In the case of Drake Bakeries Inc. v. Local 50, American Bakery & Confectionery Workers International, AFL-CIO et al., 1961, the U.S Supreme Court ruled in favor of Drake Bakeries Incorporated. The dispute arose when a union picketed at one of Drake's customers to compel them to stop doing business with the bakery due to an ongoing labor dispute between Drake and its employees who were members of that union. The court held that such secondary boycotts were prohibited under Section 8(b)(4)(A) of the National Labor Relations Act (NLRA). This section prohibits unions from pressuring neutral third parties - like customers or suppliers - into supporting their cause during a labor dispute with an employer. Therefore, it was illegal for the union to attempt to involve a customer in its conflict with Drake by trying to force them not only into taking sides but also damaging their own commercial interests as well.

In the dissenting opinion for Drake Bakeries Incorporated v. Local 50, American Bakery & Confectionery Workers International, AFL-CIO et al., Justice Frankfurter argued that the majority's decision was a departure from established principles of labor law and policy. He contended that the National Labor Relations Act (NLRA) did not intend to give courts such broad authority to interfere in labor disputes or impose their own views on what constitutes fair bargaining practices. Instead, he believed it should be left up to the National Labor Relations Board (NLRB), which has specialized knowledge and experience in these matters. Furthermore, he disagreed with the majority's interpretation of "good faith" negotiations under NLRA - arguing that an employer is not required by law to agree with union demands or make counteroffers they deem unreasonable. In his view, this case represented an unwarranted judicial intrusion into collective bargaining process.
