Questione giuridica chiave
Whether the landlord proved an admissible local and quarter customary rent through comparable objects.
Decisione estratta
The landlord failed to prove the objection because he could not provide at least five sufficiently comparable apartments in the same quarter or an acceptable exception.
Motivazione estratta
Comparable objects in Zufikon were excluded because they were in another quarter and separated by the Reuss and another district; the three objects in Bremgarten Ost were also in a different quarter from the tenants' apartment, and no reason for an exception was shown.
