Judge Austin LeCount Fickling, 62, of the D.C. Court of Appeals, died of cancer Sunday at the Washington Hospital Center.

During a long tenure that began in 1956 when he was appointed by President Eisenhower to be a judge of the old Municipal Court, now the Superior Court, he established a record for able and conscientious service.

Judge Fickling was held in such deep regard by lawyers who practiced before him as well as by his colleagues on the bench, that he was reappointed to that position in 1966 by President Johnson although he was a Republican and the Democrats were clamoring for a member of their own party to be given the position.

Two years later, his reputation for discharging his duties with dignity, ability and balance was still undiminished and President Johnson named him to the D.C. Court of Appeals.

Born in Washington, Judge Fickling graduated from Dunbar High School, attended Miner Teacher's College and received his law degree from the Terrell Law School here, where he later served as a professor.

He was admitted to the D.C. Bar in 1943 and to practice before the Supreme Court in 1947. He was in the private practice of law in Washington from 1943 until 1954, when he was appointed as assistant U.S. attorney.

During his tenure with the D.C. Court of Appeals, Judge Fickling was the court's liaison judge to the Organization Committee of the D.C. Bar, the Committee on Admissions and the D.C. Bail Agency.

He often was called on to address newly admitted members of the bar and participated in numerous seminars and panel discussions.

He was a member of the D.C., Washington, American and Federal Bar Associations, the American Judicature Society, Sigma Delta Tau legal fraternity and the National Lawyers Club, Inc.

Judge Fickling also was active in many community organizations, including the NAACP. He was a former officer of the Brookland Civic Association and former president and counsel of the Federation of Civic Associations.

He was an active member of the Washington Central Suffrage Conference in 1946, serving as a trustee. He also served as an alternate member of the former Special Police Trial Board and had been on the board of directors of the Columbia Hospital for Women for nine years.

He is survived by his wife, Dr. Doris Lee Dickens (Fickling), of the home; a son, retired Air Force Maj. Ralph L. Fickling, of Oxford, England; a daughter, Mrs. Criss Glaude, of Silver Spring; a sister, Carole M. Fickling, of Long Beach, Calif., and three grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the American Cancer Society.
