Question juridique clé
Whether the constitutional complaint met the pleading requirements and whether the cantonal court committed arbitrariness or a hearing violation.
Solution extraite
The complaint was insufficiently reasoned in part and otherwise unfounded; no arbitrariness or denial of hearing was shown.
Motifs extraits
The Court held that only clearly substantiated constitutional claims may be reviewed. The cantonal court's factual assessment was not manifestly untenable, and it could refuse further evidence because the contested points were not materially relevant or would not have changed its view.
