These Regulations provide that members of the Civil Nuclear Constabulary are persons of a specified description, and therefore law enforcement officers, for the purposes of Chapters 5 and 6 of Part 4 of the Policing and Crime Act 2017 (c. 3). This enables the Civil Nuclear Constabulary to exercise the maritime enforcement powers given to law enforcement officers by Chapters 5 and 6 of Part 4 of that Act.
