Amanda L. BALL, Petitioner-Appellant,
v.
WILSHIRE INSURANCE COMPANY, a North Carolina Insurance Company, Defendant-Appellee.
No. 104,939.
Supreme Court of Oklahoma.
October 23, 2007.
Rick W. Bisher, Ryan Bisher Ryan, Oklahoma City, OK, for Plaintiff-Appellant.
Scott M. Rhodes, James W. Dobbs, Smith Rhodes Stewart & Elder, P.L.L.C., Oklahoma City, OK, for Defendant-Appellee.
WATT, J.
¶ 1 The United States Court of Appeals for the Tenth Circuit certified five questions[1] of Oklahoma law under the Revised *464 Uniform Certification of Questions of Law Act, 20 O.S.2001 §§ 1601, et seq. It is apparent from the materials accompanying the certification that the Tenth Circuit may refuse to exercise jurisdiction over the appeal.[2] Because this leaves any decision issued subject to being rendered a prohibited advisory opinion,[3] we decline to answer the questions certified.

RELEVANT FACTS
¶ 2 On August 22, 2006, the District Court for the Eastern District of Oklahoma issued an order in which the trial judge recognized that the plaintiff-appellant, Amanda L. Ball (Ball), filed a lawsuit alleging that she was an insured under a policy issued by the defendant-appellee, Wilshire Insurance Company (Wilshire/insurer). Ball alleged that Wilshire breached the insurance contract and acted in bad faith by refusing to defend and by failing to timely pay uninsured motorist coverage. The order also notes that on August 21, 2006, Ball and Wilshire filed a stipulation of dismissal, effectively closing the bad faith suit.[4] The stipulation of dismissal provides in pertinent part:
". . . The parties in this matter give notice . . . that Amanda Ball hereby dismisses without prejudice her remaining cause of action, breach of the UM contract, not previously disposed of by the Court by Summary Judgment. . . ." [Emphasis added.]
¶ 3 Ball filed a notice of appeal on September 15, 2006, asserting that the trial court's order of August 21st, resolving the final issues in the cause, made an earlier order, entered on April 4, 2006, final and appealable. Ball admits that the April 4th order dismissed all of her claims with the exception of her breach of contract claim regarding uninsured motorist coverage.[5]*465 On October 5, 2006, the Tenth Circuit issued its first order indicating that it was considering summary dismissal of the appeal for lack of jurisdiction. Ball was directed to file a brief on the issue of whether "the judgment of the district court [was] final and appealable where the appellant dismissed her remaining cause of action without prejudice."[6] [Emphasis provided.] Ball apparently sought an order from the trial court which issued on October 20, 2006, granting the motion for immediate certification of issues central to her bad faith claim. Noting the trial court's order, the Tenth Circuit issued an order on December 19th referring the jurisdictional issue to the panel assigned to hear the appeal on the merits.[7]
¶ 4 The Tenth Circuit's certification order was filed with this Court on August 20, 2007. On September 18, 2007, we issued an order indicating that an examination of the record revealed that the certifying court had reserved a jurisdictional issue for consideration on the merits. The parties were directed to file briefs showing cause why: 1) answers to the certified questions would not be advisory should the Tenth Circuit elect not to address the pending appeal on jurisdictional grounds; and 2) this Court should not exercise its discretion to refuse to answer[8] the questions certified as issues which may not be determinative of the cause. Briefing on the merits was completed on September 24, 2007, with the simultaneous filing of answer briefs by both parties. On September 28, 2007, Ball filed a brief in response to the show cause order. Wilshire's brief was filed on October 2, 2007.
Answering the questions certified is inappropriate where a decision by the certifying court to deny jurisdiction would render this Court's opinion advisory.
¶ 5 The insurer acknowledges that, if the Tenth Circuit denies jurisdiction, any opinion issued here would be advisory.[9] Ball urges us to answer the questions arguing that, even if the Tenth Circuit declines the appeal, our opinion would not be advisory as the questions certified are first impression and will settle an undetermined area of state law that will affect this case and all others with similar issues. We do not find Ball's arguments convincing and decline to answer the questions certified.
¶ 6 Pursuant to 20 O.S.2001 § 1602,[10] this Court has discretion[11] to answer a question of law within designated guidelines when properly certified by specific tribunals. The authority to answer such *466 questions is not universal. Rather, it extends only to those issues which may be determinative of the cause before the certifying court.[12]
¶ 7 We have elected not to answer questions certified in the past.[13] In Scottsdale Ins. Co. v. Tolliver, 2005 OK 93, 127 P.3d 611, we declined to do so where controlling Oklahoma precedent existed on the issue certified. The Court did not answer a certified question in Cray v. Deloitte Haskins & Sells, 1996 OK 102, 925 P.2d 60 where the trial court had made a judicial determination of an issue over which this Court had no judicial review. The Cray Court determined that because the ultimate issue of review would lie in the federal court, it was inappropriate to answer the question certified. On two other occasions, we have declined to answer all of the questions certified.[14]
¶ 8 Here, the certification puts us in the position of answering questions which may not be determinative of any issue in the cause. Just as we are under a duty to inquire into our own jurisdiction,[15] the Tenth Circuit must determine its jurisdiction to exercise its adjudicatory power.[16] If the Tenth Circuit determines that it will not hear the appeal, the answers proffered would be given *467 in the abstract.[17] The certification statute does not extend to the exercise of such judicial authority. Furthermore, to render answers to questions which may never be subject to review in the federal cause would result in our issuing a prohibited advisory opinion[18] concerning nothing more than a hypothetical situation.[19] This we will not do.[20]

CONCLUSION
¶ 9 The phrase indicating that a court "may" answer questions determinative of the cause has been included in statutes similar to Oklahoma's to ensure that answers to certified questions do not result in merely advisory opinions.[21] We are not prepared to utilize the certification process to resolve issues that will have, at best, a speculative impact in determining the underlying cause. To answer the questions here might arguably promote judicial economy of the Tenth Circuit in a single case, but it would not do so for this Court nor for the federal courts in general.[22] We determine that, under these particular circumstances, where the issue of jurisdiction remains unresolved in the federal court, it is inappropriate to answer the questions certified.[23]

ANSWERS TO QUESTIONS DECLINED.
WINCHESTER, C.J., EDMONDSON, V.C.J., HARGRAVE, KAUGER, WATT, TAYLOR, COLBERT, JJ. concur.
OPALA, J. dissents.
OPALA, J., dissenting.
¶ 1 I recede from the court's refusal to answer the questions certified to it by a federal court. Instead of declining to act, as the court does today, I would first inquire how the certifying court will resolve the federal-law issues that must be decided in advance of our answers. This is so because the federal court's resolutions of these questions will determine whether any state-law issues need be reached. If all of the state-law questions should stand eliminated, the certification could be withdrawn, but if some of them should retain viability, then an amended certification might be expected.
NOTES
[1]  As certified, the questions provide:

"1. Is a motor-vehicle-insurance-policy provision that excludes liability coverage for `Vehicles Loaned, Leased or Rented to others, including those dealerships and repair shops who provide [sec] while customer's auto is being repaired' void, in whole or in part, in light of Oklahoma's Compulsory Liability Insurance statute, Okla. Stat., tit. 47 §§ 7-600 to 7-612 (the Compulsory Insurance Law)?
2. If the answer to the first certified question is `yes,' does the exclusion nevertheless relieve an insurance company of its contractual duty to defend an insured?
3. If the answer to the second certified question is `no,' does an insurance company act in bad faith in relying on the exclusion to deny a defense to an insured?
4. If the answer to the first certified questions is `yes,' does the exclusion nevertheless apply to exclude uninsured/underinsured motorist coverage that was accepted by the named insured?
5. If the answer to the fourth certified question is `no,' does an insurance company act in bad faith in relying on the exclusion to deny or delay payment of uninsured/underinsured motorist benefits?"
[2]  On October 5, 2006, the Tenth Circuit issued an order for briefing providing in pertinent part:

". . . The court is considering summary dismissal of this appeal for lack of jurisdiction. . . .
JURISDICTIONAL ISSUE . . .
Whether the judgment of the district court is final and appealable where the appellant dismissed her remaining cause of action without prejudice. . . . "
On December 19, 2006, the Tenth Circuit issued an order providing in pertinent part:
". . . The court reserves judgment on the jurisdictional issue raised in this court's show cause order. The matter will be referred to the panel assigned to hear this appeal on the merits. . . . "
[3]  This Court does not issue advisory opinions or answer hypothetical questions. Scott v. Peterson, 2005 OK 84, ¶ 27, 126 P.3d 1232; City of Midwest City v. House of Realty, Inc., 2004 OK 56, fn. 14, 100 P.3d 678; Tulsa County Budget Bd. v. Tulsa County Excise Bd., 2003 OK 103, fn. 31, 81 P.3d 662.
[4]  The order, filed in the District Court for the Eastern District of Oklahoma, on August 22, 2006, providing in pertinent part at p. 2:

". . . Case no. CIV-05-491 is a civil action, originally filed in state court, in which Amanda Ball alleged that she was an insured under a policy issued by defendant Wilshire and that defendant breached the insurance contract and acted in bad faith by failing to defend and by failing to timely pay uninsured motorist (UM) benefits. . . .
On August 21, 2006, Amanda Ball and Wilshire filed a stipulation of dismissal, which effectively closes CIV-05-491. . . . "
[5]  Plaintiff-Appellant's Show Cause Brief, filed on September 28, 2007, providing in pertinent part at p. 2:

". . . The lower court's April 4, 2006 Order dismissed all Plaintiff/Appellant's claims with the exception of `Plaintiff's breach of contract claim regarding UM coverage.' If the court will recall, Appellee paid Ball and Sills UM limits after suit was filed and as noted by the Tenth Circuit, Appellant amended her bad faith claim to assert delay in paying UM benefits. . . . "
Admissions in a brief may be regarded as a supplement to the appellate record. Matter of Adoption of M.J.S., 2007 OK 43, fn. 17, 162 P.3d 200; King v. King, 2005 OK 4, fn. 31, 107 P.3d 570; Keating v. Edmondson, 2001 OK 110, fn. 21, 37 P.3d 882.

[8]  We have elected to decline to answer questions certified in a number of causes. Scottsdale Ins. Co. v. Tolliver, 2005 OK 93, 127 P.3d 611 [Declined to answer certified question where controlling Oklahoma precedent existed on the issue certified.]; Hammock v. United States, 2003 OK 77, 78 P.3d 93 [Declined to answer one of two certified questions because of lack of legal relationship necessary to determine the issue.]; Bituminous Casualty Corp. v.

Deloitte Haskins & Sells, 1996 OK 102, 925 P.2d 60 [Declined to answer certified question since federal judge made final determination on issue of duty such that Supreme Court was without judicial authority to either affirm or reverse that judgment.].
[9]  The insurer also asserts that we should decline to answer the questions certified as it has met all duties it owes to Ball. Our decision not to answer the questions certified makes any comment on these assertions unnecessary.
[10]  Title 20 O.S. 2001 § 1602 providing in pertinent part:

"Power to Answer. The Supreme Court . . . may answer a question of law certified to it by a court of the United States . . . if the answer may be determinative of an issue in pending litigation in the certifying court and there is no controlling decision of the Supreme Court or Court of Criminal Appeals, constitutional provision, or statute of this state."
