Questão jurídica principal
Whether the civil appeal was admissible despite a subsidiary, independently sufficient reasoning left unchallenged.
Decisão extraída
The appeal was inadmissible because the appellant did not contest all independent reasons supporting the cantonal judgment.
Fundamentação extraída
When a decision rests on multiple independent grounds, each must be attacked; the appellant failed to challenge one subsidiary ground showing he could not have succeeded even absent any lawyer fault.
