These Regulations bring into operation the code of practice (“the Code”) issued under paragraph 18(1) of Schedule 1 to the Counter-Terrorism and Security Act 2015 (“Schedule 1”). Schedule 1 provides police officers, immigration officers and customs officials with powers to both seize and retain travel documents of persons at ports. Paragraph 18(1) of Schedule 1 requires the Secretary of State to issue a Code of Practice with regard to the exercise of functions under Schedule 1 and in particular in relation to: the procedure for making designations in respect of officers; the training to be undertaken by officers; the exercise by officers of functions under Schedule 1; the information to be given to a person subject to the exercise of powers under Schedule 1 and the process for disclosure of that information; and reviews of the exercise of the power to retain documents. The Code, which these Regulations bring into operation, satisfies these requirements.
