Richard Patrick "Pat" DeWine is an American lawyer and an Associate Justice on the Ohio Supreme Court. He is the son of former U.S Senator and current Ohio Attorney General Mike DeWine. DeWine, like his father, is a Republican. 
DeWine recently served as a judge on the Ohio 1st District Court of Appeals. DeWine took his seat on the bench in January 2013 after defeating Bruce Whitman in the November 2012 general election. He won the Republican Party primary election in March 2016 for a seat on the Ohio Supreme Court commencing January 2, 2017. In November 2016 he won election to that seat over his Democratic opponent. Prior to his election as Judge he served as a Judge on the Hamilton County Court of Common Pleas and was an associate for 13 years with the firm of Keating Muething & Klekamp.
Previously DeWine served as a member of the Hamilton County Court of Common Pleas from 2009-2012, Hamilton County Commission and Cincinnati City Council. He was first elected in 1999, finishing sixth with 27,745 votes in a field of 20 (with the top nine elected), he was re-elected in 2001 (finishing second with 43,191 votes in a field of 26) and in 2003 (finishing sixth with 26,573 votes in a field of 26). He resigned from City Council in order to take his seat on the Hamilton County Commission. Chris Monzel, a Republican who had lost his council seat in the last election, was appointed to fill out DeWine's term on City Council.
DeWine was a candidate in the June 14, 2005 Republican primary for the Ohio's 2nd congressional district special election to the U.S. House of Representatives seat vacated by Rob Portman, who resigned to become U.S. Trade Representative. He placed fourth behind Jean Schmidt (who won the nomination and later the general election), Bob McEwen, and Tom Brinkman.
DeWine's marriage ended in divorce. He and his ex-wife have three sons.
