E. GRADY JOLLY, Circuit Judge:

In this section 301 action ( 29 U.S.C. § 185(a)), which arises out of Mar-Len's repudiation of its pre-hire agreements with the unions, the question presented is whether the NLRB's interpretation of § 8(f) of the National Labor Relations Act, 29 U.S.C. § 158(f), announced in Deklewa v. International Association of Bridge Workers, Local No. 3, 282 N.L.R.B. 184 (1987), is the controlling law in this circuit and is to be applied retroactively in this case. Mar-Len and the unions appeal the district court's decision, which refused to apply Deklewa retroactively and held that, although, under the pre- Deklewa law, Mar-Len was precluded from unilaterally repudiating its pre-hire agreements because the unions had achieved majority status, the agreements nevertheless expired by their own terms. We conclude that Deklewa cannot be applied retroactively in this case and, because the district court erred in finding that the unions had achieved majority status at the time of Mar-Len's repudiation, we reverse.

The parties stipulated to the following facts. Mar-Len of Louisiana, Inc. ("Mar-Len") is a construction contractor. The International Association of Bridge, Structural, and Ornamental Iron Workers, Local Union No. 678 ("Iron Workers"), United Brotherhood of Carpenters and Joiners of America, Local Union 953 ("Carpenters"), and Construction and General Laborers, Local Union 207 ("Laborers") are labor unions. Mar-Len entered into pre-hire agreements with the Carpenters, on January 27, 1981; the Iron Workers on February 29, 1981; and the Laborers, on January 27, 1981, and August 5, 1981. These pre-hire agreements, styled "Assent Agreements," bound the parties to the terms of master collective bargaining agreements entered into between the unions and the Associated General Contractors, Inc.

Pursuant to a contract with the City of DeRidder, Louisiana, ("DeRidder"), Mar-Len commenced work on the DeRidder Phase Two Wastewater Improvements-Transfer Stations on April 15, 1983. On January 19, 1984, after a contract dispute with DeRidder, Mar-Len ceased work on the project as a result of the city's failure to pay.

On June 5, 1984, Mar-Len notified the unions that it repudiated any collective bargaining agreements that were in effect, asserting its right to do so pursuant to this court's holdings in Baton Rouge Building and Construction Trades Council, AFL-CIO v. E.C. Schafer Construction Co., Inc., 657 F.2d 806 (5th Cir. 1981) and NLRB v. Haberman Construction Co., 641 F.2d 351 (5th Cir. 1981). On July 12, 1984, Mar-Len similarly advised each of the union's fringe benefit funds that it had repudiated any agreements and refused to make any further contributions.

After Mar-Len resumed work on the project following a settlement with DeRidder on October 9, 1985, the unions formally grieved the company's failure to rehire the workers laid off in January 1984 and its failure to use the unions' hiring hall for rehire purposes. Mar-Len responded by denying the existence and/or validity of any collective bargaining agreement between the company and the unions. The Carpenters worked on the wastewater project through the week ending November 11, 1986; the Iron Workers, the week ending March 18, 1986; and the Laborers, the week ending November 25, 1986.

On March 10, 1986, the Carpenters and the Laborers instituted this action against Mar-Len, alleging that the company had unlawfully repudiated the collective bargaining agreements that covered work performed at the DeRidder wastewater facility. On April 28, 1986, the Iron Workers also filed suit against Mar-Len, asserting substantially the same allegations. Both actions, which were consolidated, were brought under section 301 of the Labor Management Relations Act and sought declaratory and monetary relief, including lost wages, benefits, and attorney's fees.

On November 17, 1988, the district court issued its opinion. After first determining that it had jurisdiction of the case under section 301, the court noted that the issue was whether, in repudiating the collective bargaining agreements with the unions, Mar-Len violated section 8(f), 29 U.S.C. § 158(f). The court then noted that at the time Mar-Len and the unions entered into their pre-hire agreements, the NLRB's interpretation of § 8(f), which had been affirmed by the Supreme Court in NLRB v. Local Union No. 103, International Association of Bridge, Structural and Ornamental Iron Workers, AFL-CIO, 434 U.S. 335, 98 S.Ct. 651, 54 L.Ed.2d 586 (1978) ( Higdon), and followed by this court, see NLRB v. Haberman Construction Co., 641 F.2d 351 (5th Cir. 1981); Baton Rouge Building and Construction Trades Council v. E.C. Schafer Construction Co., Inc., 657 F.2d 806 (5th Cir. 1981); Carpenters Local Union No. 1846 v. Pratt-Farnsworth, 690 F.2d 489 (5th Cir. 1982) was that pre-hire agreements are unilaterally voidable unless and until the relevant union achieves majority status. The district court further noted, however, that the NLRB had later reversed itself in Deklewa v. International Association of Bridge Workers, Local No. 3, 282 NLRB 184 (1987), enforced 843 F.2d 770 (3rd Cir. 1988), holding that pre-hire agreements may not be repudiated prior to expiration, except pursuant to a vote to decertify the union under § 9(c) or 9(e). The district court concluded that Deklewa should be followed in this circuit but declined to apply it retroactively in the instant case. In support of this determination, the district court, citing Construction Industry Welfare Fund of Rockford, Illinois v. George M. Jones, 672 F. Supp. 291 (N.D.Ill. 1987), noted that the policies Deklewa identified as underlying § 8(f) — freedom of contract and promoting employee free choice and labor relations stability — would not be furthered by retroactive application under the circumstances of this case: that is, prohibiting Mar-Len from voiding its pre-hire agreements with the unions would serve to penalize the company for undertaking an act that, at the time it did so, it was legally permitted to do.

The district court next found, however, that when Mar-Len repudiated the pre-hire agreements on June 5, 1984, the unions had achieved majority status; therefore, it held that, under the pre- Deklewa rule, Mar-Len was precluded from unilaterally repudiating the pre-hire agreements. The court further held, however, that Mar-Len's letter to the unions on June 5, 1984, in which it denied the existence of a valid collective bargaining agreement and repudiated any agreement alleged to exist, caused the pre-hire agreements to expire by their own terms on the following dates: the Laborers, on April 30, 1985; the Carpenters, on May 1, 1985; and the Iron Workers, on April 30, 1986.

Finally, the district court declined to award the unions attorney's fees to the unions. It concluded that Mar-Len's repudiation of the pre-hire agreements was founded upon its reasonable belief that it had a right to do so.

The district court entered judgment for the unions on June 1, 1989. It awarded back pay and fringe benefits to two members of the Iron Workers. Yet, because the district court held that their pre-hire agreements terminated before Mar-Len resumed work on the DeRidder project, the Carpenters and the Laborers received no compensation. Mar-Len and the unions timely appealed.

The primary question before us is whether the NLRB's present interpretation of § 8(f), announced in Deklewa, is the controlling law in this circuit and is to be applied retroactively in this case. We will assume for the purpose of this opinion that Deklewa is the controlling law in this circuit, see Deklewa, 843 F.2d 770 (3rd Cir. 1988); NLRB v. W.L. Miller Co., 871 F.2d 745 (8th Cir. 1989); Mesa Verde Construction Co. v. Northern California District Council of Laborers, 885 F.2d 594 (9th Cir. 1989), on remand after 861 F.2d 1124 (9th Cir. 1988) (en banc); NLRB v. Bufco Corp., 899 F.2d 608 (7th Cir. 1990), but we need not decide the actual question because we hold that, in any event, Deklewa cannot be applied retroactively in this case.

In deciding whether Deklewa is to be applied to this case, we look to the factors set out in Chevron v. Huson, 404 U.S. 97, 92 S.Ct. 349, 355, 30 L.Ed.2d 296 (1971) as relevant to the question of nonretroactivity: first, whether Deklewa establishes a new principle of law, either by overruling clear past precedent on which the parties may have relied or by deciding an issue of first impression whose resolution was not clearly foreshadowed; second, whether in the light of the prior history of § 8(f), its purpose and effect, retroactive application of Deklewa furthers or retards its operation; and third, whether retrospective application would produce substantial inequitable results. See Phillips v. Marine Concrete Structures, Inc., 895 F.2d 1033, 1036 (5th Cir. 1990). First, the nonvoidability of pre-hire agreements is a new rule insofar as it overrules past precedent on which Mar-Len clearly relied, as evidenced by its June 5, 1984 letters to the unions in which it specifically cited Baton Rouge Building and Construction Trades Council, AFL-CIO v. E.C. Schafer Construction Co., Inc., 657 F.2d 806 (5th Cir. 1981) and NLRB v. Haberman Construction Co., 641 F.2d 351 (5th Cir. 1981), in repudiating the pre-hire agreements. The turnabout on the part of the NLRB was not clearly foreshadowed by the Board's prior cases. Second, we are unable to conclude that retrospective application of Deklewa would further the operation of the Board's new interpretation of § 8(f) because work on the job at issue is complete. Finally, with respect to the third Chevron factor, we conclude that retroactive application of Deklewa would produce "substantial inequitable results." This is true because, as we noted earlier, Mar-Len entered into its pre-hire agreements with the unions relying on its then-existing right to repudiate unilaterally the agreements so long as the unions had not achieved majority status. Furthermore, Mar-Len expressly relied on this established right when it unilaterally repudiated the agreements on June 5, 1984, prior to the Board's decision in Deklewa. Finally, because, as the unions conceded at oral argument, there is no evidence in the record that they had achieved majority status prior to repudiation, we conclude that it would work inequitable and unjust results to apply Deklewa retroactively. We, therefore, hold that, even if we adopted Deklewa, we would not apply it retroactively so as to hold Mar-Len liable. Therefore, although we agree with the district court that Deklewa should not be applied retroactively, there is no evidence to support the district court's holding that the unions ever achieved majority status. Thus, the district court's holding that Mar-Len was precluded from unilaterally repudiating the pre-hire agreements, and its judgment in favor of the unions must be reversed. We, therefore, reverse and remand for entry of a judgment of dismissal.

REVERSED and REMANDED for entry of judgment.
