Questão jurídica principal
Whether the civil appeal was admissible despite the appellant's challenge to the factual findings.
Decisão extraída
The appeal could not be entertained because the appellant attacked the facts without showing, in a substantiated manner, that the findings were manifestly incorrect or based on legal error.
Fundamentação extraída
Under Art. 105(1) and Art. 97(1) BGG, factual findings may only be challenged on narrow grounds. Mere counterstatements or reference to canton-level submissions are insufficient; the appellant did not meet this burden.
