Questão jurídica principal
Whether the public law appeal was admissible despite the immigration exclusion clause.
Decisão extraída
A potential right under Art. 49 LEtr could not be excluded at the admissibility stage, so the public law appeal was open.
Fundamentação extraída
For admissibility, a plausible entitlement suffices; Art. 49 LEtr could potentially maintain a right based on Art. 42 LEtr.
