Questione giuridica chiave
Whether the cantonal court had to admit and inspect the legal opinion of 14 May 2008 as evidence.
Decisione estratta
The court was entitled to refuse the evidence because the document was unrelated to the disputed facts and could not prove any relevant factual element.
Motivazione estratta
The facts were undisputed; the requested statement had been obtained for a different, earlier regulatory process, so no federal-law violation arose from refusing its production.
