Question juridique clé
Whether the appellate court arbitrarily applied cantonal costs rules by refusing to find unnecessary prolixity by the respondent and by charging the appellant all costs.
Solution extraite
The appellate court could reasonably conclude that the respondent had not caused unnecessary prolixity; its cost allocation was not arbitrary.
Motifs extraits
A defendant may rely on several alternative arguments, even if inconsistent. The evidentiary hearing was needed because no receipt proved payment, so the respondent's denial of payment did not itself amount to unnecessary prolixity.
