Key legal question
Whether the hall collapse caused by snow load constituted an insured elemental loss under the building insurance rules.
Extracted holding
The collapse was not shown to result from an extraordinary natural event; the snow load did not exceed the hall's norm-bearing capacity under the applicable SIA standard.
Extracted reasoning
An insured snow-loss event requires an extraordinary and sudden natural force. The insured had the burden to prove such an elemental event. The evidence, especially the expert opinion and weather data, showed no extraordinary snowfall or snow load on the collapse date; the norm load was not exceeded.
