Questão jurídica principal
Whether the case had to be remanded for additional factual findings under Art. 64 OG.
Decisão extraída
No remand was required because the cantonal court had already established all facts relevant to the decision.
Fundamentação extraída
The requested clarification would not add legally relevant facts; the appeal court had found that the parties agreed on a work-value fee and that the monthly statements were sent to obtain payment, not for job verification.
