Questão jurídica principal
Whether the public law appeal was admissible despite the foreigner law nature of the case.
Decisão extraída
The appeal was admissible under the exception allowing review where a statutory entitlement under Art. 50 LEtr is asserted.
Fundamentação extraída
Although no claim derived from Art. 42 LEtr remained, the alleged entitlement under Art. 50 LEtr raised a reviewable federal-law question; the merits of the three-year requirement belong to the substance, not admissibility.
