Loss of profits constitutes a form of civil reparation belonging to the category of material damages, possessing the legal nature of patrimonial restoration. Within the scope of Civil Law and Labor Law, the institute aims to indemnify the victim for what they reasonably failed to earn as a result of an illicit act, observing the principle of full reparation.
Concept and Foundation
Loss of profits, technically termed lucrum cessans, represents the loss of the patrimonial increase that the injured party expected to obtain, frustrated by the unlawful conduct of another. It differs from consequential damages (damnum emergens) — which consist of the actual depletion of current assets — by projecting onto future wealth, provided that it is grounded in objective and concrete probability, rather than mere abstract conjectures.
Classical doctrine, based on authors such as Caio Mário da Silva Pereira and Agostinho Alvim, establishes that reparation should not serve as a source of unjust enrichment, but strictly as an instrument for restitution to the status quo ante. The core of applying this institute rests on the causality-probability binomial: the causal link must be direct and immediate, while the expectation of profit must be based on criteria of reasonableness.
Historical Origin and Evolution
The genesis of the institute dates back to Roman Law, specifically under the aegis of the Lex Aquilia, which established the foundations of extra-contractual civil liability. The evolution of the concept followed the transition from subjective liability to the increasing objectification of reparation, consolidating itself in modern Civil Codes as a vector of protection against illicit interference in economic activity and the labor capacity of individuals.
Legal Provision
In the Brazilian legal system, the normative basis is consolidated in the 2002 Civil Code:
- Art. 402: Establishes taxatively that "except for exceptions expressly provided by law, the losses and damages owed to the creditor include, in addition to what they effectively lost, what they reasonably failed to earn."
- Art. 403: Limits liability to the causal link, providing that "even if the non-performance results from the debtor's intent, losses and damages only include actual losses and loss of profits that are a direct and immediate effect thereof."
Practical Application and Jurisprudence
The jurisprudence of the Superior Courts (STJ and TST) has refined the application of loss of profits through rigorous benchmarks:
- STJ: The consolidated understanding is that loss of profits is not presumed; it requires conclusive proof of its occurrence. However, in cases of business activity stoppage, jurisprudence admits the presumption of damage when the suspension of the productive flow is demonstrated (Precedents: AgInt in AREsp 1,678,432/SP).
- TST: In the labor sphere, loss of profits is frequently discussed in indemnities for workplace accidents that reduce labor capacity, applying the principle of restitutio in integrum, pursuant to Art. 950 of the Civil Code.
Related Principles and Doctrinal Divergences
Contemporary debate revolves around the "loss of a chance" (perte d'une chance). Part of the doctrine argues that the loss of a real chance of gain is not strictly confused with loss of profits, but with the loss of the opportunity itself. While loss of profits requires the certainty of the frustrated gain, the loss of a chance admits a lower degree of certainty, focusing on the serious and real probability of success that was intercepted by the illicit act.
Contemporary Relevance
Currently, loss of profits assumes a critical role in complex litigation, such as environmental civil liability lawsuits, failures in global supply chains, and intellectual property violations. The complexity of modern damages imposes on magistrates the use of increasingly sophisticated accounting and econometric expert reports to quantify the expectation of profit, preventing the institute from becoming an instrument of legal speculation.
