It analyzes the historical development of consumer law and the role of Small Claims Courts in promoting swift and accessible justice, highlighting the importance of the principles of transparency, objective good faith and equity in consumer relations. The research uses a doctrinal and jurisprudential approach to demonstrate the effectiveness of tied selling as a tool to curb harmful practices and relieve the burden on the judicial system, promoting a fairer and more responsible business environment. It is concluded that the rigorous application of punitive damages contributes significantly to the protection of consumer rights, strengthening the civil liability system and social justice in Brazil.
