In the case of National Labor Relations Board v. Deena Artware, Inc., et al., 1959, the U.S Supreme Court ruled in favor of the National Labor Relations Board (NLRB). The NLRB had found that Deena Artware and other companies involved were guilty of unfair labor practices by refusing to bargain with a union representing their employees. However, these findings were initially set aside by an appellate court on grounds that there was insufficient evidence to support them. Upon review, the Supreme Court held that substantial evidence did indeed exist supporting the NLRB's determination and thus reinstated its original order for remedial action against Deena Artware and others implicated in violating employee rights under Section 8(a)(5) of the National Labor Relations Act - which requires employers to negotiate with duly elected representatives regarding wages, hours or working conditions.

The dissenting opinion in the case of NATIONAL LABOR RELATIONS BOARD v. DEENA ARTWARE, INC., et al., argued that the majority's decision to uphold a cease and desist order issued by the National Labor Relations Board (NLRB) against Deena Artware was incorrect. The dissenters believed that there was insufficient evidence to support NLRB's claim that Deena Artware had interfered with its employees' rights under Section 7 of the National Labor Relations Act. They also disagreed with NLRB’s interpretation of what constitutes an unfair labor practice, arguing it overstepped its authority by attempting to regulate employer-employee relations beyond what is specified in law. Furthermore, they contended that even if such interference did occur, it would not necessarily constitute an unfair labor practice unless it resulted in prejudice or harm towards employee rights - something which they felt had not been adequately demonstrated in this case.
