What this is
Cooper v. Roberts decided who owned a copper-bearing section sixteen in Michigan’s Upper Peninsula. Justice John A. Campbell delivered the opinion of the Court. The plaintiff sued in ejectment, holding under a Michigan patent issued in 1851 to Alfred Williams; the defendant was a tenant in possession claiming through a federal mineral license and a patent issued in the same district. The Court held that Michigan was admitted to the Union “with the unalterable condition” that section sixteen in every township be granted to the State for the use of schools; that until the township is surveyed and the specific section designated, “the right of the State rests in compact”; and that when the political authorities perform that act, the State’s jus ad rem “becomes a jus in re, judicial in its nature, and under the cognizance and protection of the judicial authorities.” The mineral-lands act of March 1, 1847 did not withdraw the school sections from that compact. Judgment reversed, cause remanded.
Two things the opinion does not say are as important to a reader as what it does. It does not hold that the trust purpose limits the State’s power to sell: in the same passage that supplies the famous phrase, the Court said the power of the State over the subject is “plenary and exclusive,” that the grant “is to the State directly, without limitation of its power,” and that “it was competent to Michigan to sell the school reservations without the consent of congress.” And it is not the first Supreme Court decision to treat a federal education grant as a trust - Trustees of Vincennes University v. Indiana, 55 U.S. (14 How.) 268 (1852), decided three years earlier, is in this collection and reaches that ground first.
Why the Library cites it
Cooper is where the compact reading of the school-section grant is set down: the arrangement binds both sovereigns, it attaches to identified land once the survey identifies it, and the State’s acceptance of the benefit carries “a sacred obligation imposed on its public faith.” The argument in Stewards of the Republic that the section-sixteen reservation set the architectural template for every later school-trust grant runs through this opinion, and Schools of the Republic cites it at the doctrinal floor of its trust-law argument.
It is also the case that shows why the Library does not treat a single sentence as a holding. The Supreme Court has read Cooper on both sides of the trust question. Beecher v. Wetherby, 95 U.S. 517, 524 (1877) (Field, J.), construing Wisconsin’s parallel clause, read Cooper as holding “that by it the State acquired such an interest in every section 16 that her title became perfect so soon as the section in any township was designated by the survey.” Papasan v. Allain, 478 U.S. 265 (1986), collected Cooper on the fee side of its unresolved footnote-18 survey and read it as a case in which “the Court approved the sale of school lands granted to the State of Michigan even where Congress had not expressly authorized such a sale.” Alabama v. Schmidt, 232 U.S. 168 (1914) (Holmes, J.), quoted Cooper’s “sacred obligation” line and held the obligation “honorary.” A reader who needs the state-as-trustee proposition should take it from authorities that hold it, not from this one.
A representative holding - and a correction
Corrected September 17, 2026. An earlier version of this entry named Justice John Catron as the author of the opinion and introduced two passages as coming “from Justice Catron’s opinion.” The opinion is Justice John A. Campbell’s, for the Court. Neither passage appears in it. The sentence “The State has accepted these benefits, and is bound to administer the trust with fidelity” occurs nowhere in the opinion - the word fidelity does not appear in it at all - and the sentence beginning “The sixteenth section was set apart by Congress” is likewise not in the text; the opinion refers throughout to “section No. 16.” The lead-in “We agree with the Supreme Court of Michigan that” was attached to the “sacred obligation” clause, which the opinion states without it. The same earlier version said the Court held “that the trust purpose constrained the state’s authority to dispose of the land,” which is the opposite of what the passage holds. Read against the full opinion held in the Library’s collection, September 17, 2026.
What the opinion does say, at *181-82:
The trusts created by these compacts relate to a subject certainly of universal interest, but of municipal concern, over which the power of the State is plenary and exclusive. In the present instance, the grant is to the State directly, without limitation of its power, though there is a sacred obligation imposed on its public faith. We think it was competent to Michigan to sell the school reservations without the consent of congress.
And on when the State’s right becomes a title, at *179 - the passage the Court quoted back, word for word, in Beecher v. Wetherby, 95 U.S. at 524:
We agree, that, until the survey of the township and the designation of the specific section, the right of the State rests in compact, - binding, it is true, the public faith, and dependent for execution upon the political authorities. Courts of justice have no authority to mark out and define the land which shall be subject to the grant. But when the political authorities have performed this duty, the compact has an object, upon which it can attach, and if there is no legal impediment the title of the State becomes a legal title.
On the text. The 1855 reporter scan the Library holds carries heavy OCR damage. Both passages above are printed as later Supreme Court opinions in this collection print them - Beecher quotes the *179 passage in full at 95 U.S. 524, Papasan quotes the *181-82 sentence in its footnote 18, at 478 U.S. 289, and Schmidt quotes the “sacred obligation” clause at 232 U.S. 173-74 - so that no scanning artifact is passed off as the reporter. Anyone quoting for filing should read the official 18 How. 173.
On the year. The case was decided at the December Term 1855 and entered as filed January 29, 1856. The Library cites it as (1855), after the term; the Supreme Court itself cites it as (1856) - Andrus v. Utah, 446 U.S. 500, 523 (1980) (Powell, J., dissenting), and Papasan, 478 U.S. at 279-80. Both forms name the same case.
