On April 15, 2026, Brazil’s Supreme Federal Court resumed its judgment on whether it is constitutional to appoint relatives to political offices. The same session also addressed the limits of broad orders lifting bank and tax secrecy issued by investigative authorities.

What the Court Decided at the April 15 Session

The full-court session of the Supreme Federal Court (Supremo Tribunal Federal) focused on two issues of major institutional importance. The first was whether Binding Precedent 13 (Súmula Vinculante 13), which prohibits nepotism in public administration, also reaches offices of a political nature, such as cabinet ministers and state and municipal secretaries. The second was how far oversight and investigative bodies may go in demanding bank and tax records without prior court authorization.

The dispute over nepotism in political offices is not new, but it returned to the center of the debate after recent appointments reignited the argument over how the rule should be interpreted. The Court was asked to decide whether the prohibition applies without exception or whether there are exceptions based on the trust-based nature of a political office.

On the lifting of secrecy, the discussion centered on the balance between the State’s power to investigate and the constitutional protection of privacy and private life under Article 5, items X and XII, of the Federal Constitution.

Nepotism in Political Offices: The Core of the Disagreement

Binding Precedent 13 prohibits appointing a spouse, partner, or relative (in the direct line, collateral line, or by marriage) up to the third degree to a commissioned position or a position of trust. The dispute turns on an express carve-out, developed through case law, under which offices of a political nature fall outside that scope.

Those who favor broad application argue that administrative morality, a principle set out in Article 37 of the Constitution, does not allow a distinction between technical and political offices when what is at stake is impartiality and the ban on favoring a public official’s relatives. From this perspective, allowing political appointments of relatives defeats the very purpose of the precedent.

Those who favor keeping the exception argue that a political office results from the discretionary choice of the head of the Executive Branch, based on ideological affinity and shared responsibility for governing. On this view, political trust is a legitimate criterion, and any abuse should be addressed as administrative misconduct (improbidade administrativa), not through a blanket ban on nepotism.

The votes cast so far suggest that the full Court is moving toward setting objective criteria, possibly requiring proof that the appointee is technically qualified for the office and is not directly subordinate to the relative who made the appointment. The Court has also considered limiting the temporal effects of its ruling in order to preserve situations that are already settled.

On this view, political trust is a legitimate criterion, and any abuse should be addressed as administrative misconduct, not through a blanket ban on nepotism.

Bank and Tax Secrecy: Limits on Direct Requests

On the second issue, the Court again debated whether bodies such as the Federal Revenue Service (Receita Federal), the Public Prosecutor’s Office (Ministério Público), and audit courts (tribunais de contas) may obtain confidential data without a prior court order. In earlier precedents, the Court had already held that sharing information among tax authorities is legitimate, as long as confidentiality is preserved at both the source and the destination.

The question now is about cases in which a request goes beyond that scenario and amounts to a broad lifting of secrecy, with large volumes of data transferred without any specific investigative focus. Justices noted that generic requests, which do not identify the specific fact under investigation, come close to an improper fishing expedition and are incompatible with the constitutional system protecting privacy.

Some votes took the opposing view: effective enforcement against tax evasion, money laundering, and corruption requires flexible access to data, and without it oversight bodies could not do their work. An intermediate position that has gained traction would require an individualized justification, issued at the time of the request.

Practical Effects for Public Administration

The Court’s decision on nepotism in political offices will immediately affect federal, state, and municipal appointments, and it may trigger waves of review of administrative acts. Local decrees and laws on the subject will need to be brought into line with whichever interpretation prevails.

As for secrecy, clearer guidelines should reduce litigation over data requests and give both the people under investigation and the oversight bodies greater legal certainty. Administrative proceedings based on generic lifting of secrecy may be challenged, and evidence obtained in violation of the new parameters could be invalidated.

The judgment has not yet concluded. Requests to review the case file (pedidos de vista) and oral arguments are expected in upcoming sessions. Once the written decision (acórdão) is published, it is expected to contain a general repercussion thesis capable of guiding all levels of the Judiciary and public administration bodies.

Frequently Asked Questions

What does Binding Precedent 13 say about nepotism?

Binding Precedent 13 of the Supreme Federal Court prohibits appointing the spouse, partner, or relative of the appointing authority, whether in the direct line, collateral line, or by marriage, up to the third degree, to a commissioned position or a position of trust in direct and indirect public administration. The prohibition also covers cross-nepotism, in which two authorities appoint each other’s relatives.

Why is it controversial to apply the precedent to political offices?

The controversy stems from case law that placed political offices outside the direct reach of the precedent, on the grounds that these offices involve political trust and the discretionary choice of the head of the Executive Branch. Critics argue that this exception undermines administrative morality, especially when the appointment is not accompanied by proof that the relative is technically qualified for the role.

When may bank secrecy be lifted without a court order?

Case law allows confidential data to be shared among tax authorities, as long as confidentiality is preserved at both the source and the destination and the specific tax purpose is respected. Generic requests, without an individualized justification and without identifying the specific fact under investigation, tend to be held unconstitutional and must be submitted for prior court authorization.
