DefendanL-Appellant Wild Oats Market, Inc. (“Wild Oats”) appeals the district court’s order remanding this action to state court. Wild Oats removed this action to the District Court for the Central District of California alleging that, because the parties were completely diverse and the amount in controversy exceeded $75,000, diversity jurisdiction existed under 28 U.S.C. § 1332, and therefore removal was proper under 28 U.S.C. § 1441(a). 1 Plaintiff-Appellee Emma C. Lively (“Lively”) did not object to the removal. However, after the case had been pending in the district court for approximately eight months, the court, acting sua sponte and invoking its authority under 28 U.S.C. § 1447(c), determined that diversity jurisdiction did not exist because Wild Oats, contrary to the removal requirement of 28 U.S.C. § 1441(b), was a citizen of the state of California. Treating this requirement as a jurisdictional limitation on Wild Oats’ right of removal under § 1441(a), the district court remanded Lively’s action to state court.
Although Wild Oats does not dispute that it is a citizen of California and therefore a forum defendant within the meaning of § 1441(b), 2 it argues that its violation of the forum defendant rule was a procedural defect in the removal process, which Lively had to raise within the 30 days following removal as required by § 1447(c). Because Lively did not object within the 30-day period, Wild Oats argues that Lively waived the defect and that the district court lаcked authority to remand the case to state court.
We must decide whether the forum defendant rule contained in § 1441(b) is jurisdictional or procedural, and thus whether a violation of this rule constitutes a jurisdictional or procedural defect. This issue has been addressed by nine of our sister circuits. It is, however, an issue of *936 first impression in this circuit. 3 We join eight of the nine circuits that have decided this issue and hold that the forum defendant rule is procedural, 4 and therefore a violation of this rule is a waivable defect in the removal process that cannot form the basis for a district court’s sua sponte remand order. Because the forum defendant rule is non-jurisdictional, we further hold that 28 U.S.C. § 1447(d) does not bar appellate review of the district court’s remand order, which was based on Wild Oats’ violation of the forum defendant rule.
I. Background
On September 26, 2003, Lively filed a personal injury action against Wild Oats in statе court seeking damages for a slip and fall accident that occurred in one of Wild Oats’ California stores. On January 8, 2004, Wild Oats filed a notice of removal pursuant to 28 U.S.C. § 1441(e), asserting that diversity jurisdiction existed under 28 U.S.C. § 1332 because it was a citizen of Delaware, its state of incorporation, and Colorado, its principal place of business, and that Lively was a citizen of New York. Wild Oats also alleged that the amount in controversy exceeded $75,000. Lively did not object to the removal.
On August 25, 2004, after discovery ensued and after Wild Oats filed a motion for summary judgment, the district court issued an order to show cause why the case should not be remanded to state court. According to the district court, “removal appear[ed] to be improper” because Wild Oats’ principal place of business was California, not Colorado. Wild Oats insisted that removal was proper even if it were a California citizen because diversity jurisdiction still existed, and therefore the district court could only remand the case to state court if Lively so moved within the 30-day time limit imposed by 28 U.S.C. § 1447(c). Because the time limit had expired, Wild Oats argued that the district court could not order a remand.
The district court nonetheless remanded the case to state court for lack of subject matter jurisdiction. As noted, the district court determined that removal was improper because Wild Oats, a California citizen and local defendant, violated the *937 forum defendant rule contained in § 1441(b). The court determined that this violation “constitute[d] a jurisdictional defect” and therefore remand was “timely and proper” pursuant to § 1447(c). Wild Oats timely appealed.
II. Discussion
Jurisdiction & Standard of Revieiv
Lively argues that we lack jurisdiction to address whether the forum defendant rule is jurisdiсtional or procedural because § 1447(d) bars appellate review of the district court’s remand order, which was based on a lack of subject matter jurisdiction pursuant to § 1447(c). We disagree. As explained below, although § 1447(d) limits appellate review of district court remand orders, this does not mean that we must simply turn this case away because the district court asserted that it lacked jurisdiction and assume that the remand wаs authorized by § 1447(c). Rather, we must determine whether the district court correctly applied § 1447(c) by deciding that the forum defendant rule is a jurisdictional limitation that may be invoked
sua sponte
at any time. In so doing, we determine our own jurisdiction.
See Special Invs., Inc. v. Aero Air, Inc.,
In addition to one inapplicable exception, § 1447(d) provides that “[a]n order remanding a case to the State court from which it was removed is not reviewable on appeal or otherwise.” The Supreme Court has cabined this broad language by construing § 1447(d)’s bar on appellate review as applicable only to remand orders issued pursuant to § 1447(c).
See Thermtron Prods., Inc. v. Hermansdorfer,
A motion tо remand the case on the basis of any defect other than lack of subject matter jurisdiction must be made within 30 days after the filing of the notice of removal under section 1446(a). If at any time before final judgment it appears that the district court lacks subject matter jurisdiction, the case shall be remanded.
28 U.S.C. § 1447(c) (2006). Following the Supreme Court’s direction, this court has determined that, taken together, §§ 1447(c) and (d) bar appellate review of a remand order only if the district court had authority to remand under § 1447(c).
Kelton Arms Condo. Owners Ass’n., Inc. v. Homestead Ins. Co.,
Lively is correct that
if
the district court remanded under its § 1447(c) authority, we would lack jurisdiction to review the order.
See United Investors Life Ins. Co. v. Waddell & Reed Inc.,
Therefore, because, as the Third Circuit noted in
Korea Exch. Bank, N.Y. Branch v. Trackwise Sales Corp.,
We review
de novo
a district court’s decision to remand a removed case and its determination that it lacks subject matter jurisdiction.
Neb. ex rel. Dep’t of Soc. Servs. v. Bentson,
*939 Forum Defendant Rule
Separate and apart from the statute conferring diversity jurisdiction, 28 U.S.C. § 1332, § 1441(b) confines removal on the basis of diversity jurisdiction to instances where no defendant is a citizen of the forum state. As explained below, we hold that this additional limitation on diversity-based removal jurisdiction is a procedural, or non-jurisdictional, rule. Our holding is compelled by a close analysis of the legislative history of § 1447(c), 8 the policy rationale of § 1441(b), the prevailing law of our sister circuits, and Supreme Court precedent.
As originally written, § 1447(c) required the district сourt to remand a case to state court “[i]f at any time before final judgment it appears that the case was removed improvidently and without jurisdiction.” 28 U.S.C. § 1447(c) (1948) (emphasis added). Due to the ambiguous nature of the term “improvidently,” Congress amended the subsection in 1988 to provide, in relevant part:
A motion to remand the case on the basis of any defect in removal procedure must be made within 30 days after the filing of the notice of removal under § 1446(a). If at any time before final judgment it appears that the district court lacks subject matter jurisdiction, the ease shall be remanded....
Judicial Improvements and Access to Justice Act of 1988, Pub.L. No. 100-702, § 1016(c)(1) (emphasis added). Although the new clause, “defect in removal procedure,” was an improvement from “improvident,” confusion remained over what removal defects triggered the 30-day time limit.
See
David D. Siegel,
Commentary on 1996 Revision of Section 1447(c),
28 U.S.C.A. § 1447 (West Supp.1988). Removal defects that were not traditionally categorized as procedural, but also did not impact subject matter jurisdiction, occupied a grey area in the law. Until Congress enacted further revisions to § 1447(c) in 1996, some courts placed the forum defendant rule in this grey area.
See Snapper,
As amended in 1996, a remand motion “on the basis of
any defect other than lack of subject matter jurisdiction
must be made within 30 days after the filing of the notice of removal under § 1446(a).” Pub.L. No. 104-219, § 1 (1996) (emphasis addеd). We agree with the Eleventh Circuit’s historical analysis of § 1447(c), which concludes that, by substituting “defect other than lack of subject matter jurisdiction” for “defect in removal procedure,” Congress sought to ensure that even the “more substantive” removal defects, such as § 1441(b) violations, were subject to the 30-day time limit.

The purpose of the forum defendant rule also supports treating it as a non-jurisdictional requirement. Removal based on diversity jurisdiction is intended to protect out-of-statе defendants from possible prejudices in state court.
See Tosco Corp. v. Cmtys. for a Better Env’t.,
Our interpretation of § 1441(b) comports with eight of the nine circuits that have addressed this issue.
See, e.g., Handelsman v. Bedford Vill. Assocs. Ltd. P’ship,
In contrast to the “overwhelming weight of authority ... on the ‘nonjurisdictional’ side of the debate,”
Hurley,
In addition to citing
Hurt,
the district court in this case relied on
WRS Motion Picture and Video Lab. v. Post Modern Edit, Inc.,
The WRS court recognized that, in
Grubbs,
the Supreme Court held that a removal defect similar to a § 1441(b) violation does not defeat jurisdiction.
In
Grubbs,
the Supreme Court held that where a removed case is tried on the merits without objection and the federal court enters judgment, the jurisdictional issue on appeal is not whether removal was proper, but whether the district court would have had jurisdiction over the case had it been originally filed in federal court.
11
Although the district court here was persuaded by this interpretation of
Grubbs,
the WRS court misconstrued
Grubbs’s
holding. Despite noting that the removal in
Grubbs
was improper, the Supreme Court held that the district court retained jurisdiction to enter judgment and the defect “may not be raised for the first time on appeal.”
Grubbs,
In sum, the legislative history of § 1447(c), the policy rationale of § 1441(b), the result reached by the “overwhelming” majority of our sister circuits, and Supreme Court precedent compel our holding.
III. Conclusion
We hold that the forum defendant rule embodied in § 1441(b) is a procedural requirement, and thus a violation of this rule constitutes a waivable non-jurisdictional defect subject to the 30-day time limit imposed by § 1447(c). In this case, because Lively failed to object, the district court exceeded its § 1447(c) authority in ordering a remand. Therefore, we review the district court’s remand order pursuant to § 1447(d), and vacate the order and remand for further proceedings consistent with this opinion.
ORDER VACATED and REMANDED.
Notes
. In its notice of removal, Wild Oats stated that "this action may be removed ... pursuant to the provisions of 28 U.S.C. Section 1441(b).” Because Wild Oats’ removal was based on diversity jurisdiction, we assume that Wild Oats meant to state that removal was proper under § 1441(a), not § 1441(b).
. Section 1441(b) provides:
Any civil action of which the district courts have original jurisdiction founded on a claim or right arising under the Constitution, treaties or laws of the United States shall be removable without regard to the citizenship or residence of the parties. Any other such action shall be removable only if none of the parties in interest properly joined and served as defendants is a citizen of the State in which such action is brought.
28 U.S.C. § 1441(b) (2006).
. Although we have not directly addressed the nature of the forum defendant rule, this issue wаs raised in
Spencer v. United States Dist. Court for the N. Dist. of Cal.,
. Part of the difficulty with this issue may be attributed to semantics. The forum defendant rule does not fit neatly within the traditional meaning of removal procedure — a concept that 28 U.S.C. § 1446 reserves for more programmatic rules, such as filing deadlines and service requirements. Perhaps a more accurate descriptor for the forum defendant rule in § 1441(b) is one which does not detract from its substantive nature, such as "non-jurisdictional.” We acknowledge, however, that our sister circuits often use the term "procedurаl,” and that there exists a conventional dichotomy of jurisdiction and procedure in the context of removal proceedings under § 1441(b). We therefore use both "procedural” and “non-jurisdictional” interchangeably to describe the forum defendant rule.
. The Supreme Court recently reiterated § 1447(c)'s limitation on the scope of § 1447(d).
Kircher v. Putnam Funds Trust,
- U.S. -,
. Lest there be any confusion, our review of the remand order does not conflict with this court's case law that bars review of § 1447(c) remand orders. In
Kunzi,
for example, we refused to review a district court’s remand order because we concluded that it was based on a "jurisdictional determination that
falls within section 1447(c),
and is thus unreviewable."
. Our jurisdiction is premised on 28 U.S.C. § 1291. Although the district court did not enter a final judgment on the merits of Lively's slip and fall claim, its remand order had the force of a final order given that it "put the litigants effectively out of [federal] court."
