Overview
- Relator Alexandre de Moraes set a two‑day public hearing on 24 and 25 August to discuss four consolidated direct actions that challenge the constitutionality of the Marco Legal do Combate ao Crime Organizado.
- The hearing will be held in the STF plenary and invitations were sent to the other justices and to the attorney‑general so the court can hear state and institutional views.
- Civil‑society groups and experts may register to speak until 10 August and the court will publish the list of selected participants on 17 August using criteria of representativeness, technical qualification and plurality of views.
- The challenges target specific provisions of the law, including new criminal definitions and higher penalties for gang leaders, bans on conditional release, a presumption favoring preventive detention, asset forfeiture without final conviction, corporate precautionary measures, monitoring of lawyer‑prisoner meetings, cancellation of voter registration for certain detainees, and preferred videoconference custody hearings.
- Sanctioned by President Lula earlier in 2026 as a flagship crime‑fighting measure, the law’s fate could change how courts use preventive detention, how companies and lawyers are treated in criminal probes, and how enforcement and electoral rules operate in practice.
