Questione giuridica chiave
Whether the federal appeal introduced inadmissible new claims by challenging Art. 7a QPB
Decisione estratta
The appeal remained admissible because the dispute before the Federal Supreme Court was limited to the compensation rule in Art. 7a QPB, and the respondent had withdrawn his own appeal.
Motivazione estratta
The appellant did not expand the dispute; it sought review of the remaining compensation obligation. Any broader challenge would have required the respondent to contest the later revised quarter plan, which he did not do.
