Appellant contends that
Azzarello v. Black Bros. Co.,
*576 Appellee Arlene B. Leland was employed as a laboratory technician at a Philadelphia hospital. Her duties included cleaning utensils in reagent grade sulfuric acid manufactured by appellant. On December 11, 1964, appellee obtained two glass bottles of this acid from a store-room. When she returned to her station, Mrs. Leland placed one of the one-gallon bottles onto the counter. While lifting the other, she heard the sound of breaking glass. The next thing she remembered was lying on the floor in a. pool of sulfuric acid. Mrs. Leland testified that she did not strike the bottle against the counter top, that she did not see the bottle break, and that she believed that it had broken spontaneously in mid-air.
In December, 1966, appellees instituted this action, asserting, inter alia, that appellant was strictly liable under the Restatement (Second) of Torts § 402A (1965). 1 At the trial, which commenced on January 22, 1975, 2 appellees’ expert witness opined that the glass bottle was defective and could have broken spontaneously because of internal stresses, improper annealing, or minute scratches on the surface of the glass, each of which might have weakened the bottle. The expert testified also that the product was not packaged safely because there was technology available in 1964 to provide secure packaging for such a potentially lethal product. Thus, appellees asserted alternative theories of defectiveness. After the jury returned a unanimous verdict for appellant, appellees filed a motion for a new trial or judgment n. o. v. The lower court granted the motion for a new trial. This appeal followed.
At the time of trial, Pennsylvania law required that a plaintiff in a products liability case based upon strict liability prove that the “product [was] in a defective condition
*577
unreasonably dangerous
to the user or consumer . . . . ” Restatement (Second) of Torts § 402A (1965) (emphasis added).
See Webb
v.
Zern,
If you find that an unsafe and improper use of the product was the legal cause of the accident rather than any alleged defective condition, then you must find for the defendant. But, if you find that the product was defective, and that the defect was the legal cause of an unreasonable danger resulting in injury to the plaintiff, then you must find for the plaintiff.
Appellees repeatedly excepted to that charge and based their motion for a new trial upon the ground that the “unreasonably dangerous” language had no place in a jury charge on the issue of strict liability. After appellees’ motion was filed but before it was determined, our Supreme Court decided
Berkebile v. Brantly Helicopter Corp.,
For the term guarantor to have any meaning in this context the supplier must at least provide a product which is designed to make it safe for the intended use. Under this standard, in this type of case, the jury may find a defect where the product left the supplier’s control lacking any element necessary to make it safe for its intended use or possessing any feature that renders it unsafe for the intended use. It is clear that the term “unreasonably dangerous” has no place in the instructions to a jury as to the question of “defect” in this type of case. We therefore agree with the court en banc that the use of the term “unreasonably dangerous” in the charge was misleading and that the appellee was entitled to a new trial.

Azzarello v. Black Bros. Co., supra 480
Pa. at 559-60,
Appellant contends that Azzarello should not be retroactively applied. We disagree.
It is the settled common law tradition that judicial precedents normally have retroactive as well as prospective effect. That is, what the court holds to be the law for today for the litigants before it, is the law for persons who come into court hereafter, even though the alleged wrong was committed before today’s decision, and today’s decision declares illegal what appeared to be legal when it was done.

Accordingly, our cases have held, in a variety of contexts, that an intervening change in the law must be applied to cases which are in the throes of direct appeal when the change occurred.

Kuchinic v. McCrory,
*579 While there are no cases in Pennsylvania dealing with the effect of a change in decisional law pending appeal, there is authority in a closely related field. Unless vested rights are affected, a court’s interpretation of a statute is considered to have been the law from its enactment date, despite contrary intervening holdings. Buradus v. General Cement Prods. Co.,159 Pa.Super. 501 ,48 A.2d 883 (1946), aff’d356 Pa. 349 ,52 A.2d 205 (1947). In such circumstances, the latest interpretation is applicable to a ease whose appeal has not yet been decided.
Moreover, there are occasions when a party is given the benefit of a change in the law in order to prevent an injustice, especially when, as here, the other party could not have changed his position in reliance on the initial decision. Thus in Reamer’s Estate,331 Pa. 117 ,200 A. 35 (1938), we were willing to correct a decision in a previous appeal of the same case which had been made palpably erroneous by an intervening decision despite the law of the case doctrine. Recently in Brubaker v. Reading Eagle Co.,422 Pa. 63 ,221 A.2d 190 (1966), we ordered a new trial to permit the plaintiff to bring his allegations within the actual malice requirement of New York Times Co. v. Sullivan,376 U.S. 254 ,84 S.Ct. 710 [,11 L.Ed.2d 686 ] (1964). Although in Brubaker, the plaintiff was deprived of his original verdict by the change in law, and it thus is the converse of the present problem, it is illustrative of our goal of assuring each litigant a fair adjudication on the merits.
We recognize that various inequities arise in all three standards [which determine the effective date of a decision] when one litigant benefits from a decision and another, seemingly similarly situated, is denied the same benefit. We are of the opinion that the Little-Linkletter finality approach, which was first announced in United States v. Schooner Peggy,1 Cranch 103 , [5 U.S. 103 ],2 L.Ed. 49 (1801), should remain as the standard for issues of applicability in this Commonwealth. 6
Thus, we hold that the lower court correctly applied Azzarello retroactively. 7

Appellant also argues, citing
Chevron Oil Co. v. Huson,
Order affirmed.

United States v. Schooner Peggy,
1 Cranch (5 U.S.) 103, 110,
It is, in the general, true that the province of an appellate court is only to inquire whether a judgment, when rendered, was erroneous or not. But if, subsequent to the judgment, and before the decision of the appellate court, a law intervened and positively changes the rule which governs, the law must be obeyed, or its obligation denied. If the law be constitutional, and of that no doubt, in the present case, has been expressed, I know of no court which can contest its obligation.... In such a case, the court must decide according to existing laws, and if it be necessary to set aside a judgment, rightful when rendered, but which cannot be affirmed, but in violation of law, the judgment must be set aside.
. There are many sound reasons for applying judicial pronouncements retroactively. As one writer has stated:
On the basis of public policy and fairness, retroactive overruling is the most equitable approach in the area of tort law. The arguments supporting this view are clear and numerous. First, it is not necessary to use the prophylactic doctrine of prospective overruling in the tort area since reliance is generally not a viable argument. Second, by applying the new law to the case before the court, the policy of providing incentive for challenging outmoded legal doctrines is served. Third, the fear that the new rule becomes pure dicta if it is not applied to the case before the court is eliminated. Finally, applying the new rule to cases still in the judicial process promotes the interests of fairness and judicial administration. By accepting review of cases that reach the court after a change in the law, the court avoids the cumbersome task of deciding cases under the old law after the rejection of that law. Because of the delays in legal process, discredited rules of law live on for many years under prospective overruling.

. Assuming,
arguendo,
that
Chevron Oil
properly applies to common law actions in tort, appellant misconstrues its effect. Appellant suggests that
Chevron Oil
sets forth a tripartite test which must be met before a decision may be retroactively applied. On the contrary, we read
Chevron Oil
to require retroactive application unless each of the enumerated criteria are present.
. Interestingly, appellant does not argue that Webb v. Zern, supra, should not be retroactively applied.
. Appellant raises three additional issues which lack merit.
Appellant contends that appellees are not entitled to a new trial because the four year delay in disposing of appellees’ motion for a new trial is presumptively prejudicial to it. Although appellant strenuously argues that justice should not be delayed, the case upon which it principally relies states that “a lapse of time is presumptively prejudicial to
all
parties,” not only the party opposing a motion for a new trial.
Shrum v. Pennsylvania Electric Co.,
Appellant next contends that the jury was properly charged under Azzarello. Because the jury was charged in terms of “unreasonable danger,” and because Azzarello holds that it is reversible error to use negligence terms in a strict liability instruction, this contention is meritless.
Appellant finally contends that Azzarello should not be applied to a case involving conscious design choices. We decline to so limit Azzarello. The Supreme Court did not expressly limit its holding to cases involving manufacturing and/or design defects. Indeed, were we to adopt the rule urged by appellant, we would only compound the confusion created by the “unreasonably dangerous” standard in cases such as this which involve both manufacturing defects and conscious design defects.
