The interpretation and application of laws are fundamental aspects of the legal system, ensuring justice and equity in judicial decisions. However, the complexity of legal scenarios often creates difficulties in understanding and consequently in applying legal standards. This can lead to the imposition of exorbitant fines, resulting in unfair situations. 1. Difficulties in legal interpretation: The interpretation of laws is a challenging task due to their complex nature and the multiplicity of possible understandings. The courts and the Superior Court of Justice (STJ), as the body responsible for standardizing the interpretation of federal law, face difficulties in establishing a consensus on the criteria to be followed. 2. Complexity of concrete cases: Each legal case is unique, with its particularities and specific circumstances. The application of laws in these cases requires a thorough analysis, considering each aspect relevant to decision-making. However, this complexity often makes it difficult to reach a clear and objective conclusion, making it difficult to fairly apply fines. 3. Strictness of the procedure: Judicial procedures follow strict standards, established to guarantee the impartiality and legality of decisions. However, this rigidity can become a barrier to the flexibility necessary to adequately analyze each case on its own. A lack of room to consider specific circumstances can lead to exorbitant and unfair fines being maintained. 4. Exorbitant fines and injustice: When the difficulties of legal interpretation and the rigidity of the procedure combine, the result can be the imposition of exorbitant fines. These penalties may not proportionally reflect the seriousness of the infraction committed, harming justice and creating situations of injustice. Conclusion: The difficulty in legal interpretation, the complexity of the cases and the rigidity of the procedure contribute to the imposition of exorbitant fines, often resulting in injustice. To overcome these challenges, it is essential that the courts and the STJ seek to improve their interpretative capacity, establish clear criteria for the application of fines and make procedures more flexible to consider the particularities of each case. Only with these measures will it be possible to guarantee justice and equity in legal decisions.

This article aims to analyze the effects of default in the Brazilian legal system, considering its occurrence and estoppel. Default occurs when the defendant does not present a defense or does not appear in the case, generating consequences in relation to the production of evidence, presumption of veracity of the facts alleged by the author and granting of procedural benefits. In this study, a survey will be carried out of the main legal provisions and jurisprudential understandings, both infra-constitutional and infra-constitutional, that address the matter. In the Brazilian legal system, by default is a situation that occurs when the defendant does not present a defense or does not appear in the case, resulting in consequences that vary according to current legislation. Default is a relevant topic in the legal context, both for the doctrinal field and for the practical actions of legal professionals. In this article, an analysis will be made of the effects of default, considering its occurrence and estoppel, based on infraconstitutional and infraconstitutional grounds. 1. Concept of default and its occurrence Default occurs when the defendant does not offer a defense or does not appear in the case within the legal deadline. In this scenario, the process continues normally in relation to the plaintiff, without the need to wait for the defendant's defense. The most fundamental legal provision that deals with default is article 344 of the Code of Civil Procedure, which establishes the effects arising from the lack of defense. 2. Effects of default on civil proceedings - Presumption of veracity: one of the main effects of default is the presumption of veracity of the facts alleged by the author. Those factual and legal aspects alleged in the initial petition are now presumed to be true, except in cases where the law establishes otherwise. - Burden of proof: with default, the burden of proof is reversed. This means that the plaintiff will not need to produce evidence about the facts alleged in the initial petition, and it will be up to the defendant to try to prove the opposite. - Procedural prerogatives: the defaulting defendant may have his rights curtailed in relation to procedural prerogatives, such as taking a personal statement from the plaintiff, producing testimonial evidence and presentation of expert questions. 3. Preclusion of default Preclusion is the loss of a procedural faculty, occurring in various situations provided for by law. In the specific case of default, there are limits to the application of the effects of non-challenge. For example, the defendant in default may manifest himself at a later time, before the sentence is handed down, requesting the performance of a certain procedural activity or specifically contesting some of the facts alleged by the author. 4. Applicable jurisprudence The jurisprudential practice in relation to the effects of default is diverse. Some courts understand that, even in default, it is necessary for the author to produce evidence to support the alleged facts. Other courts adopt the position of absolute presumption of veracity of the facts alleged in the initial petition. The analysis of these jurisprudential positions is essential to guide the actions of legal practitioners in specific cases. Conclusion: Default is a procedural institute that brings relevant effects to the Brazilian legal system. Its effects may vary according to current legislation and the doctrinal and jurisprudential interpretation applied. It is important that legal professionals are aware of the effects of default and its estoppel, in order to guarantee the correct application of the law and respect the fundamental principles of civil procedure.

In the Brazilian legal system, the obligation propter rem of the property is a fundamental figure to guarantee the social function of property and protect the collective interests of third parties. Through this obligation, the owner of a property is legally bound to certain responsibilities, regardless of whether or not he is directly responsible for the situation that generated the obligation, according to the Civil Code and Federal Constitution.

In this sense, the obligation propter rem is strictly related to the social function of property, being essential to guarantee the harmony and balanced development of urban areas. The practical application of the obligation propter rem can be observed in several cases, such as the owner's responsibility to pay condominium fees, even if he does not live in the property, IPTUS, or the obligation to keep the property in good condition to preserve the safety of neighbors and the community in general. These obligations arise directly from the link between the property and the rights of third parties or collective well-being, regardless of the owner's personal relationship with these rights or interests. Conclusion: This time, we can conclude that the obligation propter rem of the property is an essential legal figure to guarantee the protection of collective and third-party interests, as well as to ensure compliance with the social function of the property. Based on the Civil Code and supported by the Federal Constitution, this obligation establishes that certain responsibilities are inherent to the property, regardless of who the owner is. The mandatory obligation propter rem is crucial for social order and urban development, promoting harmony between individual and collective rights and ensuring the preservation of the well-being of the entire community. In addition, balancing the interests of the parties involved, establishing responsibilities and ensuring legal certainty, however, it is necessary for legal operators to act coherently, considering the particularities of each case and promoting justice in the context of real estate relations. Regardless of the notes declining the obligation propter rem it continues to be the subject of studies and debates in doctrine and jurisprudence, whatever view new challenges that arise with constant social and technological transformations, therefore requiring constant evolution of law to keep up with these changes.

We also explore the processes of drafting, discussing and approving laws, as well as the role of the Legislature in controlling the Executive's actions. 3. Judiciary: Guarantee of Rights and Control of Constitutionality: The role of the Judiciary in protecting the fundamental rights of citizens, its role as an interpreter of the Constitution and its responsibility to guarantee justice and impartiality. We also explore constitutionality control mechanisms, such as direct action for unconstitutionality, which allow the Judiciary to supervise the conformity of laws with the Constitution. 4. Institutional Balance and Separation of Powers: The importance of institutional balance to avoid excessive concentration of power in a single body or individual. We discuss how the system of checks and balances between powers seeks to ensure that no power governs arbitrarily, guaranteeing the protection of citizens' rights. 5. Contemporary Challenges: Current challenges, such as the need to improve transparency and accountability, as well as independent action in a complex political environment. Ethical and practical dilemmas are also discussed, such as the relationship between the justice system and political powers.

This article addresses the form of constitutionality control in Brazil, investigating its mechanisms, legal basis and the impact that its decisions generate on the country's legal order. With both the Federal Constitution and jurisprudence as a backdrop, this study explores how constitutionality control acts as an essential pillar in guaranteeing constitutional supremacy and protecting fundamental rights, while maintaining the cohesion and concatenation of the analyzes carried out. Constitutionality control, as a cornerstone of the Rule of Law, presents itself as a vital instrument to maintain the integrity of the Brazilian legal system. This article aims to dissect the different mechanisms through which constitutionality control occurs, evaluating the underlying legal support and exploring the repercussions that such decisions have on the country's legal order. 1. Constitutionality Control Mechanisms: Brazil adopts a hybrid system of constitutionality control, encompassing diffuse and concentrated systems. In the diffuse system, any magistrate or court, upon finding the possible incompatibility of a law with the Constitution, can apply the principle of non-reception, ensuring that the unconstitutional rule is not applied in the specific case. In the concentrated system, through Direct Actions of Unconstitutionality (ADIs) and Declaratory Actions of Constitutionality (ADCs), the Federal Supreme Court (STF) assumes the prerogative of being the last instance to resolve issues of unconstitutionality, providing uniformity to decisions and avoiding jurisprudential heterogeneity. 2. Supremacy of the Constitution and Protection of Fundamental Rights: The legal basis of constitutionality control rests on the premise of the supremacy of the Constitution, established in article 102 of the Federal Constitution of 1988. This principle, combined with article 5, which enshrines the rights and fundamental guarantees, gives rise to the declaration of unconstitutionality of rules that contradict these provisions. In this sense, constitutionality control plays a crucial role in the protection of fundamental rights, ensuring harmonization between normative acts and constitutional precepts. 3. Impact on Legal Relations: Decisions made in constitutionality control processes have effects that transcend the parties involved in the litigation. The binding force of these decisions, as provided for in article 102, § 2, of the Constitution, extends to all bodies of the Judiciary and public administration, impacting the validity and effectiveness of the rules declared unconstitutional. 4. Constitution and Jurisprudence as Sources of Constitutionality Control: The control of constitutionality, intrinsically linked to the Federal Constitution, finds a normative basis in article 102, section III, which gives the STF the competence to judge ADIs and ADCs. Furthermore, the STF's consolidated jurisprudence plays a fundamental role in establishing interpretative parameters, supporting the coherence and predictability of decisions. 5. Limits and Challenges of Constitutionality Control: Despite its importance, constitutionality control also faces challenges, such as excessive judicialization and an overload of demands at the STF. The complexity of some cases can generate heated debates and interpretative disputes, demonstrating the need for a balance between legal stability and flexibility in adapting to social changes. Conclusion: The constitutionality control system in Brazil, anchored in the Constitution and supported by jurisprudence, plays a fundamental role in maintaining the legal order, safeguarding fundamental rights and preserving supremacy constitutional. Its mechanisms and decisions shape legal relations in the country, while contributing to the evolution of the Brazilian legal framework.

Interaction between Powers: Checks and Balances: The interaction between powers, highlighting the notion of "checks and balances" (checks and balances) as a reciprocal control mechanism. We analyze how each branch exercises oversight functions over the others, preventing abuses and ensuring respect for constitutional principles. 5. Institutional Balance and Contemporary Challenges: The importance of institutional balance in maintaining democracy and the rule of law. We address current challenges, such as the search for greater transparency and accountability, the need to avoid excessive politicization of the Judiciary and the joint action of powers to address urgent issues. Conclusion: Therefore, the organization of powers is a central element in Brazil's political structure, contributing to the preservation of democracy and citizens' rights.
