"If you like your settlement, you can keep your settlement"
                                                                  - B. Obama

Federal courts have long possessed an inherent authority to vacate judgments obtained through fraud upon the court. See Chambers v. NASCO, Inc., 501 U.S. 32, 44, 111 S.Ct. 2123, 2132 (1991) ("the inherent power [to punish for contempts] also allows a federal court to vacate its own judgment upon proof that a fraud has been perpetrated upon the court"), citing Hazel-Atlas Glass Company v. Hartford Empire Company, 322 U.S. 238, 245, 64 S.Ct. 997, 1001 (1944)
