Questione giuridica chiave
Whether new documents filed for the first time before the Federal Supreme Court were admissible.
Decisione estratta
They were inadmissible novelties because the residence issue had already been contested in the cantonal proceedings.
Motivazione estratta
Under Art. 99(1) BGG, new facts and evidence are allowed only if the cantonal judgment gave rise to them; that was not the case here.
