consider both whether the Government has viable claims under the applicable law, and, if so, whether the Government’s pleading was sufficient to invoke the MSP.
A. Sufficiency of Complaint
The district court held that, “at a minimum,” a complaint under the MSP statute must identify the Medicare beneficiaries for whose care reimbursement is sought. Because the Complaint here failed to do so, the court held, the MSP counts were subject to dismissal.
Because the Federal Rules embody the concept of liberalized “notice pleading,” a complaint need contain only a statement calculated to “give the defendant fair notice of what the plaintiffs claim is and the grounds upon which it rests.” Conley, 355 U.S. at 47, 78 S.Ct. at 103; see also Caribbean Broad. Sys., Ltd. v. Cable & Wireless PLC, 148 F.3d 1080, 1086 (D.C.Cir.1998) (“[A] plaintiff need not allege all the facts necessary to prove its claim.”). We have observed that the threshold of sufficiency to which a complaint is held at the motion-to-dismiss stage is “exceedingly low.” See In re Southeast Banking Corp., 69 F.3d 1539, 1551 (11th Cir.1995) (“[F]or better or for worse, the Federal Rules of Civil Procedure do not permit district courts to impose upon plaintiffs the burden to plead with the greatest specificity they can.”).
Rule 24 requires merely that an intervenor’s petition “shall state the grounds [for intervention] and shall be accompanied by a pleading setting forth the claim or defense for which intervention is sought.” Fed.R.Civ.P. 24(e). “The determination of whether the proposed intervenor’s complaint states a cause of action is controlled by the general rules on testing a pleading; the factual allegations of the complaint are assumed to be true ... and the pleading is construed liberally in support of the pleader.” Pin v. Texaco, Inc., 793 F.2d 1448, 1450 (5th Cir.1986) (internal quotes and citation omitted); accord County of Santa Fe v. Public Serv. Co. of N.M., 311 F.3d 1031, 1035 (10th Cir.2002).
The Supreme Court has said in the context of a standing determination that “[a]t the pleading stage, general factual allegations of injury resulting from the defendant’s conduct may suffice, for on a motion to dismiss we presume that general allegations embrace those specific facts that are necessary to support the claim.” Nat’l Org. for Women, Inc. v. Scheidler, 510 U.S. 249, 256, 114 S.Ct. 798, 803, 127 L.Ed.2d 99 (1994) (quoting Lujan v. Defenders of Wildlife, 504 U.S. 555, 561, 112 S.Ct. 2130, 2137, 119 L.Ed.2d 351 (1992)). In Swierkiewicz v. Sorema, N.A., 534 U.S. 506, 511, 122 S.Ct. 992, 997, 152 L.Ed.2d 1 (2002), the Court held that in the employment discrimination context, a complaint is not subject to dismissal for failure to state a claim merely because it fails to “plead facts establishing a prima facie case” of discrimination. As the Court emphasized there:
The liberal notice pleading of Rule 8(a) is the starting point of a simplified pleading system.... Rule 8(a) establishes a pleading standard without regard to whether a claim will succeed on the merits. “Indeed, it may appear on the face of the pleadings that a recovery is very remote and unlikely but that is not the test.”
Courts typically allow the pleader an extra modicum of leeway where the information supporting the complainant’s case is under the exclusive control of the defendant. See Peters v. Amoco Oil Co., 57 F.Supp.2d 1268, 1284-85 (M.D.Ala.1999)
