Roberts was
nominated by President
Herbert Hoover on May 9, 1930, as an
associate justice of the Supreme Court of the United States of the Supreme Court, to succeed
Edward Terry Sanford. Hoover selected Roberts after his previous nominee,
John J. Parker, had been rejected by the Senate. In contrast to Parker, Roberts was confirmed by voice vote on May 20, 1930. He took the judicial oath of office on June 2, 1930.
"Switch in Time that Saved Nine" Roberts switched his position on the constitutionality of the New Deal in late 1936, and the Supreme Court handed down
West Coast Hotel v. Parrish in 1937, upholding the constitutionality of minimum wage laws. Subsequently, the Court would vote to uphold all New Deal programs. Since President Roosevelt's plan to appoint several new justices as part of his "
Court-packing" plan of 1937 coincided with the Court's favorable decision in Parrish, many people called Roberts's vote in that case "
The switch in time that saved nine," although Roberts's vote in
Parrish occurred several months before announcement of the Court-packing plan. While Roberts is often accused of inconsistency in his jurisprudential stance towards the New Deal, legal scholars note that he had previously argued for a broad interpretation of government power in the 1934 case of
Nebbia v. New York, and so his later vote in
Parrish was not a complete reversal. Roberts, however, had sided with the
four conservative justices in finding a similar state minimum wage in New York unconstitutional in June 1936. Because the announcement of the Parrish decision took place in March 1937, one month after Roosevelt announced his plan to pack the court, it created speculation that Roberts had voted in favor of Washington's state minimum wage law because he had succumbed to political pressure. However, Chief Justice
Charles Evans Hughes contended in his autobiographical notes that Roosevelt's attempt to pack the court "had not the slightest effect" on the Court's ruling in the Parrish case and records showed that Roberts indicated his desire to uphold Washington state's minimum wage law two months prior to Roosevelt's court-packing announcement in December 1936. On December 19, 1936, two days after oral arguments ended for the Parrish case, Roberts voted in favor of Washington's state minimum wage law, but the Supreme Court was divided 4–4 because pro-New Deal Associate Justice
Harlan Fiske Stone was absent due to an illness; Hughes was able to persuade Roberts to no longer base his votes on his own political beliefs and side with him during future votes on New Deal related policies. In one of his notes from 1936, Hughes wrote that Roosevelt's re-election forced the court to depart from "its fortress in public opinion" and severely weakened its capability to base its rulings on personal or political beliefs. was a master stroke. What the public overlooked was that Roberts had been one of the most clamorous among those screaming for an open declaration of war. He had doffed his robes, taken to the platform in his frantic apprehensions and demanded that we immediately unite with Great Britain in a single nation. The Pearl Harbor incident had given him what he had been yelling for – America's entrance into the war. On the war issue he was one of the President's most impressive allies. Now he had his wish. He could be depended on not to cast any stain upon it in its infancy. Perhaps influenced by his work on the Pearl Harbor commission, Roberts dissented from the Court's decision upholding internment of Japanese-Americans along the
West Coast in 1944's
Korematsu v. United States. The second
Roberts Commission was established in 1943 to consolidate earlier efforts on a national basis with the US Army to help protect monuments, fine arts, and archives in war zones. The commission ran until 1946, when its activities were consolidated into the
State Department. Roberts also played a key role in the creation of the OSS
Art Looting Investigation Unit (ALIU) which investigated and documented Nazi plunder networks in Europe. In his later years on the bench, Roberts was the only Justice on the Supreme Court who was not appointed (or, in the case of Stone, who had become Chief Justice, promoted) by President
Franklin D. Roosevelt. Roberts became frustrated with the willingness of the new justices to overturn precedent and with what he saw as their result-oriented liberalism as judges. Roberts dissented bitterly in the 1944 case of
Smith v. Allwright, which found the white primary unconstitutional and overruled
an opinion that had been written by Roberts himself a mere nine years earlier. He coined in that dissent the oft-quoted phrase that the frequent overruling of decisions "tends to bring adjudications of this tribunal into the same class as a restricted railroad ticket, good for this day and train only".
Retirement Roberts retired from the Court the following year, in 1945; Roberts's relations with his colleagues had become so strained that fellow Justice
Hugo Black refused to sign the customary letter acknowledging Roberts's service on his retirement. Other justices refused to sign a modified letter that would have been acceptable to Black, and in the end, no letter was ever sent. Shortly after leaving the Court, Roberts reportedly burned all of his legal and judicial papers. As a result, there is no significant collection of Roberts's manuscript papers, as there is for most other modern Justices. Roberts did prepare a short memorandum discussing his alleged change of stance around the time of the court-packing effort, which he left in the hands of Justice
Felix Frankfurter. ==Later life==
