The Court, on its own motion, has reviewed the complaint in the present case to determine whether it has subject matter jurisdiction. Under Federal Rule of Civil Procedure 12(h)(3), this Court is obligated to review its own jurisdiction sua sponte. See Hammes v. AAMCO Transmissions, Inc., 33 F.3d 774, 778 (7th Cir. 1994) ("the court has an independent duty to satisfy itself that it has subject-matter jurisdiction"); see also Ricketts v. Midwest Nat'l Bank, 874 F.2d 1177, 1181 (7th Cir. 1989). In light of Seventh Circuit Court of Appeals opinions, see, e.g., Smith v. American Gen'l Life and Accident Ins. Co., 337 F.3d 888 (7th Cir. 2003); Tylka v. Gerber Prods. Co., 211 F.3d 445 (7th Cir. 2000); America's Best Inns, Inc. v. Best Inns of Abilene, L.P., 980 F.2d 1072 (7th Cir. 1992) (per curiam), this Court has undertaken a more rigorous initial review of complaints to ensure that jurisdiction has been properly pleaded.
Plaintiff asserts various state law claims related to her use of the prescription drug Ortho Evra transdermal contraceptive patch. She alleges that jurisdiction is proper under 28 U.S.C. § 1332. However, she has failed to properly allege the citizenship of the limited liability company, Johnson & Johnson Pharmaceutical Research and Development, L.L.C. See Belleville Catering Co. v. Champaign Mkt. Place, L.L.C., 350 F.3d 691, 692 (7th Cir. 2003) (limited liability companies are citizens of every state of which any member is a citizen). Additionally, Plaintiff's allegation that she "resides" in Muddy, Illinois is insufficient to establish her citizenship. America's Best Inns, 980 F.2d at 1074 ("[i]n federal law citizenship means domicile, not residence"). "[S]ubject matter jurisdiction must be a matter of certainty and not of probabilities," Murphy v. Schering Corporation, 878 F. Supp. 124, 125-26 (N.D. Ill. 1995), and, at this time, the Court is unable to determine whether Plaintiff can establish the diversity of citizenship requirement by more appropriate allegations.*fn1 See Tylka, 211 F.3d at 447 (noting that federal courts are obligated to inquire sua sponte whenever a doubt arises as to the existence of federal jurisdiction). "[W]hile a court must dismiss a case over which it has no jurisdiction when a fatal defect appears, leave to amend defective allegations of subject matter jurisdiction should be freely given." Leaf v. Supreme Court of Wis., 979 F.2d 589, 595 (7th Cir. 1992). Accordingly, pursuant to 28 U.S.C. § 1653, Plaintiff is ORDERED to file an amended complaint on or before April 13, 2006, to cure the deficiencies set forth above. If Plaintiff fails to file an amended complaint in the manner and time prescribed or if, after reviewing it, the Court finds that Plaintiff cannot establish federal subject matter jurisdiction, the Court will dismiss the action for lack of jurisdiction. See Guaranty Nat'l Title Co. v. J.E.G. Assocs., 101 F.3d 57, 59 (7th Cir. 1996) (remanding case because "[l]itigants who call on the resources of a federal court must establish that the tribunal has jurisdiction, and when after multiple opportunities they do not demonstrate that jurisdiction is present, the appropriate response is clear"); see also Belleville Catering, 350 F.3d at 692 ("Once again litigants' insouciance toward the requirements of federal jurisdiction has caused a waste of time and money.").
