Upon the certification of the results of such ballot or upon a settlement being reached, whichever happens sooner, the Attorney General shall move the court to discharge the injunction, which motion shall then be granted and the injunction discharged. When such motion is granted, the President shall submit to the Congress a full and comprehensive report of the proceedings, including the findings of the board of inquiry and the ballot taken by the National Labor Relations Board, together with such recommendations as he may see fit to make for consideration and appropriate action.
