Cockrell served on the court until he was defeated in his third reelection campaign by Jefferson B. Browne in 1916.[1] He allegedly lost the election because an opinion he wrote that alienated railroad interests which then lobbied for Browne.[3] He lectured at the University of Florida College of Law from 1919 until 1940, and his students included Harold Sebring and Richard Ervin.[1]
He was on the losing side of a 3-2 decision on referendums that was passed by both the House and Senate in Florida but not signed.[4]
