Kernrechtsfrage
Whether the cantonal court rightly refused to enter into the appeal because no statement of appeal was filed after the announcement.
Extrahierter Entscheid
The refusal to enter into the appeal was lawful because the appellant did not comply with the statutory duty to file a written, reasoned statement of appeal after receiving the reasoned judgment.
Extrahierte Begründung
The appeal instruction was clear: an announcement without reasons was sufficient only to preserve the appeal, but a later written and reasoned statement had to be filed within 20 days. The appellant's contrary reading was not persuasive.
