Counter-Terrorism and Security Bill

It is necessary to protect public security while avoiding miscarriages of justice. Does my hon. Friend accept that, in a number of cases, the clear finding of the Special Immigration Appeals Commission—the court, a secret court, that will probably consider these matters—has been that the Home Secretary of the day has made a mistake, sometimes on the basis of fallacious evidence and sometimes on the basis of straightforwardly bogus evidence presented by the intelligence agencies? The protection against that, surely, is a court, even if it has to be a secret court.
