Question juridique clé
Whether the federal appeal against the refusal of suspensive effect was admissible
Solution extraite
The appeal was admissible because the interim order was based on cantonal procedural law but closely connected to federal law on precautionary license withdrawal, and irreparable harm was likely.
Motifs extraits
The court held that judicial review of suspensive effect decisions in cantonal remedies against safety withdrawals is allowed under the Federal Judiciary Act framework; the filing was timely and the appellant faced an irreparable disadvantage.
