201 S.W.3d 739 (2006)
The STATE of Texas
v.
Cameron O. BAILEY, Appellant.
Nos. PD-1955-04 to PD-1957-04.
Court of Criminal Appeals of Texas.
September 20, 2006.
*740 Stephen Wohr and Katy Klinke, Denton, for Appellant.
Larissa T. Roeder, Assistant District Atty., Dallas, Matthew Paul, State's Atty., Austin, for State.

OPINION
MEYERS, J., delivered the opinion for a unanimous Court.
In 2002, the State charged Appellant Cameron O. Bailey with three violations of the Texas Securities Act. In a consolidated trial, the jury found him guilty of selling unregistered securities (cause number F02-00019-T), selling securities without being a registered securities salesperson (cause number F-02-00035-T), and engaging in fraud in the sale of securities (cause number F02-00037-T). The trial judge sentenced Appellant to five years' confinement and a $1000 fine on the first two indictments and eight years' confinement and a $5000 fine on the third indictment.
On appeal, Appellant claimed that the certificates of deposit at issue were not securities under the Texas Securities Act as a matter of law and that the trial court had erred in finding otherwise. The Eighth Court of Appeals concluded that "whether a nominal certificate of deposit is or is not a security . . . depends on the facts and the determination of that issue must be left to a jury." Bailey v. State, 155 S.W.3d 346, 348 (Tex.App.-El Paso 2004). It then re-framed Appellant's complaint to be that "the trial court erred in charging the jury that the certificates of deposit in this case were securities." The court of appeals sustained this sole issue and remanded the case for a new trial.
The State petitioned from the holding of the court of appeals, and we granted the following grounds for review: 1) Did the court of appeals err in finding jury charge error where the Appellant affirmatively requested the trial court and not the jury decide the issue on which the reversal is based? 2) Did the court of appeals err in finding jury charge error where the Appellant failed to object to the error at trial? 3) Did the court of appeals err in finding jury charge error where the Appellant did not argue the ground at trial or present it as a point on appeal? The issue on appeal had been whether the trial court made a proper determination that the certificates of deposit at issue were securities as a matter of law, not whether it properly charged the jury. Because the court of appeals resolved the case under a theory that Appellant did not raise at trial or on appeal, we hold that the court of appeals erred and remand the case so that it can address the arguments briefed by the parties.


*741 Facts
In 1998, Appellant began working as a salesperson at Cornerstone Financial, where he sold purported high-yield certificates of deposit (CDs) on behalf of Cambridge International Bank of Grenada. Cambridge is a subsidiary of Royal Bank and Trust of Zurich A.G., a Swiss trust company operating out of the West Indies, and it is not registered to conduct banking business in the United States or to sell securities in Texas. Although Appellant claimed in newspaper advertisements and in the prospectus given to potential investors that the CDs were insured, there was in fact no federal or private insurance securing investments in these instruments. Furthermore, Appellant was not registered to sell securities in Texas, and in 1999, the Texas Securities Board began investigating him for alleged illegal sales of viatical contracts, which it advised him were securities. In 2000, Cornerstone Financial shut down, and the certificates of deposit that had been sold to investors were never repaid in full. In 2002, the State brought criminal charges against Appellant in three separate indictments for (1) selling unregistered securities; (2) selling securities without being a registered securities salesperson; and (3) engaging in fraud in the sale of securities.
At trial, defense counsel contended that Appellant had been improperly indicted because the certificates of deposits which he had sold to investors did not fall under the definition of securities under the Texas Securities Act.[1] Because there was no controlling Texas or federal caselaw on the issue, defense counsel argued that the trial judge should decide whether the certificates of deposit constituted securities as a matter of law. The State agreed to this request, and both parties reserved their right to challenge the trial judge's determination. The State then put on its expert witness, the director of the Enforcement Division for the Texas Securities Board, outside the presence of the jury.[2] The witness testified that the certificates of deposit in this case qualified as securities under the Act's definition because they were "evidence of indebtedness" and "investment contracts." In issuing his opinion, the expert relied on the Texas Supreme Court case, Searsy v. Commercial Trading Corp., 560 S.W.2d 637 (Tex.1977), and the United States Supreme Court case, S.E.C. v. W.J. Howey Co., 328 U.S. 293, 66 S.Ct. 1100, 90 L.Ed. 1244 (1946), and the definitions and the tests outlined *742 therein. In its charge to the jury, the court instructed that the certificates of deposit were securities under the Texas Securities Act[3] and the jury should find Appellant guilty if the State had proved the other elements of the offenses beyond a reasonable doubt. After the jury determined Appellant's guilt, the trial judge imposed fines and confinement for each of the offenses.

Court of Appeals
On appeal, Appellant's sole claim involved "whether the trial court erred in finding as a matter of law that a certificate of deposit is a security within the meaning of the Securities Act." In his brief, Appellant submitted that the Texas Securities Act did not include certificates of deposit within its definition of securities and that no Texas case had defined a certificate of deposit as a security. Appellant also argued that the certificates of deposit at issue did not fall into any of the "uncommon or irregular instruments" provisions of the statute, such as evidence of indebtedness or an investment contract, because they did not meet any of the various tests established by the United States Supreme Court for these categories.
The State argued that the trial judge had not erred in making his determination as a matter of law. In its brief, it contended that the certificates of deposit at issue fell within the definition of a security as "an interest in any or all of the capital, property, assets, profits or earnings of any company, investment contract, or any other instrument commonly known as a security, whether similar to those herein referred to or not." The State also cited federal and state cases in support of the trial judge's determination and examined the certificates of deposit under the tests enunciated by the United States Supreme Court for establishing a financial instrument as a security, concluding that the CDs met the requirements.
Instead of considering Appellant's complaint that the trial judge had erred in concluding that the CDs were securities as a matter of law, the court of appeals determined that a certificate of deposit's qualification as a security was a fact question that should have been put to the jury with appropriate instructions. Based on this conclusion, the court of appeals re-framed Appellant's issue, citing to Texas Rules of Appellate Procedure 38.1 and 38.9,[4] and held that the trial court had erred in submitting its jury charge. The court of appeals remanded the case for a new trial.

Issue Granted
The State filed a petition for discretionary review, arguing that the court of appeals erred in finding jury charge error because: 1) the Appellant affirmatively requested the trial court and not the jury decide the issue on which the reversal is based; 2) the Appellant failed to object to the error at trial; and 3) the Appellant did not argue the ground at trial or present it as a point on appeal. We granted review on these grounds, and we hold that the court of appeals committed error when it addressed an issue not presented to the trial court or raised by the parties on appeal.


*743 Analysis
We have held that it violates "ordinary notions of procedural default" for a court of appeals to reverse a trial court's decision on a legal theory that the complaining party did not present to the trial court. Hailey v. State, 87 S.W.3d 118, 122 (Tex.Crim.App.2002) (citing State v. Mercado, 972 S.W.2d 75, 77-78 (Tex.Crim.App. 1998)). Accordingly, we have established that an appellate court may not reverse a trial court "on a theory that the trial court did not have the opportunity to rule upon and upon which the non-appealing party did not have an opportunity to develop a complete factual record." Hailey v. State, 87 S.W.3d at 122 (citing Posey v. State, 966 S.W.2d 57, 62 (Tex.Crim.App.1998)). In the instant case, the parties agreed that the trial judge would decide whether the certificates of deposit at issue met the definition of a security under the Texas Securities Act as a matter of law.[5] Their agreement precluded the trial judge from making a determination on whether the issue was a question of law or a question of fact.
In addition, we have established that it is improper for an appellate court to reverse a case on a theory not raised at trial or on appeal. Hailey v. State, 87 S.W.3d at 118; Gerron v. State, 97 S.W.3d 597 (Tex.Crim.App.2003) (per curiam). On appeal, Appellant continued to claim that the certificates of deposit in question were not securities under the Texas Securities Act as a matter of law. Appellant never argued that it was the province of the jury to determine whether the certificates of deposit were securities. The issue upon which the court of appeals reversed the trial court was not before it.
In "re-fram[ing]" Appellant's complaint on appeal, the court of appeals relied on two provisions of the Texas Rules of Appellate Procedure. Citing Rules 38.1 and 38.9, it reformulated the issue to be that the trial court erred in charging the jury that the CDs were securities. It then reversed the trial court on this ground. We find no support for the court of appeals' position under these provisions. Rule 38.1 deals with the requirements an appellant must meet in preparing his brief for the court, and Appellant satisfied all of them in submitting his brief to the Eighth Court of Appeals. Although Rule 38.1(e) explains that "the statement of an issue or point [presented for review] will be treated as covering every subsidiary question that is fairly included," the issue of who should make the determination of whether CDs qualify as securities under the Texas Securities Act is clearly separate from whether the trial judge in this case, in response to the agreement of the parties, erred in deciding that the CDs in question were securities as a matter of law. Rule 38.9 instructs that the briefing rules are to be *744 construed liberally, allowing the appellate court to "require additional briefing, and make any other order necessary for a satisfactory submission of the case" if it "determines. . . that the case has not been properly presented in the briefs, or that the law and authorities have not been properly cited in the briefs." TEX.R.APP. PROC. 38.9(b). While this provision gives the appellate courts some discretion in remedying "substantive defects" in parties' briefs, it does not allow the court of appeals to reach out and reverse the trial court on an issue that was not raised.

Conclusion
The court of appeals reversed this case on an issue that was neither ruled upon by the trial court, nor raised on appeal. Its discretion does not extend so far. In the instant case, the court of appeals should have answered the question posed by Appellant on appeal. We sustain the State's third ground for review, making it unnecessary to address its other grounds for review, which we dismiss. The judgment of the court of appeals is reversed, and the case is remanded for resolution of whether the CDs in the instant case qualify as securities under the Texas Securities Act as a matter of law.
NOTES
[1]  The definition of security in the Texas Securities Act is contained in TEX.REV.CIV. STAT. art. 581-4. It states that "[t]he following terms shall, unless the context otherwise indicates, have the following respective meanings":

A. The term "security" or "securities" shall include any limited partner interest in a limited partnership, share, stock, treasury stock, stock certificate under a voting trust agreement, collateral trust certificate, equipment trust certificate, preorganization certificate or receipt, subscription or reorganization certificate, note, bond, debenture, mortgage certificate or other evidence of indebtedness, any form of commercial paper, certificate in or under a profit sharing or participation agreement, certificate or any instrument representing any interest in or under an oil, gas or mining lease, fee or title, or any certificate or instrument representing or secured by an interest in any or all of the capital, property, assets, profits or earnings of any company, investment contract, or any other instrument commonly known as a security, whether similar to those herein referred to or not.
[2]  Earlier in the trial, the jury heard the testimony of the State's other expert witness, William Kerr, a National Bank Examiner with the Office of the Comptroller of the Currency, who testified that Cambridge Bank was an offshore bank that was not approved to do banking in the United States and that there was no deposit insurance or other security to protect that bank's deposits. See Bailey, 155 S.W.3d at 348.
[3]  The relevant portion of the jury charge read: "You are instructed that the term `security' or `securities' shall include an evidence of indebtedness, or investment contract, or any other instrument commonly known as a security whether similar to those herein referred to or not. You are instructed that documents described herein as a certificate of deposit . . . are securities."
[4]  TEX.R.APP. PROC. 38.1, 38.9 (Vernon 2004).
[5]  Following a discussion of Appellant's trial claim that the CDs in question were not securities as a matter of law, the court took a brief recess. When the court came back to order, the trial judge stated:

It is my understanding that the lawyers and the parties to the case have agreed to have the Court consider the testimony of the expert witness, David Grauer, outside the presence of the jury, and . . . make a legal finding as to the instrument at issue in each of the three cases being stated in the indictment as a Certificate of Deposit . . . being a security covered by the Securities Act or not being a security covered by the Securities Act and so instruct the jury in the Court's charge on this point.
Both sides observed the right to object to and take exception to the Court's ruling but agree to the Court making the finding at this point.
The State's attorney, defense counsel, and Appellant indicated that the judge's remarks correctly reflected their understanding of the agreement.
