The clash between ineligibility rules and the principle of presumption of innocence is perhaps the most sensitive point in contemporary electoral law. The issue is central because it defines who can or cannot run for election, directly affecting the legitimacy of the democratic process. 

While the legal system must protect administrative morality and the probity of public officials, it cannot be ignored that political rights are an essential part of citizenship and can only be restricted within constitutional limits.

The controversy took on decisive dimensions after the approval of Complementary Law No. 135 of 2010, known as the Clean Slate Law. This is because it tightened electoral rules and inaugurated a scenario in which the Electoral Court began to face increasingly complex situations, especially when ineligibility is applied to candidates who have not yet had a final criminal conviction. 

In this text, I want to analyze with you the constitutional foundations, the jurisprudential parameters, and the practical impacts of this discussion.

The nature of ineligibilities

Ineligibilities are limitations on passive electoral capacity, that is, the possibility of being voted for and holding elected office. 

As a general rule, ineligibilities are directly provided for in the Constitution, such as in Article 14, which deals with family ties, disqualifications, and the impossibility of reelection in certain circumstances, or they may be established by supplementary law, as authorized by paragraph 9 of the same article.

The legislator sought, through this, to create mechanisms to defend the normality and legitimacy of elections, preventing the influence of abuses of power and ensuring that the popular choice was not captured by interests contrary to the democratic regime. 

It is important to emphasize that, since its inception, legal doctrine has insisted that ineligibility should not be understood as a punishment, but as a preventive and protective measure. 

The presumption of innocence and its electoral limits.

Article 5, item LVII, of the Federal Constitution establishes that no one shall be considered guilty until a final and unappealable criminal conviction is issued. 

The principle of presumption of innocence is one of the pillars of the rule of law and serves to prevent citizens from being treated as guilty before the criminal process is concluded.

However, in the electoral arena, the application of this guarantee has undergone some changes. 

Since the Clean Slate Law, a collegial decision has been sufficient to deem candidates ineligible. In other words, restricting political rights no longer requires a final ruling.

The Supreme Federal Court was called upon to decide on the compatibility of this rule with the Constitution. 

In Declaratory Actions of Constitutionality 29 and 30, judged together with Direct Action of Unconstitutionality 4578, the Court decided that the law was constitutional. 

The justification was that the ineligibilities are not of a criminal nature, but electoral, and that their function is to protect values ​​of collective interest, such as administrative morality. 

In this way, the presumption of innocence was relativized in the name of protecting democracy.

The clash between ineligibility and the presumption of innocence takes concrete form in electoral proceedings, where procedural speed is an inescapable principle. This is not merely a requirement for efficiency, but a practical necessity: elections have fixed dates and predetermined terms, which demands swift responses from the Judiciary so that the democratic process maintains its legitimacy.

The candidate registration process

The initial moment to discuss ineligibilities is during the application for registration of candidacy. 

It is at this stage that the Action to Challenge the Candidate Registration (AIRC) is proposed, the deadline for which is only five days from the publication of the notice with the list of candidates. 

The jurisprudence of the TSE (Superior Electoral Court), crystallized in Precedent 45, allows the electoral judge to take cognizance ex officio of causes of ineligibility or the absence of a condition of eligibility, provided that the principles of adversarial proceedings and full defense are respected.

The assessment of eligibility conditions and causes of ineligibility must occur at the time of the registration request. 

However, the legal system allows for the consideration of supervening facts, whether factual or legal in nature, that are capable of removing the ineligibility. 

Appeal against the issuance of a diploma and constitutional ineligibility.

When the cause of ineligibility is of a constitutional nature or when it arises after registration but before the election, it can be challenged through an Appeal Against the Issuance of a Diploma (RCED). 

In this scenario, the declaration of ineligibility not only prevents the certification of election results, but also entails the loss of office for the person who had already been considered elected.

RCED, however, reveals a significant tension. 

Article 216 of the Electoral Code stipulates that, until a final decision is reached by the Superior Electoral Court, the elected official may serve their full term. 

This mechanism seeks to ensure institutional stability, preventing the constant turnover of public officials. 

But at the same time, it allows someone whose constitutional ineligibility is being discussed to fully exercise their mandate until a final decision is reached. 

The tension between stability and morality, in this context, is evident and demonstrates how the electoral process needs to deal with values ​​that are constantly clashing.

The discussion about ineligibility and the presumption of innocence finds fertile ground for critical reflection and strategic application in professional and academic practice. 

The postgraduate program in Electoral Law at IDP stands out as a privileged space for delving into sensitive topics and structuring technical responses that address the dilemmas of contemporary democracy.

The course curriculum was carefully designed to cover the main areas of Electoral Law, from Political Rights and Eligibility Requirements, Electoral Propaganda and Campaign Financing and Accountability, to more technically demanding subjects such as Electoral Judicial Litigation I and II, Appeals System and Enforcement, Electoral Crimes, Analysis of Electoral Jurisprudence, and Ineligibility and Candidate Registration.

This set of tools ensures that students not only understand the normative foundations, but also have the ability to apply this knowledge in formulating legal and political strategies for campaigns.

Another distinguishing feature of the program is its faculty, comprised of recognized authorities in the field of Electoral Law. 

Among the professors are names such as Walber Agra, PhD in Law and a leading figure in legal doctrine, Eduardo Borges, a lawyer with a distinguished career in electoral litigation, Roberto Martins, legislative consultant for the Chamber of Deputies, as well as professionals who hold strategic positions in the Electoral Court and in oversight bodies. 

Are you prepared to act strategically in election campaigns?

In fact, devising an election campaign strategy requires integrating the legal and political aspects. 

Investing in communication and vote-gathering is pointless if the candidacy is vulnerable to challenges or appeals against the issuance of diplomas. 

By offering subjects such as Digital Electoral Law and Electoral Compliance, the postgraduate program broadens the professional's perspective beyond the courtroom, allowing them to understand contemporary demands related to transparency, fake news, the use of social media, and crowdfunding.

Thus, academic study becomes a tool for practice: identifying legal risks of a candidacy, assessing the need for resignations from incompatible positions, structuring defenses in challenge actions, or even preventing accusations of abuse of political and economic power. 

In other words, postgraduate studies prepare not only lawyers, but also strategists capable of anticipating problems and offering legally sound solutions.

By combining theory and practice, the course reaffirms its commitment to training professionals who understand Brazilian democracy in all its complexity, prepared to defend legitimate candidacies and, above all, to strengthen the electoral process as a space of integrity and public trust.
