Questão jurídica principal
Whether the cantonal court arbitrarily assessed the landlord's administrator's statement at the site meeting of 10 September 1998.
Decisão extraída
No arbitrary assessment was shown; the court could interpret the phrase 'I could make an effort' as an open statement of financial support, not as an express conditional promise.
Fundamentação extraída
The cantonal court did not ignore the credit arrangement or the sequence of events. Construing the statement differently would concern federal contract interpretation, not arbitrariness.
