Key legal question
Whether the cantonal court’s refusal to investigate further was arbitrary or violated the right to be heard.
Extracted holding
No. The court could omit further evidence because it considered any possible landlord fault immaterial once the victim’s grave negligence broke causation.
Extracted reasoning
A refusal to take evidence is permissible when the fact to be proved is irrelevant to the outcome; the cantonal court relied on a causal break caused by the victim’s own conduct.
