The Immigration Bill would risk seriously restricting judicial oversight of the Home Office’s powers of immigration detention. The Bill would abolish the system of ‘bail addresses’ that enables destitute migrants to challenge their detention through bail applications to the First-Tier Tribunal. As a result, in a significant proportion of cases the Home Office could face no judicial scrutiny of detention until the point at which an expensive and time-consuming unlawful detention challenge can be brought in the High Court.
