Alterações na lei de improbidade administrativa: Uma análise comparativa envolvendo a legislação anterior

Abstract

This article analyzes corruption in Brazil as a historical and persistent phenomenon, from the colonial period to contemporary scandals such as Operation Car Wash (Operação Lava Jato). In the national legal context, the corruption of public officials is characterized as an act of administrative misconduct, subject to the sanctions established by the Federal Constitution of 1988 and Law No. 8.429/1992 (Administrative Improbity Law – LIA). The study focuses on the changes introduced to the LIA by Law No. 14.230/2021 and their potential impact on the effectiveness of combating corruption in public administration. The main objective is to evaluate these modifications and their practical and legal effects, highlighting the importance of ethics and transparency in public management. The methodology adopted is qualitative, exploratory, and descriptive in nature, based on bibliographical research of renowned authors and documentary research, with particular attention to Brazilian legislation, especially the LIA before and after the enactment of Law No. 14,230/2021. Furthermore, recent decisions from the Federal Supreme Court (STF) and the Superior Court of Justice (STJ) were analyzed to understand the application of the new legislation and the consolidated jurisprudential interpretations
