The book analyses the obligation of municipalities to put out to tender the destination of domain assets in the face of the motivation of the administrative act, pointing out as an alternative the use of the discretionary power of the Administration, provided that it is based on motivation as an inspiration for social control. It also addresses the pertinence of arguing the unconstitutionality of the obligation to bid in court, by way of incidental control. Aimed at legal practitioners, political agents, public policy researchers, graduates in Administration, Law and related areas, professionals and institutions interested in public management, the book's singular message is the importance of popular participation in the drafting and implementation of public policies.
