For the purpose of these Regulations, the obliteration of any one stamp on any automatic weighing machine shall, subject to paragraph (2) below, be deemed to be the obliteration of all other stamps on that machine.

Where the stamp on one automatic weighing machine forming part of an interconnected system is obliterated, paragraph (1) above shall not apply so as to prevent the system or any other machine in the system being used provided that the integrity of the remainder of the system is unimpaired.
