The weight of solitary pens in the country's legal machinery

In the daily routine of public power, the signature of a single magistrate has the power to suspend laws approved by hundreds of elected representatives, paralyze major infrastructure projects, or redefine the nation's fiscal course within a matter of hours. This mechanism of individual power, originally conceived to give celerity to emergency situations, has transformed into one of the most influential and debated axes of the Brazilian state machinery. The result is a scenario where the scales of justice often oscillate according to the isolated conviction of those who occupy a prominent seat in the higher courts.

What is an individual decision in justice and how it works

In legal jargon, the act of deciding in a monocratic manner means that a single judge delivers a sentence or injunction without submitting the issue to the scrutiny of their peers who make up the same collegiate body. While the standard operation of a court of justice presupposes debate among multiple judges, the monocratic route shortcuts this process for reasons of urgency. When the rapporteur of a case identifies an imminent risk of irreparable harm to a right, they can intervene immediately.

This prerogative exists to prevent the natural delay of procedural progress from rendering the object of the action useless. In theory, the measure serves as a rapid remedy to contain urgent abuses or guarantee fundamental rights under flagrant threat. However, in contemporary practice, the use of this tool has expanded beyond exceptional cases of calamity or extreme urgency. It has come to be employed in complex litigation of national repercussion, often replacing the in-depth debate that would take place in the plenary session of the courts.

The operational cycle of this mechanism begins when a lawsuit arrives at the office and is distributed to a rapporteur. Upon analyzing the initial request, the magistrate assesses whether the legal requirements for urgent relief are present. If they understand that they are, the order is issued without hearing the opposing party and without consulting the other members of the collegiate body. Although the rule dictates that this monocratic decision must subsequently be submitted to the panel or plenary for confirmation, the volume of cases often prevents this review from happening in a timely manner.

The historical evolution of isolated decision-making power

The concentration of decision-making powers in individual hands in the country's upper courts did not happen by chance; it is the result of successive institutional reforms accumulated over decades. In the mid-20th century, with the densification of social demands and redemocratization, the volume of cases reaching the highest instances of the Judiciary grew exponentially. The original model, designed for courts that judged few cases of strictly constitutional relevance, collapsed in the face of the avalanche of litigation.

To prevent the total paralysis of the judicial machinery, legislators and the courts themselves expanded the attributions of the rapporteurs. Regimental rules were created allowing individual judges to deny follow-up to appeals deemed unviable or to grant injunctions in writs of mandamus and actions for the control of constitutionality. The initial objective was purely administrative and flow management: to filter what did or did not deserve the precious time of an entire collegiate body.

Over the years, however, this procedural management tool acquired contours of substantive political power. The expansion of access to justice and the judicialization of political and economic themes transformed the rapporteur into a central actor in the national debate. What was a technical expedient to clear shelves became a daily instrument of governance through law, altering the traditional dynamics among the powers of the Republic.

How the mechanism operates behind the scenes of power

The practical operation of a monocratic order reveals the outsized force that a single office holds in the Brazilian institutional design. When a political party, a class entity, or the Prosecutor-General of the Republic files a direct action of unconstitutionality, the case falls into the hands of a rapporteur chosen by a draw. From that moment on, the fate of a public policy of national impact depends on the legal reading of that specific individual.

The step-by-step process of this intervention usually follows its own dynamic:

• The author of the action presents the injunction request alleging urgency and the unconstitutionality of a norm.
• The rapporteur analyzes the petition in their office, assisted by their team of auxiliary judges and legal advisors.
• Without the vote of any other magistrate, the rapporteur signs the decision that totally or partially suspends the effectiveness of the law.
• The order is immediately communicated to the competent authorities, who are obliged to comply with it under penalty of the crime of disobedience.
• The case is released for inclusion in a virtual or in-person trial agenda, the date of which often also depends on a decision by the rapporteur themselves.

This flow demonstrates that the rapporteur holds control not only over the content of the decision but also over the temporal rhythm in which it will be submitted to their peers. If the monocratic order remains in force for months or months without going to the plenary, the practical effect of the measure becomes consolidated, regardless of what the majority of the court may decide in the future.

Volume concentration and the time factor

The volume of monocratic decisions handed down annually in the country's apex courts reveals a structural imbalance in jurisdictional delivery. While a tiny fraction of cases goes through the collective scrutiny of the physical or virtual plenary, the vast majority of cases are resolved by individual dispatches and sentences from each rapporteur. This dynamic creates an office-based justice, where statistical efficiency is achieved at the cost of collegiate deliberation.

The time factor is the most critical element of this equation. An order issued by a single judge has immediate effect, while review by a collegiate body depends on congested dockets. Often, the collegiate body takes months to judge the merits of an injunction, a period during which the factual situation generated by the monocratic decision becomes irreversible. In economics and politics, this time lapse is frequently definitive, hollowing out the meaning of subsequent collective deliberation.

Furthermore, the disparity in each magistrate's individual production generates asymmetries in the system. While some rapporteurs choose to quickly submit their decisions to the collegiate body, others keep cases under their exclusive tutelage for long periods. This variation in individual behavior introduces a degree of unpredictability into the legal system, as the outcome of a demand may depend less on the court's consolidated jurisprudence and more on the drawn rapporteur's methodological preference.

Myths and misconceptions about individual judicial control

Public debate on monocratic action is often permeated by simplifications that obscure the real functioning of institutions. The first major myth is the idea that the judge acts entirely in isolation and without any legal backing. In reality, procedural legislation and internal regulations expressly confer this competence on rapporteurs precisely to safeguard the effectiveness of jurisdictional relief at critical moments.

Another common misconception is to treat the individual decision as something definitive and irrevocable. Although the power of an injunction is strong, the legal system provides mechanisms for reversal, such as the internal interlocutory appeal (agravo regimental), an appeal through which the injured party can demand that the case be taken immediately for a vote by the collegiate body. The problem, however, lies in the court's capacity to schedule and judge this appeal with the necessary speed, rather than in the formal non-existence of the defense mechanism.

There is also frequent confusion between legitimate judicial activism and abuse of prerogative. The use of monocratic decisions is not inherently harmful; it is indispensable for the functioning of a mass justice system in a continental country. The core issue is not the existence of the instrument, but the scope of its application and the delay in collegiate review, aspects that frequently generate institutional friction and legal insecurity.

What changes in the practical life of the citizen and institutions

For the common citizen, the impact of monocratic decisions manifests itself in the volatility of the rules governing life in society. When a single magistrate suspends tax legislation, alters labor norms, or interferes in public health policies, the practical lives of millions of people are shaken overnight. Companies that planned investments based on stable regulatory frameworks find themselves facing scenarios of profound legal uncertainty.

In public institutions, the effect is the paralysis of state planning. Public managers of states and municipalities frequently report the difficulty of implementing long-term policies when there is a constant risk that an individual stroke of a pen will interrupt the program halfway through. This generates an environment of excessive caution in public administration, where project execution remains hostage to the expectation of future judicial decisions.

The economic system also suffers the reflexes of this insecurity. Domestic and foreign investors demand predictability to allocate capital. When the validity of contracts and the fiscal framework depend on the individual interpretation of rapporteurs in higher courts, the cost of credit tends to rise and the attractiveness of infrastructure projects diminishes, making national development more expensive.

Frequently asked questions about the single-decision system

1. Can a monocratic decision be overturned by the plenary?

   Yes. The collegiate body has full authority to amend, confirm, or overturn the decision handed down by any rapporteur, whether through a judgment on the merits or through appeals filed by the parties.

2. Why do judges prefer to decide alone instead of taking cases to the plenary?

   This is not necessarily a matter of personal preference, but a logistical necessity arising from the massive volume of cases. Collegiate judgment requires a physical or virtual docket, whereas an individual decision relieves the office's workflow.

3. Is there a time limit for a monocratic decision to be reviewed?

   The internal rules of the courts provide deadlines for the release of cases, but in practice, the rigorous enforcement of these deadlines faces operational barriers and the chronic accumulation of work in the courts.

The balance between celerity and collective deliberation

The central challenge surrounding monocratic decisions lies in the permanent pursuit of the equilibrium point between the urgency necessary to guarantee rights and the democratic legitimacy that only collegiate debate can confer. An efficient legal system cannot dispense with the agility that individual power provides, nor can it tolerate the exception becoming the permanent rule of governance. The improvement of institutions necessarily entails strengthening internal self-control mechanisms and ensuring that the final word always falls upon the collective, preserving legal certainty and harmony among the powers of the Republic.
