An administrative act must meet the validity requirements set by law. When one of those requirements is defective, the act may be annulled or convalidated (corrected), depending on the nature of the defect.

What an administrative act is and what it requires

An administrative act is any unilateral expression of will by the Public Administration, acting in that capacity, whose immediate purpose is to acquire, protect, transfer, modify, extinguish or declare rights, or to impose obligations on private individuals or on the Administration itself. This classic definition covers everything from appointing a public employee to issuing a building permit.

Classic Brazilian administrative-law scholarship, consolidated in the work of Hely Lopes Meirelles, identifies five validity requirements for an administrative act: competence, purpose, form, motive, and object. These requirements are the structural elements of the act, and the absence or defect of any one of them can undermine its legal validity.

Competence is the legal authority granted to the public official to perform the act. The official must be lawfully invested in the position and must act within the limits of that authority. Competence cannot be waived, does not lapse with time, and cannot be transferred, except in cases of delegation and evocation (a superior taking over a matter) provided for by law.

Purpose is the public-interest goal the act must achieve. Every administrative act must serve the public interest, or it amounts to misuse of purpose (abuse of power), one of the most serious forms of administrative illegality. Purpose may be general, when it refers to the public interest in a broad sense, or specific, when the law sets a particular objective for that type of act.

Form, motive, and object: completing the structure of the act

Form is the way the act is expressed. As a rule, administrative acts must be written, reasoned, and published in an official outlet. Law 9.784/1999, which governs administrative proceedings at the federal level, provides in Article 22 that the acts of an administrative proceeding do not require any particular form unless the law expressly demands one. Specific forms may nevertheless be required for certain acts, such as the ordinance, the decree, the resolution, and the permit.

Motive is the factual and legal situation that justifies the act. The statement of reasons, which sets out the motives, is a requirement of transparency and oversight of administrative acts. The theory of determining motives, widely accepted by the courts, holds that once the motives for an act are stated, the Administration is bound by them. If the stated motives are false or nonexistent, the act is invalid.

The object, also called the content, is the immediate legal effect the act produces. The object must be lawful, possible, determined or determinable, and moral. An act whose object is unlawful, impossible, or indeterminable is considered void. For example, appointing a candidate who failed a public-service examination has an unlawful object because it violates the merit principle.

These requirements are the structural elements of the act, and the absence or defect of any one of them can undermine its legal validity.

The distinction between bound acts and discretionary acts is directly tied to the validity requirements. In bound acts, the law predetermines every requirement, leaving the administrator no room to choose. In discretionary acts, the law gives the administrator freedom to assess the motive and choose the object based on expediency and timing, within the limits of the law.

Defects in administrative acts and their consequences

Defects in administrative acts can be classified as curable or incurable. Curable defects can be convalidated by the Administration itself, while incurable defects necessarily lead to annulment of the act. This distinction has significant practical importance because it determines the legal treatment that applies.

A defect of competence is generally curable unless the competence is exclusive. Ratification of the act by the competent authority fixes the defect and makes the act valid from the moment it was originally performed. However, when the act is performed by an authority that is entirely without competence, the defect is incurable and the act must be annulled.

A defect of purpose, known as abuse of power or misuse of purpose, is always incurable. It occurs when the official acts out of personal interest, to favor third parties, or for any goal other than the public interest set out in the law. Transferring a public employee as a disguised punishment is a classic example of misuse of purpose.

A defect of form is curable when the form is not essential to the act’s validity. Acts performed without the form prescribed by law can be convalidated if the required form is not substantive in nature. However, when the law sets a specific form as a condition of validity, failing to follow it makes the act void.

A defect of motive, when the stated motives are false or nonexistent, makes the act incurable. The theory of determining motives binds the Administration to the motives it stated, and the falsity of those motives invalidates the act. A defect of object occurs when the content of the act is unlawful, impossible, or indeterminable, and it is likewise incurable.

Annulment, revocation, and convalidation

Annulment is the withdrawal of an administrative act because it is illegal. It may be carried out by the Administration itself, in the exercise of its self-review power recognized in Summaries (Súmulas) 346 and 473 of the STF (Brazil’s Supreme Federal Court), or by the courts when a case is brought before them. Annulment has retroactive effect: it undoes the act from its origin and reverses all the effects it produced.

Revocation, unlike annulment, applies to lawful acts that have become inconvenient or untimely. Only the Administration may revoke its own acts; the courts may not. Revocation has prospective effect, preserving the effects the act produced up to the date of revocation.

Convalidation, provided for in Article 55 of Law 9.784/1999, is the administrative act by which the Administration corrects the curable defects of an earlier act, making it valid from the beginning. The requirements for convalidation are the existence of a curable defect, no harm to third parties, and no injury to the public interest.

When an administrative act affects your rights and you spot possible defects in its validity requirements, seek specialized legal guidance. A review by a lawyer experienced in administrative law can reveal illegalities that support a request for administrative or judicial annulment.

Frequently Asked Questions

Can the Administration annul an act after a long time?

Law 9.784/1999 sets a five-year forfeiture period for the Administration to annul administrative acts that produce favorable effects for beneficiaries acting in good faith, unless bad faith is proven. After that period, the act becomes final and can no longer be annulled administratively. This period exists to protect legal certainty and the legitimate expectations of the people affected.

What is misuse of purpose, and how can it be proven?

Misuse of purpose occurs when a public official performs an act for an aim other than the one the law provides. Proof is often indirect, drawn from indications and circumstances that reveal the official’s real motivation. Examples include punitive transfers, dismissals out of personal revenge, and rigged bidding. Evidence may be documentary, testimonial, or circumstantial, and the courts allow the burden of proof to shift in cases that are hard to prove.

What is the difference between a void act and a voidable act in administrative law?

A void act has an incurable defect that affects essential elements such as purpose, motive, or an unlawful object, and it cannot be convalidated under any circumstances. A voidable act has a curable defect, usually in its competence or form, and the Administration may convalidate it. In practice, the immediate consequence is the same, since both can be declared invalid, but a voidable act offers the chance to correct it before it is declared void.
