Questão jurídica principal
Whether the public-law appeal was admissible to challenge the refusal to prosecute for false testimony.
Decisão extraída
The appeal was inadmissible insofar as it attacked the criminal-law merits, because the complainants lacked standing to contest the refusal to prosecute.
Fundamentação extraída
A complainant without victim status under the LAV generally cannot challenge a decision declining prosecution; only formal denial of justice claims are open, not merits review.
