Question juridique clé
Whether the constitutional complaint was sufficiently substantiated to permit review of alleged arbitrariness and procedural nullity.
Solution extraite
The complaint did not meet the required substantiation standard; the Federal Court therefore could not examine the arbitrariness allegations.
Motifs extraits
The appellants merely restated their view of the law and labeled the cantonal decision arbitrary without showing concretely why it suffered from a manifest defect. A purportedly fictitious recusal proceeding could in any event not amount to the kind of nullity relevant in definitive debt enforcement.
