Here on the IDP Blog, we've already discussed some aspects of regulation in the Brazilian electricity sector and the reasons why it's a strategic field for your legal practice.
At this point, we will discuss Regulatory Law as a branch of law dedicated to the study and regulation of activities regulated by the Brazilian State.
So, what are its main characteristics? Are there different types of regulation in the national context? And furthermore, what is the role of regulatory agencies?
Come on!
Regulatory Law: A Growing Branch of Law
Regulatory law is responsible for establishing the rules and parameters for the operation of strategic sectors of the economy.
It encompasses the creation, implementation, and enforcement of rules and regulations that govern specific sectors of the economy. Examples include energy, telecommunications, transportation, health, and the environment.
Its main objective is to balance public interest with private interest and sustainable development, in pursuit of:
- to guarantee the provision of quality services to society;
- to promote fair competition;
- to protect consumer rights; and
- to ensure compliance with established public policies.
Regulatory law involves the analysis of laws, decrees, regulations, resolutions, and other rules applicable to the regulated sector.
It also covers issues related to the granting of licenses, authorizations, and permits for the operation of public services and specific economic activities.
Furthermore, some of the topics that this branch of law deals with include:
- rates, prices and quality of services;
- Obligations and rights of concessionaires;
- administrative sanctions;
- public consultation processes; and
- conflict resolution and arbitration.
In Brazil, there are different types of regulation.

Let's look at the main ones:
- Economic Regulation: It deals with the rules aimed at controlling economic aspects of regulated sectors, such as prices, tariffs, profit margins, subsidies, and financial incentives. This regulation seeks to ensure economic efficiency, promote competition, and prevent abuses of economic power.
- Technical Regulation: It refers to the technical and quality standards that establish guidelines and requirements for the provision of services or the production of goods in specific sectors. It aims to ensure the safety, quality, and efficiency of regulated activities.
- Sectoral Regulation: It is applied to specific sectors, such as electricity, telecommunications, transportation, health, water, and sanitation. Each sector may have particular characteristics and require specific regulation to ensure proper functioning and to meet the needs of society.
- Social RegulationThis involves regulating activities that directly impact society, such as education, health, food security, the environment, and consumer protection. This approach seeks to protect the rights of citizens and ensure the provision of essential services with quality and equity.
- Competition RegulationIts objective is to promote fair competition and prevent anti-competitive practices, such as abuse of dominant position, cartel formation, and market concentration. It seeks to guarantee free competition, stimulate innovation, and protect the interests of consumers.
These regulatory methods, however, can overlap or be combined, depending on the regulated sector and the specific needs of each area.
Regulatory agencies and the role they play.
In Brazil, regulation is carried out by regulatory agencies, which are federal or state autonomous entities, or even governmental bodies. They are created with the objective of regulating and overseeing certain strategic sectors of the economy, such as electricity, telecommunications, transportation, health, water, and sanitation.
They possess administrative, financial, and technical autonomy to perform their duties independently, within the limits established by law.
Some examples of Brazilian regulatory agencies are the National Telecommunications Agency (ANATEL) , the National Electric Energy Agency (ANEEL) , the National Land Transport Agency (ANTT) , and the National Health Surveillance Agency (ANVISA).
They play an important role in the implementation and monitoring of public policies in these areas, seeking to balance the public interest with the private interest.
Regulatory agencies have some fundamental characteristics.
One of them is autonomy . They possess administrative, financial, and technical independence, which gives them a certain impartiality in decision-making.
Furthermore, they have a normative function , meaning they can develop rules and regulations to guide the activities of the regulated sectors. These rules are established through regulatory instruments, such as resolutions and ordinances.
They also oversee the activities of regulated sectors, verifying compliance with established rules, contracts, and obligations.
Another characteristic of regulatory agencies is the granting of licenses, authorizations, and permits for the operation of public services and specific economic activities. They establish criteria and requirements for granting these licenses.
They can also act as mediators in resolving conflicts between regulated entities and between these entities and consumers, seeking consensual solutions.
We can include the promotion of competition in this list . This is because regulatory agencies promote fair competition in the regulated sectors, combating anti-competitive practices and stimulating competition among economic agents.
Finally, we mention social participation . They should promote the participation of civil society through mechanisms such as public hearings, consultations, and demonstrations – all in pursuit of transparency and legitimacy in decisions.
We must remember that regulatory agencies are created by law and have their own organizational structure, with directors appointed according to specific criteria, such as fixed terms and technical competence requirements.
This autonomy and technical expertise aim to guarantee a technical and independent performance in the regulation and oversight of the regulated sectors.

Regulation viewed from a contemporary perspective.
Carlos Eduardo Marques is a practicing lawyer in Public Law with an emphasis on Regulation and a student in the Professional Master's Program in Law at IDP , specializing in Private Law, Technology and Innovation.
According to him, regulation is currently being rethought.
"As a result, new debates have emerged regarding regulated self-regulation and the contemporary – and largely implemented – responsive regulation."
“Responsive regulation emerges within the Regulatory Agencies as a regulatory turning point,” he says. “It represents a redefinition of the entire regulatory logic previously adopted by them, which was based on command and control, in order to signal a change in perspective whose purpose is the effectiveness of regulation through close monitoring of the regulated entity, the establishment of creative solutions and incentives.”
But how should we devise such solutions or incentives? The legal expert and IDP student points to a tool that assists in informed decision-making, identifying alternatives, and improving the quality of regulations, known as Regulatory Assessment.
"In this way, Regulatory Assessment fits into this context as one of the most important instruments for the effectiveness of responsive regulation. This is because, through Regulatory Impact Analysis (RIA), it is possible to measure the impacts of the measure to be adopted on the regulated sector, and sectoral participation is indispensable in this process, as it can contribute with creative solutions when addressing the analysis."
Another tool that can be used is Regulatory Impact Analysis (RIA): "a mechanism designed to measure the effects of that measure in a specific scenario, using objective data about the effectiveness of the measure adopted".
But there is still a way to go, according to Marques:
"It is undeniable, therefore, that a structural change is occurring within the Regulatory Agencies, and this must be analyzed from the perspective of a new regulatory model. However, since this is a measure still in the implementation phase, much remains to be done and reviewed for the effectiveness of the responsive regulatory model."
And concludes:
"It is expected that, in the coming years, with the establishment of a cohesive agenda of Regulatory Outcomes Assessments (ROAs), the results obtained can serve as a basis for restructuring the rigid model of sectoral action still presented by the agencies."
