Solution extraite
The complaint was inadmissible because the arbitrariness argument had not been raised in the cantonal appeal instance; in any event, the challenged assessment was not arbitrary.
Motifs extraits
A constitutional complaint for arbitrariness requires exhaustion of the cantonal instance chain in substance. The court also noted that the legal assessment of the expert findings belongs to the judge.
