Questione giuridica chiave
Whether the appeal against the cantonal judgment was admissible insofar as it challenged the lower authorities' decisions rather than the Obergericht's ruling.
Decisione estratta
The appeal was inadmissible to that extent because only the final cantonal decision could be challenged.
Motivazione estratta
Art. 75(1) BGG limits the appeal to final cantonal decisions; earlier decisions were therefore not open to direct challenge.
