RONALD L. BUCKWALTER, S.J.
Currently pending before the Court is a Motion for Remand by Plaintiffs Michael and Angelique McGuire. For the following reasons, the Motion is granted.
I. FACTUAL BACKGROUND
On March 1, 2013, Plaintiffs Michael and Angelique McGuire commenced this action, via issuance of a Writ of Summons with the Philadelphia Court of Common Pleas, against Defendants Safeware, Inc. (“Safeware”), Scott Technologies, Inc. (“Scott”), and Tyco International, Inc. (“Tyco”) (collectively “Defendants”). (Pls.’ Mot. Remand, Ex. A.) Thereafter, on June 18, 2013, Plaintiffs filed their Complaint alleging claims for negligence, products liability, breach of warranty, failure to warn, and loss of consortium against all Defendants. (Id., Ex. B.) The claims arose out of the alleged malfunction of a “Scott AV-2000" respiratory protection mask that was being used in the course of Plainiff Michael McGuire’s duties as a firefighter. (Compl. ¶¶ 13–14.) Service was effected on Defendant Safeware on June 19, 2013, on Defendant Tyco on June 21, 2013, and on Defendant Scott on June 27, 2013. (Pl.’s Mot. Remand, Exs. C & D.) Subsequently, on July 2, 2013, Defendant Safeware unilaterally filed a Notice of Removal to federal court.
On July 26, 2013, Plaintiffs filed a Motion to Remand this case back to state court. Defendant Safeware responded on August 9, 2013, Scott filed a Joinder in Safeware’s Response on the same day, and Plaintiffs filed a Reply Brief on August 16, 2013. The Court now turns to a discussion of the Motion’s merits.
II. STANDARD OF REVIEW
Under 28 U.S.C. § 1441(a), a defendant may remove a civil action filed in a state court if the federal court would have had original jurisdiction over the action. 28 U.S.C. § 1441(a). A defendant seeking removal of an action must file a petition for removal with the district court within thirty days of plaintiff’s service of the complaint upon defendant. See 28 U.S.C. § 1446(b). “The defendant bears the burden of establishing removal jurisdiction and compliance with all pertinent procedural requirements.” Winnick v. Pratt, No. Civ.A.03-1612, 2003 WL 21204467, at *2 (E.D. Pa. May 20, 2003) (citing Boyer v. Snap-On Tools Corp., 913 F.2d 108, 111 (3d Cir. 1990)); see also Palmer v. Univ. of Med. and Dentistry of N.J., 605 F.Supp.2d 624, 627 (D.N.J. 2009) (“A party opposing remand must show that removal was proper.”).
Once an action is removed, a plaintiff may challenge removal by moving to remand the case back to state court. Cook v. Soft Sheen Carson, Inc., No. Civ.A.08-1542, 2008 WL 4606305, at *1 (D.N.J. Oct. 15, 2008) (citing 28 U.S.C. § 1447(c)). Remand to the state court is appropriate for “(1) lack of district court subject matter jurisdiction or (2) a defect in the removal process.” PAS v. Travelers Ins. Co., 7 F.3d 329, 352 (3d Cir. 1993). Remand is mandatory and can occur at any time during the litigation if the court determines that it lacks federal subject matter jurisdiction. Kimmel v. DeGasperi, No. Civ.A.00-143, 2000 WL 420639, at *1 (E.D. Pa. Apr. 7, 2000) (citing 28 U.S.C. § 1447(c)). A motion to remand the case on the basis of any defect in the removal procedure, however, must be submitted within thirty days after filing of the notice of removal under section 1446(a). 28 U.S.C. § 1447(c); N. Penn Water Auth. v. Bae Sys. Aerospace Elec., Inc., No. Civ.A.04-5030, 2005 WL 1279091, at *5 (E.D. Pa. May 25, 2005). When faced with a motion to remand, “it is always the removing party’s burden to prove the propriety of removal, and any doubts about the existence of federal jurisdiction must be resolved in favor of remand.” Lumbermans Mut. Cas. Co. v. Fishman, No. Civ.A.99-929, 1999 WL 744016, at *1 (E.D. Pa. Sep. 22, 1999) (citing Batoff v. State Farm Ins. Co., 977 F.2d 848, 851 (3d Cir. 1992)); see also Boyer, 913 F.2d at 111 (The removal statutes “are to be strictly construed against removal and all doubts should be resolved in favor of remand.”) (quoting Steel Valley Auth. v. Union Switch & Signal Div., 809 F.2d 1006, 1010 (3d Cir. 1987)).
Plaintiffs’ current Motion does not contest this Court’s subject-matter jurisdiction over the case, but rather seeks remand based on a purely procedural defect. Specifically, Plaintiffs argue that the removing Defendant, Safeware, has failed to comply with the “unanimity rule” because Defendants Scott and Tyco neither joined in the notice of removal nor consented to the removal.
The right to remove a case from state to federal court is vested exclusively in “the defendant or defendants.” 28 U.S.C. § 1441(a). Section 1446, which governs removal, “has been construed to require that when there is more than one defendant, all must join in the removal petition.” Lewis v. Rego Co., 757 F.2d 66, 68 (3d Cir. 1985); Granovsky v. Pfizer, Inc., 631 F.Supp.2d 554, 559 (D.N.J. 2009). The requirement that all defendants agree to the removal is known as the “unanimity rule.” Balazik v. Cnty. of Dauphin, 44 F.3d 209, 213 n.4 (3d Cir. 1995). Unanimity may be expressed by defendants either jointly filing the notice of removal or consenting to the removal by separate filing. Moore v. City of Phila., No. Civ.A.12-3823, 2012 WL 3731818, at *3 (E.D. Pa. Aug. 29, 2012); Weinrach v. White Metal Rolling and Stamping Corp., No. Civ.A.98-3293, 1999 WL 46627, at *1 (E.D. Pa. Jan. 6, 1999). “[T]he failure of all defendants to remove creates a ‘defect in removal procedure’ within the meaning of § 1447(c), but is not deemed to be jurisdictional.” Balazik, 44 F.3d at 213; see also McGlinchey v. Hartford Accident and Indem. Co., 866 F.2d 651, 653 (3d Cir. 1989)). The Third Circuit has enumerated only three exceptions to the rule: (1) where the non-joining defendant is a nominal party; (2) where a defendant has been fraudulently joined; or (3) where the non-joining defendant was not served at the time the notice of removal was filed. Balazik, 44 F.3d at 213 n.4.
In the case at bar, Defendant Safeware unilaterally filed a Notice of Removal on July 2, 2013. Although it was timely filed within thirty days after Safeware had been served, the Notice was not joined by Defendants Scott or Tyco (the “non-removing Defendants”) and did not include explicit consent forms signed by them. Safeware does not contend that the non-removing Defendants were nominal parties or were fraudulently joined. Nor is there any question that the non-removing Defendants were served with the Complaint prior to the filing of the removal petition. Simple application of the rule of unanimity thus renders the removal procedurally defective, thereby requiring remand to state court.
Defendant Safeware attempts to rebut this conclusion by arguing that Scott’s consent (on behalf of both Scott and Tyco) is implicit from its litigation in federal court. Specifically, on July 5, 2013, counsel for Scott sought to obtain Safeware’s consent to its intended removal of this action. Counsel for Safeware then advised that Safeware had already removed the case three days earlier. (Def. Safeware’s Opp’n Mot. Remand, Ex. H.) Thereafter, on July 10, 2013, Scott answered Plaintiffs’ Complaint in the United States District Court for the Eastern District of Pennsylvania, (id., Ex. I), and, the same, day, filed its Disclosure Statements with the Court. (Id., Ex. J.) On July 26, 2013, Scott then responded to Safeware’s cross-claims and asserted its own cross-claim. (Id., Ex. K.) Removing Defendant Safeware now argues that, by both its communications to counsel for Safeware and its litigation of the matter in this Court, Scott expressly consented to the removal.
The Court finds this argument meritless. As noted above, “[i]n order for removal to be proper, all defendants must unanimously join or consent to the removal through a timely-filed, express written indication of consent.” Lewis v. Consol. Freightways Corp. of Del., No. Civ.A.04-6102, 2005 WL 503317, at *2 (E.D. Pa. Feb. 28, 2005). Under the “timely-filed” aspect of the unanimity rule, all defendants must act to confer consent within the thirty-day period set forth in 28 U.S.C. § 1446(b) and courts are without authority to expand this time period. Alves v. Eagle Crane Serv., Inc., No. Civ.A.05-6699, 2006 WL 1030244, at *2–3 (E.D. Pa. Apr. 19, 2006). The parameters of the “express written indication” requirement are somewhat hazier. “While courts generally do not require all defendants to sign the removal petition itself, most courts have required some form of unambiguous written evidence of consent to the court in timely fashion.” Michaels v. N.J., No. Civ.A.96-3557, 1996 WL 787613, at *5 (D.N.J. Nov. 8, 1996) (emphasis in original). In other words, there must be some “written indication from each defendant, or some person or entity purporting to formally act on its behalf in this respect and to have authority to do so, that it has actually ...
