Understanding the difference between discretionary power and bound power is essential for anyone who deals with decisions made by the Public Administration. These two concepts define the limits of government action and determine when a public official is free to choose and when he or she must follow strictly what the law requires.

What Is Bound Power

Bound power (poder vinculado) exists when the law sets out every element of an administrative act and leaves the public official no room to choose. In that situation, the administrator simply checks whether the legal requirements are met and then performs the act exactly as the rule directs.

A classic example is the granting of an old-age retirement benefit by the INSS (Brazil’s National Social Security Institute). When an insured person proves that he or she has reached the minimum age and has the required contribution time, the INSS employee cannot deny the benefit for personal reasons or out of convenience. The law requires the benefit to be granted, and the administrative act is entirely bound to the legal requirements.

Under bound power, every element of the administrative act (competence, purpose, form, grounds, and object) is defined in advance by legislation. The public official acts as an executor of the legislature’s will, with no room for subjective judgment.

What Is Discretionary Power

Discretionary power (poder discricionário), by contrast, gives the public administrator some freedom to weigh the convenience and timing of performing a given act. That freedom is not absolute, however: it is always limited by the law and must serve the public interest.

When a mayor decides to build a school in a particular neighborhood, for example, he or she is exercising discretionary power. The law authorizes the construction of schools, but it does not say exactly where or when that must happen. The official assesses the needs of the population and makes the decision he or she considers most appropriate.

Discretionary power does not mean arbitrary power. The administrator’s freedom is limited by the law, by constitutional principles, and by the public interest.

It is worth noting that discretion applies especially to two elements of the administrative act: the grounds and the object. Competence, purpose, and form generally remain bound to the law even in discretionary acts.

Key Differences Between Discretionary and Bound Power

Here are the main points that distinguish these two ways in which the administration acts:

Under bound power, the administrator has no room to choose. Once the legal requirements are met, the act must be performed. Under discretionary power, there is a judgment of convenience and timing that lets the official decide whether to perform the act, when to do so, and what content to give it.

Judicial review also differs in important ways. Bound acts can be broadly reviewed by the courts, which check whether all legal requirements were met. With discretionary acts, judicial review addresses the legality of the act, but not its administrative merit. In other words, a judge may annul an unlawful discretionary act, but may not replace the administrator’s choice with his or her own.

As for stated reasons, both kinds of power require a justification. In a bound act, however, the justification consists of showing that the legal prerequisites were satisfied. In a discretionary act, besides the legal prerequisites, the administrator must also justify the convenience and timing of the decision.

Limits of Discretionary Power

It is important to understand that administrative discretion has clear limits. The first is the law itself: the administrator may act only within the space of freedom the rule grants. Any decision that goes beyond that space becomes unlawful.

The constitutional principles of the Public Administration (legality, impersonality, morality, publicity, and efficiency) work as permanent guideposts. A discretionary act that violates any of these principles may be annulled by the courts.

The doctrine of misuse of purpose (desvio de finalidade) is another important limit. When an administrator uses his or her margin of freedom to serve personal interests or those of third parties, rather than the public interest, the act is considered defective and may be annulled. Likewise, the doctrine of determining grounds (teoria dos motivos determinantes) holds that once the reasons for a discretionary act have been stated, the administrator is bound by them.

Why It Matters in Practice

Understanding the distinction between discretionary and bound power has significant practical consequences. When a person applies for a social security benefit and the request is denied, for example, knowing whether the act is bound or discretionary helps determine the strategy for challenging the administrative decision.

If the act is bound and all the requirements were proven, the denial is clearly unlawful and can be challenged both administratively and in court. If the act involves discretion, the challenge should focus on showing illegality, disproportionality, or misuse of purpose.

In either case, it is essential to have specialized legal guidance to assess the particulars of each situation. If you have questions about administrative acts that affect your rights, we recommend that you get in touch with a qualified professional.

Frequently Asked Questions

What is the main difference between discretionary power and bound power?

The main difference lies in the administrator’s margin of freedom. Under bound power, the law determines every aspect of the act and leaves the public official no choice. Under discretionary power, the law gives the administrator the freedom to weigh the convenience and timing of the decision, within legal limits.

Can the courts annul a discretionary act?

Yes. The courts may annul a discretionary act when they find illegality, misuse of purpose, violation of constitutional principles, or disproportionality. What the courts may not do is substitute the judge’s opinion for the merit of the administrative decision, as long as the act is lawful and reasonable.

Is the granting of INSS benefits a bound act or a discretionary act?

The granting of social security benefits is, as a rule, a bound act. When the insured person proves that all legal requirements have been met (age, contribution time, waiting period, and insured status), the INSS is obligated to grant the benefit. There is no room to weigh convenience or timing. For specific social security questions, consult a specialized attorney.
