Question juridique clé
Whether the cantonal court violated the binding force of the Federal Supreme Court's remand decision under Art. 61 LTF.
Solution extraite
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.
Motifs extraits
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.
