Case summaries

1. A change of the destination country in a return decision by an administrative authority should be regarded as a new return decision requiring an effective remedy in compliance with Article 47 CFREU.

2. The national legislation providing for a safe transit country ground applicable in the present case is contrary to EU law.

3. The obligation imposed on a third-country national to remain permanently in a closed and limited transit zone, within which their movement is limited and monitored, and which the latter cannot legally leave voluntarily, in any direction whatsoever, constitutes a deprivation of liberty, characterised as "detention" within the meaning of the Reception Conditions (RCD) and Returns Directives (RD).

4. Neither the RCD nor Article 43 of the Asylum Procedures Directive authorise detention in transit zones for a period exceeding four weeks.

5. Detention under the RCD and the RD must comply with the relevant guarantees under EU law including being based on a reasoned detention decision; consisting of a measure of last resort, following an individualised assessment of the case, its necessity and proportionality; and effective judicial review should be available. An applicant for international protection cannot be held in detention solely on the ground that they cannot support themselves. Where detention is found to contravene EU law, domestic courts may release the applicant and order the authorities to provide accommodation in line with the RCD provisions. They are empowered to do so, even if they have no clear jurisdiction under national law.

The concept of family life under Article 8 ECHR and under the Portuguese Constitution requires the existence of an effective connection between the individuals, which also presupposes the existence of a financial interdependency.
