Question juridique clé
Whether the federal appeal was admissible against the cantonal refusal of legal aid in a driving-licence matter
Solution extraite
The appeal was admissible in principle because the underlying measure concerned preventive withdrawal of a driving licence in a public-law matter.
Motifs extraits
An appeal in public law lies against final cantonal decisions on administrative driving-licence measures, including preventive withdrawal; the same remedy is available against a refusal of legal aid in that context.
