In the case of Virginian Railway Co. v. System Federation No. 40, Railway Employees Department of the American Federation of Labor et al., the Supreme Court ruled in favor of labor unions' right to organize and bargain collectively under Section 2, Ninth of the Railway Labor Act (RLA). The Virginian Railway Company had refused to recognize or negotiate with a union representing its employees, arguing that it was not obligated to do so because some members were not actual employees but rather paid organizers from outside organizations like AFL-CIO. However, the court held that these external affiliations did not disqualify them as representatives for collective bargaining purposes under RLA provisions. Furthermore, it found that federal courts could issue injunctions against employers who refuse to comply with their statutory obligations towards employee representation and negotiation processes mandated by RLA.

In the dissenting opinion for Virginian Railway Co. v. System Federation No. 40, it was argued that the majority had overstepped its bounds by interpreting the Railway Labor Act in a way that went beyond what Congress intended when they passed it. The dissenters believed that while Congress did intend to promote collective bargaining and peaceful labor relations, they did not mean to force employers into recognizing unions against their will or without a clear indication of employee support for unionization. They also took issue with how broadly the majority interpreted "interference" and "influence," arguing this could potentially criminalize any employer action disfavoring unions even if such actions were part of normal business operations or decisions made in good faith based on legitimate business concerns rather than anti-union animus.
