Questão jurídica principal
Whether the alleged extension agreement for the period after 1998-10-31 could be reviewed on appeal
Decisão extraída
The appeal could not challenge the cantonal court's refusal to find an extension agreement, because this was an evidentiary assessment not reviewable in the ordinary federal appeal.
Fundamentação extraída
The appellant's arguments attacked the binding factual findings of the lower court; those findings are not subject to federal review in the appeal, absent exceptional circumstances.
