Brazil’s president leads the federal executive and has significant authority over administration, legislation, foreign relations, the armed forces and federal budget proposals. The office is not unlimited: the 1988 Constitution assigns Congress roles in lawmaking, appointments, treaties and exceptional powers, and provides routes for presidential accountability and judicial review.
What is the president’s role in Brazil?
Brazil’s Constitution says the Executive Power is exercised by the president, assisted by the ministers of state (Article 76). The president heads the federal administration, while ministers help carry out executive responsibilities. The Supreme Federal Court’s constitutional portal likewise describes the president as head of the federal public administration, with ministers subordinate to the office.
That establishes the president’s formal constitutional authority. It does not by itself show how much political support a particular president can assemble in Congress or how effectively an incumbent can pursue an agenda.
What can the president do in the ordinary exercise of office?
Direct federal administration
The president has superior direction of the federal administration and can appoint and dismiss ministers. The president may issue decrees concerning the organization and functioning of the federal administration only within constitutional limits: such decrees cannot increase expenditure or create or abolish public bodies. A decree may abolish vacant functions or positions.

Influence legislation and veto bills
The president may introduce bills in areas specified by the Constitution, sanction and promulgate bills passed by Congress, and veto a bill in whole or in part. A veto must be issued within 15 working days and must be based on unconstitutionality or conflict with the public interest. It is not an absolute veto: Congress can reject it by an absolute majority of deputies and senators. The current consolidated Constitution, including Articles 84 and 66, sets out these powers and limits.
Issue provisional measures
In cases of relevance and urgency, the president may adopt a provisional measure with force of law and must submit it immediately to Congress. It generally loses effect unless Congress converts it into law within 60 days; that period may be extended once for an equal period. The Constitution bars provisional measures on several subjects, including criminal and electoral matters, matters reserved to complementary law, and certain budget matters. They are therefore a consequential but temporary and reviewable instrument, not a general substitute for legislation by Congress. See Article 62 of the Constitution.
Propose federal plans and budgets
The president submits the multi-year plan, the budget-guidelines bill and federal budget proposals to Congress, and presents annual accounts. This gives the executive a central role in planning and proposing federal spending; it does not let the president set the budget unilaterally.
Which powers are shared with or checked by other institutions?
| Area | Presidential authority | Constitutional check or shared role |
|---|---|---|
| Legislation | Initiates specified bills, sanctions and promulgates bills, and may veto all or part of a bill. | Congress considers legislation and may reject a veto by an absolute majority of deputies and senators. |
| Provisional measures | Adopts them in cases of relevance and urgency, with force of law. | They must be submitted immediately to Congress, face subject-matter restrictions and generally expire unless converted into law within 60 days, with one possible equal extension. |
| Treaties and international acts | Maintains relations with foreign states and accredits diplomatic representatives. | Treaties and international acts are subject to congressional approval. |
| Specified senior appointments | Makes appointments listed in the Constitution, including appointments to certain senior posts. | Some appointments, including ministers of the Supreme Federal Court and other higher courts, require Senate approval. |
| Exceptional security powers | May decree a state of defense, a state of siege or federal intervention; has constitutional responsibilities concerning declarations of war and peace. | The Constitution provides congressional roles, including authorization or approval of declarations of war and peace in the circumstances it specifies. |
| Federal plans and budgets | Submits planning and budget proposals and presents annual accounts. | Congress has a role in considering the proposals; the president’s proposal authority is not unilateral control of spending. |
The official English translation of the Constitution is available from the Chamber of Deputies. The precise procedures for exceptional security powers depend on the relevant constitutional provisions; listing the president’s authority does not mean those powers can be used without their prescribed safeguards.
What authority does the president have over foreign affairs and the armed forces?
The president maintains relations with foreign states, accredits diplomatic representatives and exercises supreme command of the Armed Forces. The president may appoint the commanders of the military services. These constitutional responsibilities coexist with congressional roles: treaties and international acts require congressional approval, and certain appointments require Senate approval. The Constitution also conditions declarations of war and peace on congressional authorization or approval in the situations it specifies.
How can the president be held accountable?
Articles 85 and 86 of the Constitution identify grounds for presidential responsibility and set out accusation and trial routes. After approval by two-thirds of the Chamber of Deputies, a common-crime case goes to the Supreme Federal Court, while a responsibility-crime case goes to the Senate. These constitutional procedures, alongside judicial review and Congress’s legislative powers, are part of the limits on the office.

The president has substantial formal powers, especially in directing federal administration and shaping the legislative agenda. But powers differ in how they operate: some are exercised by the president within defined limits, while others require congressional participation or approval. A legal power to propose, appoint or issue a measure does not guarantee that the president can secure a preferred political outcome.
