OPINION
In this appeal we decide whether Dallas Sales Company is judicially estopped from pursuing the claims it has raised in the underlying lawsuit against Aрpellees because of its failure to list those claims in the debtor’s schedules it filed in a prior bankruptcy proceeding.
JUDICIAL ESTOPPEL
Dallas Salеs Co. alleges in its first point that Appellees failed to conclusively establish that it is judicially estopped from pursuing its claims.
PERTINENT AUTHORITIES
“Judicial estoрpel protects the integrity of judicial proceedings by precluding a party from asserting a position in a legal proceeding whiсh is inconsistent with a position previously taken by the party.”
Natl. Loan Investors, L.P. v. Taylor,
Under Texas law, the elements for judicial estoppel are: (1) the opponent made a sworn, inconsistent statement in a prior judicial proceeding; (2) the opponent gained some advantage by the prior statement; (3) the statement was not made inadvertently or because of mistake, iraud or duress; and (4) the statement was deliberatе, clear and unequivocal.
Natl. Loan Investors,
Under federal law, a party which has assumed one position in its pleadings may be estopped from assеrting a contrary position in a subsequent proceeding if: (1) “the position of the party to be estopped is clearly inconsistent with its prеvious one;” (2) that party convinced the court in the previous proceeding to accept its position; and (3) that party assertеd the prior position intentionally rather than inadvertently.

In
National Loan Investors,
this Court applied state law in determining that the debtors in that ease were judicially es-topped from claiming the property at issue as their homestead in a foreclosure proceeding because they had nоt identified the property as homestead in the schedules they filed in a prior bankruptcy proceeding.
However, Appellees сontend that federal law should apply here because the prior proceeding was in bankruptcy court. A majority of Texas cоurts seems to agree with Appellees on this issue.
See Zipp Indus., Inc. v. Ranger Ins. Co.,
For two related reasons, we agree with Appelleеs. First, the primary purpose of judicial estoppel is to preserve the integrity of the prior judicial proceeding.
See Coastal Plains,
Second, under the similar doctrine of res judicata, the Supreme Court has long held that federal law governs when determining whether a state court claim is barred by a prior federal judgment.
John G. & Marie Stella Kenedy Meml. Found. v. Dewhurst,
Accordingly, we agree with other Texas courts that the federal law of judicial es-toppel applies in a case in which the prior proceeding was in federal bankruрtcy court. We overrule National Loan Investors to the extent it is inconsistent with this approach. 2
STANDARD OF REVIEW
To prevail on a summary judgment motion, the movant must demonstrate that there are no genuine issues of material fact and that it is entitled to judgment as a matter of law.
Sw. Elec. Power Co. v. Grant,
Judicial estoppel is an affirmative defense.
See Anadarko Petroleum Corp. v. Thompson,
Application
Dallas Sales Co. does not dispute that it listed none of the claims asserted in this lawsuit as assets in its bankruptcy schedules. Its pursuit of these claims in this post-bankruptcy litigation is clearly inconsistent with the position it took in bankruptcy court.
See Coastal Plains,
Dallas Sales Co. does not dispute that the bankruptcy court accepted its positiоn by authorizing the bankruptcy trustee to abandon the assets of Dallas Sales Co.’s bankruptcy estate because those assets were of “no or little value to the estate.”
Cf. Coastal Plains,
Dallas Sales Co. does contend, however, that its failure to disclose these claims in its bankruptcy schedules was inadvertent. To support this argument, Dallas Sales Co. cites the affidavit of its bankruptcy counsel who states that the claims were “inadvertently omitted” because “the principal concern [at the time of the bankruptcy filing] was to obtain post-petition financing.” Nоtwithstanding this tactical explanation however, it is undisputed that Dallas Sales Co. had knowledge of these claims at a time when it could havе amended its schedules to include them because the claims formed the basis of the adversary proceeding it pursued in bankruptcy cоurt. It is also undisputed that Dallas Sales Co. never amended its schedules.
According to the Fifth Circuit, “the debtor’s failure to satisfy its statutory disclosure duty is ‘inadvertent’ only when, in general, the debtor either lacks knowledge of the undisclosed claims
or
has no motive for their concealment.”
Coastal Plains,
Accordingly, we overrule Dallas Sales Co.’s first point.
CONCLUSION
Because Appellees conclusively estаblished that Dallas Sales Co. is judicially estopped from asserting the claims presented in this lawsuit, we need not address the remainder of the grounds presented in the summary judgment motion or the points challenging them.

gram, Inc. v. Doe,
We affirm the judgment.

. The El Paso Court derived the "playing fast and loose” quote from a federal bankruptcy case.
Andrews v. Diamond, Rash, Leslie & Smith,
. It does not appear that the result would have been any different in National Loan Investors had we applied federal law.
