“ Despite the completion of construction, our superintendence of a state court injunction against conduct alleged to be cognizable exclusively by the National Labor Relations Board is desirable 'if the danger of state interference with national policy is to be averted,' San Diego Building Trades Council, Millmen's Union, Local 2020 v. Garmon, 359 U.S. 236, 245, 79 S.Ct. 773, 780, 3 L.Ed.2d 775. This controversy involves the fundamental question of whether the Tennessee courts had any power whatever to adjudicate the dispute between the parties. ”

“ The petitioners moved promptly in the Chancery Court to dissolve the injunction on the ground that the state court was without jurisdiction to adjudicate the controversy because the subject matter of the picketing was exclusively within the cognizance of the National Labor Relations Board. ”

“ The Chattanooga Building Trades Council, AFL, is composed of 17 building trades unions, including Hod-Carriers Building and Common Laborers' Union of America and its Local 846, two of the petitioners. Respondent Rea Construction Company, a large North Carolina building contractor, was engaged by respondent Jafco, Inc., as general contractor to erect a shopping center on a site in Cleveland, Tennessee. Rea operated an open shop, and workers on the project were paid lower wages than the union scale. ”
