Kernrechtsfrage
Whether the intervening party was entitled to a party compensation against the opposing tenant.
Extrahierter Entscheid
Yes, but only exceptionally on grounds of fairness because the intervenor’s participation was necessary for the evidentiary assessment.
Extrahierte Begründung
As a rule, an intervening party does not receive compensation from the opponent. However, where fairness justifies it, a compensation may be awarded. The intervenor here substantially contributed to clarifying the facts and was required to cooperate in evidence production.
