Kernrechtsfrage
Whether the tenants' appeal satisfied the formal requirement of a substantive request.
Extrahierter Entscheid
A bare remand request was at least doubtful as a sufficient remedy request, but the court left the point open because the appeal failed on the merits.
Extrahierte Begründung
A remand request is sufficient only if the Federal Supreme Court could not decide the case itself. Here, the appellants did not show any necessary supplementation of the facts.
