Questione giuridica chiave
Whether the cantonal court violated the binding force of the Federal Supreme Court's remand decision under Art. 61 LTF.
Decisione estratta
No. The remand decision had left open whether the balcony side nonetheless constituted an opening, so the cantonal court could decide that issue on new grounds.
Motivazione estratta
A remand binds the lower court only on matters actually decided. Issues expressly left unresolved may be decided anew on the factual basis reserved by the Supreme Court.
