Questione giuridica chiave
Whether the Federal Court could revisit arguments already decided in the prior remand judgment
Decisione estratta
The Court would not enter on arguments already binding from the earlier remand, including the hearing complaint and the complaint about splitting costs among the three investigations.
Motivazione estratta
A remand decision binds both the cantonal authority and the Federal Court on the legal reasoning that justified the remand; repeated arguments are therefore precluded.
