“ We think that the provision of the National Labor Relations Act conferring exclusive power upon the Board to prevent any unfair labor practice, as defined,-a power not affected by any other means of 'prevention that has been or may be established by agreement, code, law, or otherwise', necessarily embraces exclusive authority to institute proceedings for the violation of the court's decree directing enforcement. ”

“ If the decree of enforcement is disobeyed, the unfair labor practice is still not prevented. The Board still remains as the sole authority to secure that prevention. The appropriate procedure to that end is to ask the court to punish the violation of its decree as a contempt. As the court has no jurisdiction to enforce the order at the suit of any private person or group of persons, we think it is clear that the court cannot entertain a petition for violation of its decree of enforcement save as the Board presents it. ”

“ To attain its object Congress created a particular agency, the National Labor Relations Board, and established a special procedure. The aim, character and scope of that special procedure are determinative of the question now before us. Within the range of its constitutional power, Congress was entitled to determine what remedy it would provide, the way that remedy should be sought, the extent to which it should be afforded, and the means by which it should be made effective. ”
