As Dr. Bruno Garcia Redondo explains, jurisprudence is one of the most relevant pillars of the Brazilian legal system, as it directly contributes to the stability and predictability of judicial decisions. Therefore, understanding how jurisprudence works in practice is essential for lawyers, judges, and citizens who want to grasp the direction the judiciary is taking.
That’s because the standardization of legal interpretations not only strengthens legal certainty but also ensures that similar cases receive compatible outcomes. With that in mind, keep reading to understand the role of this important legal tool and how it directly affects rulings across the country.
What Is Jurisprudence and What Role Does It Play in the Legal System?
Jurisprudence refers to the set of repeated court decisions on a given legal topic. When higher courts, such as the Federal Supreme Court (STF) or the Superior Court of Justice (STJ), consistently rule in a certain way, a jurisprudence is formed. According to Bruno Garcia Redondo, this repetition of reasoning provides greater stability in decisions, preventing contradictions in the judgments of similar cases.

The main function of jurisprudence is to promote uniformity in the application of the law. By following interpretations consolidated by higher courts, lower-court judges begin to rule based on understandings that are recognized as legitimate and consistent. This ensures greater predictability for citizens and companies regarding the legal consequences of their actions.
How Does Jurisprudence Influence Judicial Decisions?
Jurisprudence has a practical and direct impact in courtrooms. As prosecutor Bruno Garcia Redondo points out, when a judge is faced with a case that has already been widely ruled upon by higher courts, they tend to follow the existing jurisprudence to avoid contradictions. This becomes even more relevant in a context of high judicial demand, where the speed and consistency of decisions are crucial.
Moreover, there are legal mechanisms that make jurisprudence even more powerful. The new Code of Civil Procedure (CPC), for example, includes tools such as the judgment of repetitive appeals and the “general repercussion” mechanism, which strengthen the effectiveness of standardized decisions. When an issue is settled by the STF or STJ, lower courts must follow that interpretation, except in exceptional cases.

In What Situations Is Jurisprudence Mandatory?
There are cases in which judges are legally required to follow jurisprudence, especially when it is consolidated in specific forms established by law. According to Dr. Bruno Garcia Redondo, failure to comply with these precedents may lead to the annulment of a judicial decision or its reversal by higher courts. Below are the main types of binding jurisprudence:
Binding Precedents (Súmulas Vinculantes): Issued by the STF, they are mandatory for all judicial bodies and public administration, both direct and indirect.
Repetitive Appeals: Decisions made in cases involving a large number of similar lawsuits, serving as a reference for future rulings.
General Repercussion: Used by the STF to filter relevant issues that impact a significant portion of society.
Incidents of Repetitive Demand Resolution (IRDR): Judgments of recurring themes by state courts and federal regional courts.
These instruments not only help organize the judiciary but also prevent large-scale contradictory rulings, promoting a more cohesive and functional legal system.
The Benefits of Jurisprudence for the Judicial System
Jurisprudence not only guides decisions but also brings significant improvements to the efficiency of the justice system. According to Bruno Garcia Redondo, the standardization of rulings provides benefits for both the judiciary and the people subject to it. The main advantages include:
Legal Predictability: Citizens know in advance what decisions are likely in similar cases.
Procedural Speed: By following established understandings, judges save time and reduce the number of appeals.
Reduced Litigation: When jurisprudence is clear, many opt to resolve disputes without resorting to court.
Institutional Security: Uniform decisions strengthen confidence in the judiciary’s performance.
In this way, jurisprudence functions as a rationalization mechanism for justice, contributing to a more balanced, predictable, and accessible legal system.
Jurisprudence and Legal Stability: Why This Relationship Matters
Maintaining consistency in rulings is essential to ensuring public trust in the justice system. Jurisprudence serves as a crucial tool to consolidate this stability. When courts maintain coherence in their decisions, they convey security to both individuals and businesses. This legal predictability influences strategic decisions, investments, and even social behaviors. In other words, a system with solid jurisprudence contributes to institutional strengthening and upholding the rule of law.
Jurisprudence as the Foundation of a More Efficient Judiciary
In conclusion, jurisprudence is much more than a record of decisions — it is an instrument that guides, standardizes, and strengthens the judiciary. By promoting consistency across rulings, it reduces uncertainty, prevents contradictions, and provides clear guidelines for lawyers, judges, and citizens alike. Therefore, its role is increasingly relevant in today’s complex legal landscape, where efficiency, predictability, and justice must go hand in hand.
