When he defeated Republican State Representative John Porter by 650 votes in 1978, he joked to supporters that he had "won by a landslide." Porter won the seat after Mikva resigned to become a federal judge. Federal judicial service Mikva was nominated by President Jimmy Carter on May 29, 1979, to the United States Court of Appeals for the District of Columbia Circuit, to a new seat authorized by 92 Stat. 1629. Despite opposition from anti-gun control interests that spent over $1 million to oppose his nomination, Mikva was confirmed by the United States Senate on September 25, 1979 and received his commission on September 26, 1979. He served as Chief Judge from 1991 to 1994. His service terminated on September 19, 1994, due to retirement, after which he became White House Counsel to President Bill Clinton. During his 15 years as judge, including four as Chief Judge, Mikva used his experience in the legislative branch as well as with the conservative Justice Minton to craft his opinions.

In 1992, while serving as Chief Judge on the D.C. Circuit, Mikva appeared in the Kevin Kline comedy Dave as "Supreme Court Justice Abner J.

Future Obama appointee and United States Supreme Court Justice Elena Kagan did serve as one of Mikva's law clerks and was then a professor at the University of
