# The Immigration (Registration with Police) Regulations 1972, Regulation 11: Production of registration certificates


(1) On the making of any alteration or addition to the local register, the registration officer may require the alien concerned to produce his certificate of registration in order that any necessary amendment may be made thereto.
(2) Any immigration officer or constable may—
(a) require an alien to whom these Regulations apply, forthwith, to either produce a certificate of registration or give to the officer or constable a satisfactory reason for his failure to produce it;
(b) where the alien fails to produce a certificate of registration in pursuance of such a requirement (whether or not he gives a satisfactory reason for his failure), require him, within the following 48 hours, to produce a certificate of registration at a police station specified by the officer or constable,
so, however, that a requirement under sub-paragraph (b) to produce a certificate of registration at a police station shall have effect in substitution for the requirement under sub-paragraph (a) so as to cause that previous requirement to cease to have effect.
