Question juridique clé
Whether the appeal against the refusal of legal aid and interim cost-advance order was admissible
Solution extraite
Yes. The order caused irreparable harm and the residence-permit revocation appeal remained, in principle, reviewable despite being an appeal against a withdrawal of an existing C permit.
Motifs extraits
A refusal of legal aid combined with a requirement to pay an advance is independently challengeable. For a C permit, the unity-of-proceedings rule does not bar federal review because the permit would otherwise continue to have legal effect.
