as "The Four Horsemen". Opposed to them were the liberal Justices Louis Brandeis, Benjamin Cardozo and Harlan Fiske Stone, dubbed "The Three Musketeers". Chief Justice Charles Evans Hughes and Justice Owen Roberts were regarded as the swing votes on the court. Recent scholarship has eschewed these labels since they suggest more legislative, as opposed to judicial, differences. While it is true that many rulings of the 1930s Supreme Court were deeply divided, with four justices on each side and Justice Roberts as the typical swing vote, the ideological divide this represented was linked to a larger debate in U.S. jurisprudence regarding the role of the judiciary, the meaning of the Constitution, and the respective rights and prerogatives of the different branches of government in shaping the judicial outlook of the Court. Roberts had voted to grant certiorari to hear the Parrish case before the election of 1936. Oral arguments occurred on December 16 and 17, 1936, with counsel for Parrish specifically asking the court to reconsider its decision in Adkins v. Children's Hospital, which had been the basis for striking down a New York minimum wage law in Morehead v. New York ex rel. Tipaldo in the late spring of 1936. In Tipaldo, the appellant had not challenged the Adkins precedent. Having no "case or controversy" legs upon which to stand, Roberts and the rest of the majority deferred to the Adkins precedent, voting to strike the New York statute. Justice Butler authored the opinion of the Court in the Tipaldo case. He and the rest of the majority, excluding Roberts, shortly thereafter found themselves in the minority on the Parrish case. In the Parrish case, Roberts indicated his desire to overturn Adkins immediately after oral arguments on December 17, 1936. The initial conference vote on December 19, 1936, was split 4–4; with this even division on the Court, the holding of the Washington Supreme Court, finding the minimum wage statute constitutional, would stand. The eight voting justices anticipated Justice Stone—absent due to illness—would be the fifth vote necessary for a majority opinion affirming the constitutionality of the minimum wage law. As Chief Justice Hughes desired a clear 5–4 affirmation of the Washington Supreme Court's judgment, rather than a 4–4 default affirmation, he convinced the other justices to wait until Stone's return before both deciding and announcing the case.
