Questione giuridica chiave
Whether the nullity complaint could challenge the factual findings under Art. 277 BStP.
Decisione estratta
The complaint was inadmissible insofar as it attacked binding factual findings rather than properly alleging federal-law violations.
Motivazione estratta
Art. 277 BStP is not an independent ground of complaint; it requires a properly framed allegation under Art. 273(1)(b) BStP. The defendant instead contested facts that the Federal Court could not review in nullity proceedings.
