PUBLIC CITIZEN, Appellant,
v.
INSURANCE SERVICES OFFICE, INC., et al., Appellees.
No. 3-91-147-CV.
Court of Appeals of Texas, Austin.
February 26, 1992.
Karl Bayer, Austin, Cornish F. Hitchcock, Washington, D.C., for appellant.
Tim Gavin, Carrington, Coleman, Sloman & Blumenthal, Dallas, for appellees.
Before CARROLL, C.J., and JONES and BEA ANN SMITH, JJ.
*812 CARROLL, Chief Justice.
Following the settlement of an antitrust suit by the State of Texas and several insurance companies,[1] Public Citizen, a consumer-advocate group, filed a motion to intervene and a motion to vacate a protective order. See Tex.R.Civ.P.Ann. 76a (Supp.1991). The trial court granted the motion to intervene but denied the motion to vacate the protective order. Public Citizen appeals the denial of its motion to vacate the protective order. We affirm the order of the trial court.

THE CONTROVERSY
In 1988, the State of Texas filed an antitrust action against several insurance companies. To expedite discovery, the parties agreed to conduct discovery under an agreed protective order. That order permitted any party to designate as "confidential" any document which the party believed to contain information that could be protected under Rule 166b(5). See Tex. R.Civ.P.Ann. 166b(5) (Supp.1991). The order restricted access to the documents to certain individuals and forbade the use or disclosure of the documents for any purpose except for preparing, trying and appealing the antitrust suit.
In 1990, the Supreme Court of Texas promulgated Texas Rule of Civil Procedure 76a, which provides guidelines and procedures for sealing court records. Tex.R.Civ. P.Ann. 76a (Supp.1991). Rule 76a(9) states that the new rule applies to "all court records filed or exchanged after the effective date" and to "any motion to alter or vacate an order restricting access to court records, issued before the effective date." Tex.R.Civ.P.Ann. 76a(9)(a), (b) (Supp.1991). The effective date of the rule was September 1, 1990.
On November 1, 1990, the State filed a motion asking the district court to vacate the agreed protective order because Rule 76a established a presumption that court records are to be open to the public. The State contended the Companies had abused the protection of the order by misrepresenting the contents of the documents, which, of course, were unavailable for verification by the terms of the order. The State argued that the Companies should have to follow the procedures set out in Rule 76a to assure that the records remain sealed. See Tex.R.Civ.P.Ann. 76a(3-6) (Supp.1991).
The district court held a hearing on the State's motion on December 7, 1990. Public Citizen had advance notice of the hearing and had a representative present at the hearing, but did not participate in the proceeding. On December 14, 1990, the district court issued an order which granted the State's motion in part, vacating the protective order as to documents filed after September 1, 1990. The court denied the motion as to documents filed before September 1, 1990, thereby maintaining the protective order with respect to documents filed before the effective date of Rule 76a.
On December 18, 1990, Public Citizen filed several motions in connection with the court's ruling. It sought to intervene in the suit, alleging that it was entitled to do so by virtue of Rule 76a(7), and also moved to vacate the protective order to the extent it allowed the records to remain sealed. Relying on Rule 76a(9), Public Citizen argued that the court should unseal all records except those specific documents demonstrated by the Companies to fall within the exceptions to disclosure set out in Rule 76a(l).
The district court heard argument on the motions in January 1991. During that hearing the court granted Public Citizen's motion to intervene, but took the motion to vacate the protective order under advisement. In February 1991, the court denied the motion to vacate the protective order without explanation.
*813 In a single point of error, Public Citizen contends the district court erred in failing to follow the procedures set forth in Rule 76a and in denying Public Citizen's motion to vacate the protective order. In a cross point, the Companies respond that Public Citizen may not challenge the district court's order on appeal because they were not entitled to intervene in this action.

DISCUSSION
The parties advance sharply different contentions regarding the applicability of Rule 76a. Public Citizen maintains that Rule 76a governs its cause of action and provides a mechanism for intervention. Public Citizen also argues that, because the hearing below was based on Rule 76a, it has a right to appeal and to urge that the trial court erred by failing to vacate the protective order. The Companies, on the other hand, contend that the district court hearing was not a Rule 76a hearing, and that Rule 76a gives Public Citizen no right to intervene or to secure relief by appeal. We need not resolve these competing claims, however, because we conclude that Public Citizen is an "intervenor who had actual notice" and is precluded from challenging the trial court's ruling under the express provisions of Rule 76a(7):
Any person may intervene as a matter of right at any time before or after judgment to seal or unseal court records.... An order sealing or unsealing court records shall not be reconsidered on motion of any party or intervenor who had actual notice of the hearing preceding issuance of the order, without first showing changed circumstances materially affecting the order.
Tex.R.Civ.P.Ann. 76a(7) (Supp.1991) (emphasis added). Public Citizen concedes that it had a representative at the December 7 hearing on the State's motion to vacate the protective order. By the terms of Rule 76a(7), Public Citizen had no right to a reconsideration of the motion to vacate.
We believe that Rule 76a(7) prevents an interested non-party such as Public Citizen from waiting on the sidelines until a court issues an order, and then, if dissatisfied with the outcome, intervening and forcing the parties and court to relitigate the issue.

CONCLUSION
We overrule Public Citizen's point of error. Therefore, we need not address the Companies' cross-point complaining of the trial court's order allowing Public Citizen to intervene. We affirm the order of the trial court.
