Questione giuridica chiave
Whether the cantonal decision remitting the case for investigation was immediately appealable before the Federal Tribunal.
Decisione estratta
The decision was an incidental ruling and was not immediately appealable because neither irreparable legal harm nor the exception for avoiding lengthy and costly evidence was shown.
Motivazione estratta
A remittal order to open an investigation does not normally cause irreparable legal prejudice; any harm relied on by the appellants stemmed only from possible use of the decision in foreign proceedings. The prospective investigation was not shown to be unusually long or costly.
