Preclusion

1. Definition, Concept, and Legal Nature

Preclusion is a public order institute that acts as a mechanism for closing procedural stages. From the perspective of general procedural theory, it is defined as the loss, extinction, or consummation of a procedural power. Giuseppe Chiovenda, a precursor to the systematization of the subject, defines it as the "loss of a procedural power that occurs due to the failure to observe the order assigned by law for its exercise."

Regarding its legal nature, preclusion is classified as an impeding procedural legal fact. It does not extinguish the substantive right itself, but rather the capacity to exercise rights and powers within the procedural legal relationship. It differs from prescription and decadence by operating exclusively intra-procedurally, aiming at the stabilization of the procedure and the effectiveness of jurisdictional provision.

Classical and contemporary doctrine subdivides the institute into three fundamental modalities:

• Temporal Preclusion: Arises from the party's inertia in performing the act within the peremptory or dilatory deadline set by law or by the magistrate.
• Logical Preclusion: Arises from the performance of an act incompatible with the power one intended to exercise (e.g., express or tacit acceptance of a decision prevents the filing of an appeal).
• Consumptive Preclusion: Occurs when the procedural power has already been exercised, and cannot be repeated or supplemented, unless there is a specific legal provision.

2. Historical Origin and Evolution in Law

The origin of the term refers to the Latin praeclusio (closing). In Roman Law, although modern systematization did not exist, the system of formulas and the division of the process into phases (in iure and apud iudicem) already imposed rigorous limits on the exercise of powers. However, it was with the Italian school, notably through the work of Giuseppe Chiovenda in the early 20th century, that preclusion was elevated to the category of a fundamental principle for the autonomy of Procedural Law.

In Brazil, the evolution of the institute followed the transition from the 1939 Code of Civil Procedure to the 1973 one, consolidating itself in a more sophisticated way in the 2015 CPC. The Brazilian legislator sought to balance the rigidity of preclusion with the principle of the primacy of merit judgment, allowing, in exceptional situations, the overcoming of formal defects to ensure material justice.

3. Legal Provision and Normative Structure

The 2015 Code of Civil Procedure (CPC/15) regulates preclusion in a scattered and specific manner, with the following provisions standing out:

• Article 223: Establishes that, once the deadline has passed, the right to perform or amend the procedural act is extinguished, regardless of judicial declaration, except for just cause.
• Article 507: Prohibits the party from discussing in the course of the lawsuit issues already decided regarding which preclusion has occurred (Pro Judicato Preclusion for the parties).
• Article 1,000: Deals with logical preclusion by providing that the party who expressly or tacitly accepts the decision may not appeal.
• Article 278: Provides for preclusion regarding nullities, which must be alleged at the first opportunity the party has to speak in the records, under penalty of healing.

In the scope of Criminal Procedure, Article 571 of the CPP lists the opportune moments for arguing nullities, under penalty of preclusion. In Labor Law, the principle of immediacy and the concentration of acts in hearings reinforce the application of the institute to avoid undue prolongation of the case.

4. Practical Application and Jurisprudential Understanding

The jurisprudence of the Superior Courts has refined the application of preclusion to avoid so-called "procedural regression."

Superior Court of Justice (STJ): The Court consolidated the understanding that public order matters, although not subject to temporal preclusion for the parties as long as they have not been decided, are subject to consumptive or pro judicato preclusion once they have been the object of a previous judicial decision (AgInt in AREsp 1,560,104/SP). Another relevant point is the thesis of the "mitigated taxativity" of the interlocutory appeal (Repetitive Theme 988), which directly impacts preclusion: if the issue is not urgent and does not admit an immediate appeal, preclusion does not occur, and it may be raised in the preliminary of an appeal (Art. 1,009, §1º, CPC).

Supreme Federal Court (STF): The STF strictly applies preclusion in the scope of extraordinary appeals. The absence of specific challenge to all grounds of the appealed decision attracts the incidence of Precedent 283, with preclusion operating on the points not contested. In criminal proceedings, the STF understands that the nullity of questioning in the Jury Tribunal must be argued immediately after its reading, under penalty of preclusion (Art. 571, VIII, CPP).

Superior Labor Court (TST): Preclusion is applied vigorously regarding the moment of presenting calculations and challenges in the liquidation phase (Art. 879, §2º of the CLT), as well as in the pre-questioning of matters for the purposes of the Review Appeal (Precedent 297).

5. Correlated Principles and Doctrinal Divergences

Preclusion dialogues directly with the following principles:

• Legal Certainty: Ensures that past acts are not revisited indefinitely.
• Procedural Good Faith: Prevents contradictory behaviors (venire contra factum proprium), the basis of logical preclusion.
• Reasonable Duration of the Process: Preclusion is the engine that drives the procedure toward the sentence.

A relevant divergence lies in Pro Judicato Preclusion. While part of the doctrine argues that the judge never precludes on public order matters, the dominant jurisprudence (STJ) maintains that, once the issue is decided (e.g., standing to be sued), the magistrate cannot re-decide it in the same degree of jurisdiction, except in the event of a new fact.

6. Contemporary Relevance and Impacts on the Legal System

In the scenario of contemporary civil procedure, marked by digitalization and the search for swift results, preclusion acts as the main antidote against procedural chicanery and bad-faith litigation. With the introduction of Procedural Legal Transactions (Art. 190, CPC), the parties can even agree on procedural calendars that alter the dynamics of temporal preclusions.

An exact understanding of the institute is indispensable for strategic advocacy. The loss of a deadline or the performance of an incompatible act can seal the fate of a claim, regardless of the underlying substantive right. Therefore, preclusion is not just a sanction, but an organizational rule indispensable for the viability of the Democratic State of Law and for the effectiveness of jurisdiction.
