Questione giuridica chiave
Whether the federal appeal was admissible against the cantonal appellate decision when it also criticized the first-instance judgment.
Decisione estratta
The appeal was inadmissible insofar as it challenged the first-instance decision, because the federal appeal may only be directed against the challenged appellate decision.
Motivazione estratta
The appellant did not meet the requirements to show which rights were violated by the appellate court; federal constitutional claims are reviewed only if expressly raised and reasoned. The submission of 7 December 2012 did not satisfy Art. 42 and 106 BGG.
