The term de facto, of Latin origin, designates a legal situation that, although lacking formal legitimacy or strict legal support, produces tangible effects in the real world. In Public and Private Law, this concept serves to protect legal certainty and good faith, granting validity to acts performed by agents or in contexts that, under the rigor of de jure norms, would be void, thereby ensuring the stability of social relations.
Concept and Foundation
The dichotomy between de facto (in fact) and de jure (by law) constitutes one of the pillars of general legal theory. While de jure refers to absolute compliance with established norms, de facto describes a situation that, despite formal irregularities, becomes consolidated in factual reality. The legal nature of this institute lies in protecting trust and preserving the continuity of public services and private relations, avoiding the normative chaos that would result from the indiscriminate annulment of acts performed by those who possess an appearance of legality.
Historical Origin and Evolution
Historically, the doctrine of the "de facto officer" dates back to Anglo-Saxon Law, consolidating itself as a pragmatic necessity to validate administrative acts performed by agents who, although not legally invested, acted under the appearance of legitimacy. In Brazilian Law, this doctrinal construction was adopted to mitigate the rigor of the principle of strict legality, allowing the public administration and the Judiciary to recognize legal effects in situations that, under a formalist analysis, would be non-existent.
Legal Provision and Framework
Although there is no "Code of Fact," the Brazilian legal system embraces the concept in several statutes:
- Federal Constitution (Art. 37): The theory of appearance and the protection of the good-faith administrator find resonance in the principles of efficiency and legal certainty.
- Law 9.784/1999 (Administrative Procedure Law): Establishes, in its Art. 2, sole paragraph, the prohibition of imposing disproportionate sanctions and the protection of the administered, supporting the validity of acts that did not cause direct harm to the public interest.
- Civil Code (Art. 113): The interpretation of legal transactions must consider objective good faith and customs, which are essential elements for the validation of de facto situations.
Practical Application and Jurisprudence
The jurisprudence of the Superior Courts (STF and STJ) has consolidated the application of this institute, especially in Administrative and Social Security Law:
The STF, when judging matters of general repercussion, has maintained the validity of acts performed by public servants who, although lacking regular investiture (for example, in cases of civil service examinations annulled after a long period), had their acts recognized to avoid the illicit enrichment of the administration and to protect third parties. The STJ, in turn, applies the Theory of Appearance to validate contracts entered into by those who, in the eyes of the public, held powers of representation, protecting the good-faith contractor.
Related Principles and Divergences
The de facto institute dialogues directly with the principles of Legal Certainty and Objective Good Faith. The main doctrinal divergence lies in the conflict between the primacy of strict legality and the need for the stabilization of relations. Formalist schools argue that recognizing effects for de facto acts weakens the Rule of Law; however, modern doctrine, influenced by authors such as Celso Antônio Bandeira de Mello, argues that absolute nullity must be relativized when the social cost of annulling the act outweighs the benefit of restoring strict legality.
Contemporary Relevance
In contemporary times, the application of this institute has expanded to Digital Law and International Law. In situations of regime transitions or systemic failures on digital platforms, the de facto doctrine allows for the maintenance of records and transactions that, without this safeguard, would paralyze economic and social flow. The practical impact is the mitigation of losses resulting from formal defects, ensuring that social reality prevails over bureaucratic rigidity when the error is not attributable to the citizen.
