Question juridique clé
Whether the public-law appeal and nullity appeal were admissible against the cantonal revision decision.
Solution extraite
Only the public-law appeal was available; the nullity appeal was inadmissible, and broader relief than annulment was incompatible with the cassatory nature of the remedy.
Motifs extraits
The challenged decision was a final cantonal decision on a revision request based on cantonal procedural law, so only the public-law appeal lay under the Federal Judiciary Act.
