 Along with "NLRB v. Fansteel Metallurgical Corp.", 306 U.S. 240 (1939) and "NLRB v. Columbian Enameling & Stamping Co.", 306 U.S. 292 (1939), the decision has been called one of the three most significant NLRB cases since "NLRB v. Jones & Laughlin Steel Corp.", 301 U.S. 1 (1938) upheld the NLRA's constitutionality.The three cases also expanded the way the Court interpreted the NLRA.Although the justices had previously interpreted the Act solely through the lens of the Commerce Clause (showing strong deference to the Board), now the Court evinced a willingness to apply evidentiary standards to the Board's actions and to impose a less radical interpretation on the law.
