<h1>Indigenous groups allege hydrocarbon auction violates rights by proposing exploration on Indigenous lands without free, prior and informed consent</h1> Several Indigenous groups in the Amazon allege a government hydrocarbon plan to auction 49 oil and gas blocks worth about USD 47 billion unlawfully infringes their constitutional and international rights by proposing exploration on territory overlapping Indigenous lands without free, prior and informed consent. They contend prior court rulings and required consultations were ignored; the government asserts existing consultations and legal frameworks suffice. Legal disputes may invoke constitutional protections, consultation jurisprudence, environmental and conservation statutes, and obligations under international law, while recent legislative and executive changes and a contested referendum heighten risks of litigation, injunctions, protests and international scrutiny.
