On 8 April 2026, Brazil's Superior Court of Justice (Superior Tribunal de Justiça, or STJ) decided REsp No. 2,210,332/SC, resolving a narrow but consequential question of timing under the Brazilian Arbitration Act (Law No. 9,307/1996): when exactly is an arbitral award 'presented' for the purposes of the statutory deadline imposed on arbitrators. The decision was analysed by Caio Lopes da Silva on the Kluwer Arbitration Blog on 17 June 2026.
The Portuguese statutory term at issue, apresentação, does not denote an oral presentation or formal service. The dispute turned on whether, for purposes of Article 12(III), an award is 'presented' when it is signed, when it is filed in the arbitration record, or only when the parties are formally notified.
The Act establishes a two-stage time-limit regime. Parties may agree on a deadline for issuance of the award under Article 11(III); absent agreement, the default is six months from the constitution of the arbitral tribunal under Article 23. If that deadline lapses in an arbitration commenced through a submission agreement (compromisso arbitral) rather than an arbitration clause, the mandate is not automatically extinguished. The interested party must first notify the sole arbitrator or presiding arbitrator and grant a further ten days for the issuance and presentation of the award. Only once that cure period expires does Article 32(VII) open the door to an annulment action grounded on delay. A separate provision, Article 33, §1, sets a ninety-day window to bring an annulment action from notification of the award, while Article 29 requires the arbitrator to send a copy to the parties with proof of receipt.
The facts were stark. The arbitration proceeded before a sole arbitrator under a submission agreement, the contractual arbitration clause being incomplete. The parties agreed on a 180-day deadline running from their final submission. When that period passed without a decision, the claimant, Dell'Pradi Imóveis Ltda, notified the arbitrator on 5 March 2015, triggering the ten-day cure period. The award was signed on 12 March and filed in the arbitration record on 13 March, both within the window. The parties, however, were formally notified only on 17 March. Dell'Pradi sought annulment, arguing that 'presentation' occurred only on notification, rendering the award two working days late.
The first-instance court annulled the award. The Court of Appeal of Santa Catarina reversed, holding that formal notification merely informs the parties of something already placed in the record. Dell'Pradi appealed to the STJ, contending that 'presentation' under Article 12(III) should be read through Article 29 and thus completed only upon delivery to the parties.
The STJ rejected that argument and upheld the appellate reasoning. On the Court's first and principal ground, 'presentation' is completed when the award is filed in the arbitration record, provided the award is effectively made available to the parties. It does not require formal notification or the sending of a copy under Article 29. The ruling implicitly constructs a hierarchy of three distinct concepts: issuance, being the signing of the award; presentation, being filing in the record sufficient to discharge the arbitrator's duty to render a timely award; and notification, the formal communication that triggers the ninety-day challenge period. The Court stressed that the record was accessible to the parties from the filing date through a digital case management system, making its conclusion fact-sensitive. It declined to treat a brief administrative gap as a fatal defect, aligning itself with the international consensus that minor breaches of arbitral time limits should not justify annulment.
As a secondary and more contestable ground, the STJ added that the award should stand because Dell'Pradi had not shown actual prejudice from the short delay. Commentators have observed that Article 12(III) already embeds an absolute presumption of prejudice once the cure period is triggered and the arbitrator still fails to render the award in time, so demanding separate proof of harm risks hollowing out the provision.
The decision leaves one question open. If 'presentation' (filing) and 'notification' (formal communication) are distinct acts on distinct dates, from which milestone does the ninety-day annulment period under Article 33, §1 run? The STJ was not required to decide the point. The issue carries practical weight for institutional arbitrations conducted on digital platforms, where the precise moment of notification — by upload, email or confirmed access — may revive the very ambiguity at the heart of this case. The decision sits alongside the STJ's December 2025 ruling in REsp No. 2,212,083/SP, which held that the same ninety-day deadline applies whether nullity is raised in an autonomous annulment action or as a defence to enforcement, forming part of an increasingly detailed body of case law on Brazil's temporal framework for challenging awards.
