Kernrechtsfrage
Whether refusing to take evidence on comparable neighborhood rents violated the right to be heard.
Extrahierter Entscheid
No. The landlords had not clearly and timely offered such evidence, and the issue was not properly introduced in the written exchange.
Extrahierte Begründung
Under the written procedure, the parties had to state their means in the first brief. The landlords did not raise neighborhood rents then, so the court could limit evidence to the issues actually joined.
