We have accepted for interlocutory review a decision of the Superior Court which rejected a claim of collateral estoppel asserted by the appellant, Columbia Casualty Company (“Columbia”), against its former insured, Playtex FP, Inc. (“Playtex”). The Superior Court ruled that Playtex was not precluded from relitigating the issue of Playtex’s knowledge regarding the risk of toxic shock syndrome associated with the use of its super-absorbent tampons. Such knowledge was attributed to Playtex as a result of certain jury findings in a federal diversity action in Kansas. We agree with the Superior Court that the rendering jurisdiction’s requirement of mutuality of collateral estoppel must be given the same pre-clusive effect in Delaware, and accordingly affirm.

The facts giving rise to this dispute are essentially uncontroverted. On April 2, 1983, Betty O’Gilvie died of toxic shock
The trial court granted a partial remit-titur of punitive damages on the condition that Playtex remove its super-absorbent tampons from the market. The Court of Appeals, however, ruled that the District Court lacked authority to order a conditional remittitur and reinstated the original judgment. Playtex then appealed to the United States Supreme Court which denied certiorari.
In April, 1989, Playtex filed its Superior Court action against Columbia, seeking reimbursement for payments made by Playtex in response to toxic shock syndrome claims. 3 Playtex also alleged bad faith on the part of Columbia in denying coverage. Columbia counterclaimed for rescission of the insurance policy alleging that Playtex had fraudulently misrepresented the risk posed by tampons when it obtained insurance in 1984.
Relying on special interrogatory eight in the O’Gilvie action, Columbia moved to bar relitigation of the issue of Playtex’s knowledge of the risk of toxic shock syndrome from its super-absorbent tampons, based upon the doctrine of collateral estoppel. The Superior Court denied this motion. We accepted Columbia’s motion for interlocutory appeal to resolve this issue.

The doctrine of collateral estoppel is designed to provide repose and put a definite end to litigation.

See Tyndall v. Tyndall,
Del.Supr.,
Originally, many courts required mutuality to assert collateral estoppel. Mutuality requires a party attempting to bar an adversary from relitigating an issue to have been a party in the prior litigation or in privity with a party in the prior litigation.
See Bernhard v. Bank of America
Delaware, like many other jurisdictions, has abandoned the requirement of mutuality as a prerequisite to the assertion of collateral estoppel. “[T]he modern trend of decision and the rule in [Delaware], expands the use of the doctrine to situations where mutuality does not exist.”
Chrysler Corp. v. New Castle County,
Del.Super.,
No satisfactory rationalization has been advanced for the requirement of mutuality. Just why a party who was not bound by a previous action should be precluded from asserting it as res judicata against a party who was bound by it is difficult to comprehend. Many courts have abandoned the requirement of mutuality and confined the requirement of privity to the party against whom the plea of res judicata is asserted.
Bernhard,
The issue before us today, however, does not concern the effect of a prior Delaware judgment but involves the collateral estoppel effect to be given a judgment rendered by a federal district court in Kansas whose jurisdiction was based on diversity of citizenship. The question thus posed is essentially a choice of laws determination.
It is settled law in this jurisdiction that “the doctrines of res judicata and collateral estoppel require that the same effect be given a [foreign] judgment rendered upon adequate jurisdiction as [the foreign court] itself would accord such a judgment.”
Bata v. Hill,
Del.Ch.,
The principle enunciated in Bata controls the issue before us today. We find no distinction in the fact that Bata’s holding was directed to a judgment rendered by a court in another country as contrasted with a judgment rendered through the application of state law in a federal forum. Although founded on comity, the Bata principle is now one of sound judicial policy and requires that a Delaware court must give the judgments of another state court the same preclusive effect as would a court in that state.
Kansas requires mutuality of estoppel.
See McDermott v. Kansas Public Service Co.,
Columbia contends that the Superior Court erred in denying its motion for collateral estoppel for lack of mutuality because Delaware has abandoned the mutuality requirement. It is argued that the decision
While it is true that Delaware’s abandonment of the mutuality requirement was prompted by the desire to conserve judicial resources and promote finality,
see Coca-Cola Co. v. Pepsi-Cola Co.,
Del.Super.,
Comity permits one state to give effect to the laws of a sister state, not out of obligation, but out of respect and deference. 16 Am.Jur.2d,
Conflict of Laws
§ 10, at 28 (1979). Thus, “[a] cause of action arising under the laws of one state ... will not be enforced by another state as a matter of right but, rather upon principles of comity.”
Tyson v. Scartine,
Del.Super.,
Although the parties have debated the effect on this case of the full faith and credit clause, we view the issue as not dispositive.

U.S. Const., Art. IV § 1. “This provision requires every state to give to the judgments of another state, assuming jurisdiction by the state entering the judgment over the parties and subject matter, the same effect which that judgment has in the state in which it was rendered.”
Epstein v. Chatham Park, Inc.,
Del.Super.,
To the extent, however, that the mutuality requirement may be viewed as having its origin in Kansas decisional law, the interpretation of the full faith and credit clause advanced by Columbia would result in Delaware giving the judgments of a sister state greater preclusive effect than they would have in the rendering jurisdiction. For example, if Columbia attempted to bar relitigation of the issue of Playtex’s knowledge in a Kansas court, that effort would be rejected for lack of mutuality. If, on the other hand, mutuality were not required in the Superior Court action, the Kansas-based judgment would be given greater preclusive effect than received in the rendering jurisdiction. This result is clearly at variance with the purpose and spirit of the full faith and credit clause. Moreover, the resulting varying interpretations would again encourage forum shopping.

Finally, Columbia argues that a Delaware court should preclude relitigation of the jury finding in O’Gilvie because the Kansas federal district court that decided O’Gilvie would have applied federal law which does not require mutuality. We disagree and conclude that the law of the Tenth Circuit supports the application of state law.
Our reading of the law of the Tenth Circuit suggests that a federal district court sitting in diversity is required to apply state law in determining the preclusive effect of a prior judgment.
See Federal Insurance Co. v. Gates Learjet Corp.,
10th Cir.,
The Tenth Circuit determined that the District Court erred in failing to apply Michigan law to determine the collateral es-toppel effect of the Michigan state court judgment.
Gates,
The court then examined the preclusive effect to be given the determination of the Georgia district court. Relying on
Erie R.R. Co. v. Tompkins,
Thus, Tenth Circuit precedent compels the application of state law when a federal court sitting in diversity is called upon to determine the preclusive effect to give a prior judgment.
Gates,
Columbia argues that Guies’implicit recognition of state-based mutuality requirement was subsequently eroded by a later decision of the Tenth Circuit in
Petromanagement Corp. v. Acme-Thomas Joint Venture,
10th Cir.,

As an alternative argument, Playtex maintains that even if there is no legal bar to use of the jury finding in O’Gilvie, nonetheless, in the exercise of discretion the Superior Court should not permit the offensive use of such finding on considerations of fairness. The Superior Court found it unnecessary to address this issue, as do we. Moreover, we would decline to consider an issue not specifically decided by the trial court. Supr.Ct.R. 8.
In conclusion, we find Columbia cannot bar Playtex from relitigating the issue of its knowledge of the risk posed by tampons based on the doctrine of collateral estoppel because Columbia was not a party in the prior action nor in privity with a party and mutuality is required.

Notes
. "Toxic shock syndrome is a rare but serious and sometimes fatal disease associated with tampon use.” 21 C.F.R. § 801.430.
. Special interrogatory number eight, upon which Columbia bases its collateral estoppel claim, states:
8. Did International Playtex know, or should it have known, of the increased risk of developing toxic shock syndrome when using Playtex super deodorant tampons at the time of the death of Betty O'Gilvie?
Yes _X_ No_
. In 1984, Esmark, Inc., then the parent of Playtex, obtained umbrella liability coverage from Columbia for the policy year from October 1, 1984 to October 1, 1985. This policy expressly covered losses resulting from claims for injuries from toxic shock syndrome caused by Playtex tampons.
.The doctrine of collateral estoppel is related to the doctrine of res judicata. Collateral estoppel bars a party from relitigating a factual issue previously litigated, while res judicata bars a suit involving the same parties based on the same cause of action.
See Foltz v. Pullman, Inc.,
Del.Supr.,
. The full faith and credit clause of the United States Constitution provides:
Full Faith and Credit shall be given in each State to the public Acts, Records, and judicial Proceedings of every other State. And the Congress may by general Laws prescribe the Manner in which such Acts, Records and Proceedings shall be proved, and the Effect Thereof.
