Questão jurídica principal
Whether the complaint in public law matters was admissible despite the immigration context and the asserted permit claim.
Decisão extraída
The complaint was admissible because the appellant plausibly invoked a possible entitlement based on the FZA and Art. 50 AuG.
Fundamentação extraída
A potential right suffices for standing; the Court could review the revocation because the permit continued to have legal effects.
