Where an applicant has been allowed to reside only in a specific place but has not complied with that obligation, there still needs to be a risk that the applicant could abscond in order for the applicant to be detained. In all circumstances, special care should be taken to ensure that the length of the detention is proportionate and that it ends as soon as the obligation put on the applicant has been fulfilled or there are no longer reasons for believing that the applicant will not fulfil that obligation. The applicant should also have been made aware of the obligation in question and of the consequences of non-compliance.
