Question juridique clé
Whether the public-law appeal was admissible for complaints about federal law and whether the constitutional grievances were sufficiently reasoned.
Solution extraite
Federal-law complaints could not be raised in the public-law appeal; only properly reasoned constitutional grievances were examined.
Motifs extraits
The public-law appeal is subsidiary and limited to constitutional violations; it does not serve to review federal law. Art. 90 OJ requires specific reasoning.
