September of that year, the Costa Rican Constitutional Court ruled in ADELA's favor, and granted an annulment of the four-block HCRH concession. The Court's ruling was based on International Labor Organization Convention 169, "Concerning Indigenous and Tribal Peoples in Independent Countries," to which Costa Rica is bound. The Court later modified the ruling in November 2000, however, and nullified only those blocks affecting indigenous territory. In September 2001, SETENA convened a public hearing in Limón to debate issues concerning oil development. HCHR bused in approximately 100 people who they paid to attend the hearing, yet they were outnumbered by ADELA members. More than 300 people are reported to have supported ADELA's campaign with banners and posters. In addition, marine biologists and environmental organizations who support ADELA gave presentations about various social, economic, and environmental adverse impacts that could result from oil exploration and drilling. On February 28, 2002, SETENA rejected HCRH's EIA as not being environmentally or socially viable, and SETENA listed 50 reasons for its decision. HCRH's appeal was rejected by Elizabeth Odio, then-Costa Rican Minister of the Environment. In 2005, the Costa Rican President notified HCHR that their contract had been terminated, due to HCHR's failure to obtain an approved EIA pursuant to Costa Rican environmental law.
