Chapter 5 presents the last two case studies of the book; this paired comparison completes the four sets. This pair of rulings has in common a lack of court-promoted monitoring mechanisms as well as the absence of legally empowered advocacy organizations. The first case study delves into the aftermath of the Chaco v. Defensor del Pueblo ruling in Argentina, where the Argentine Supreme Court sought to safeguard the rights of the Qom Indigenous group in the Chaco Province. The second case study is of T-231 1993, a ruling handed down by the Colombian Constitutional Court seeking to protect the right to a healthy environment for the inhabitants around the Bogotá Canal, in Cúcuta.
