Background
Luan da Silva Martimiano was convicted in the state courts of Minas Gerais of aggravated robbery under Article 157, § 2º, II of the Brazilian Penal Code and sentenced to seven years of imprisonment in a closed initial regime. The Minas Gerais Court of Justice (TJMG) upheld the conviction on appeal. The defense then filed a habeas corpus petition with the Superior Tribunal de Justiça (STJ), arguing two grounds: first, that evidence obtained through an irregular warrantless home entry was tainted and should be excluded; and second, that the evidence of authorship was insufficient because the victim never identified Martimiano as a perpetrator, the co-defendant’s out-of-court accusation was later recanted and never confirmed before a judge, and the police testimony linking him to the crime was entirely hearsay.
The STJ’s reporting justice declined to admit the habeas corpus on formal grounds — the writ is not a substitute for ordinary appellate review — but nonetheless granted relief sua sponte (de ofício), acquitting Martimiano under Article 386, VII of the Code of Criminal Procedure (CPP), which requires acquittal when the evidence is insufficient to support a conviction. This ruling was made in agreement with the opinion of the Federal Public Ministry (MPF). The Minas Gerais state prosecutor’s office (MPMG) then filed an internal interlocutory appeal (agravo regimental) challenging that acquittal, arguing the court had improperly re-examined the factual record in violation of the cognitive limits of habeas corpus proceedings, and asking that the original conviction be reinstated.
The Court’s Holding
The Fifth Panel unanimously denied the agravo regimental, affirming the acquittal. The court held that a sua sponte habeas corpus order is permissible — even when the writ is not formally admitted — to correct a manifest illegality, and that doing so does not constitute impermissible fact-finding when the record, taken on the lower courts’ own factual findings, reveals a complete absence of minimally consistent and independent evidence of authorship. The court was careful to distinguish between re-weighing contested evidence (which habeas corpus cannot do) and recognizing that the evidence, accepted at face value, simply does not reach the constitutional threshold required for conviction.
On the merits, the court catalogued each piece of evidence and found it wanting. The victim identified the crime’s occurrence but never identified Martimiano as a perpetrator; photo identification was conducted only with respect to the co-defendant. Police testimony attributing co-authorship to Martimiano was indirect — the officers relayed what the co-defendant had told them, without any direct perception of Martimiano’s participation — and therefore lacked independent probative value. The co-defendant’s extrajudicial accusation was subsequently recanted and never confirmed under cross-examination in court, rendering it an uncontested inquisitorial element that cannot support a conviction. Vehicle tracking data and statements by family members amounted, at most, to peripheral circumstantial indicators insufficient to individualize guilt beyond a reasonable doubt.
The court formalized three binding propositions: (1) a sua sponte habeas corpus order is available to remedy a manifest illegality when there is no minimally adequate and independent basis for finding authorship, without constituting impermissible factual re-examination; (2) a non-existent victim identification, a recanted extrajudicial co-defendant statement unconfirmed at trial, indirect police testimony, and peripheral circumstantial indicators together do not individualize authorship or sustain a conviction; and (3) in the absence of sufficient proof of authorship, acquittal must be entered under CPP Article 386, VII.
Key Takeaways
- A Brazilian habeas corpus court may acquit a defendant sua sponte — even without formally admitting the writ — when the record reveals a manifest illegality in the form of a total absence of minimally reliable evidence of authorship, provided the court does not engage in subjective re-weighing of disputed facts.
- A recanted, extrajudicial co-defendant statement that was never subjected to adversarial cross-examination in court cannot, standing alone or in combination with indirect hearsay police testimony, sustain a criminal conviction; the right to confrontation (contraditório) requires that inculpatory statements be tested in court before they carry convicting weight.
- The absence of a victim identification of the accused — as opposed to identification of a co-defendant — is a decisive gap: evidence that establishes the crime occurred does not by itself establish who committed it, and that individualization gap cannot be filled by peripheral indicia such as vehicle tracking or family informant statements.
- CPP Article 386, VII (acquittal for insufficiency of evidence) applies not only when no evidence exists but also when the evidence that does exist, assessed against the reasonable-doubt standard, is too fragmented and uncorroborated to support a finding of guilt.
Why It Matters
This decision reinforces strict limits on what combinations of evidence can constitutionally anchor a criminal conviction in Brazil. By methodically dissecting each piece of the prosecution’s case — absent victim ID, recanted and untested co-defendant accusation, hearsay police testimony, and peripheral circumstantial data — and finding each category independently and collectively insufficient, the STJ sends a clear signal to trial courts that fragmentary, mutually dependent evidence does not become adequate merely through accumulation. Defense counsel in pending cases with similar evidentiary profiles can point to the court’s formal teses as grounds for acquittal or habeas relief.
The ruling also clarifies the procedural boundary between permissible habeas corpus sua sponte intervention and impermissible factual review. The STJ draws the line at whether the court is re-evaluating the weight of evidence (forbidden) versus recognizing, on the lower court’s own factual premises, that a legal minimum of proof was never reached (permitted). This distinction has practical significance for litigants and lower courts navigating Brazil’s layered post-conviction review system, particularly in cases where ordinary appellate remedies have been exhausted.
