Background

CSN Cimentos Brasil S.A. challenged an ISS municipal-services-tax assessment covering October 1998 through July 2003. It contended that materials supplied in concrete services should have been excluded from the tax base. The lower courts rejected that challenge, finding that CSN had not proved the materials were separately commercialized.

The Superior Court of Justice declined to hear the special appeal because determining whether the lower court’s finding conflicted with the expert report would require reassessing evidence, which Súmula 7/STJ prohibits in a special appeal. After an internal appeal and an earlier set of declaratory objections were rejected, CSN filed new declaratory objections, arguing that the court still had not addressed why the dispute allegedly presented only legal questions under the Code of Civil Procedure and Complementary Law No. 116/2003.

The Court’s Holding

The Second Panel unanimously rejected the new declaratory objections. It held that the challenged decision had already addressed the relevant issues and contained no obscurity, internal contradiction, omission, or clerical error within Article 1,022 of the Code of Civil Procedure. Because the underlying special appeal had not been admitted, the court said there could be no omission arising from its failure to decide the unexamined merits.

The court reiterated that a judge need not answer every contention once sufficient grounds for decision have been given, but must address arguments capable of undermining the result. CSN’s effort to obtain reconsideration of the evidentiary bar and the merits did not fall within the limited corrective function of declaratory objections. The formal judgment records rejection “with application of a fine”; the reporting justice’s vote also warned that any further objections repeating the same issue would be deemed manifestly dilatory and subject to a 2% fine under Article 1,026(2).

Key Takeaways

  • Declaratory objections under Article 1,022 correct obscurity, contradiction, omission, or clerical error; they are not a vehicle for relitigating an adverse ruling.
  • When a special appeal is inadmissible, the STJ’s failure to reach its substantive tax arguments does not create an omission concerning those arguments.
  • Determining whether the expert evidence disproved the lower court’s factual finding would require prohibited reconsideration of the evidentiary record under Súmula 7/STJ.
  • Repeated objections raising an issue already resolved may be treated as manifestly dilatory and penalized.

Why It Matters

The ruling underscores the narrow role of declaratory objections in Brazilian appellate practice. Parties cannot use successive objections to bypass an admissibility ruling or secure a merits decision that the STJ could not reach without reassessing evidence.

The court did not decide whether materials used in concrete services are legally deductible from the ISS tax base. Its ruling was procedural: the factual premise necessary to adjudicate that issue could not be revisited in the special appeal.
