According to this report by Staci Matlock in the Santa Fe New Mexican, the Court of Appeals heard oral argument in a case brought by a teenager, Akilah Sanders-Reed, asking the Court to hold that the “public trust” doctrine requires the New Mexico government to regulate greenhouse gases.
Ms. Sanders-Reed’s claims were rejected by the district court on the ground that the State’s ordinary regulatory process is where greenhouse gas regulations should be enacted, if at all.
The case is captioned Sanders-Reed v. Susana Martinez, and the Court’s oral argument notice states that this case will be decided by Judges Michael Vigil, Timothy Garcia, and Miles Hanisee.
