Questão jurídica principal
Whether refusal to obtain all interrogation transcripts violated the right to be heard or was arbitrary.
Decisão extraída
No violation was shown; the appellate court could rely on the existing file and anticipate that further evidence would not change the result.
Fundamentação extraída
The court held that only clearly substantiated constitutional complaints are reviewable. The requested evidence concerned no decisive fact, and the defendant's own statements plus other participants' statements already supported the finding that he had a leadership role.
