The U.S. Supreme Court case National Labor Relations Board v. Columbian Enameling & Stamping Co., 1938, centered around the issue of unfair labor practices and the power of the National Labor Relations Board (NLRB). The NLRB had found that Columbian Enameling & Stamping Co. was guilty of unfair labor practices by interfering with, restraining, and coercing its employees in their rights to self-organization for collective bargaining as guaranteed under Section 7 of the Wagner Act (National Labor Relations Act). The company contested this decision arguing that it did not engage in any such activities and also challenged the constitutionality of certain provisions within the act itself. However, upon reaching Supreme Court level review, it was held that there was enough evidence supporting NLRB's findings against Columbian Enameling & Stamping Co., thereby affirming its authority to prevent and remedy unfair labor practices. Additionally, all constitutional challenges raised against sections 10(c) and 10(f) were dismissed on grounds they do not violate due process or impede judicial review.

The dissenting opinion in the case of National Labor Relations Board v. Columbian Enameling & Stamping Co., 1938, argued that the majority's decision to uphold a cease and desist order against the company for unfair labor practices was an overreach of power by the National Labor Relations Board (NLRB). The dissent contended that while there were instances where employees had been unjustly dismissed, it did not constitute a general practice of discouraging union membership as alleged by NLRB. It also criticized NLRB’s broad interpretation of “unfair labor practices” which could potentially include any act employers might take in relation to their employees. Furthermore, they disagreed with ordering reinstatement and back pay for all discharged workers without individual examination or proof that each discharge was related to union activity or collective bargaining efforts. They believed this blanket approach violated due process rights under Fifth Amendment.
