James V. Constantine, 74, who retired in 1976 as an administrative law judge with the National Labor Relations Board, died Wednesday at Suburban Hospital. He had undergone surgery for a brain turmor.

Mr. Constantine, who lived in Bethesda, joined the NLRB as a lawyer in 1948. He became special assistant to the general counsel in 1955 and later that year was named solicitor. He was appointed an administrative law judge in 1961.

He served on a committee that drafted the procedures followed by the NLRB after passage of the Taft-Hartley Act. The Supreme Court twice sustained his decisions, one involving the right to bargain on retirement income and the other the right of employes to union representation in cases that might lead to disciplinary procedures.

Mr. Constantine was born in Smyrna, yasia Minor. He came to this country as a child with his family. He attended the University of Pennsylvania and graduated from Harvard University, where he was elected to Phi Beta Kappa. He graduated from Harvard Law School in 1931 and entered private practice in Springfield, Mass. He moved to the Washington area in 1944 and was a lawyer with the Civil Aeronautics Administration before joining the NLRB.

Survivors include his wife, the former Antoinette Kouioyen, of Bethesda; four children, James V. Jr., of Bricktown, N.J., Paulina I. Masick of Damascus, Md., Philip S., of Bethesda, and George Theodore, of Gaithersburg, and a brother, George, of Wilbraham, Mass.
