Questão jurídica principal
Whether the constitutional complaint sufficiently substantiated arbitrariness in the cantonal court's assessment of natural causation.
Decisão extraída
The complaint did not meet the strict substantiation requirements for a constitutional complaint against a cassation decision.
Fundamentação extraída
The appellants merely presented their own version of the facts and did not confront the cassation court's reasoning showing that the landslide was caused by exceptional rainfall, not by the pipe rupture. Arguments directed only against the appellate judgment or raised for the first time were inadmissible.
