Thomas M. Cooley

In 1878, Cooley completed and published his work A Treatise on the Law of Torts or the Wrongs Which Arise Independently of Contract. One edition of Cooley's treatise on the subject matter of tort law was published in Chicago by Callaghan and Company in 1907. A Students' Edition was edited by John Lewis, a legal scholar and contemporary of Cooley. Lewis also wrote A Treatise on the Law of Eminent Domain. As a collegial work, Cooley's treatise on torts made extensive use of citations to case law.

Completed in March, 1880, while Dean of the University of Michigan, Cooley had published his treatise The General Principles of Constitutional Law in the United States of America. One edition of Cooley's treatise on the subject matter of Constitutional law was published in Boston by Little, Brown and Company in 1891. A Second Edition of the work was completed by a legal scholar and contemporary of Cooley's, Alexis C. Angell, in August, 1891. A third edition was published in Boston by Little, Brown and Company in 1898.

Cover of a modern edition of A Treatise on the Constitutional Limitations

In 1868 Cooley published A Treatise on the Constitutional Limitations Which Rest Upon the Legislative Power of the States of the American Union, in which he analysed the creation of state constitutions and the enactment of laws. It was probably the best-known legal treatise of its time.[8] By 1890, the sixth edition was printed.

Renowned Constitutional law scholar Edward S. Corwin wrote of the extranational judicial recognition (and, of course, that under the United States) of the implementation of, or concurrence with, Article IV, within which is the Full Faith and Credit Clause of the United States Constitution: "[i]n accordance with what is variously known as Conflict of Laws, Comity, or Private International Law, rights acquired under the laws or through the courts of one country may often receive recognition...in the courts of another country,[9] and it is the purpose of [U.S. Const., Art. IV, Sec. 1] to guarantee that this shall be the case among the States in certain instances." Corwin, or the editors of the 1978 Princeton University Press edition of The Constitution and What it Means Today thereinafter cited the Third Edition of Cooley's Principles of Constitutional Law.[10]

Corwin wrote, as to the Establishment Clause of the First Amendment of the United States Constitution (a clause contained within Amendment I), "[i]t [that Justice Story believed the United States Congress was still free to prefer the Christian religion over other religions, in contrast to modern Constitutional law and interpretation] is also supported by Cooley in his Principles of Constitutional Law, where it is said that the clause forbids 'the setting up of recognition of a state church of special favors and advantages which are denied to others.'"[11]

"This assumption," Robert G. McCloskey wrote as to the legal essentiality of the concept due process of law in The American Supreme Court, "was a product[,] no doubt[,] of many converging factors: the multiplication of 'welfare state' threats, the Macedonian cries of the business community and its legal and academic defenders, a growing awareness that an interpretation of due process[,] which seemed impossibly novel[—]and probably unnecessary a decade before[—]could be made acceptable by slow accretion[,] and might prove very useful in the cause of righteousness. As Waite wrote, the voices of two great contemporaries[,] Thomas M. Cooley and Stephen J. Field, must have been echoing in his mind. Cooley′s classic treatise[,] Constitutional Limitations, first published in 1868, had become a canonical text for jurists, and [Cooley's] support of due process in its emerging form gave the stamp of scholarly approval to an interpretation that seemed ethically more and more imperative."[12]

Corwin, or the editors of the 1978 Princeton University Press edition of The Constitution and What it Means Today, also cited Cooley in Constitutional Limitations.[13] As to Amendment I, as to Freedom of the Press in the United States, Corwin writes: [i]n about half of the State constitutions, our State courts ... [in reference to prevailing attitudes prior to the [American] Civil War, gradually wrote into the common law of the States the principle of "qualified privilege," which is a notification to plaintiffs in libel [law]suits that if they are unlucky enough to be office holders or office seekers, they must be prepared to shoulder the almost impossible burden of showing defendant's "special malice". Students of Constitutional law and Tort law will note this additional aspect of modern libel law as applied to legal issues intersecting the comments and comportment of public figures.

Within his treatise The General Principles of Constitutional Law in the United States of America, on the subject of municipal corporations, Cooley wrote:

It is axiomatic that the management of purely local affairs belongs to the people concerned, not only because of being their own affairs, but because they will best understand, and be most competent to manage them. The continued and permanent existence of local government is, therefore, assumed in all the state constitutions, and is a matter of constitutional right, even when not in terms expressly provided for. It would not be competent to dispense with it by statute.[14]
