In light of the at least partial overlapping of functions and duties imposed upon the Attorney General by Executive Order 10450 and the Subversive Activities Control Act. it is evident that these relationships must be clarified. Moreover. the ultimate failures of the Attorney General under both procedures undoubtedly rest on similar causes. The program under Executive Order 9835. after an apparently successful beginning. subsequently deteriorated following a decision of the Supreme Court in Joint AntiFascist Refugee Committee v. McGrath. 341 U.S. 123 (1951). which enjoined the Attorney General from designating relevant organizations without hearings. On the other hand. at its inception. the program under the Subversive Activities Control Act of 1950 required full trialtype proceedings in the determination of Communist organizations. and little progress was made in its execution.
