Key legal question
Whether the federal appeal could challenge the cantonal fact findings and introduce a new theory of contract estimatory.
Extracted holding
The Court held that new factual allegations and a new contractual theory were inadmissible; the appeal could not attack fact-finding except under the strict federal-law exceptions.
Extracted reasoning
The appellant relied on facts not found by the cantonal court and sought to reargue evidence assessment, which is impermissible in reform proceedings.
