Kernrechtsfrage
Whether the appellant could challenge the cantonal courts' factual findings on lease continuation and absence of a transfer of tenancy.
Extrahierter Entscheid
The Supreme Court would not review the challenged facts because the appellant had not exhausted the available cantonal extraordinary remedy for alleged factual errors and did not satisfy the strict substantiation requirements.
Extrahierte Begründung
Findings of the lower courts are binding under the federal procedural rules unless properly and specifically attacked; the appellant's criticism was insufficient and relied on issues that should have been raised by cantonal nullity appeal.
