Question to the Home Office:

To ask the Secretary of State for the Home Department, what estimate his Department has made of the number of people detained by UK Visas and Immigration who had an outstanding (a) appeal, (b) application and (c) judicial review in (i) 2017 and (ii) 2018.

The specific information requested could only be supplied at disproportionate cost.

Immigration detention is used as a last resort, sparingly and for enforced return where the person concerned has no right to remain in the United Kingdom. Each case is assessed by Home Office officials in line with published detention policy and there must be a realistic prospect of removal within a reasonable timescale.

It would be rare for detention to occur when there is any outstanding appeal, application or Judicial Review. Those who are detained could be notified of the outcome of an appeal, application, or Judicial Review; but this would be those applications, appeals or Judicial Reviews that are raised or lodged from within detention.
