Who was Eugene Wambaugh?

Eugene Wambaugh was an American legal scholar. He was born on a farm near Brookville, Ohio to Rev. A. B. Wambaugh and Sarah Wells Wambaugh. He was educated at Harvard. Admitted to the Ohio bar in 1880, he practiced law in Cincinnati until 1889. He was professor of law at the State University of Iowa College of Law from 1889 to 92 and thenceforth at Harvard. In 1906-13 he was a member of the American Political Science Review, and in 1908-12 served as special attorney of the United States Bureau of Corporations. Several universities gave him the honorary degree of LL.D. His publications include:

⁕The Study of Cases

⁕Cases for Analysis

⁕A Selection of Cases on Agency

⁕Littleton's Tenures

⁕A Selection of Cases on Constitutional Law

Wambaugh was an adviser to the State Department on war problems in 1914 and was discharged honorably from the U.S. Army in 1919 with the rank of colonel. He retired from Harvard Law School in 1925.

Wambaugh devised the eponymous Wambaugh's Inversion Test, which provides that to determine whether a judicial statement in a common law case is ratio or obiter, you should invert the argument, that is to say, ask whether the decision would have been the different, had the statement is ommitted. If so, the statement is crucial and is ratio; whereas if it is not crucial, it is obiter.
