Counter-terrorism and Security Bill

Alas, I am not quite at the same stage of happy reassurance as my right hon. and learned Friend the Member for Beaconsfield (Mr Grieve). Will my right hon. Friend reassure me that the additional judicial step will not mean that, in the time we understand it will take for a return to be made, people can get back into the country while legal proceedings are ongoing? The purpose was to say to those with a family member subject to terrorist infiltration that if they went abroad it would be a one-way ticket. My concern is that this additional legal step might stop that in some cases.
