Questão jurídica principal
Whether a construction supervision contract was concluded between the parties and defendant was passively legitimated
Decisão extraída
The alleged contract was not established on appeal review; the cantonal court's factual finding that defendant contracted only with architect B. could not be revisited.
Fundamentação extraída
Contract content and party identity are first determined by subjective interpretation. The appellant merely challenged the weighing of evidence, which is not reviewable on federal appeal absent an allegation of breach of an evidentiary rule.
