On the Hughes Court, Roberts was a swing vote positioned between the conservative Four Horsemen and the liberal Three Musketeers. Along with Chief Justice Charles Evans Hughes, Roberts's vote often decided whether President Franklin D. Roosevelt's New Deal legislation would be upheld. His decision to uphold the constitutionality of a state minimum wage law in "West Coast Hotel Co. v. Parrish" has been called "the switch in time that saved nine." That term references the decision's possible role in the defeat of the Judicial Procedures Reform Bill of 1937, which would have expanded the Supreme Court and thus allowed Roosevelt to appoint Justices more sympathetic to his policies. Roberts's motivation for upholding the constitutionality of the New Deal and his role in the defeat of the bill remains a matter of debate.
