John Eugene Cleary, 60, an associate counsel for the Washington Suburban Sanitary Commission, died Saturday after being run over accidentally by a tractor from which he fell at his farm in Sperryville, Va.

Mr. Cleary was taken to Culpeper Memorial Hospital, where he was pronounced dead. He was a resident of Camp Springs, Md., but often spent weekends at his Virginia farm.

A native of Washington, Mr. Cleary completed a 27-year Air Force career before joining the legal staff of the WSSC in 1968.

At the WSSC, he headed the environmental law section of the general counsel's office and was responsible for litigation arising from environmental law at state and local levels.

Mr. Cleary graduated from Western High School in 1937 and four years later from Catholic University's law school. He served as an enlisted man during World War II, then received a commission in the Air Force judge advocate general's office in the mid-1940s. He served at bases both here and abroad before retiring as a lieutenant colonel in 1968.

An outdoorsman and canoeist, Mr. Cleary was a former Boy Scout leader in Prince George's County. He also was a member of the American, Maryland, Prince George's and District of Columbia bar associations.

Survivors include his wife, Dorothy Ann, two daughters, Brigid Louise and Deirdre Marie, and a son, Sean Eugene, all of the home; another daughter, Alice C. Galligan of Largo; two brothers, Daniel J., of Richmond and James L., of Washington, and three sisters, Mary Elizabeth Ritzert of Fairfax, Margaret Louise Gray of Gettysburg, Pa., and Alice C. Vermillion of Miami.
