Law No. 14.133 on Public Procurement and Administrative Contracts.

This Law establishes general rules for bidding and contracting for direct, municipal, and foundational public administrations of the Union, States, Federal District, and Municipalities, and covers: the bodies of the Legislative and Judicial Powers of the Union, States, and Federal District, and the bodies of the Legislative Power of the Municipalities, when performing administrative functions; special funds and other entities directly or indirectly controlled by the Public Administration. This Law does not cover public companies, mixed-capital companies and their subsidiaries, which are governed by Law No. 13.303 of 30 June 2016. Its primary objective is to establish a unified, modern, and efficient legal framework for public procurement and contracting within the direct, autarchic, and foundational Public Administration of the Union, States, Federal District, and Municipalities. The law aims to ensure the selection of the most advantageous proposal for the Administration considering not only immediate price but also the life cycle of the object, promoting efficiency, economicity, legality, transparency, and competition in all procurement procedures. It seeks to prevent overpricing, underpricing, fraud, and corruption, and sets clear rules for planning, tendering, contracting, execution, and control of public contracts. By doing so, the law strengthens governance, internal control mechanisms, and risk management practices across all phases of the procurement process.
Additionally, the law aims to foster innovation and sustainable national development, encouraging solutions that improve quality, technological advancement, and socio‑environmental responsibility in public contracts. It integrates principles such as equality among bidders, objective judgment, legal certainty, proportionality, and public interest. It also modernizes procurement by mandating digital processes, standardizing documentation, enabling integrated and semi‑integrated contracting regimes, incorporating environmental and social criteria, and emphasizing the rational use of public resources. By harmonizing procedures and broadening transparency through digital platforms like the PNCP, the law enhances accountability and public trust in government procurement.
