When asylum seekers are detained, they are informed in writing of the detention decision, its reasons and the possibility to lodge an appeal. Those reasons are mostly limited to very general considerations such as “having tried to enter the territory without the necessary documents (at the border)”, or “risk of absconding (in Dublin cases)”. Translation of the detention decision in the language of the asylum seeker is not provided for by law, but in some centres a social interpreter is arranged by the centre’s social assistant on request by the detainee.
While in detention, the CGRS prioritises the examination of the asylum application, although no strict time limit is foreseen. The appeal must be lodged within 10 days after the first instance decision. The Court of Alien Law Litigation (CALL) has already criticized the use of this fast-tracked procedure and annulled the decision of the asylum authorities in a case of an asylum applicant at the border because of the threat to his rights of defence and the principle of equality of arms.
National legislation does provide for judicial review of the lawfulness of detention. Unlike in case of a suspect in criminal cases, an asylum seeker who is detained is not automatically brought before a judge to determine the lawfulness of his or her detention, but he or she can lodge a request to be released with the Council Chamber of the Criminal Court every month. The Council Chamber has to decide within 5 working days, and if this time limit is not respected, the asylum seeker has to be released from detention. An appeal can be lodged against the decision of the Council Chamber before the Indictment Chamber at the Court of Appeal (Chambre des mises en accusation | Kamer van Inbeschuldigingstelling) within 24 hours. Against this final decision, a purely judicial appeal can be introduced before the Court of Cassation.
It is only when the Immigration Office decides to prolong the detention for another month after the applicant has spent already 4 months in detention, that an automatic review by the Council Chamber of the Criminal Court takes place.
The scope of judicial review of detention remains very restrictive. Only the legality of the detention can be examined, not its appropriateness nor its proportionality. This means that only the accuracy of the factual motives of the detention order can be scrutinised i.e., whether the reasons for detention are based on manifest misinterpretations or factual errors or not. Through such a restriction, the Aliens Act prevents an effective judicial control of the conditions of necessity and proportionality it imposes itself. The logic behind this is that the competence to decide on the removal of the foreigner, and as such on the appropriate measures to execute such a decision, lays with the Immigration Office and the CALL, not with the criminal courts. However, an appeal against a “refoulement decision” issued when applying for asylum at the border by the CALL will only be done once the execution becomes imminent, which is only the case once the asylum application has been refused (see Border Procedure).
The scope of the judicial review on the legality of detention measures is almost arbitrary and the Court of Cassation is ambiguous about the interpretation of such legality in its own jurisprudence, by including assessments of conformity of detention with the Return Directive or the ECHR, following the ECtHR’s ruling in Saadi v. United Kingdom. The Council or Indictment Chambers have even sometimes considered the principle of proportionality as part of the legality of a decision, but in most cases, they limit their review to the legal basis for the decision, without ever considering any of the provisions of the Reception Conditions Directive. The fact that the person detained is an asylum seeker or a particularly vulnerable person is generally not taken into consideration as an argument to limit the use of detention. The law that entered into force on 22 March 2018 states that an asylum seeker can be detained if no other less coercive alternative measures can be applied and if it is deemed necessary based on an individual assessment. The same position has already been adopted by the Court of Justice of the European Union in its earlies case law, as a result of which an overly strict interpretation of the Belgian legal framework constitutes a violation of EU law. Previous case law of the Court of Justice of the European Union adopted the same These less coercive measures have not yet been listed by way of Royal Decree. This recent reform remains to be evaluated in practice.
The procedure before the courts is determined in the Law on the Provisional Custody that applies in criminal law proceedings. In practice, the time limits set in the law are respected, unless an appeal at the Court of Cassation is introduced against a judgment ordering release by the Court of Appeal. Since this cassation appeal suspends the detention period and it is not commonly treated within a reasonable time, the detention period can exceed the legal maximum and result in the asylum seeker remaining in detention for prolonged periods. This practice has repeatedly been marked as a violation of Article 5(4) ECHR by the ECtHR.
The European Court of Human Rights examined the legality of the detention and the effectiveness of the remedy provided against the deprivation of liberty and found a violation of the Convention on these points. As such, the Court opposed the case law of the Court of Cassation, which held for many years that an appeal against a decision depriving a person of their liberty is without foundation when, after it has been lodged, the foreign national has been detained based on another separate detention title. Jurisprudence of the Court of Cassation has slightly been amended since a decision of 27th of September 2022 where the Court found that the procedure had to be continued, even though the person had in the meanwhile been released.
The policy note of the government, however, formulates the intention to amend this: “In addition, we are working to provide an effective remedy, whereby both the legality and the expediency of the detention can be reviewed by the courts.” The government is currently making efforts to reform the Migration Code. Recommendation by the Move Coalition on the judicial review of the detention order concern the introduction of automatic judicial review, assignment of territorial jurisdiction to the Council Chamber of the district in which the detention centre is located in order to facilitate the designation of a legal aid lawyer, the applicability of the procedure states in the Law on the Provisional Custody, and specialization of the judges entrusted with the review of the detention order.
