Background
Jessica da Silva Bastos was arrested in flagrante delicto on December 28, 2025, charged with negligent homicide while driving a motor vehicle. Her arrest was converted to preventive detention. Bastos filed for habeas corpus at the state appellate court (Tribunal de Justiça), seeking either alternative precautionary measures under Article 319 of the Criminal Procedure Code or house arrest given her status as the mother of minor children under age 12. The duty judge denied the preliminary injunction.
Bastos then filed an interlocutory appeal (agravo regimental) before the Superior Tribunal de Justiça, arguing that the preventive detention lacked concrete and individualized justification. She contended that the decision relied only on generic references to the gravity of the offense without demonstrating a specific current risk to public order, criminal proceedings, or application of penal law. She requested either reconsideration or collective panel review of her case.
The Court’s Holding
The Fifth Panel unanimously denied the appeal. The court held that STF Súmula 691—which provides that “it is not within the competence of the Supreme Federal Court to know of habeas corpus filed against a decision by a Relator that, in a habeas corpus requested to a superior court, denies the preliminary injunction”—bars review of the trial judge’s denial of preliminary relief, except in cases of flagrant illegality or manifest absurdity. The panel found no such illegality here.
The court emphasized that the lower court judge had not identified any flagrant illegal constraint warranting preliminary relief. No factual or legal circumstances demonstrated teratological error or evident illegality sufficient to set aside the procedural bar. The panel stressed that allowing habeas corpus in these circumstances would improperly “suppress an instance” (suppress the state court’s authority) and bypass the appellate court’s responsibility to fully review preventive detention decisions. Because Bastos presented no new arguments capable of altering the trial court’s position, the court maintained the lower decision on its original legal grounds.
Key Takeaways
- STF Súmula 691 creates a procedural barrier against habeas corpus challenging decisions denying preliminary injunctions in prior habeas corpus filings, and this barrier applies unless flagrant illegality or absurdity is demonstrated.
- A preventive detention order based on generic language regarding the gravity of the offense does not constitute flagrant illegality sufficient to overcome this procedural bar when the initial habeas corpus petition has already received trial court review.
- Interlocutory appeals must present genuinely new arguments or novel legal theories; mere re-litigation of previously considered grounds does not warrant reversal.
- The doctrine of “instance suppression” prevents higher courts from bypassing lower courts’ authority to fully adjudicate habeas corpus petitions and preserve the structured appellate hierarchy.
Why It Matters
This decision reinforces that habeas corpus petitions challenging preventive detention must first be exhausted at the trial court level without improper escalation to higher courts. Practitioners seeking appellate review of denied preliminary relief in habeas corpus cases must identify flagrant illegality or procedural absurdity, not merely express disagreement with the trial judge’s discretionary judgment. The decision clarifies that generic invocations of crime severity in preventive detention orders—without articulation of specific identified risks—do not automatically constitute the category of illegality allowing a second habeas corpus petition to bypass Súmula 691’s procedural bar.
The ruling protects state appellate courts’ authority to review and remedy preventive detention decisions before the federal Superior Tribunal de Justiça intervenes, maintaining Brazil’s structured appellate system and deterring forum-shopping through repetitive habeas corpus filings that would circumvent proper procedural channels.
