Key legal question
Whether the lower court arbitrarily applied cantonal procedural law by treating facts as admitted and later requiring proof of the same facts.
Extracted holding
Yes. After a deemed admission under the default rules, the lower court could not later treat the facts as disputed and reject the claim for lack of substantiation.
Extracted reasoning
The lower court first held that no legally relevant facts remained in dispute after the defendant failed to file a reply, but then relied on later oral objections to impose a proof burden on the claimant. That internal contradiction was incompatible with the default rule deeming factual allegations admitted and therefore arbitrary.
