In the Brazilian legal system, the injunction is fundamentally embodied in the Mandado de Injunção (Writ of Injunction), a constitutional procedural instrument designed to address legislative omissions that prevent the exercise of constitutional rights and freedoms, as well as prerogatives inherent to nationality, sovereignty, and citizenship.
Concept and Foundation
The institute of the injunction, under the aegis of Brazilian Constitutional Law, finds its genesis in the need to provide effectiveness to norms of limited efficacy when the legislator's inertia hinders the enjoyment of fundamental rights. The legal nature of the Mandado de Injunção is that of a special constitutional action aimed at controlling unconstitutional omission, seeking not only to declare the legislator in default but, nowadays, to concretize the claimed right.
Historically, the institute evolved from a stance of "non-cognizability" or mere declaration of unconstitutionality by omission to a stance of concretization, as crystallized in the jurisprudence of the Supreme Federal Court (STF). Overcoming the non-concretist theory, which limited the Judiciary's role to a simple warning to the Legislative Branch, marks a paradigmatic shift in the interpretation of Art. 5, LXXI, of the 1988 Federal Constitution.
Origin and Doctrinal Evolution
Classical doctrine, led by authors such as José Afonso da Silva and Celso Antônio Bandeira de Mello, has always highlighted that legislative inertia cannot serve as a pretext for annulling the constitutional normative content. The evolution of the STF's understanding, culminating in the judgments of Mandados de Injunção 670, 708, and 712, consolidated the adoption of the concretist position, allowing the Judiciary to establish conditions for the exercise of the right or to apply, by analogy, related norms until the legislator fills the gap.
Legal Provision and Normative Structure
The Mandado de Injunção has direct foundation in the 1988 Federal Constitution, in its article 5, item LXXI, which states: "a writ of injunction shall be granted whenever the lack of a regulatory norm makes it unfeasible to exercise constitutional rights and freedoms and the prerogatives inherent to nationality, sovereignty, and citizenship". Procedural regulation, in turn, was consolidated by Law No. 13.300/2016, which disciplined the rite, the standing parties, and the effects of the decision.
Practical Application and Current Jurisprudence
The practical application of the institute is vast, notably in matters involving social rights, such as the right to strike for public servants (Art. 37, VII, CF/88) and special retirement (Art. 40, § 4, CF/88). The STF, through Law 13.300/2016, solidified the possibility for the magistrate to set a deadline for the issuance of the missing norm and, in specific cases, to determine the application of norms from analogous regimes.
Current jurisprudence reflects the maturity of the institute, dismissing any claim of violation of the principle of separation of powers (Art. 2, CF/88). The Judiciary, when issuing a decision in an injunction case, does not usurp the legislative function but exercises control over the constitutionality of the omission, ensuring the supremacy of the Constitution.
Related Principles and Divergences
The debate revolves around the tension between the principle of separation of powers and the principle of maximum effectiveness of constitutional norms. Minority currents still maintain the need for strict observance of the reservation of law; however, the majority doctrine and dominant jurisprudence recognize the Mandado de Injunção as an essential instrument for the integrity of the constitutional order, preventing legislative silence from reducing the Constitution to a charter of intentions devoid of normative force.
Contemporary Relevance
The contemporary relevance of the injunction lies in its ability to act as a safety valve for the democratic system in the face of legislative paralysis. In times of heightened polarization, where fundamental rights agendas may face procedural blocks in the National Congress, the Mandado de Injunção remains the definitive mechanism to ensure that omission does not turn into the suppression of rights.
