Question juridique clé
Whether the cantonal court sufficiently justified the architect’s fee award under Art. 394 para. 3 CO.
Solution extraite
No. The reasons given did not allow federal review of how the remuneration was calculated or why the chosen method was preferable.
Motifs extraits
The court could not verify the use of SIA Rule 102/2003 or the fee calculation because the judgment lacked the necessary factual and legal explanation; the assessment under Art. 394 para. 3 CO is a legal question for the judge, not something that can be delegated entirely to the expert.
