The Spanish Supreme Court recently issued a ruling that reinforces the presumption of minority age for young migrants whose identity may be disputed. This decision, issued on January 29, concluded a case involving a Senegalese youth identified as M.K., whose official documents and forensic evidence indicated he was 16 years old. Despite this evidence, M.K. had spent four months in an adult prison due to prior rulings. The Supreme Court annulled a lower court decision from the Court of Justice of the Canary Islands that had ordered the young man to be tried as an adult, thereby reasserting the importance of treating minors according to their age, especially in cases involving migrants whose documentation might not be fully verified.
