Court of Appeals for the D.C. Circuit June 12, 1990, No. 89-1458 (Sheet Metal Workers, Local Union No. 91 v. National Labor Relations Board)

HARRY T. EDWARDS, Circuit Judge:

The issue in this case is whether respondent, National Labor Relations Board (“NLRB” or “Board”), properly determined that contractual language drafted by petitioners Sheet Metal Workers International Association (“International”) and Sheet Metal Workers Local Union No. 91 (“Local No. 91”) (collectively “Union”) amounts to an unlawful “hot cargo” clause.
