Questione giuridica chiave
Whether the federal appeal against the 28 September 2007 cantonal judgment was filed in time.
Decisione estratta
No. The interpretation request did not extend the federal appeal deadline under Art. 100(6) LTF.
Motivazione estratta
A request for interpretation is not an appeal to another judicial authority; therefore the special rule of Art. 100(6) LTF does not apply. The deadline had already expired.
