EU countries can detain asylum seekers far from their borders and keep them in custody beyond the initial screening phase, the European Court of Justice has ruled, in a decision that reinforces the bloc’s new migration framework.
An asylum seeker may be held in a detention centre located within a member state’s territory — not only at its external borders — while their application is processed, the European Court of Justice has ruled in a set of joined cases (C-50/24 to C-56/24).
The judgment has immediate implications for how EU countries organise so-called “border procedures” and aligns with the logic of the European Pact on Migration and Asylum, due to fully enter into force in June.
More flexibility for member states
In practical terms, the ruling gives governments greater flexibility in managing asylum procedures. Detention is no longer tied to facilities at borders or airports: member states may instead rely on centres located anywhere within their territory.
The Court also clarified that detention does not necessarily end with the conclusion of the initial border phase. It may continue, particularly where applications are still being examined as a priority or where there is a risk that the applicant may abscond. In other words, there is no automatic release once the border procedure ends.

However, the Court drew clear limits. Detention cannot be applied systematically and must always be justified on a case-by-case basis. Authorities must demonstrate that the measure is necessary and proportionate in each individual situation.
Applicants must also be informed when their legal status changes, and all procedural guarantees under EU law must be respected. While evidence gathered during the border phase remains valid in subsequent stages, applicants retain the right to challenge or supplement it.
A ruling that reinforces, but constrains, the Migration Pact
The judgment effectively confirms the framework of the European Pact on Migration and Asylum, endorsing member states’ ability to organise detention inland and ensure continuity between procedural phases.
At the same time, it underscores that detention remains an exceptional measure. Even under the new system, authorities must carry out a rigorous individual assessment in every case.
This highlights an underlying tension in EU migration policy: the political aim of accelerating procedures and strengthening border control versus the obligation to safeguard personal liberty and ensure effective access to protection.
From Belgium to Luxembourg
The ruling stems from a 2023 case in Belgium involving asylum seekers from countries including Mali, Syria, Brazil and Libya who applied for international protection upon arrival at Brussels Airport.
Belgian authorities initially placed them in the EU’s border procedure, denying formal entry and holding them in detention centres within the country. After the deadline for this phase expired, detention was extended on other legal grounds — notably the risk of absconding — while their applications continued under an accelerated procedure.
Several applicants challenged both the continuation of their detention and the use of facilities located away from the border. A Belgian court subsequently referred questions to the European Court of Justice, asking whether EU law permits such inland detention and continuity between procedural phases. The Court has now answered in the affirmative, but within strict limits.
