Questione giuridica chiave
Whether the subsidiary constitutional complaint against the cantonal decisions was admissible despite the value threshold and prior cantonal cassation review.
Decisione estratta
A regular civil appeal was unavailable because the dispute value was below the statutory minimum; the complaint was admissible only as a subsidiary constitutional complaint, and only against the cantonal cassation decision as the final cantonal instance for the reviewable objections.
Motivazione estratta
The Obergericht judgment could still have been challenged by cantonal cassation for the alleged procedural and material-law violations, so it was not the last cantonal instance for those grievances.
