MEMORANDUM OPINION & ORDER
This matter is before the Court on defendants Harbert International, Inc. ("HII") and Harbert Corporation's ("Harbert") March 1, 2007, Motion in Limine  to bar plaintiffs' claims on contracts 20A, 07, and 29, and defendants' Memorandum  regarding application of the False Claims Act ("FCA") statute of limitations to bar plaintiffs' claims on contracts 20A, 07, and 29. In their Motion and memorandum, defendants present a number of arguments that all of the government's FCA and common law claims, and a majority of the relator's FCA claims are time-barred under the limitations period prescribed under 31 U.S.C. § 3731 of the FCA. Specifically, defendants contend that: (1) the government's FCA claims on contracts 07 and 29 are time-barred because they were filed more than six years after the date of the alleged violations; (2) a substantial number of the government's contract 29 claims are absolutely barred; (3) all of relator's contract 07 claims and most of relator's contract 29 claims are time-barred; (4) the government's common law claims are time-barred; (5) the government's contract 20A claims are barred because they cannot relate back in light of a recent Second Circuit Court of Appeals ruling; and (6) plaintiffs' conspiracy claims are barred under the FCA limitations period.*fn1 The relator filed an opposition  to the defendants' motion in limine, as well as its own memorandum  on the statute of limitations issue. The relator contends that its claims are timely.
For the forgoing reasons, the Court finds that the first four of the defendants' claims are DENIED AS MOOT, and the remaining two claims are DENIED. Accordingly, defendants' motion  and the arguments made within its Memorandum  are DENIED.
A. Four of Defendants' Arguments are Moot in Light of this Court's Recent Opinions
At the outset, the Court can dispose of a number of arguments urged by the defendants in its March 1, 2007, filings that were ultimately rendered moot as a result of this Court's recent series of Memorandum Opinions and Orders as to Magistrate Judge Facciola's Reports and Recommendations. In their memorandum, defendants made a series of arguments that the plaintiffs' FCA claims were time-barred. Defendants also argued that the government's common law claims are time-barred.
Each of the defendants' arguments that the plaintiffs' FCA claims are time-barred are premised upon the magistrate judge's finding in his March 9, 2006, Report and Recommendation  that plaintiffs' claims as to contracts 07 and 29 "must rest on their own feet." As this Court recently held in its Memorandum Opinion and Order , all of the government's claims relate back under Rule 15(c) to the date the relator's original complaint was filed, and therefore are not subject to a separate limitations period analysis. This holding stands equally for the relator's claims as to contract 07 and 29. Accordingly, defendants' motions to dismiss these claims as time-barred are DENIED AS MOOT.
Defendants' motion that the government's common law claims are time-barred reopens an argument defendants previously asserted in its objections to Magistrate Judge Facciola's March 9, 2006, Report and Recommendation . This Court rejected the defendants' objection, and found that the government's common law claims were not time-barred because the government's complaint related back to the date of the relator's original complaint, and the common law claims were subject to a six-year limitations period. In light of the fact that the Court already resolved this issue, defendants' motion to dismiss the government's common law claims as time-barred is DENIED AS MOOT.
B. Analysis of Defendants' Claim that the Government's Contract 20A Claims are Barred Because they Cannot Relate Back in Light of a Recent Second Circuit Court of Appeals Opinion
In this Court's recent Memorandum Opinion & Order , this Court agreed with a finding in Magistrate Judge Facciola's March 9, 2006, Report and Recommendation  that the government's claims on contract 20A could relate back to the date of the original complaint.*fn2
The defendants contend that this finding has been called into question as a result of a recent opinion by the Second Circuit Court of Appeals, in which the Second Circuit found that "Rule 15(c)(2) [of the Federal Rules of Civil Procedure] does not permit relation back [of the government's Complaint in Intervention] to a relator's qui tam complaint, which is filed under seal." United States v. Baylor Univ. Med. Ctr., 469 F.3d 263, 268 (2d. Cir. 2006). Under this holding, the defendants argue that the claims brought by the government against the defendants are time-barred under the FCA's limitations period.
The Court is not convinced for two reasons. First, though the Second Circuit's opinion is contrary to this Court's recent holding, this Court is not obligated to follow the reasoning espoused by the Second Circuit, as its holding is not mandatory authority on this Court. Second, and more importantly, this very Court has previously acknowledged that relation back under Rule 15(c)(2) "applies to FCA claims." United States ex rel. Ortega v. Columbia Healthcare, Inc., 240 F. Supp. 2d 8, 14 (D.D.C. 2003) (Lamberth, J.). Since this Court's opinion in Ortega, there has been no change in the law governing this Circuit regarding the applicability of relation back under Rule 15(c) to FCA cases. This Court finds that its decision that Rule 15(c) relation back applies was correct in Ortega, and remains correct now. Therefore, defendants' motion is DENIED.
C. Analysis of Defendants' Argument that Plaintiffs' Conspiracy Claims are Barred under the FCA Limitations Period
Defendants also argue that the plaintiffs' conspiracy claims are barred in light of Judge Friedman's rationale in United States ex rel. Fisher v. Network Software Assocs., 180 F. Supp. 2d 192 (D.D.C. 2002) (Friedman, J.). In its Memorandum Opinion & Order , this Court adopted Judge Friedman's rationale in determining when the statute of limitations for an FCA conspiracy claim begins to run. (See Mem.
