Question juridique clé
Whether the appeal under Art. 19 LEF could rely on cantonal law, constitutional, or ECHR violations.
Solution extraite
No; this remedy only allows invocation of federal law, while cantonal, constitutional and ECHR complaints were inadmissible in this procedure.
Motifs extraits
The Federal Court stated that review of cantonal law is excluded and that constitutional and ECHR grievances must be raised by public-law appeal, not under Art. 19 LEF.
