Kernrechtsfrage
Whether the Federal Supreme Court could review the cantonal decision on a possessory action only for constitutional violations.
Extrahierter Entscheid
Yes; possessory actions are treated as interim measures, so review was limited to constitutional rights.
Extrahierte Begründung
The court held that possessory actions merely restore or maintain the prior factual situation and are therefore provisional for purposes of Art. 98 LTF.
