Key legal question
Whether the federal appeal was admissible despite challenging only part of the cantonal decision's independent grounds.
Extracted holding
No. The appeal did not address all independent and sufficient reasons supporting the cantonal judgment, so the Federal Supreme Court could not enter into the merits.
Extracted reasoning
When a decision rests on several independent grounds, the appellant must show that each ground violates federal law; challenging only the formal objections left an alternative substantive ground untouched.
