Cognition, within the scope of Procedural Law, encompasses the magistrate's intellectual activity aimed at the knowledge, analysis, and valuation of the facts and legal grounds presented by the parties, constituting the core of jurisdictional provision. Essential to Civil and Criminal Procedural Law, its primary purpose is the formation of the reasoned conviction necessary for the delivery of jurisdictional protection, whether declaratory, constitutive, or condemnatory.
Concept and Legal Nature
Legal cognition is defined as the mental and logical procedure by which the judge gains knowledge of the dispute, examining the claim and the resistance in order to issue a final ruling under the scrutiny of the adversarial system. The legal nature of cognition is that of a state function of exercising jurisdiction, embodied in the duty-power to judge.
Doctrinally, cognition is classified according to its depth and extent. Exhaustive cognition is that which allows the magistrate an in-depth examination of all evidence and allegations, culminating in a final and unappealable judgment (res judicata). Conversely, summary cognition, typical of provisional remedies (urgent or evidence-based), is based on a judgment of probability (fumus boni iuris) and is, by nature, revocable or modifiable.
Historical Origin and Evolution
The concept dates back to Roman Law, specifically in the cognitio extra ordinem system, where the magistrate began to exercise judgment directly, overcoming the system of legis actiones and the formulary procedure. In the Brazilian legal system, the evolution reflects the transition from the exacerbated formalism of the 1939 Code to the instrumentality of the process, consolidated by Law No. 13.105/2015 (Civil Procedure Code - CPC/15), which valued cooperation and the primacy of judgment on the merits.
Legal Provision and Normative Structure
Cognitive activity finds direct support in the provisions governing the formation of the judge's conviction:
- Federal Constitution, art. 93, IX: Establishes the duty to provide reasons for decisions, a requirement inseparable from cognition, under penalty of nullity.
- CPC/15, art. 371: Enshrines the principle of free reasoned conviction, guiding cognition regarding the evidentiary set.
- CPC/15, art. 300 and 311: Delimit summary cognition, allowing the granting of remedies without the exhaustion of full adversarial proceedings, aiming at the effectiveness of the practical result.
Practical Application and Jurisprudence
Current jurisprudence, especially within the Superior Court of Justice (STJ), reinforces that cognition must be guided by strict observance of substantial adversarial proceedings. In the judgment of repetitive appeals, the STJ has reiterated that cognition cannot exceed the objective limits of the dispute (principle of adstriction or congruence), under penalty of an extra petita judgment.
Recently, the Supreme Federal Court (STF), when analyzing topics of general repercussion, has emphasized that cognition in the context of concentrated constitutional review requires a differentiated technical rigor, where the depth of factual analysis gives way to the density of constitutional normative interpretation.
Related Principles and Doctrinal Divergences
The institute of cognition is inseparable from the following principles:
- Principle of Adversarial Proceedings (art. 5, LV, CF/88): The judge's cognition is limited and directed by the parties' manifestations.
- Principle of Primacy of Judgment on the Merits (art. 4, CPC): Cognitive activity must seek, whenever possible, the resolution of the conflict in its essence, avoiding dismissals without resolution of the merits due to formalism.
Doctrinal divergences persist regarding "ex officio cognition" in matters of public order. While part of classical doctrine defends the expansion of the judge's investigative powers (judicial activism), guaranteeist currents maintain that cognition should be strictly restricted to what was brought by the parties, preserving the impartiality of the judge.
Contemporary Relevance
In the current legal scenario, marked by digitalization and the need for speed, cognition faces the challenge of "algorithmic cognition." The use of Artificial Intelligence tools for case screening and assistance in drafting minutes imposes a critical reflection on the maintenance of human cognitive activity. The Judiciary must ensure that speed does not supplant the quality of merit analysis, keeping the judge as the ultimate guarantor of the correct application of the Law.
