O'Hern served in the United States Navy from 1951 to 1954, during the Korean War, attaining the rank of Lieutenant, Junior Grade. After leaving active duty, he graduated from Harvard Law School in 1957, and served as a clerk to United States Supreme Court Justice William J. Brennan, Jr.[1]
He was an elected official in his hometown of Red Bank, serving on its borough council and as Mayor of Red Bank, New Jersey. Brendan Byrne, the Governor of New Jersey named O'Hern a commissioner of the New Jersey Department of Environmental Protection, and later as Counsel to the Governor. Byrne submitted his Supreme Court nomination to the New Jersey Senate, and he was confirmed on May 20, 1981, and sworn in on August 6, 1981.[1]
Judge O'Hern's opinion in State in the Interest of T. L. O. (1983) concerning administrative or teacher searches of public school students was reversed by the U.S. Supreme Court in New Jersey v. T. L. O. (1985).[2] [3]
He retired at age 70, and was replaced by James R. Zazzali.[4]
O'Hern and his wife Barbara have been residents of Little Silver, New Jersey.[1] They have a daughter.[5]
O'Hern died at age 78 on April 1, 2009, due to brain cancer at his home in Red Bank.[6]
O'Hern was noted for his "Sal's tavern" test, which suggested that if an opinion wouldn't make sense to the "gang" at Sal's Tavern in Red Bank, New Jersey it should be rewritten.[7]
The train station in Red Bank was named in his honor in November 2014.[8]
