render its decision to abandon the practices retroactive. It thus contends that its choice to reject the claims in order to avoid such effect was not based upon considerations of an arbitrary or unfair nature. Significantly, however, from 1943 to March 1962 the union consistently adhered to the practice of applying seniority on a racial basis, conduct which manifested a patent breach of its duty of fair representation. As the Supreme Court in Steele observed:
[T]he statutory power to represent a craft and to make contracts as to wages, hours, and working conditions does not include the authority to make among members of the craft discriminations not based on such relevant differences. * [Discriminations based on race alone are obviously irrelevant and invidious.
323 U.S. at 203, 65 S.Ct. at 232, 89 L.Ed. at 183; Conley v. Gibson, supra; see Brotherhood of Ry. Trainmen v. Howard, 1952, 343 U.S. 768, 72 S.Ct. 1022, 96 L.Ed. 1283; Tunstall v. Brotherhood of Locomotive Firemen, 1944, 323 U.S. 210, 65 S.Ct. 235, 89 L.Ed. 187; Syres v. Oil Workers Int’l. Union, 5th Cir. 1955, 223 F.2d 739, 745 (Rives, J., dissenting), rev’d per curiam, 1955, 350 U.S. 892, 76 S.Ct. 152, 100 L.Ed. 785. As the Board properly concluded, had the claims been allowed to proceed to arbitration, an arbitrator would not have been bound by the prior invalid interpretation of the contract and might well have awarded back wages. We thus conclude that where the record demonstrates that a grievance would have been processed to arbitration but for arbitrary and discriminatory reasons, the refusal to so process it constitutes a violation of the union’s duty to represent its members “without hostile discrimination, fairly, impartially, and in good faith.” Steele v. Louisville & N. R. R., supra, 323 U.S. at 204, 65 S.Ct. at 233, 89 L.Ed. at 184.
Similarly, with respect to the grievances concerning the segregated nature of plant facilities, the union not only refused to process such claims but actively opposed desegregation of shower and toilet facilities.9 It is impossible for us to look upon such conduct as anything other than an effort to discriminate against Negro employees with respect to conditions of employment. As exclusive representative of all employees in the bargaining unit, Local 12’s statutory obligation required it “to make an honest effort to serve the interests of all of those members, without hostility to any.” Ford Motor Co. v. Huffman, supra, 345 U.S. at 337, 73 S.Ct. at 686, 97 L.Ed. at 1057. In summarily refusing to consider in good faith the merits of these grievances, the union’s conduct inarguably failed to meet this standard. As the Board properly concluded, “whatever may be the bases on which a statutory representative may properly decline to process grievances, the bases must bear a reasonable relation to the Union’s role as bargaining representative or its functioning as a labor organization; manifestly racial discrimination bears no such relationship.” 150 N.L.R.B. at 312, 317.
We have been able to find but one appellate decision on the specific issue of whether a breach of the union’s duty of fair representation constitutes an unfair labor practice. NLRB v. Miranda Fuel Co., 2d Cir. 1963, 326 F.2d 172. That decision, moreover, was comprised of three separate opinions.10 Careful study of those opinions and the briefs in this case, in conjunction with the thorough and well-reasoned commentaries in this area,11 convinces us
