Questione giuridica chiave
Whether the federal appeal met the statutory reasoning requirements under Art. 42 BGG
Decisione estratta
The appeal did not satisfy the mandatory reasoning requirements because it did not engage with the decisive grounds of the cantonal judgment in a concrete and sufficiently substantiated manner.
Motivazione estratta
A valid appeal must state requests and reasons and explain, in concise form, which legal errors are alleged. The appellant's single substantive complaint about an expert report did not show any violation of federal law or manifestly incorrect fact-finding.
