In Allegheny Ludlum Steel Corp. v. Kelley, 330 U.S. 767 (1947), suit had been brought in the state court for a declaratory judgment to restrain the state labor board from determining a representative of plaintiff's supervisory employees to bargain collectively with the plaintiff. Under New York law the labor board had authority to hold elections to determine employee representation and to certify the results. 30 McKinney's Cons. Laws 705. Certification in itself, as in the instant case, did not impose a legal penalty. Suit had to be brought in an unfair labor practice proceeding to accomplish such result. 30 Ibid. 706. Refusal to bargain with the representative of the employees was an unfair labor practice. 30 Ibid. 704 (6). Even though the New York law did not state, as does the Wisconsin law, that certification by the board was conclusive, we considered a decision of the New York court approving the jurisdiction of the state board to conduct a representative proceeding a final judgment ripe for our consideration.
