OPINION OF THE COURT
Under section 301 of the National Labor-Management Relations Act of 1947 (“the NLMRA”),
1
an individual employee may bring an action charging his employer with breach of the collective bargaining agreement, and his union with violating its duty of . fair representation in mishandling the ensuing grievance. Vaca
v. Sipes,
Appellant John T. Perez brought this
Vaca-Hines
suit against appellees Dana Corporation, Parish Frame Division (“the Company”) and United Steelworkers of America, Local Union No. 3733 (“the Union”). Perez alleged that the Company breached the collective bargaining agreement by discharging him, and that the Union violated its duty of fair representation by failing to pursue his grievance. The district court held that

Teamsters,-U.S.-,
I
On September 12, 1979, Perez got into a brawl with a co-worker at the Company’s Reading, Pennsylvania facility. The Company suspended Perez pending determination of the appropriate penalty. Seeking to reverse the suspension, Perez filed a grievance pursuant to the applicable provisions of the collective bargaining agreement. A hearing on the grievance was held on September 27, 1979. On October 2, 1979, the Company converted the suspension into a discharge. On October 5, 1979, the Union informed Perez that it would not take his grievance to arbitration. Perez states that his cause of action against the Company and the Union arose “on or about October 5, 1979.” Amended Brief of Appellant at xiii.
On September 10,1980, this court decided
Liotta v. National Forge Co.,
Responding to the conflict in the circuits created by
Liotta,
the Supreme Court on April 20, 1981, decided
United Parcel Service v. Mitchell,
*584 On September 18, 1981, twenty-three months after his cause of action arose, Perez filed suit against the Company and the Union in the United States District Court for the Eastern District of Pennsylvania. In his complaint Perez alleged that his discharge violated the penalty provisions of the collective bargaining agreement. Perez also alleged that the Union violated its duty of fair representation by refusing to represent him in the initial grievance hearings or carry his grievance to the arbitration stage. 3 In its answer the Union asserted that Perez’s claims were barred because his suit was brought outside the limitations period established by section 10(b) of the NLRA. The Company filed a motion to dismiss on the grounds that Perez had failed to file his suit either within the limitations period of section 10(b) or of the Pennsylvania statute of limitations for actions to vacate arbitrator’s awards. The Union then moved for summary judgment based on Perez’s failure to bring suit within either limitations period.
On August 13, 1982, the district court granted the Company’s motion to dismiss and the Union’s motion for summary judgment.
Perez filed a notice of appeal to this court on September 13, 1982. While that appeal was pending the Supreme Court decided

As a general rule an appellate court must apply the law in effect at the time it renders its decision.

Chevron Oil Co. v. Huson,
A. The Change from Prior Law
To determine whether
DelCostello
established a new principle of law by overruling clear past precedent or deciding an issue of first impression, we must compare
DelCostello
with prior law. If
DelCostello
wrought “such an abrupt and fundamental shift in doctrine as to constitute an entirely new rule which in effect replaced an older one” on which Perez had relied, retroactive application may be inappropriate.
Hanover Shoe v. United Shoe Machinery Corp.,
When Perez’s cause of action arose, there was no clear past precedent on which Perez could reasonably rely in waiting twenty-three months to file his suit. The Supreme Court had not determined the statute of limitations applicable to
Vaca-Hines
actions. In
UAW v. Hoosier Cardinal Corp.,
In
Falsetti v. Local Union No. 2026, UMW,
It may well be, however, that at least in a case such as this, where the facts were susceptible of triggering National Labor Relations Board action on unfair labor practice grounds, that the state statute of limitations would cause undesirably lingering litigation in light of the six-months federal statute of limitations governing unfair labor practices.
Falsetti,
When his cause of action accrued, Perez was thus faced with case law in this circuit which, though leaving the issue open, foreshadowed
DelCostello’s
application of section 10(b)’s limitations period to
Vaca-Hines
actions. Perez contends nonetheless that the law in other circuits, and in the district courts, justified his delay of twenty-three months in filing his complaint. We find, however, that such case law decided the issue of the applicable statute of limitations erratically and inconsistently. Although other circuits had read
Hoosier Cardinal
as requiring the use of state statutes of limitations, their attempts to find state analogies had been so diverse and conflicting as to create “a legally chaotic situation,”
Lawson v. Truck Drivers Local Union 100,
If we consider the evolution of the law between the date Perez’s cause of action arose and the date he filed suit, we reach the same conclusion. During that interim period both this court in
Liotta
and the Supreme Court in
Mitchell
decided that an employee’s
Vaca-Hines
suit against his employer was governed not by state contract statutes of limitations but by state statutes of limitations for the vacation of arbitration awards.
Mitchell,
We conclude that Perez has not made the “threshold” showing that
DelCostello
established a new principle of law so as to bar its retroactive application to Perez’s claim.
Brown v. United States,
B. The Purpose of the DelCostello Ruling
We next examine whether retrospective operation of the Supreme Court’s ruling in
DelCostello
“will further or retard its operation.”
Chevron,
We believe that that balance is best struck if DelCostello is applied retroactively. Given the uncertainty that has characterized the borrowing of state statutes of limitations for Vaca-Hines actions, simple application of section 10(b)’s statute of limitations will serve to increase the uniformity of treatment among similar claims. More important, the imposition of the six-month limitations period will promote the finality of grievance-arbitration decisions and prevent the belated raising of claims after years have passed. Finally, the retrospective application of section 10(b) will not undermine the goal of providing adequate opportunity for the employee to vindicate his rights, for the Court has determined, in effect, that six months is long enough. We thus find that the second Chevron factor counsels in favor of retroactivity.
C. The Equities of Retroactive Application
Finally, we must consider whether application of
DelCostello
to Perez’s suit would be inequitable. In
Chevron,
the Court noted the harshness of applying a statute of limitations retroactively to deprive a plaintiff of any remedy whatsoever.
Ill
After examining the three Chevron factors, we conclude that, under the facts of this case, DelCostello should be applied retroactively to bar Perez’s claim. Perez fails to establish that DelCostello overruled clear precedent on which he may have relied, or decided a matter of first impression. Equally important, we find that the purpose of the DelCostello rule, and the equities of this case, impel retroactive application of that decision.
Consequently, the judgment of the district court will be affirmed.

(a) Suits for violation of contracts between an employer and a labor organization representing employees in an industry affecting commerce as defined in this chapter, or between any such labor organizations, may be brought in any district court of the United States having jurisdiction of the parties, without respect to the amount in controversy or without regard to the citizenship of the parties.

. In addition, Perez alleged that both the Company and the Union had violated Title VII of the Civil Rights Act of 1964, 42 U.S.C. §§ 2000e to 2000e-17 (1976 & Supp. IV 1980). The district court held that Perez’s failure to file a charge with the Equal Employment Opportunity Commission precluded consideration of the Title VII claim. Perez does not appeal that determination.
