Questão jurídica principal
Whether the criminal complaint could be heard despite the appellant's lack of substantiated civil-claim standing.
Decisão extraída
The appellant failed to show, or make plausible, how the challenged decision could affect any civil claim arising from the alleged defamation; the appeal was therefore not admissible.
Fundamentação extraída
A private complainant may appeal in criminal matters only if the decision can affect civil claims. Where this is not obvious, the appellant must explain the possible impact. He did not do so here.
