Decisione estratta
The appeal was no longer capable of review and had to be struck off as moot.
Motivazione estratta
Because the cantonal cassation court had set aside the appellate judgment and remitted the case for reconsideration, and that decision was not challenged at the federal level within the statutory period, the federal appeal lost its object.
