Questão jurídica principal
Whether the appeal in public law matters was admissible despite the foreigner-law limitation.
Decisão extraída
The appeal was admissible because the appellant invoked a potentially enforceable right under Art. 50 LEtr; whether the conditions were met belonged to the merits.
Fundamentação extraída
Once a possible entitlement under Art. 50 LEtr is asserted, the case is not excluded by Art. 83 let. c ch. 2 LTF at the admissibility stage.
