Background

Paulo Ricardo Barbosa da Silva was convicted of drug trafficking and his conviction became final (trânsito em julgado). He subsequently filed a habeas corpus petition with the Superior Tribunal de Justiça (STJ) seeking re-sentencing on the grounds that the sentencing calculation (dosimetria) imposed on him was improper. The President of the STJ summarily denied the writ at the threshold stage, holding that habeas corpus is not an admissible vehicle for challenging a final, unappealable conviction.

The petitioner then filed an interlocutory appeal (agravo regimental) against that summary denial, asking either that the presiding justice reconsider the individual ruling or, alternatively, that the matter be referred to the full Sixth Panel for collegial review and the habeas corpus order be granted.

The Court’s Holding

The Sixth Panel, voting unanimously, declined to hear the agravo regimental. The court found that the petitioner had done no more than repeat the arguments already raised in the original habeas corpus petition — namely, that his sentence should be recalculated — without addressing, much less refuting, the core rationale for the summary denial: that habeas corpus cannot be used to collaterally attack a conviction that has already passed into finality.

Because the petitioner failed to specifically challenge the dispositive ground of the lower ruling, STJ Precedent No. 182 (Súmula 182/STJ) applied. That rule bars consideration of an internal appeal whose arguments merely restate those of the underlying petition without engaging the actual basis on which relief was refused. Accordingly, the Panel did not reach the merits of the sentencing claim.

Key Takeaways

  • Habeas corpus at the STJ is not available as a mechanism to revisit or re-sentence a defendant whose conviction has become final — this procedural bar is a threshold issue that will defeat the writ without merits review.
  • An agravo regimental challenging a summary denial must directly rebut the specific ground on which that denial rested; merely restating the original petition’s arguments is insufficient and triggers dismissal under Súmula 182/STJ.
  • The decision was unanimous among all five members of the Sixth Panel, underscoring the settled nature of both procedural rules applied.

Why It Matters

This ruling reinforces the STJ’s consistent position that habeas corpus is an extraordinary remedy with defined constitutional boundaries, and that it may not be repurposed as a surrogate for post-conviction sentencing review once a judgment is final. Defense counsel seeking to challenge a definitive conviction must instead pursue the proper procedural avenue — typically a revisão criminal (criminal review action) before the competent court — rather than habeas corpus.

The application of Súmula 182/STJ also serves as a practical reminder that internal appeals in the superior courts carry a heightened pleading requirement: counsel must identify and directly answer the decisional rationale of the ruling being challenged, or risk dismissal on procedural grounds alone, foreclosing any substantive review of the underlying claim.
