This event exposed the sweeping detention powers introduced by the Illegal Migration Act 2023 and what this means for asylum-seekers. We considered the effect of s11 and s12 of the Act, including the codification of Hardial Singh and ‘grace periods’, the new ‘Powers of Detention’, and the impact these changes will have for unaccompanied asylum-seeking children.
