Questione giuridica chiave
Whether the federal appeal was admissible insofar as it relied on facts not found below
Decisione estratta
The appeal was inadmissible to the extent it relied on a factual version not established by the cantonal court, because no properly motivated challenge to the findings was raised.
Motivazione estratta
Under Art. 105 and 106 LTF, factual findings can only be challenged by qualified submissions; the appellants did not meet that standard.
