Questione giuridica chiave
Whether the federal complaint sufficiently challenged the cantonal factual findings as arbitrary.
Decisione estratta
No. The complaint did not show, with the required precision, that the cantonal courts had made manifestly incorrect or arbitrary factual findings.
Motivazione estratta
A factual challenge before the Federal Supreme Court requires a precise, substantiated showing of arbitrariness. The appellant did not explain how the cantonal authorities, which could rely on his own statements, had violated this standard.
