Dissertação (Mestrado Profissional em Direito Constitucional Econômico) - Centro Universitário Alves Faria, 2026.http://repositorio.unialfa.com.br/handle/123456789/765This dissertation analyzes the impacts of procedural delay in consumer disputes on the effectiveness of the constitutional principle of consumer protection, examining the interaction between substantive law, procedural law, and the institutional structure of the Judiciary within the context of the Brazilian economic order. It is based on the premise that consumer protection, elevated by the 1988 Federal Constitution to the status of a fundamental right and a principle of the economic order, is not limited to its normative dimension, but depends on the existence of effective and timely judicial protection for its realization. The research adopts a predominantly bibliographical approach, supported by jurisprudential analysis and empirical data derived from the “Justice in Numbers” reports issued by the National Council of Justice. Initially, the study examines the incorporation of consumer protection into the Economic Constitution, highlighting its structuring role in shaping the market and promoting balance in consumer relations. It then analyzes the principle of the reasonable duration of proceedings, its constitutional foundations, criteria for assessment, and its repercussions on economic activity, emphasizing that judicial efficiency is a relevant factor for legal certainty, institutional trust, and economic development. In this context, the study engages with international governance parameters, particularly the United Nations 2030 Agenda, with emphasis on Sustainable Development Goal 16, which advocates the promotion of effective, accountable, and inclusive institutions. This guideline demonstrates that the efficiency of the justice system is not limited to the procedural dimension but constitutes an essential requirement for the realization of fundamental rights and for the proper functioning of the economic order. Subsequently, the dissertation analyzes the main legal and structural challenges related to procedural delay in consumer disputes, with emphasis on mass litigation, the role of repeat players, evidentiary difficulties, and, above all, the inefficiency of the enforcement phase, identified as the main bottleneck of the justice system. Empirical data reveal the existence of a structural paradox, whereby the system shows a greater capacity to recognize rights than to enforce them, exposing a profound asymmetry between the adjudicative and enforcement stages. It is concluded that procedural delay undermines not only the effectiveness of consumer rights but also the economic order itself, by increasing transaction costs, expanding legal risks, and reducing the predictability of market relations. Therefore, the realization of the constitutional model of consumer protection requires the strengthening of institutional efficiency through the adoption of mechanisms aimed at rationalizing litigation, ensuring jurisprudential uniformity, and improving the effectiveness of the enforcement phase, in accordance with constitutional parameters and international guidelines for the promotion of effective institutions.ptMorosidade processualDefesa do consumidorOrdem econômicaDuração razoável do processo
