Counter-Terrorism and Security Bill

I understand the system that my right hon. Friend is putting in place of managed return, but what is not clear in the Bill is the system that will be present to enable that managed return requirement to be challenged. I wonder whether she can help the House on that point. It seems to me that there must be a mechanism by which a person who is told that they have to return in a particular way can challenge it on their return to this country, and do so expeditiously, if it is not to be an unwarranted interference with their rights.
