Questione giuridica chiave
Whether the husband could challenge the principle of imputing a hypothetical income after the remand judgment.
Decisione estratta
He could not; the issue had already been definitively decided in the earlier appellate proceedings and was no longer open.
Motivazione estratta
The Federal Court held that the remand was limited to recalculating the amount of the hypothetical income, not to revisiting its principle. The cantonal court and the parties were bound by the prior remand ruling and by the earlier unchallenged factual findings.
