Devon Knitwear Co. v. Levinson
The plaintiffs filed a motion to strike an affirmative defense presented by the defendant labor union. The union argued that the plaintiffs came to court with 'unclean hands' due to their alleged refusal to bargain collectively, constituting an unfair labor practice under the National Labor Relations Act. Plaintiffs contended that the court lacked jurisdiction over unfair labor practices, as this power is exclusively vested in the National Labor Relations Board. The court clarified that while the NLRB has exclusive jurisdiction to *prevent* unfair labor practices, the court retains its inherent equitable power to deny relief to a party with 'unclean hands'. Therefore, the court found the union's defense legally sufficient and denied the plaintiffs' motion to strike.
