Regulation 70 Use of codes in records and messages &c
Where any information is to be included in any communication issued under or contemplated by these Regulations, that information may be given by means of a code agreed between the parties to the communication.
Any entry on any record or register to be made under these Regulations may, subject to the provisions of any other enactment to the contrary, be made by the use of a code, provided that a key to the codes used is maintained at the place where the register or record is kept and (where the register or record is open to the inspection of any person) is made available with the register or record for inspection. Where any person may require the provision of a copy of the register or record or part thereof, the key shall accompany any copy so provided.
