ORDER

DAVID L. RUSSELL, District Judge.

This matter comes before the Court on the Motion to Dismiss, filed by Defendant Midwest Mortgage Capital LLC. (Doc. No. 18) Plaintiffs filed a response in opposition to the motion, asserting that the response is intended to be responsive to both Defendant Midwest Mortgage Capital's motion and to a motion filed by Defendants Citimortgage, Inc. and Mortgage Electronic Registration Systems, Inc. (MERS) on December 2, 2014. Plaintiffs, however, failed to file their response within twenty-one days of the filing of December 2, 2014 motion to dismiss, which was granted by the Court on December 29, 2014. As such, the Court limits its consideration of Plaintiff's January 12, 2014 response to the motion to dismiss filed by Defendant Midwest Mortgage, the only remaining defendant.

This case is one of a series of cases filed by Plaintiffs, appearing pro se and seeking to avoid culmination of or reversal of the foreclosure of their residence by Defendant Citimortgage, which filed a foreclosure action in the District Court of Oklahoma County on June 2, 2011, Case No. CJ-2011-3776.1 Citimortgage was assigned the debt by the original lender, Defendant Midwest Mortgage Capital LLC. Defendant Midwest Mortgage Capital LLC asserts in the instant motion that the Rooker-Feldman doctrine precludes Plaintiffs from pursuing this action, that any claim Plaintiffs might have is barred by the compulsory counterclaim rule, and that the claims are barred by the doctrine of res judicata.

Plaintiffs state in the Complaint that the basis of this action is "the unlawful foreclosure and sale of the subject Property of the Plaintiffs." Complaint, ¶ 9. With regard to Defendant Midwest Mortgage Capital LLC, Plaintiffs allege that on May 5, 2011, MERS, as nominee for Midwest Mortgage Capital LLC signed a purported assignment of real estate mortgage. They allege that an affidavit of Joseph Esquivel, Jr., submitted with their brief, establishes that an interest in the loan was sold by Midwest Mortgage Capital LLC to the Fannie Mae REMIC Trust 2010-122 shortly after execution. As a result, MERS could not have assigned Midwest Mortgage Capital LLC's interest to Citimortgage, and that the sale of the indebtedness without transfer of the Mortgage resulted in expiration of the Mortgage. Plaintiffs contend the assignment recorded by Midwest Mortgage Capital LLC was false, that Defendant breached the covenant of good faith and fair dealing, that the assignment was filed for purposes of harassment and violated the Truth in Lending Act, 15 U.S.C. § 1641(f).

As noted, Defendant Midwest Mortgage Capital LLC seeks dismissal in part premised on the Rooker-Feldman doctrine. The Rooker-Feldman doctrine prevents the federal district courts from entertaining actions brought by "state-court losers" challenging "state-court judgments rendered before the district court proceedings commenced." Lance v. Dennis, 546 U.S. 459, 460, 126 S.Ct. 1198, 163 L.Ed.2d 1059 (2006) (quoting Exxon Mobil Corp. v. Saudi Basic Indus. Corp., 544 U.S. 280, 284, 125 S.Ct. 1517, 161 L.Ed.2d 454 (2005)). "The Rooker-Feldman doctrine is jurisdictional in nature; its applicability must be determined before any other affirmative defense. See Long v. Shorebank Development Corp., 182 F.3d 548, 554-55 (7th Cir.1999) ("Because the Rooker-Feldman doctrine is jurisdictional in nature, its applicability must be determined before considering the defendants' arguments regarding the applicability of res judicata."). Rooker-Feldman operates to stop parties seeking to have a state-court judgment declared void on the basis of alleged errors or mistakes. Even if the state-court erred "that [does] not make the judgment void, but merely [leaves] it open to reversal or modification in an appropriate and timely appellate proceeding." Rooker v. Fidelity Trust Co., 263 U.S. 413, 415, 44 S.Ct. 149, 68 L.Ed. 362 (1923). The Rooker-Feldman doctrine has been applied to bar collateral attacks on judgments entered in state-court foreclosure proceedings. Kline v. Deutsche Bank Nat'l Trust Co. (In re Kline), 472 B.R. 98, 105 (10th Cir. BAP 2012)).

With this understanding of Rooker-Feldman as a backdrop, disposing of the present case under the doctrine is straightforward. The operative question is whether the injury alleged by the Plaintiffs resulted from the state-court judgment itself. Plaintiffs fully admit that it is, asserting in their complaint that they are challenging the unlawful foreclosure and sale of their property. So long as the injury complained of in federal court is "inextricably intertwined" with the state-court judgment, the doctrine applies, which is clearly the case herein. Mann v. Boatright, 477 F.3d 1140, 1147 (10th Cir. 2007).

In order to prevail on their allegations, Plaintiffs would be required to establish that the Defendant Midwest Mortgage Capital LLC did not properly assign its interest. However the state court's final judgment includes the finding that Citimortgage "was the holder of the Note at the time the case was filed" and "is entitled to a foreclosure of its mortgage sued upon in this case." The Court could not enter judgment in favor of the Prestons against Midwest Mortgage Capital, Inc., without reviewing and rejecting the judgment entered by the District Court of Oklahoma County. See Exxon Mobil Corp. v. Saudi Basic Indus. Corp., 544 U.S. 280, 284 (2005). Because Plaintiffs' claims against Midwest Mortgage Capital LLC are inextricably intertwined with the state court's conclusions, they are barred by Rooker-Feldman, and the Court cannot exercise jurisdiction over such claims and Defendant's motion to dismiss is hereby GRANTED.

IT IS SO ORDERED.
