Asarco Incorporated v. Kadish

The federal Enabling Act granted Arizona school lands subject to conditions requiring public auction and appraised-value sale, but excluded mineral lands; the later Jones Act extended those same grants to mineral lands, and an Arizona statute governing state mineral-land leases, including those to ASARCO (defendant) and other lessees, didn't require the Enabling Act's advertisement or appraisal conditions, prompting taxpayers (plaintiffs) to challenge the statute's validity.
