This new filing (commissioner-public-lands-cert-petition) is an appeal of a New Mexico appellate court decision (here). The case also involves the Jicarilla Apache Nation, Navajo Nation, and Ute Mountain Ute Tribe.
Here is the question presented:
Whether the New Mexico Commissioner of Public Lands may claim federal reserved water rights with respect to lands Congress reserved from the federal public domain, and granted to the State of New Mexico subject to a strict, federally enforceable trust, to support public education and for other related purposes specified by Congress.
