At the conclusion of the hearings, the board revoked Oppenheimer's clearance by a 2–1 vote. It unanimously cleared him of disloyalty, but a majority found that 20 of the 24 charges were either true or substantially true and that Oppenheimer would represent a security risk. Then on June 29, 1954, the AEC upheld the findings of the Personnel Security Board, by a 4–1 decision, with Strauss writing the majority opinion. In that opinion, he stressed Oppenheimer's "defects of character", "falsehoods, evasions and misrepresentations", and past associations with Communists and people close to Communists as the primary reasons for his determination. He did not comment on Oppenheimer's loyalty.
