Questione giuridica chiave
Whether the appeal met the requirements for challenging factual findings and alleged measurement error.
Decisione estratta
The appellant did not sufficiently substantiate a claim of arbitrariness; the factual challenge was therefore inadmissible.
Motivazione estratta
A factual finding can only be attacked before the Federal Supreme Court for manifest inaccuracy/arbitrariness. The doubt principle has no independent significance beyond arbitrariness review. The submission merely expressed personal conviction of a faulty measurement and did not demonstrate arbitrariness.
