Question juridique clé
Whether the complaint met the Federal Supreme Court's substantiation requirements and could be examined on the merits.
Solution extraite
It did not. The allegation of possible contamination was unsubstantiated and failed to show any legal error or arbitrariness in the cantonal assessment.
Motifs extraits
The appellant merely repeated an unsupported contamination theory. That was insufficient under the strict reasoning requirements for alleging violations of federal law or arbitrariness.
