Questão jurídica principal
Whether the public-law appeal was admissible despite the foreigner clause.
Decisão extraída
The appeal was admissible because the appellant plausibly invoked a right under Art. 50 LEtr; the merits question belonged to the substantive review.
Fundamentação extraída
Where a plausible claim to extension under Art. 50 LEtr exists, Art. 83(c)(2) LTF does not bar federal review.
