Questione giuridica chiave
Whether the appeal could still challenge provisions already declared invalid below (3b and 3c first and second lemmas).
Decisione estratta
No. The appellant lacked a legally protected interest because those provisions had already been annulled by the cantonal appeal court.
Motivazione estratta
A party cannot appeal a point on which it has already obtained complete relief; the appeal was therefore inadmissible to that extent.
