Law, in its essence, is a science that strives for justice, and as a science it cannot be understood as an island. From this perspective, the interdisciplinary nature of legal science allows us to understand the law from a holistic viewpoint, suited to the social desires of a fair and equal society, which involves a society with a minimally stable economy and which values efficiency in the use of limited resources to satisfy unlimited needs. Therefore, the doctrine of Law and Economics, or what is known in Brazil as the Economic Analysis of Law, endeavours to incorporate economic concepts into legal science, making the appropriate methodological adjustments. What cannot be forgotten is that both law and economics play a leading role in building a fair, egalitarian society that seeks economic and social development. In other words, the law cannot be satisfied with the pursuit of formal justice alone, but must be guided by basic principles of efficiency and analysis of the impacts that judicial decisions have on the economic universe, avoiding economic collapse and legal insecurity.
