Key legal question
Whether the public law appeal could succeed despite attacking only one of two independent grounds for inadmissibility.
Extracted holding
No. Because the cantonal judgment rested on two independent sufficient reasons, the appellant had to challenge both; the unchallenged main reason made the federal appeal inadmissible.
Extracted reasoning
Under settled federal case law, each independent and sufficient ground of a decision must be attacked with the proper remedy. The appellant directed his criticisms only against the subsidiary reasoning and left the main procedural ground untouched.
