Kernrechtsfrage
Whether the request to top the birch tree was admissible after the remand judgment.
Extrahierter Entscheid
The birch-tree claim was no longer open on remand and therefore could not be reviewed again.
Extrahierte Begründung
The Federal Supreme Court had already definitively resolved that point in the remand judgment; the cantonal court and the parties were bound by the remand scope.
