Questione giuridica chiave
Whether the appeal still had an current practical interest after the appellant had been transferred to Italy
Decisione estratta
The appeal lacked a current practical interest because the appellant had already been returned to the responsible Dublin state; no exception to the mootness requirement applied.
Motivazione estratta
Under Art. 89 BGG, standing requires an actual, practical interest both when filing and at judgment. Since that interest disappeared during the federal proceedings, the case had to be struck as moot.
