Questão jurídica principal
Whether the respondents' renovation works established an adequate causal link to the alleged damage in the appellant's leased apartment under Arts. 679 and 684 CC.
Decisão extraída
The Federal Supreme Court held that the canton court could deny adequate causation on the basis of its factual findings and expert evidence; the appeal did not establish a violation of federal law.
Fundamentação extraída
Adequate causation is a legal concept, but the canton court's assessment relied on factual findings that the plaster ceiling and insulation in the leased apartment should have retained the debris, and that the actual fall was attributable to a slight defect in the ceiling above the wardrobes, not to the works themselves. Arguments attacking this appraisal of evidence were inadmissible in reform appeal.
