Decisione estratta
No, the file did not establish a natural causal connection with the required degree of probability.
Motivazione estratta
The cantonal court had carefully assessed the records and reasonably concluded that the necessary probability threshold was not met; the objections raised on appeal did not undermine that assessment.
