Spanish Supreme Court strengthens presumption of minority for migrant youths

Spanish Supreme Court strengthens presumption of minority for migrant youths
Spain’s Supreme Court has handed down a landmark ruling that could alter how thousands of newly-arrived migrant teenagers are treated at the country’s borders and in criminal proceedings. In a judgment dated 29 January but published on 21 February, the high court annulled an earlier Canary Islands ruling that had authorised the trial of a Senegalese boy as an adult on the basis of inconclusive bone-and-dental tests. The court held that when medical age-assessment exams produce a range that straddles 18 years, authorities must adopt the lower age and treat the individual as a minor unless there is clear evidence of fraud.

The decision cites EU Directives on child protection and reiterates long-standing UN guidance that documentary proof from the country of origin carries greater evidentiary value than “intrusive and fallible” radiological techniques. Lawyers have long argued that Spain’s pressure-ridden border posts often default to medical testing and provisional adult detention, placing genuine minors in adult prisons or reception centres for months.

In practical terms, anyone involved in securing or validating travel papers—from guardians seeking family reunification to NGOs arranging safe passage—can turn to VisaHQ for quick, reliable help. Through its Spain-specific portal (https://www.visahq.com/spain/) the service simplifies visa applications, document legalisation and consular appointments, providing real-time updates that cut through the red tape highlighted by the court’s ruling.

Practically, the ruling will oblige police, prosecutors and forensic institutes to review their protocols. Border posts such as Ceuta, Melilla, the Canary Islands and Almería will have to prioritise original birth certificates and consular attestations. Juvenile prosecutors expect a surge in requests to reopen cases in which young migrants were treated as adults despite ambiguous tests.

For regional child-protection services the decision offers welcome clarity. Autonomous communities will gain earlier custody of minors, unlocking EU solidarity funds for shelter and schooling. Businesses that rely on apprenticeship schemes for under-18s—agriculture in Andalusia, hospitality in the Balearics—may also find recruitment easier once the youngsters secure proper documentation.

Human-rights NGOs hailed the verdict as “historic”; the conservative opposition warned it could be exploited by traffickers to coach adults into posing as children. The Interior Ministry said it would update its internal age-assessment circulars within 30 days to ensure uniform application nationwide.
