Kernrechtsfrage
Whether Y. AG could be admitted into the proceedings despite not being a party below.
Extrahierter Entscheid
Yes. As no party objected, the Court treated this as consent to a party change and admitted Y. AG to the proceedings.
Extrahierte Begründung
The transfer of the property to Y. AG and the absence of objections justified assuming consent to substitution under the applicable procedural rules.
