Lacy practiced law in Texas before moving to Virginia, serving for three years with the Texas Legislative Council, and then for three years with the Texas Attorney General's office, specializing in antitrust and
consumer protection law. From 1976 to 1977, Lacy moved to Virginia and served as legislative aide to state delegate
Carrington Williams. She then began working for the Virginia Office of Attorney General, under
Gerald L. Baliles. She rose to become the state Deputy Attorney General for Judicial Affairs (a division that prosecutes consumer protection violations, oversees the state's antitrust laws, state regulations and conflict of interest statutes). Governor
Charles S. Robb appointed her to the State Corporation Commission, which had judicial as well as responsibilities. She was the first woman on the SCC. After Gerald L. Baliles was elected Governor of Virginia, he appointed Lacy to the Virginia Supreme Court as discussed below. Delegate
Theodore V. Morrison Jr., a lawyer from
Newport News, Virginia and part-time member of the General Assembly, was nominated and confirmed to succeed her on the SCC. On November 22, 1988, Gov. Baliles appointed Lacy to the Virginia Supreme Court, and the General Assembly confirmed her appointment in due course. She was again the first woman to hold the position, and she was subsequently elected to a full 12-year term. Although by seniority she was the longest serving active member of the Supreme Court when Chief Justice
Harry L. Carrico retired, Lacy did not succeed him as chief justice. Although the chief justice was previously the senior active member of the Court, a change in the law before Chief Justice Carrico's retirement provided that in future the chief justice would be selected by an election of the Court members for a four-year term. Chief Justice
Leroy Rountree Hassell, Sr., then second in seniority to Justice Lacy, was elected chief justice, and was the first African American to hold that position. Justice Lacy retired and took senior status effective August 16, 2007. On December 31, 2019, Justice Lacy stepped down as a senior justice after more than 30 years' service to the Court. The
Library of Virginia honored her as one of the eight
Virginia Women in History for 2008. ==See also==
