Questione giuridica chiave
Whether the reform appeal could challenge the cantonal court's factual findings and evidence assessment regarding proof of compensable architectural work.
Decisione estratta
The attack was inadmissible because the Federal Court was bound by the cantonal findings and the appellant did not validly invoke any exception.
Motivazione estratta
In reform proceedings, factual findings are binding except for narrowly defined statutory exceptions; Art. 8 CC does not regulate evidentiary assessment. The appellant merely disputed how the evidence was weighed.
