The article discusses the consequence of forming Metropolitan Regions due to population growth and the increased demand for services to implement minimum social rights. These regions do not adhere to traditional border limits, leading to a collision of fundamental rights and challenges of autonomy and responsibilities among municipalities. It argues that Metropolitan Regions should serve as spaces for the defense of social rights and human dignity. It proposes an interfederative governance system based on cooperative federalism to resolve the complex issues faced by municipalities in these regions. The responsibility for social rights, such as health, education, safety, and transportation, lies with each municipality, but the interdependence and integration in Metropolitan Regions demand a democratic and transparent governance structure. It concludes that democratic metropolitan governance, respecting the unique needs of each member, is necessary to ensure the fulfillment of social rights in Metropolitan Regions.
