I am not sure whether the noble Lord has read the report of the inquiry to which a number of us contributed, but we did quote from the International Detention Coalition about the experience in countries that do not rely so much on detention. The noble Lord seems to be worried about what that might mean in terms of the effect on compliance. The coalition found that alternatives to detention,
“maintain high rates of compliance and appearance, on average 90% compliance. A study collating evidence from 13 programs found compliance rates ranged between 80% and 99.9%. For instance, Hong Kong achieves a 97% compliance rate with asylum seekers or torture claimants in the community, and in Belgium, a pilot working with families facing removal had an 82% compliance rate”.
Alternatives to detention have proved to be very effective and can address some of the concerns of the noble Lord.
