Background

Eletropaulo, a major electricity utility in São Paulo, filed a Special Appeal (Recurso Especial) before Brazil’s Superior Tribunal de Justiça (STJ). The STJ’s Presidency declined to admit the Special Appeal, citing four independent grounds for rejection: no violation of the applicable procedural provisions; no violation of substantive law; improper reliance on facts and evidence rather than pure law; and improper attempt to challenge an administrative resolution (ANATEL Resolution 04/2014) rather than a federal law or treaty.

Eletropaulo then filed an internal appeal (Agravo Interno) challenging the Presidency’s decision to reject the Special Appeal. However, in this internal appeal, Eletropaulo did not specifically address or rebut all four grounds cited by the Presidency. Notably, Eletropaulo failed to offer any substantive argument explaining how the STJ could review an administrative regulation without violating the constitutional limits on Special Appeals, which restrict review to violations of federal law or treaties.

The Court’s Holding

The STJ’s Second Panel unanimously denied Eletropaulo’s internal appeal. The court held that under Articles 932(III) of the Brazilian Code of Civil Procedure (CPC) and 253, final paragraph, of the STJ’s Internal Rules (RISTJ), an internal appeal attacking an admissibility decision must specifically and effectively address every ground cited in the rejected appeal—not just some of them. The court emphasized that a decision rejecting a Special Appeal is an integrated whole, not divisible into separate autonomous issues.

The court further clarified that impugning requires “effective, concrete, and detailed” argument, not generic allegations or arguments focused on the underlying merits of the case. By failing to specifically contest the fourth ground (the ANATEL Resolution issue), Eletropaulo violated the “dialeticity principle” (princípio da dialeticidade), which requires appellants to meaningfully engage with the specific reasons for the lower decision. The Presidency’s decision therefore stood, and the internal appeal was not even heard on the merits.

Key Takeaways

  • In Brazilian appellate practice, when challenging a decision that rejects a Special Appeal, advocates must specifically rebut every ground cited in that rejection, not merely some of them.
  • A decision rejecting a Special Appeal is treated as a single, integrated ruling—not as separate divisible parts that can be selectively challenged.
  • Generic or conclusory arguments do not satisfy the dialeticity requirement; arguments must be effective, concrete, and detailed.
  • Failure to meet these procedural requirements results in the appeal being summarily rejected without reaching the merits.

Why It Matters

This decision reinforces strict procedural discipline in Brazilian appellate practice and exemplifies how procedural requirements—not just the underlying law—determine case outcomes. For practitioners handling Special Appeals before the STJ, the holding is a cautionary reminder that partial or incomplete challenges to admissibility decisions will fail, even if some of the underlying arguments have merit. The decision also reflects the Brazilian courts’ commitment to the dialeticity principle, which ensures that appellate review is based on focused, substantive engagement with the prior decision’s reasoning.

The STJ’s emphasis on comprehensive, specific impugning of all grounds applies broadly to all appeals of admissibility decisions and is grounded in longstanding precedent. This case will likely influence how Brazilian advocates draft internal appeals and other second-stage appellate motions.
