In accordance with the Asylum Act, an asylum seeker, either at the airport or land border, “who does not meet the legal requirements for entering national territory” can be detained for up to 7 days for an admissibility procedure. If SEF takes a positive admissibility decision or if no decision has been taken within 7 working days, the applicant is released. If the claim is deemed inadmissible or unfounded in an accelerated procedure, the asylum seeker can challenge the rejection before the administrative courts with suspensive effect and remains detained for up to 60 days during the appeal proceedings. However, after 60 days, even if no decision has yet been taken on the appeal, SEF must release the individual from detention and provide access to the territory. The maximum detention period of 60 days is equally applicable in instances where the application is made from detention at a CIT due to a removal procedure.
In the 2019 report of the National Preventive Mechanism, the Ombudsman reported that following consultations with other countries, it was concluded that Portugal was the only one detaining persons in airport detention facilities for more than 48 hours.
Official information on the average duration of detention of asylum seekers is not available. Furthermore, due to the changes to the operational practice regarding detention within the context of border procedures, CPR cannot reliably estimate the duration of detention of children (accompanied and unaccompanied).
Even though CPR is not aware of instances where the maximum detention duration was exceeded in the case of asylum seekers, in 2017 the Ombudsman raised concerns regarding isolated instances of detention of third-country nationals beyond the 60-day time limit with respect to CIT – UHSA; the legal status of such persons was not specified. More recent information on this aspect is not available.
