Diarmuid Fionntain O'Scannlain (/ / DEER-mid oh-SKAN-lən; born March 28, 1937) is a Senior United States Circuit Judge of the United States Court of Appeals for the Ninth Circuit. His chambers are located in Portland, Oregon.
Born in New York City, New York, O'Scannlain received a Bachelor of Arts degree from St. John's University in 1957, a Juris Doctor from Harvard Law School in 1963, and a Master of Laws from the University of Virginia School of Law in 1992. He was in the United States Army Reserve, JAG Corps from 1955 to 1978.
In September 1960, O'Scannlain attended the founding conference of Young Americans for Freedom, held at William F. Buckley, Jr.'s estate in Sharon, Connecticut. At that conference O'Scannlain was elected to serve on YAF's original Board of Directors.
He was a tax attorney for the Standard Oil Company of New Jersey and New York City from 1963 to 1965, and in private practice in Portland, Oregon from 1965 to 1969. He was a deputy state attorney general of Oregon State Department of Justice from 1969 to 1971, then an Oregon public utility commissioner from 1971 to 1973, and finally Director of the Oregon Department of Environmental Quality from 1973 to 1974.
Run for Congress
In 1974, O'Scannlain was the Republican candidate for the United States House of Representatives representing Oregon's 1st congressional district, but lost to Democrat Les AuCoin, the first time the district had ever elected a Democrat.
He returned to private practice in Portland from 1975 to 1986, also working as a consultant to the Office of the President-Elect of the United States from 1980 to 1981, and as a team leader for the President's Private Sector Survey on Cost Control ("Grace Commission") from 1982 to 1983. He chaired an advisory panel for the United States Secretary of Energy from 1983 to 1985.
Federal judicial service
On August 11, 1986, President Ronald Reagan nominated O'Scannlain to a seat on the United States Court of Appeals for the Ninth Circuit vacated by Judge Robert Boochever. O'Scannlain was confirmed by the United States Senate on September 25, 1986, and received his commission on September 26, 1986. He took senior status on December 31, 2016.
O'Scannlain is a strong supporter of splitting the Ninth Circuit.
In a controversial March 2010 case, O'Scannlain joined the majority opinion that Seattle police officers did not employ excessive force when they tasered a pregnant woman. He was joined by Judge Cynthia Holcomb Hall in a contested 2–1 decision (judge Marsha Berzon dissented).
On February 13, 2014, O'Scannlain wrote the opinion for the majority in the case of Peruta v. San Diego, and issued a ruling that stated California's may-issue concealed carry rules, as implemented by the County of San Diego, in combination with a ban on open carry in most areas of the state, violate the Second Amendment, because they together deny law-abiding citizens the right to bear arms in public for the lawful purpose of self-defense. Consuelo María Callahan joined him in the majority, while Sidney Runyan Thomas dissented.
