Tort Law in Brazil

Introduction

Tort law in Brazil (Direito da Responsabilidade Civil) governs the obligation to compensate for damages caused by wrongful conduct or dangerous activities. Codified primarily in the Brazilian Civil Code of 2002 (Articles 186-188, 927-954) and supplemented by the Consumer Protection Code (Law 8.078/1990) and other special legislation, Brazilian tort law incorporates both subjective liability (responsabilidade subjetiva, based on fault) and objective liability (responsabilidade objetiva, strict liability). The field has expanded significantly through judicial interpretation, particularly regarding non-pecuniary damages.

Fundamental Principles

Unlawful Act (Ato Ilícito)

Article 186 of the Civil Code defines the unlawful act as a voluntary act or omission that violates a right and causes damage to another, even if exclusively moral. Article 188 excludes unlawfulness for acts performed in: (i) legitimate self-defense; (ii) regular exercise of a right; and (iii) removal of danger (state of necessity).

General Clause of Civil Liability

Article 927 establishes a dual system: (i) the general rule requiring proof of fault for liability; and (ii) strict liability when the nature of the activity normally creates a risk of harm to others. This risk-based strict liability (responsabilidade pelo risco) is an innovation of the 2002 Code.

Subjective Liability

Elements

Subjective liability requires: (i) unlawful conduct (conduta ilícita); (ii) fault (culpa), including intent (dolo) and negligence (culpa stricto sensu); (iii) damage (dano); and (iv) causal link (nexo causal).

Fault

Fault is assessed objectively based on the standard of the reasonable person (homem médio). Degrees of fault — slight, ordinary, gross — affect liability, although Article 944 provides that compensation is measured by the extent of the damage, not the degree of fault.

Objective Liability

Strict Liability

Strict liability applies in several contexts: (i) activities that normally create risk (Article 927, sole paragraph); (ii) liability for damages caused by animals, buildings, and things; (iii) vicarious liability for damages caused by employees or agents (Article 932); and (iv) liability for defective products and services (Article 931).

Consumer Liability

The Consumer Protection Code (CDC) establishes strict liability for defective products (Article 12) and services (Article 14). The consumer need only prove the defect, damage, and causation; the supplier’s fault is presumed.

Environmental Liability

Law 6.938/1981 establishes strict liability for environmental damage, based on the risk theory (teoria do risco integral), with no defenses available except those proving that the damage did not result from the defendant’s activity.

Damage

Material Damages

Material damages (danos materiais) include: (i) actual damages (danos emergentes), the direct loss; and (ii) lost profits (lucros cessantes), what the victim would reasonably have earned. Damages are measured by the theory of direct and immediate causation (teoria dos danos diretos e imediatos).

Moral Damages

Moral damages (danos morais) compensate for non-pecuniary harm, including pain, suffering, reputational injury, and violation of personal rights. The STJ has established criteria for quantification: (i) the intensity of the suffering; (ii) the degree of fault; (iii) the economic capacity of the parties; and (iv) the social impact.

The STJ has recognized the possibility of punitive damages in cases of particularly reprehensible conduct, though Brazilian law does not have a formal punitive damages doctrine. The STF, in RE 884.569 (2021), with general repercussion (Theme 965), held that the Liability for Moral Damages in labor relations is not subject to a cap.

Aesthetic Damages

Aesthetic damages (danos estéticos) compensate for permanent physical disfigurement and are cumulative with moral damages (STJ, Resp 124.973).

Loss of a Chance

The loss of a chance (perda de uma chance) doctrine, recognized by the STJ, compensates for the loss of a probability of a favorable outcome, as in medical malpractice cases where the patient lost the chance of successful treatment.

Causation

Theories

Brazilian law adopts the theory of necessary causation (teoria da causalidade necessária or teoria do equivalente razoável), adapted from the French civil law, as the primary test of causation. The theory of adequate causation (teoria da causalidade adequada) is applied subsidiarily.

Multi-Causation

In cases of multiple causes, the STJ has applied proportionate liability, dividing responsibility among concurrent tortfeasors.

Vicarious Liability

Article 932 imposes vicarious liability on: (i) parents for minor children; (ii) guardians for wards; (iii) employers for employees; (iv) innkeepers for guests; and (v) educators for students. The principal is strictly liable for damages caused by its agents in the course of employment.

Defenses

Defenses to tort liability include: (i) exclusion of unlawfulness (self-defense, necessity, regular exercise of right); (ii) contributory negligence (culpa concorrente), reducing liability proportionally; (iii) exclusive fault of the victim; (iv) force majeure or act of God (caso fortuito ou força maior); and (v) prescription (three-year statute of limitations under Article 206, §3, V).

Special Liability Regimes

Traffic Accidents

Liability for traffic accidents is governed by the Civil Code (subjective) and the Brazilian Traffic Code (Law 9.503/1997), which imposes strict liability on vehicle owners.

Medical Liability

Medical liability is subjective (based on fault) for physicians (obligation of means) and objective for hospitals (as service providers under the CDC).

State Liability

Article 37, §6 of the Constitution establishes objective liability of the state for damages caused by its agents.

Conclusion

Brazilian tort law has evolved from a fault-based system to a sophisticated framework combining subjective and objective liability. The 2002 Civil Code’s introduction of risk-based liability and the expansion of moral damages have broadened protection for victims. The continued development of liability jurisprudence in areas such as medical malpractice, product liability, and environmental damage ensures that tort law remains a dynamic and responsive field.
