Question juridique clé
Whether the subsidiary constitutional complaint against the cantonal decision confirming exequatur and definitive debt enforcement was admissible
Solution extraite
The complaint was inadmissible because the grievances were either not constitutionally framed, insufficiently reasoned, or not exhausted at cantonal level.
Motifs extraits
The Federal Court held that only the subsidiary constitutional complaint was open due to the value threshold. The asserted Lugano Convention and hearing complaints lacked constitutional framing and adequate reasoning; the natural-judge complaint had not been raised below and in any event did not show why Art. 30(2) Cst. would bar exequatur.
