Questione giuridica chiave
Whether the public-law complaint could challenge the cantonal court's factual findings and contract interpretation on fraud and mistake
Decisione estratta
The complaint was admissible only for constitutional review of facts; challenges to the application of federal contract law were not reviewable in this proceeding.
Motivazione estratta
The appellant largely attacked federal law application and made unsubstantiated factual objections; such arguments were inadmissible or failed to meet substantiation requirements.
