OPINION OF THE COURT
I. FACTUAL AND PROCEDURAL HISTORY
This case.is before this court
on
appeal from an order of the district court entered April 1, 1996, which affirmed an order of the bankruptcy court entered July 19, 1995, for the reasons the bankruptcy court set forth in its opinion. Insulfoams, Inc., the debtor, was incorporated in Pennsylvania in 1979 and was in the business of installing insulation for commercial and industrial establishments. Defendants-appellants, Dennis and Marion Donaldson, were Insulfoams’ only shareholders, directors and officers, and at least at one time, each owned half of its stock. Dennis was Insulfoams’ President and chief executive officer and Marion was its chief financial officer. According to the Donaldsons, Marion resigned her office and sold her stock in Insulfoams on April 5, 1990. Br. at 15-16. The Donaldsons, however, did not disclose the resignation and sale until Dennis notified the Pennsylvania Department of State Corporations Bureau in May 1994. In its opinion following the trial, the bankruptcy court rejected the Donaldsons’ contentions that Marion had resigned and thus treated her as an officer of Insulfoams at all times material to this action.
In re Insulfoams,
Insulfoams filed a voluntary Chapter 11 bankruptcy petition on April 24, 1989, and thereafter continued operations as a debtor-in-possession. On October 26, 1989, Insul-foams filed a disclosure statement and plan of reorganization, But, as the bankruptcy court explained in its opinion, the court required Insulfoams to file an amended disclosure statement indicating whether the Don-aldsons would make a future cash infusion into Insulfoams.
Insulfoams,
The bankruptcy court approved the amended disclosure statement on April 12, 1990, and confirmed Insulfoams’ plan of reorganization on May 24, 1990. The plan required Insulfoams to pay its tax liabilities to the Internal Revenue Service ($29,893) and the State of Pennsylvania ($6,346.74) in full, with interest, over the first 20 months of the plan. Supp. app. at 85. The Donaldsons were personally liable for these taxes. The plan further provided that Insulfoams would *551 pay the unsecured creditors’ claims (totaling $284,250) 30 cents on the dollar in monthly payments running from the 21st month to the 72nd month of the plan. Id. The court issued a final decree on April 2, 1991, after Insulfoams represented that the plan had been substantially consummated, and the clerk of the bankruptcy court closed the case six months later on October 2,1991.
On September 29, 1992, Insulfoams’ largest unsecured creditor filed a motion to compel it to make payments according to the plan, alleging that Insulfoams had not made any payments to the unsecured creditors after completing the payments to the IRS and the State of Pennsylvania. Insulfoams admitted the allegations, but claimed that adverse business conditions caused it to miss the payments and indicated that it would meet its plan obligations by December 15, 1992. In these circumstances, the bankruptcy court postponed a hearing on the creditor’s motion until December 15, 1992, but at that time it found that Insulfoams would not be able to make the required payments. Consequently, the bankruptcy court reopened the case pursuant to 11 U.S.C. § 350(b) and converted it to a Chapter 7 proceeding pursuant to 11 U.S.C. § 1112(b)(8).
The court appointed a trustee for Insul-foams on December 22, 1992. On July 31, 1994, the trustee brought this adversary proceeding in the bankruptcy court against the Donaldsons, alleging that they obtained com firmation of the reorganization plan under false pretenses, knowing that they would not fund the plan after they paid the tax debts for which they were personally liable. The trustee further charged that the Donaldsons breached their fiduciary duties to Insulfoams by diverting business opportunities from it to Hi-Tech Contractors, Inc., another company they owned, for their personal benefit. The trustee sought compensatory and punitive damages against the Donaldsons.
The evidence at the trial showed that Hi-Tech was founded in the mid-1980s and that Dennis Donaldson was its principal. Hi-Tech was in the business of removing asbestos and other hazardous materials, for which it, unlike Insulfoams, was properly licensed and insured. Insulfoams and Hi-Tech leased adjoining space in a building the Donaldsons owned and often used the same employees and equipment. In 1992, Insulfoams had seven contracts (totaling $181,098.69) for the removal of asbestos and other hazardous materials which it subcontracted to Hi-Tech. Insulfoams received $12,047.01 of the profits from these contracts, while Hi-Tech received $29,672.62.
Insulfoams,
II. DISCUSSION
A. Standard of Review
Inasmuch as the district court sits as an appellate court in bankruptcy proceedings, we exercise plenary review of its decision.
In re Swedeland Dev. Group, Inc.,
B. Subject Matter Jurisdiction
The Donaldsons argue that the bankruptcy court did not have subject matter jurisdiction because prior to the commencement of these adversary proceedings the court closed the case after a final decree. The bankruptcy court, however, did more
*552
than entertain this adversary proceeding. Rather, before the trustee instituted these proceedings, the court reopened the ease pursuant to 11 U.S.C. § 350(b) and converted it to a Chapter 7 ease pursuant to 11 U.S.C. § 1112(b)(8). Only then did it appoint the trustee. Section 350(b) provides that “[a] case may be reopened in the court in which such case was closed to administer assets, to accord relief to the debtor, or for other cause.” Here, the court reopened the case “for other cause,” namely the Donaldsons’ material default with respect to implementing the plan of reorganization, a basis to convert a post-confirmation Chapter 11 case to a Chapter 7 case under 11 U.S.C. § 1112(b)(8). While no party sought the reopening, 11 U.S.C. § 105(a) empowered the bankruptcy court to reopen the case on its own motion. See
In re Doty,
The Donaldsons, however, expand on their subject matter jurisdiction argument as they contend that the confirmation of the plan in itself, an act distinct from closing the Chapter 11 case, eliminated the bankruptcy court’s jurisdiction to entertain this proceeding. In this regard, they point out that the trustee essentially bases this adversary proceeding on state law claims. Furthermore, they note that this proceeding deals mainly with events in 1992, two and a half years after the bankruptcy court approved the reorganization plan and that the events even took place after the bankruptcy court closed the case on October 2, 1991. The Donaldsons observe that there is a division of authority with respect to the scope of a bankruptcy court’s jurisdiction following confirmation of a plan. Thus, some courts have ruled that jurisdiction exists after confirmation of a plan only for those matters expressly reserved by the confirmation.
See, e.g., In re Johns-Manville Corp.,
We, however, need not decide the general scope of a bankruptcy court’s jurisdiction following the confirmation of a plan, for at a minimum it would have jurisdiction over a case otherwise within its jurisdiction under 28 U.S.C. § 1334 if, as here, the court has reopened a case after confirmation and converted it to a Chapter 7 case.
See Walnut
Assocs.
v. Saidel,
We consider then the extent of a bankruptcy court’s jurisdiction under 28 U.S.C. § 1334. The fact that we have concluded a court has not lost its jurisdiction here because of the case’s procedural posture does not mean that the court can entertain any matter tendered to it. Rather, a bankruptcy court can act only in cases and proceedings within its jurisdiction. Bankruptcy courts have original jurisdiction over: (1) cases under Title 11; (2) proceedings arising under Title 11; (3) proceedings arising in a case under Title 11; and (4) proceedings related to a case under Title 11. 28 U.S.C. § 1334. A case under Title 11 is the bankruptcy petition itself, a basis for jurisdiction clearly not applicable here. A proceeding fitting within any of the three remaining categories is within the bankruptcy court’s jurisdiction and, since the third category is the broadest, a court “need only determine “whether a matter is at least related to the bankruptcy.’”
In re Marcus Hook Dev. Park, Inc.,
Some courts have held that the act of confirmation changes the above test to mean “significantly affect consummation of the plan as confirmed.”
In re Haws,
This proceeding, however, is different in several respects from these cases limiting a bankruptcy court’s jurisdiction. First, this proceeding has a much closer nexus to the bankruptcy case than the proceedings in
Haws, Warren, H & L,
and
TransAmeriean.
Although the trustee bases his claims on state law allegations of breach of fiduciary duty, he is arguing that the Donaldsons violated their fiduciary duties to the unsecured creditors by diverting business from Insulfoams and not funding the reorganization plan. Therefore, even though the bankruptcy court converted the bankruptcy to a Chapter 7 case, the trustee basically is seeking to carry out the intent of the reorganization plan. Thus, this case, unlike
Haws, Warren, H & L,
and
TransAmerican,
does not involve a dispute essentially collateral to the bankruptcy case. Rather, this action implicates the integrity of the bankruptcy process, as the Donaldsons’ actions impaired Insulfoams’ ability to make the payments required under the plan. In this regard we point out that it has been held that “misconduct during the bankruptcy proceeding” by the debtor often compels the court to allow the fraud to be redressed.
See In re Emmer Bros. Co.,
Furthermore, it has been held that if there is a sufficient nexus, a bankruptcy court can exercise subject matter jurisdiction over a related state law matter by reopening a closed bankruptcy case.
See In re Burch, 88
B.R. 686, 690 (Bankr.E.D.Pa.1988). Significantly, unlike in
Haws,
In reaching our result on the jurisdictional issues we have not lost sight of the theme which recurs in the reported opinions that the jurisdiction of the bankruptcy courts ■must be confined within appropriate limits and does not extend indefinitely, particularly after the confirmation of a plan and the closing of a case. We are in full accord with that approach and indeed have expressed similar reservations regarding a bankruptcy court’s jurisdiction in other contexts.
See Beard v. Braunstein,
C. The Trustee’s Standing
The Donaldsons also argue that the trustee does not have standing to bring this action. They claim that the conversion to Chapter 7 gave the trustee power only over Insulfoams’ pre-confirmation estate. They support this argument by citing
In re T.S. Note Co. TFC,
We find, moreover, that the trustee is the proper party to bring this action. The Donaldsons admit that the creditors would have standing to bring this claim.

Br. at 22. The trustee, as the appointed representative of the creditors, is empowered by the bankruptcy court to represent their interests. “Property of the bankrupt remains
in custodia legis
in the bankruptcy court during the period ... after the discharge of the trustee ... remaining] dormant, in the estate, until the bankruptcy court again appoints a trustee as enforcing guardian.”
Stein v. United Artists Corp.,
D. Res Judicata
The Donaldsons contend that the
res judicata
effect of the confirmation of the plan bars the trustee’s action. It is true that “a confirmation order is
res judicata
as to all issues decided or which could have been decided at the hearing on confirmation.”
In re Szostek,
Claims for post-confirmation acts are not barred by the
res judicata
effect of the confirmation order. In
Matter of Pavlovich,
E. Marion Donaldson’s Liability
The Donaldsons contend that there is no evidence showing that Marion had a fiduciary duty to Insulfoams and thus to its creditors and therefore we should reverse the bankruptcy court’s finding that she had such a duty as clearly erroneous. The bankruptcy court held that the Donaldsons were judicially estopped from asserting that Marion had terminated her relationship with Insulfoams on April 5, 1990, because they did not disclose the alleged resignation when the court approved the plan of reorganization. Thus, both the court and the creditors relied on the representations in the amended disclosure statement that Dennis and Marion Donaldson were running Insulfoams and would guarantee the payments due under the plan.
Insulfoams’ amended disclosure statement indicated that Marion Donaldson was the “primary bookkeeper and financial organizer of the business.” Furthermore, the statement discussed her salary for 1990 and included her as a guarantor of plan payments. Supp. app. at 101. The bankruptcy court approved the amended disclosure statement after a hearing on April 12, 1990, one week after Marion now claims she resigned from Insulfoams. This resignation was not disclosed at the hearing nor at any time until 1994. The bankruptcy court relied on these statements in the amended disclosure statement in approving it as well as the, reorganization plan.
When a party asserts a position inconsistent with a position taken in a previous proceeding, the doctrine of judicial estoppel is implicated.
Oneida Motor Freight, Inc. v. United Jersey Bank,
Nevertheless, Marion did not reveal her alleged 1990 resignation during the confirmation proceedings. Yet surely she had an obligation to disclose her resignation to the bankruptcy court, if she in fact had resigned, before the court approved the amended disclosure statement inasmuch as she was an officer in Insulfoams from the time it filed its Chapter 11 petition on April 24,1989, at least until the date of her purported resignation on April 5, 1990. Thus, she was an officer and shareholder of Insulfoams when it filed the amended disclosure statement on December 28, 1989, in which the Donaldsons undertook to guarantee the payments under the plan. The revelation in the amended disclosure statement that Marion would guarantee In-sulfoams’ payments is particularly significant because the bankruptcy court rejected the original disclosure statement as it did not include any such guaranty. Accordingly, we find that the district court did not abuse its discretion in binding her to her undertakings in the amended disclosure statement and therefore she is judicially estopped from now asserting that-she resigned before plan confirmation.
See McNemar v. The Disney Store, Inc.,
In any event, the bankruptcy court found not credible Marion’s claim that she had resigned, and thus on this basis as well it treated her as an officer and fiduciary of Insulfoams at the times material to this proceeding. In reaching its conclusion, the bankruptcy court examined the totality of circumstances surrounding the bankruptcy case, the severe doubts as to the authenticity of her resignation letter, the failure to disclose the resignation prior to 1994, her participation in the preparation of the court documents after her alleged resignation, and the credibility of the various witnesses. We cannot conclude that the bankruptcy court’s factual conclusions that she had not resigned were clearly erroneous.
Insulfoams,
F. Other Liability Issues
The Donaldsons do not challenge the bankruptcy court’s holding that they owed a fiduciary duty to the creditors, except for their contention, which we have rejected, that Marion owed them no duty because she severed her relationship with Insulfoams in 1990. Thus, they have no basis to object to the award of compensatory damages which, in any event, was justified. 6
The Donaldsons contend, however, that the judgment for punitive damages was inappropriate. It is clear that under Pennsylvania law, which the bankruptcy court treated as applicable in a determination not challenged here, a decision on whether to award punitive damages and the scope of
*557
those damages is in the discretion of the finder of fact.
Delahanty v. First Pennsylvania Bank,
The bankruptcy court found that the Don-aldsons’ actions constituted outrageous conduct above and beyond the breach of fiduciary duty which justified the compensatory damages.
See Smith v. Renaut,
The court awarded $55,602.38 in punitive damages, which when combined with the compensatory damages exactly equals the amount owed to the unsecured creditors under the plan. So, the bankruptcy court in effect held the Donaldsons to their representations in order to deter and punish their misconduct. We find that the weight of evidence supports such a decision and accordingly we affirm the punitive damages award. 8
The Donaldsons raise one last issue. They contend that their personal guaranty is invalid under .the Pennsylvania Statute of Frauds, Pa. Stat. Ann. tit. 33, § 3 (1967), because they did not sign it. While it is unclear whether they raised this argument in the bankruptcy court, we will assume that they did, but will reject it nevertheless. The Pennsylvania Statute of Frauds provides that a guaranty must be in writing and “signed by the party to be charged therewith, or some other person by him authorized.” Id. The amended disclosure statement was in writing and signed by Kenneth Steidl, the attorney for Insulfoams. See supp. app. at 104. As Insulfoams’ only shareholders and officers, the Donaldsons were involved intimately in its reorganization. In the circumstances, there is sufficient evidence that Steidl was authorized to give the Donaldsons’ guaranty.
III. CONCLUSION
The order of the district court entered April 12, 1996, affirming the opinion of the bankruptcy court will be affirmed.

Stein,
. While it is true that the bankruptcy court did consider some pre-confirmation acts in deciding the damage award, it did so only for purposes of ascertaining the Donaldsons' motive and demonstrating a pattern of activity, not for establishing liability. Further, those acts could not have been considered at the confirmation hearing because they did not ripen into a cause of action until the Donaldsons' later breach of fiduciary duty.
. The claims in question were to revoke the debt- or’s discharge, not state law claims of breach of fiduciary duty as we have here.
. While Dennis does not deny that as an officer of Insulfoams he owed a fiduciary duty to its creditors, he does deny that he understood the amended disclosure statement as including his guaranty of the payments to fund the plan. In these circumstances we have no need to review the bankruptcy court's holding that the Donald-sons owed a fiduciary duty to Insulfoams’ creditors trader Pennsylvania law. Of course, we reject Dennis’s contention that he is not bound by the amended disclosure statement. We also point out that the Donaldsons do not challenge the computation of the compensatory damages.
. Although some of these events did take place prior to the plan’s confirmation, the claims are not barred by res judicata because the breaches ' of fiduciary duty did not occur until well afterward. The pre-confirmation events are looked at only for background, pattern of activity, and for evidence of motive. See n.4, supra.
. We also find that the punitive damages were proportional to the compensatory damages, léss than a 2 to 1 ratio, and that there is therefore no need to discuss a possible conflict between
