Key legal question
Whether the appeal could rely on alleged violations of Art. 6 ECHR, cantonal procedural law, and cost awards.
Extracted holding
The ECHR complaint was inadmissible in appeal; cantonal-law and cost objections were not cognizable in this appeal.
Extracted reasoning
The court held that only federal law and international treaties may be raised by appeal, while constitutional and cantonal-law complaints are reserved to other remedies; objections to cantonal procedure and to costs based on cantonal law therefore fell outside appellate review.
