California Governor George Deukmejian appointed Lucas to be an
Associate Justice on the
Supreme Court of California in 1984. He replaced
Frank K. Richardson, former Governor
Ronald Reagan's only remaining appointee on the Court. In November 1986, Lucas was
retained by the voters by a wide margin. However, Chief Justice Bird and two other liberal justices were not. After Bird lost her retention election, Deukmejian announced on November 26, 1986, that he would elevate then-Associate Justice Lucas to the position of chief justice. Deukmejian then announced the appointment of three new conservative Associate Justices,
David Eagleson,
John Arguelles, and
Marcus Kaufman, thereby creating the first conservative majority on the Court in several decades. In matters of criminal law, the Lucas Court's interpretation of the law favored the government more than that of the Bird court. The Lucas court also reversed several pro-plaintiff landmark decisions in the context of tort law and insurance law. In September 1989, Chief Justice Lucas delivered the "State of the Judiciary" address to the
State Bar of California annual meeting in
San Diego, California. ==Personal life==
