The relevance filter for a special appeal to the Superior Court of Justice (*recurso especial*) takes effect on September 3, 2026 and changes the economics of asset-related litigation: the state appellate decision tends to become final sooner.
What happened
Law No. 15,484 of August 4, 2026 — published in an extra edition of the Federal Official Gazette that same day — regulates the relevance regime for questions of federal statutory law as a condition for admission of special appeals to the STJ, provided for in Art. 105, §§ 2 and 3, of the Constitution since Constitutional Amendment No. 125/2022, and adds Art. 1,035-A to the Code of Civil Procedure (CPC):
Art. 1,035-A. The Superior Court of Justice, in an unappealable decision, shall decline to hear a special appeal when the question of federal statutory law addressed therein is not relevant under this article.
Once the law takes effect, the appellant must demonstrate, in a specific, reasoned section of the special appeal petition, that the question at issue transcends the parties' individual interests — through economic, political, social, or legal relevance. Without that showing, the appeal will not be heard.
Art. 105, § 3, of the Constitution presumes relevance in six situations: I — criminal actions; II — administrative misconduct actions; III — actions whose amount in controversy exceeds 500 minimum wages; IV — actions that may result in ineligibility for elected office; V — cases in which the appealed decision contradicts the STJ's prevailing case law; VI — other situations provided by law.
Two safeguards matter to the practical calculation. The first is in Art. 105, § 2, of the Constitution: the STJ "may decline to hear it on this ground only by a vote of 2/3 (two-thirds) of the members of the body competent to decide it" — rejection requires a supermajority. The second is the transition rule, in Art. 4 of Law No. 15,484/2026 itself: the requirement for a relevance section applies to appeals filed against appellate decisions published after the law takes effect. The benchmark is the publication date of the appealed decision, not the date the appeal is filed — and, under the operational interpretation adopted by the STJ in Internal Rules Amendment No. 55, this means appellate decisions published on or after September 3, 2026.
The internal rules amendment also includes two qualifications worth knowing: special appeals against appellate decisions published before the effective date may be subjected to the relevance regime to establish a binding precedent, and pending repetitive appeals already designated for representative adjudication are, as a rule, deemed to have recognized relevance.
The technical reading
What changes is not just one procedural rule among others. It is the economics of asset-related litigation in Brazil.
For four decades, the special appeal functioned as a de facto third level of review. A party that lost in state court had, with reasonable predictability, one more round in Brasília — and with it, another two, three, four years. That interval had economic value of its own, regardless of the merits: it was time. The debtor gained time; the party in the right financed the wait. Starting September 3, that interval can no longer be presumed. It becomes something earned by showing that the dispute matters to more people than the parties.
For creditors, this is the year's most favorable change. The state appellate court's decision tends to become final sooner, and the strategy of resisting through appeals loses much of its payoff. For debtors who were counting on successive appeals, the calculation reverses: settlement becomes worth more, and sooner.
The presumption based on an amount in controversy exceeding 500 minimum wages deserves particular attention from those litigating over assets. It creates a concrete asymmetry: higher-value cases retain presumed access to the STJ, while medium-value disputes — much of the litigation involving families, condominiums, real estate contracts, debt collection, and civil liability — become dependent on a reasoned showing. The amount in controversy stated in the initial complaint, a matter often handled carelessly, now has direct appellate consequences.
There is also a short-term effect that will quickly expire. Because the criterion is the publication date of the appealed decision, cases in which the state appellate court's decision is published on or before September 2, 2026 are not subject to the relevance-section requirement. This means that two identical litigation portfolios may have different appellate horizons, determined by a publication date over which neither party has control.
Who this reaches
- Companies with portfolios of delinquent debts in judicial collection or enforcement
- Parties to enforcement proceedings, contract disputes, eviction actions, or disputes over security interests
- Families involved in contested probate, distribution, or determination of support
- Buyers and sellers litigating over real estate, contract terminations, and real estate development
- Business owners in disputes over companies, valuation of a departing owner's equity interest, or expulsion of a member
- Any party whose case is currently awaiting an appellate ruling at the second level of jurisdiction
What to do, and by when
- Identify, by September 2, which cases in the portfolio already have a published second-level appellate decision. Those remain under the old regime; the others do not. This screening can only be done now.
- Reassess the economic value of pending settlements in light of the new horizon. An offer rejected on the assumption of three more years of appeals may be a good offer on the assumption that the judgment will become final and unappealable within months.
- Treat the amount in controversy as a technical decision from the initial complaint onward, not as a formality — it now determines whether relevance is presumed or must be established.
- In cases where a special appeal matters to the strategy, structure the relevance showing from the merits phase onward — identifying the federal question, any prevailing STJ case law contradicted, and the reach of the dispute beyond the parties.
- Review accounting provisions and collection expectations for claims in litigation, whose realization period tends to shorten.
The cost of inaction
Anyone entering September with a portfolio still calibrated to the old regime negotiates poorly — rejecting good settlements and accepting bad ones — based on an appeal period that no longer exists.
