Questione giuridica chiave
Whether the federal reform appeal was admissible, including value in dispute and scope of review
Decisione estratta
The appeal was admissible in principle because the dispute value threshold was exceeded; constitutional and cantonal-law complaints were not reviewable in this procedure.
Motivazione estratta
In a reform appeal, only federal law may be invoked. The value in dispute for a lease of indefinite duration is determined by the annual rent and was well above the statutory threshold.
