Filing or Notice? Brazil’s Superior Court of Justice Draws the Line on When an Arbitral Award Is ‘Presented’ Within the Meaning of the Brazilian Arbitration Act

On 8 April 2026, Brazil's Superior Court of Justice (Superior Tribunal de Justiça, "STJ") decided REsp No. 2,210,332/SC, a case that required it to answer a deceptively simple question: when, precisely, is an arbitral award 'presented' for purposes of the time limit imposed on arbitrators under the Brazilian Arbitration Act (Law No. 9,307/1996, 'BAA')?

The point requires some clarification in English. “Presentation” is used here as a translation of the Portuguese statutory term ‘apresentação’. It does not refer to an oral presentation, nor does it necessarily mean formal notice or service of the award on the parties. The question before the STJ was whether apresentação, for purposes of Article 12(III), occurs when the award is signed, when it is filed or made available in the arbitration record, or only when the parties are formally notified of it.

The BAA's time-limit regime works in two stages. First, parties may agree on a deadline for issuance of the award (Article 11(III)). Absent party agreement, the default is six months, counting from the constitution of the arbitral tribunal (Article 23). Second, if that deadline lapses without an award being issued, the arbitral mandate is not automatically extinguished. In arbitrations initiated through a submission agreement (compromisso arbitral), rather than through an arbitration clause, the interested party must actively notify the sole arbitrator, or the presiding arbitrator in the case of an arbitral tribunal, and grant a further ten days for the issuance and presentation (prolação e apresentação) of the award (Article 12(III)). Only after that cure period expires does Article 32(VII) authorize an annulment action on the ground of delay.

A separate provision governs notice of the award to the parties. Article 33, §1 requires an annulment action to be brought within ninety days from 'notification' (notificação) of the award. Article 29 also contemplates that the arbitrator must send a copy to the parties with proof of receipt.

These three concepts: (i) ‘issuance’ or rendering of the award; (ii) 'presentation', in the sense of filing or making the award available in the arbitration record; and (iii) 'notification' or formal communication to the parties, sit at the heart of the dispute put before the STJ and, as this post argues, their precise relationship remains an open question despite the ruling.

I. The Case: A Four-Day Gap and a Three-Way Interpretative Dispute

The facts of the case are straightforward. The arbitration was commenced pursuant to a submission agreement, since the arbitration clause in the contract was incomplete. The parties agreed that a sole arbitrator would render an award within 180 days from the date of the parties’ final submission. When that period elapsed without a decision, Dell'Pradi Imóveis Ltda (the Claimant) notified the arbitrator on 5 March 2015, triggering the ten-day cure period under Article 12(III). The award was signed on 12 March and filed in the arbitration record on 13 March 2015; both signing and filing happened within the ten-day window. The parties, however, were only formally notified of the award four days later, on 17 March 2015.

Dell'Pradi brought an annulment action arguing that 'presentation' occurred only on 17 March, when the parties were formally notified, such that the award was made out of time for two working days. The first-instance court ruled in favor of Dell’Pradi and annulled the award. On appeal, the Court of Appeal of Santa Catarina ("TJSC") reversed the first instance ruling, reasoning that formal notification is merely the act by which parties are informed of something already in the record.

Dell'Pradi then appealed to the STJ, making an argument that went to the core of the interpretive dispute: 'presentation' under Article 12(III) should be understood as delivery to the parties in the manner contemplated by Article 29 of the BAA, which requires the arbitrator to send a copy with proof of receipt. On this reading, the award was only 'presented' on 17 March. The STJ upheld the TJSC’s reasoning.

II. STJ's Reasoning: Two Grounds and a Three-Concept Hierarchy

As Guilherme Rizzo do Amaral has observed, the STJ's holding rests on two independent and analytically distinct grounds, each sufficient on its own to dismiss the annulment claim.

According to the first ground, 'presentation' within the meaning of Article 12(III) is completed upon filing of the award in the arbitration record, provided that the award is made accessible to the parties. It therefore does not require formal notification to the parties or sending a copy of the award, as contemplated by Article 29. The STJ's reasoning implicitly constructs a hierarchy between three separate and distinct concepts in the BAA: (i) issuance or rendering: the signing of the award on 12 March; (ii) presentation, Article 12(III): filing in the record on 13 March, sufficient to satisfy the arbitrator's duty to render a timely award; and (iii) notification, Article (33, §1): formal communication to the parties on 17 March, which triggers the ninety-day period for challenge.

By rejecting Dell'Pradi's argument that 'presentation' should be read through the lens of Article 29, STJ kept these concepts separate. What the Court requires for 'presentation' is not formal notice or service, but that the award be filed and effectively made available to the parties. Filing in the record satisfies that requirement. This reasoning is, however, fact-sensitive. The Court noted that the record was accessible to the parties from the date of filing. Had that not been in a digital case management system, the same argument would not automatically hold. Nonetheless, STJ refused to treat a clerical administrative gap as a constitutional defect of the award, keeping its ruling aligned with international consensus and reiterating its pro-arbitration approach.

The second ground is, however, open to debate. As an additional ground for maintaining the TJSC’s judgment, the STJ also observed that the award should be enforced as Dell'Pradi had failed to establish that any actual prejudice had arisen from the two-day delay. As argued by Rizzo do Amaral, Article 12(III) of the BAA itself already contains an absolute presumption in favour of prejudice in case the party triggers the cure clock, but the arbitrator still fails to render the award in time. Requiring additional proof of prejudice on top of evidence that the award was not rendered in time would render that provision meaningless. It also introduces a degree of uncertainty as to when the award should be deemed to have been rendered out of time, which the BAA sought to eliminate by creating clear time limits for issuance, presentation, and notification.

III. An Open Question: Implications for the Ninety-Day Annulment Period

The three-concept hierarchy implicitly established by the Court clarifies the meaning of 'presented' in the sense of Article 12(III), thereby dispelling any doubts as to what steps are required for arbitrators to discharge their duty to render a timely award. It does not, however, address what follows logically from that hierarchy. If the date of 'presentation' (filing in the record) may be distinct from that of 'notification' (formal communication to the parties) for purposes of Article 12(III), from which of the two milestones should the ninety-day period for initiation of annulment proceedings under Article 33, §1 start to run?

The STJ was not called to resolve this issue on the facts and thus did not do so, nor did it provide any guidance in this respect. In this case, Dell'Pradi calculated the ninety-day period from the date of formal notification, not from when the award was filed. This is consistent with the Court's own distinction since it was careful not to elide 'presentation' with 'notification', treating filing as sufficient for the arbitrator's duty to render a timely award while anchoring the time limit for challenge to a different trigger.

This open question acquires additional significance when viewed against the STJ's recent efforts to define the ninety-day period from multiple angles. In December 2025, the Court held in REsp No. 2,212,083/SP that the same deadline for initiation of annulment proceedings applies when nullity is raised in an autonomous annulment action and in defense against enforcement proceedings. Together with this case, these decisions form a coherent and increasingly detailed body of case law on Brazil's temporal framework for the judicial challenging of awards.

Reading these decisions alongside another post on this Blog, which examined the distinct but related question of how the ninety-day period is affected by partial awards and clarification requests, the present case can be read as a supplement. While that post addresses how far the deadline extends, this ruling provides further input as to the equally fundamental question of when and from which specific act it begins. The relationship between 'presentation' and 'notification' for purposes of Article 33, §1 is the next logical step in that line.

The distinction also has practical implications in the context of institutional arbitrations conducted through digital platforms, where the precise moment of 'notification' occurs (by upload, email, or confirmed access), which may generate exactly the same ambiguity that divided the judge from the appellate courts.

The view supported by the STJ's own three-concept hierarchy is that 'notification' under Article 33, §1 should remain anchored to a clearly identifiable act of formal communication to the parties. Somewhat ironically, the very provision the losing party sought to rely upon to define 'presentation' may contain the answer to the open question arising out of the STJ’s decision. Clarity on this point, whether through a future STJ decision, institutional rules, or legislative amendment, would meaningfully strengthen the procedural framework underpinning the finality of arbitral awards in Brazil.

Conclusion

REsp No. 2,210,332/SC makes a timely and useful contribution to Brazilian arbitration law. By confirming that an award is 'presented' when filed in the arbitration record and made available to the parties, and by clearly distinguishing 'presentation' from the separate duty to send a copy of the award to the parties under Article 29, the STJ closes off a category of opportunistic challenges while establishing a three-concept hierarchy that should inform future analysis of the BAA's time-limit regime.

The decision reflects the international consensus that minor breaches of arbitral time limits should not provide grounds for annulment, not least in cases where the delay does not cause prejudice. The rationale that the absence of demonstrated prejudice independently justified dismissal is more debatable.

Finally, the decision leaves open the question as to whether 'notification' under Article 33, §1 refers to the same act as 'presentation' under Article 12(III) or to the separate and distinct act contemplated by Article 29. The better answer, in the author’s view, is that it refers to the latter, consisting of the formal, provable act of communication to the parties contemplated in Article 29. Confirmation as to the correct construction of Article 33, §1, therefore, would close the final gap in the STJ's emerging jurisprudence on time limits in Brazilian arbitration.
