any other charges due shall be paid before delivery.
