Pulse Analysis

Brazil’s arbitration landscape rests on the Kompetenz‑Kompetenz doctrine, which grants tribunals the first say on their own jurisdiction. Article 8 of the Brazilian Arbitration Law and articles 32‑33 outline a chronological hierarchy that bars courts from reviewing procedural incidents until an award is issued. In Vale v. Shareholders, the São Paulo Appellate Court broke with this hierarchy by nullifying a quasi‑jurisdictional act of the CAM B3 chamber before any arbitrators were seated, raising concerns about the erosion of party‑autonomy safeguards that underpin cross‑border investment confidence.

The TJSP’s reasoning hinged on a narrow view of procedural versus jurisdictional acts, treating the president’s appointment power as merely administrative. Internationally, leading institutions treat such appointments as essential to due‑process and therefore subject to tribunal review, as reflected in the Paranapanema and Dutco precedents. By allowing premature judicial interference, the decision threatens the predictability of arbitration outcomes and could invite similar challenges in other Latin American jurisdictions, where courts occasionally assert broader supervisory roles.

Nevertheless, the Superior Court of Justice has consistently reinforced the primacy of arbitral tribunals, signaling that the TJSP ruling is likely to remain an isolated anomaly. Practitioners should advise clients to embed clear fallback mechanisms in arbitration clauses, such as pre‑agreed appointing authorities, and to be prepared to contest premature court actions through expedited interlocutory appeals. Maintaining vigilance over jurisdictional disputes will help preserve the efficiency and neutrality that make Brazil an attractive venue for high‑value commercial arbitration.
