46.These sections make similar provision to the following sections of the PTA: section 13A (inserted by the Criminal Justice and Public Order Act 1994 (c. 33)) and section 13B (inserted by the Prevention of Terrorism (Additional Powers) Act 1996 (c. 7)). They give the police powers to stop and search vehicles and their occupants, and pedestrians, for the prevention of terrorism. As with the powers under the PTA, authorisations apply to a specific area and are for a maximum of 28 days (though that period may be renewed). The main difference is that vehicle stop and search authorisations, as well as pedestrian authorisations, will have to be confirmed or amended by a Secretary of State within 48 hours of their being made, or they will cease to have effect.
