Background
Hernando Martinez Monroy was convicted of theft (furto) under Article 155 of the Brazilian Penal Code for stealing a bottle of Johnnie Walker Blonde whisky valued at R$ 119.90 (approximately USD 24) from a supermarket on November 15, 2023. He was apprehended at a nearby bus station still in possession of the merchandise after being pursued by the store’s loss-prevention coordinator. He confessed in court, and both the material act and authorship of the crime were established through the arrest report and witness testimony.
Monroy filed a habeas corpus petition arguing that his conviction should be overturned based on the principle of insignificance (princípio da insignificância) — a doctrine that permits courts to decline to punish conduct that causes minimal harm and warrants reduced reprehensibility. His argument emphasized that the item’s value fell below ten percent of Brazil’s minimum wage and that he had returned the property. He also had six prior annotations on his criminal record (FAC), all for property crimes of the same nature, with two final convictions. The trial court rejected the insignificance defense, and Monroy appealed to the Superior Tribunal de Justiça (STJ) via habeas corpus and, subsidiarily, requested an open-regime sentence or conversion of his custodial sentence to alternative sanctions.
The Court’s Holding
The STJ, sitting in the Sixth Panel, unanimously denied the habeas corpus petition. The court held that habeas corpus cannot be used as a substitute for proper appeals to overturn a conviction unless the petitioner demonstrates manifest illegality or abuse of power — neither of which was present here. The court reaffirmed the inadequacy of the remedy for this procedural context.
On the merits, the court held that the principle of insignificance does not apply when a defendant exhibits habitual criminality (habitualidade delitiva). The court emphasized that the principle requires four cumulative conditions, established by Brazil’s Supreme Federal Court: minimal offensiveness of the conduct, absence of social danger, reduced degree of reprehavability of the agent’s behavior, and inexpressiveness of the legal injury caused. Here, Monroy’s multiple prior convictions for property crimes of the same nature demonstrated unfavorable personal conditions and a high degree of reprehavability that precluded application of the doctrine. The court stated that “the small value of the stolen property and the return of the item, considered in isolation, are not sufficient to characterize the lack of material typicality of the conduct when there is repeated practice of property crimes.”
The court also noted that the nature of the stolen item — an alcoholic beverage not essential for subsistence — further weighed against applying the principle. The court rejected the subsidiary requests for sentencing modifications as procedural innovation (inovação recursal), since these arguments had not been raised in the original habeas corpus petition, which sought only absolution via the insignificance principle.
Key Takeaways
- Habeas corpus cannot serve as a substitute appeal mechanism to overturn convictions absent manifest illegality or abuse of power.
- The principle of insignificance does not apply to repeat property offenders, even when the stolen item is de minimis in value and is returned to the victim.
- Habitual criminality (multiple prior convictions for property crimes) is an obstacle sufficient to preclude application of the insignificance doctrine, regardless of isolated facts favoring leniency.
- Subsidiary arguments not raised in the original petition cannot be introduced on appeal without constituting procedural innovation barring review.
Why It Matters
This decision provides clear guidance on the limits of Brazil’s principle of insignificance in criminal law. While the doctrine permits courts to disregard de minimis harms in appropriate cases, the STJ confirms that repeat property offenders cannot exploit the principle’s leniency to evade conviction for theft, regardless of the item’s trivial value or subsequent return. The holding discourages career property criminals from committing numerous small thefts in the hope of obtaining absolution through insignificance arguments.
The decision also reinforces strict procedural requirements for habeas corpus and the doctrine of inovação recursal, preventing litigants from using appellate proceedings to raise new arguments not ventilated in the original petition. This maintains procedural regularity and ensures that trial courts have fair notice of all defenses being asserted.
