Facts. When Michigan was admitted to the Union in 1837, Congress’s enabling act granted to the new state section sixteen of every township for the use of public schools — the standard pattern descending from the Land Ordinance of 1785. Some of the section-sixteen lands within the surveyed townships of Michigan turned out to contain valuable mineral deposits. Cooper, claiming under a mineral location predating Michigan’s selection, sought to defeat the state’s title to a particular section-sixteen tract. The case reached the Supreme Court on the question whether the federal grant to the state, made at the moment of admission, conveyed a present and perfect title to the school sections, or whether the federal government retained a residual interest the state could not assert against an earlier locator.
Holding. The Supreme Court held that the section-sixteen grant vested in the state of Michigan at the moment of admission, as against any later claimant; that the state took the lands “upon the unalterable condition” that they be held and used for the support of schools; and that the federal-state compact created by the enabling act was binding on both sovereigns. The Court’s language treating the grant as an “unalterable condition” is the canonical nineteenth-century statement of the strict trust theory at admission — language quoted by every subsequent school-trust-lands opinion in the SCOTUS line.
Why it matters. Cooper is the doctrinal companion to Vincennes. Where Vincennes (1852) held that an earlier federal grant for educational purposes created a binding trust the state could not legislate away, Cooper (1855) held that the school-section grants made at statehood are similarly binding compacts whose terms govern the state’s conduct from the moment of admission forward. Together the two cases fix the federal-state compact theory of school-trust lands as a matter of federal supremacy: enabling acts are not aspirational, and the trust terms are not subject to unilateral revision by the state legislature. Cooper’s “unalterable condition” phrase is cited by Lassen, Andrus, Branson, and County of Skamania as the seventeenth-century-equity-into-American-public-law principle that animates the entire field.

Utah, 446 U.S. 500 (1980); and by the supreme courts of Michigan, Wisconsin, Minnesota, Washington, Idaho, Montana, Utah, Arizona, and other admission-era trust-lands states for the propositions that section-sixteen grants vest at admission, that the state takes as trustee on the terms of the federal compact, and that the trust terms are not subject to unilateral state modification.
