OPINION
Steve Shewmaker (Shewmaker) appeals a grant of summary judgment in favor of Gerald Etter (Etter). The parties present several issues, which we restate as:
I. Whether the trial court erred in allowing Etter to amend his answer to include several affirmative defenses;
whether the trial court erred in finding that Shewmaker lacked standing to bring this personal injury claim against Etter;
whether Shewmaker waived any objection to the trial court's finding that his claim was barred by the doctrines of equitablе estoppel, judicial estoppel, and res judicata; and
whether the trial court erred in finding that Shewmaker's claim was barred by the doctrines of equitable estoppel, judicial estoppel, and res judicata.
We reverse.
In May of 1990, Shewmaker was driving a motorcycle when it left the road and crashed into a metal guard rail erected on Eitter's property. - Shewmaker sustained serious injury. On October 18 of the same year, Shewmaker filed a Chapter 7 bankruptcy pеtition seeking relief from $62,819.47 in medical bills which he had incurred as a result of the collision. The only creditors listed were the doctors and medical institutions which provided goods and services to Shewmaker as a result of his injuries. Shew-maker failed to list his cause of action against Etter upon his schedule of personal property. In February of 1991, Shewmaker received a discharge in bankruptcy from the United States Bankruptey Court. Unknown to Shewmaker or to the bankruptey сourt *926 judge, Shewmaker actually never had any creditors. Because Shewmaker was covered by Medicare, he never had responsibility to pay the health care providers listed as creditors in the bankruptcy petition. The sole remedy of the health-care providers was against Medicare.
In October of 1991, Shewmaker filed a personal injury action against Etter alleging that Etter was negligent in placing the guard rail upon his property. Almost one yеar after the suit was filed, Etter discovered that Shewmaker had received a discharge in bankruptey, but had failed to list the present cause of action on the schedule of assets. Shortly after receiving notice of Shewmaker's bankruptey, Etter moved for summary judgment based upon the bankruptcy discharge, relying upon the affirmative defenses of standing, equitable estoppel, judicial estop-pel, and res judicata.
Before filing his response to Etter's motiоn for summary judgment, Shewmaker, along with the bankruptcy trustee, petitioned the bankruptey court to reopen the bankruptey proceedings. The bankruptcy court granted the motion, specifically finding that Shew-maker never had any creditors and that the discharge had provided him no relief from debt. The court then amended the property schedule to include Shewmaker's claim against Etter, and on April 6, 1998, dismissed the bankruptey petition nune pro tunc as of June 1, 1990, more than one year before the filing of the personal injury action.
After receiving relief in the bankruptcy court, Shewmaker responded to Etter's motion for summary judgment, arguing that the dismissal cured all defects. The trial court granted summary judgment in favor of Et-ter. The court determined that, because Shewmaker had failed to list the chose in action in his original assets schedule, he did not own the action and thus lacked standing to sue. Further, the court found that the action was barred by еquitable estoppel, judicial estoppel, and res judicata.
I. Amendment
Shewmaker contends that the trial court erred in allowing Etter to amend his answer to include affirmative defenses twenty months after filing his original answer. We disagree.
Although the parties engaged in discovery in the year after Shewmaker filed his complaint, it was not until October 7, 1992, that one of Etter's discovery requests revealed the fact that Shewmaker had filed bankruptcy. Two weeks later, Etter moved for summаry judgment alleging the four affirmative defenses. Rather than responding directly to the summary judgment motion, Shewmaker moved to strike the summary judgment motion claiming that Etter had waived these affirmative defenses for failing to assert them in his answer. Subsequently, Etter moved for leave to amend his answer to include them. The trial court granted Etter leave to amend. 1
It is within the trial court's sound discretion to grant a party leave to amend an answer to include an affirmative defense. Indiana Dept. of Public Welfare v. Clark (1985) 1st Dist.Ind.App.,
Here, Shewmaker claims that he was prejudiced by the amendment because it led to a summary judgment against him. Shewmaker does not claim that the delay in asserting the defenses caused him prejudice; rather, he claims that prejudice resulted because the defenses were successful. According to this logic, a defendant should never be allowed to plead affirmative defenses in the first instance because it might cause the *927 plaintiff to lose. We hold that prejudice must result from delay in asserting the defense, not from the likelihood of the success of the defense itself. 2
Shewmaker claims prejudice upon two other grounds. He'argues that if Etter had asserted the affirmative defenses in his original answer, Shewmaker would have been within the one-year time limit in which revocation of a bankruptcy may be had. Alternatively, he argues that at the time of the original answer, the two-year statute of limitations period on the claim had not yet run, and that therefore he could have substituted the bankruptcy trustee as the correct plaintiff. These arguments have been rejected before. Bradley v. Stiller (1992) 3d Dist.Ind.App.,
Shewmaker claims that the trial court's decision was inequitable because it gave Etter a "windfall" in that Etter was relieved of the responsibility to "pay for his torts." Reply Brief of Appellant at 22. Even a plaintiff who has a clearly meritorious claim against the most egregious of wrongdoers may lose his cause of action if he fails to comply with certain procedural requirements, e.g., the statute of limitations. Arguably, this is a windfall to the defendant. However, our State imрoses a duty upon plaintiffs to comply with requirements necessary for an orderly and workable system of justice. Where the plaintiff's chargeable failure to comply with these requirements results in loss of his cause of action, he may not successfully complain.
Shewmaker has not directed us to a case in which the grant of leave to amend has been reversed, and we find no abuse of discretion here. 3
II. Standing
When a debtor files a petition in bankruptey, the debtоr is divested of all of his or her assets, including any potential causes of action. 11 U.S.C. § 541(a) (1986). Etter argues that the bankruptcy dismissal did not return ownership of Shewmaker's claim to him and, therefore, Shewmaker had no standing to sue. Shewmaker argues that the bankruptey court's order did return the cause of action to him and to hold otherwise would violate the Supremacy Clause of the federal Constitution. We agree.
The federal Constitution grants the federal government exclusivе power to promulgate bankruptcy laws. U.S. Const., art. I, § 8. Accordingly, United States Bankruptey Court rulings upon bankruptcy issues are controlling upon state court issues pursuant to the Supremacy Clause.

Renges, Inc. v. PAC Financial Corp. (1987) 2d Dist.Ind.App.,
The bankruptey court dismissed Shewmaker's petition pursuant to 11 U.S.C. § 349 (1985). "The basic purposе of the [dismissal] subsection is to undo the bank-ruptey case, as far as practicable, and to restore all property rights to the position in which they were found at the commencement
*928
of the case." In re Genovese (1988) E.D.Tenn.,
Despite the statutory wording and history, Etter points out that Shewmaker did not receive a dismissal until after he had been discharged in bankruptcy. Etter cites several cases in which bankruptcy courts have held that in such a situation, not all of the effects of the bankruptcy are nullified. For example, some federal courts have held that a debtor whо has been discharged in bank-ruptey must continue to pay ereditors according to the reorganization plan and that a dismissal does not vacate the plan. In re Searles (1987) D.R.I.,
The flaw in Etter's argument is that we are not a federal bankruptcy court. We do not doubt that in some cases the federal courts have refused to dissolve all of the incidents of the bankruptcy. However, that is not what the bankruptcy judge did in this case.
In the bankruptcy judge's order granting Shewmaker's motion to reopen, the judge detailed Shewmaker's accident, his failure to list the claim, the effect the bankruptcy had upon his ability to pursue the claim, and the fact that he actually had no ereditors. The order recited:
"['Thhe 1990 filing creates a blemish on his credit record without affording him any relief from debt.... Etter's various statutory arguments against reopening ignore the desirability, from a bankruptcy perspective, of the result the Debtor is attempting to achiеve. In a perfect economic world, all debtors would reconsider their decisions to discharge their debts, and reopen their bankruptcy cases to dismiss their petitions, so that all parties could go forward as if no petition had ever been filed." Record at 448-444 (emphasis supplied).
In his order dismissing the case, the bankruptcy judge stated that Shewmaker is "authorized to amend Schedule B of his Schedule of Assets to include the Debtor's cause of action agаinst Gerald Etter which pends before the Marion County Superior Court under Cause No. 49D07-9110-CP-1228...." Record at 448. It affirmatively appears from the record that the bankruptcy judge intended "to undo the bankruptcy case" and "to restore all property rights to the position in which they were found at the commencement of the case." In re Ge-movese, supra,
Etter argues that there are other procedures Shewmaker should have followed in order to regain ownership of the cause of action. He argues that Shewmaker should have sought revocation of the bankruptcy, 5 should have sought to have the asset abandoned from the bankruptcy estate, or should have substituted the bankruptcy trustee as the real party in interest. Again, Etter ignores the fact that Indiana may not dictate to the bankruptcy court the procedures that court should have followed in order to return property to Shewmaker. The bankruptcy judge returned the cause of action to Shew-maker according to the provisions set forth *929 in $ 349. We have no authority to second-guess his methods.
Here, the trial court found, "Once Plaintiff Shewmaker's personal injury claim against Defendant Etter became property of the bankruptcy estate, Plaintiff Shew-maker could not pursue the personal injury claim unless it was abandоned from the bankruptey estate." Record at 515. By stating that abandonment was the only method by which the bankruptcy court could return ownership of the claim to Shewmaker, the trial court, in violation of the Supremacy Clause, impermissibly interpreted federal law. The trial court stated, "Plaintiff Shew-maker lacks standing to pursue the personal injury claim against Defendant Etter." Ree-ord at 515. The basis for the trial court's finding of lack of standing was its improper interpretation of federal law. In reviewing a motion for summary judgment, we apply the same standard as the trial court and, thus, no deference is given the trial court's judgment. Inland Steel v. Pequignot (1993) 4th Dist. Ind.App.,
- Etter argues that if the dismissal did cause Shewmaker to regain ownership of the cause of action, ie., to obtain standing, it was too late. That is, Shewmaker did not gain standing until the time of the bankruptcy court's ordеr, a year after the statute of limitations had expired. We disagree.
The bankruptey judge entered the dismissal of the bankruptey petition nune pro tunc. As Shewmaker points out, nunc pro tunc means "now for then." Black's Law Dictionary 964 (5th Ed.1979). In other words, the bankruptey action was dismissed as of June 1, 1990. The complaint was filed on October 31, 1991. Accordingly, Shewmaker had standing when he filed his original complaint. 6
III. Waiver
Etter contends that Shewmaker has waived any objection to the trial court's finding that his claim was barred by equitable estoppel, judicial estoppel, and res judicata. Etter alleges that Shewmaker's motion in opposition to summary judgment and his appellant's brief only addressed the issue of standing. We disagree. 7
In Etter's brief in support of his motion for summary judgment, he makes the plain statement that Shewmaker is barred by equitable estoppel, judicial estoppel, and res judicata from pursuing the claim. Etter cites to Schlosser v. Bank of Western Indiаna (1992) 1st Dist.Ind.App.,
Etter also claims waiver at the appellate level, In determining whether a party has waived an issue upon appeal, we look to whether the brief is so deficient that the reviewing court is required to make a party's argument upon its behalf. Terpstra v. Farmers and Merchant Bank (1985) 3d Dist.Ind.App.,
IV. Equitable Doctrines
Etter argues that even if the dismissal did return ownership of the cause of action to Shewmaker, the claim should be barred by equitable estoppel, judicial estop-pel, and res judicata. We agree that barring a cause of action in state court based upon these equitable doctrines does not violate the Supremacy Clause. The federal courts cannot decide what effect the filing of a state court action in violation of bankruptey procedures has upon state proceedings. Hendrix, supra,
A. Equitable Estoppel
Etter argues that "equitable es-toppel must be utilized to protect the integrity of the bankruptey system." Brief of Ap-pellee at 42. We agree that state courts have some responsibility to protect the processes of the bankruptey system. Schlosser, supra,
However, an essential element of equitable estoppel, ie., reliance, is not present in this case. Miller Jewelry Co. v. Dickson (1942)
It is true that the bankruptcy judge relied upon Shewmaker's asset schedule in granting his bankruptey discharge. Upon learning of the omitted asset, the bankruptcy trustee could have sought to have Shewmaker's bankruptcy discharge revoked and his original "debts" reinstated. 10 Instead, the trustee chose to join Shewmaker's petition to have the bankruptey dismissed. The bankruptcy court knew that Shewmaker had omitted the cause of action upon the original petition, yet forgave the omission by granting a dismissal. Any reliance placed upon the omission by the bankruptcy court was cured. No creditors relied upon the defective property schedule because Shewmaker had none. Had Shew-maker never received a dismissal from the bankruptcy judge, we might be constrained to recite an additional principle. 11
B. Judicial Estoppel
Etter asserts that because Shew-maker did not include his cause of action in
*931
his bankruptey petition, he is judicially es-topped from asserting the claim nоw. Judicial estoppel is not appropriate in this case. Judicial estoppel prevents a party from assuming a position in a legal proceeding inconsistent with one previously asserted. Tobin v. McClellan (1947)
C. Res Judicato
Finally, res judicata is not applicable in this case. Res judicata bars the relitigation of issues which were actually litigated or which could have been litigated in the first action. Sullivan v. American Cas. Co. of Reading, Pa. (1992) Ind.,
The trial court erred in granting summary judgment.
The judgment is reversed and the cause is remanded for further proceedings.
Notes
. The trial court granted Etter's motion for summary judgment on June 30, 1993, before he granted Etter's motion to amend his answer. Then, on July 12, 1993, the trial court entered a nune pro tunc order amending Etter's complaint as of June 29, 1993, the day before entry of the summary judgment order.
. We note that Shewmaker amended his complaint to include two additional theories of reсovery almost seven months after the original was filed. According to Shewmaker's logic, if he had succeeded in his suit against Etter based upon either of these two theories, Etter would be able to show that he had been prejudiced by the amendment. This argument is without merit.
. - Alternatively, Shewmaker alleges that Etter has waived his affirmative defenses by failing to assert them in his original answer. However, because we hold that the trial court correctly granted Etter leave to amend the answer, the affirmative defenses were included in such answer and were not waived.
. U.S. Const., art. VL
. Both parties misunderstand the role of revocation under 11 U.S.C. § 1144. Revocation "is available only where the order of confirmation is obtained through fraud." Matter of Depew, supra,
Revocation of a discharge is a remedy sought by the bankruptcy trustee where the debtor has fraudulently procured relief from the bankruptcy court. It is not a method by which a debtor may seek to nullify the bankruptcy proceedings.
. Again, whether the bankruptcy judge's nunc pro tunc entry would suffice under Indiana law is of no moment.
. Both parties appear to have been deflected in addressing this argument by citing Franklin Bank and Trust Co. v. Mithoefer (1990) Ind.,
. The only analysis in Schlosser regarding these issues is a flat statement that the doctrines of equitable estoppel, judicial estoppel, and res judi-cata could bar the claim.
. The trial court's conclusions of law simply state:
"By virtue of Plaintiff Shewmaker's failure to disclose the personal injury claim against Defendant Etter in the Shewmaker Bankruptcy, Plaintiff Shewmaker is precluded from pursu *930 ing the personal injury claim against Defendant Etter under the doctrine of equitable es-toppel, judicial estoppel and res judicata." Record at 516.
. Where the debtor procures relief from the bankruptcy court through fraud, the bankruptcy trustee may seek to have the discharge revoked according to 11 U.S.C. § 1144. Matter of Depew, supra,
. Equitable estoppel would be inappropriate in this case upon alternative grounds. As stated by the authority upon which Etter relies, an essential element of equitable estoppel is reliance upon the misrepresentations. Pako Corp. v. City-Trust (1989) D.Minn.,
