Dennis v. United States: Great Case Or Cold War Relic? Michal R. Belknap “Great cases like hard cases make bad law. For great cases are called great, not by reason oftheir real impor tance in shaping the law of the future, but because of some accident of im mediate overwhelming interest which appeals to the feelings and distorts the judgment.” Justice Holmes dissenting in Northern Securities Co. v. United States, 193 U.S. 197, 400 (1904). “[T]he most important reconciliation of lib erty and security in our time,” the Washington Post called the decision when the Supreme Court rendered it in 1951.1 Forty-two years laterDermis v. UnitedStates2 continues to occupy aprominent place in constitutional law casebooks.3 Butshould it? When the Courtdecided Dennis, the Cold War was at its most frigid, and the anticommunist hysteriaknownas McCarthyism grippedthe coun try. The decision reflected well the frenzied temper of those times, and it is certainly among the mostprominentlegalproductsofthe McCarthy era. The Cold Warhas ended, however, and today the doctrinal significance of Dennis v. United States is minimal. Far from the “big case” it once seemed to be, Dennis now looks like little more than a legal relic of a bygone era. The time has come to ask whether it is just a twentieth century Dred Scott decision,4 truly important only to historians and those fascinated by the Supreme Court. Whatever its current significance, the Dennis decision clearlywas, as Thomas I. Emerson noted in 1970, “one ofthe most influential in the post warperiod.”5 “Everything,” as Harry Kalven, Jr., has observed, “conspired to make Dennis a great moment.”6 Reaching the Supreme Court at the height of the country’s preoccupation with do mestic communism, the case “involved the crimi nal prosecution ofeleven leaders ofthe Commu nist Party,” and was an outgrowth ofwhat Kalven called, withouttoo much exaggeration, “the great American political trial.”7 Thattrialwas in turn, as PeterL. Steinbergand I have demonstrated, the product of a blatantly political prosecution.8 When the World War II alliance between the United States and the Soviet Union deteriorated into a postwar confrontation over the future of Central and Eastern Europe, President Harry S. Truman sought to rally the on the campaign trail in Fargo, North Dakota in 1948. 42 JOURNAL 1993 American people behind costly international ini tiatives designed to check Soviet expansionism by characterizing what was essentially a conflict of interest between two powerful nation states as a struggle between communism and democracy. Capitalizing on the traditional American ten dency to define international issues in moral terms and playing on traditional American fears ofradicalism, Truman managed to enlist biparti san support for his anti-Soviet foreign policy, but at ahigh politicalprice. In 1944 some Republican conservativeshadattemptedto discreditTruman’s Democratic party by linking it to communism. Votershad displayed little interest in such charges then, but by 1948, with the aid ofsome spectacu lar revelations of Communist espionage during the 1930s and early 1940s, a threatening interna tional situation and the president’s inflated rheto ric had made what was once a non-issue into a compelling concern. Itwas not a worry ofTruman and his advisers, who considered communism an international problem, not a domestic one. The president dismissed the Communist Party of the United J. Edgar Hoover (left) with Justice Hugo Black in 1965. As Director of the FBI, Hoover suggested that the Justice Department use the Smith Act against the CPUSA. States of America (CPUSA), which had only 60,000 members in 1948, as a “contemptible minority in a land offreedom.” Many Americans did not find his position persuasive, for if what menaced America was communism, then surely Republicans were right in claiming that Reds in New York City, and especially in the federal government in Washington, were a threat to national security. By April 1947, sixty-one per centofAmericansfavoredoutlawingthe CPUSA, a percentage thatrose in succeeding months. Led by the House Committee on Un-American Ac tivities (HUAC), Republicans hammered away at the Truman administration for not doing more to combatthis Red menace. Endeavoring to protect itself against GOP charges that it was soft on subversion, the administration initiated a loyaltysecurity program for federal employees. But Republicans and conservative Democrats...
