National L. Rel. Board v. Appalachian E. Power

In National Labor Relations Board v. Appalachian Electric Power Co., 4 Cir., 140 F.2d 217, 224, the court, following the rule announced in the Third Circuit in National Labor Relations Board v. Botany Worsted Mills Co., supra, held that where a bargaining agent was selected by employees in an election supervised by the Board, they could not repudiate it within ten weeks thereafter, as such conduct would preclude the adequate protection of the very rights which the Act was designed to secure.
