Question juridique clé
Whether the public-law appeal was admissible despite the availability of a federal appeal on the same complaint.
Solution extraite
No. Because the value in dispute exceeded the statutory threshold and a federal appeal was open, the extraordinary public-law appeal was excluded.
Motifs extraits
The complaint concerned alleged misapplication of federal law, not a constitutional review unavailable by federal appeal. Since another federal remedy existed, Art. 84 al. 2 OJ barred the public-law appeal.
