Questão jurídica principal
Whether the reform appeal was admissible despite the appellant's criticism of fact-finding and proof assessment.
Decisão extraída
The appeal could not challenge the cantonal court's factual findings or evidence assessment, and the appellant relied on facts outside the binding record.
Fundamentação extraída
A reform appeal lies only for federal-law violations; it does not permit attacks on constitutional issues, cantonal procedural law, or evidence appraisal absent a recognized exception.
