19.—(1) Where a veterinary inspector knows or suspects that—
(a)in the case of any animal, the import conditions of a Directive listed in Schedule 4, any additional requirements specified in relation thereto in that Schedule or any additional animal health legislation regulating the import of such animals into Northern Ireland have not been complied with; or
(b)in the case of any animal there is doubt as to its identity,
he may carry out any veterinary checks on that animal which he deems appropriate.
(2) If the checks carried out under paragraph (1) confirm that import conditions referred to in that paragraph were not complied with in the case of any animal then the provisions of regulation 16 shall apply and, in the case of the exercise of a power to isolate the animal, a veterinary inspector may additionally require the placing in isolation of other animals which have been in contact with the imported animal.
