Question juridique clé
Whether the public-law appeal was admissible despite the availability of a reform appeal

The appeal was inadmissible because the alleged violation could have been raised by reform appeal.
Motifs extraits
The challenged cantonal decision concerned a civil monetary dispute and, in substance, a federal civil-law res judicata question; the reform appeal was therefore the proper remedy under Art. 84(2) OJ.
