Questione giuridica chiave
Whether the appellant had standing to appeal the refusal to admit him as a private plaintiff.
Decisione estratta
He did not demonstrate that the refusal could affect his civil claims, so he lacked appeal standing on that point.
Motivazione estratta
Although the decision was final for the exclusion issue and the appellant participated in the proceedings, private-plaintiff standing before the Federal Supreme Court also requires an effect on civil claims. The appellant did not substantiate this, and the lower court had expressly excluded any civil claim impact.
