Recent decisions of the United States Supreme Court and of this court are controlling authority that appellants’ action under section 301 of the Labor Management Relations Act, 29 U.S.C. § 185(a) (Supp. Ill 1976), seeking to enforce the terms of a § 8(f) prehire agreement, 29 U.S.C. § 158(f) (Supp. Ill 1976), may not be dismissed for lack of subject matter jurisdiction on either of the two grounds asserted by appellees in their motion to dismiss.

In Jim McNeff, Inc. v. Todd, - U.S. -, 103 S.Ct. 1753, 75 L.Ed.2d 830 (1983), the Supreme Court held that a § 8(f) agreement is judicially enforceable under § 301 prior to repudiation even absent proof that the union represented a majority of the *521employees. In Brotherhood of Teamsters, Local No. 70, v. California Consolidators, Inc., 693 F.2d 81 (9th Cir. 1982), our court held that § 301 grants the district court jurisdiction to decide whether employers constitute a single employer, although not to determine the appropriateness of the bargaining unit. California Consolidators is therefore controlling authority that the district court has jurisdiction to decide whether Low Hydro is bound to the prehire agreement signed by A-l Boring. This issue is primarily contractual, not representational. Id. at 83, n. 4.

In remanding the case to the district court, we express no view on the question whether appellees effectively repudiated the prehire agreement. The record before us does not indicate whether appellees took any appropriate action to repudiate the agreement. Accordingly, it is unnecessary to decide at this time “what specific acts would effect the repudiation of a prehire agreement ...” Jim McNeff, Inc. v. Todd, -U.S. at -, n. 11, 103 S.Ct. at 1759, n. II.1
