When does the forum defendant rule bar removal under 28 U.S.C. § 1441?

Under 28 U.S.C. § 1441(b)(2), commonly known as the “forum defendant rule,” removal is barred in diversity cases when any properly joined and served defendant is a citizen of the state in which the action was filed. This rule applies only to civil actions removable solely on the basis of diversity jurisdiction under 28 U.S.C. § 1332(a), not to actions invoking federal question or other specialized jurisdictional statutes.

Rule Text and Purpose

Section 1441(b)(2) provides that:

“A civil action otherwise removable solely on the basis of the jurisdiction under section 1332(a) ... may not be removed if any of the parties in interest properly joined and served as defendants is a citizen of the State in which such action is brought.”[2]

The statutory text serves to prevent a forum state's own citizens, who are presumed not to face local bias, from removing cases to federal court based purely on diversity.[1] Thus, even if complete diversity exists, a forum defendant’s presence—upon proper service—bars removal.

Application and Requirements

To trigger the bar, three elements must be met:

1. Diversity Jurisdiction Only: The case must be removable solely under diversity jurisdiction, not federal question jurisdiction.
2. Properly Joined and Served Defendant: The rule applies only if the forum-state defendant has been properly joined and served at the time of removal. Courts are divided on “snap removals,” where an out-of-state defendant removes before a forum defendant is served (compare Encompass Ins. Co. v. Stone Mansion Rest. Inc., 902 F.3d 147 (3d Cir. 2018) (allowing) with Gentile v. Biogen Idec, Inc., 934 F. Supp. 2d 313 (D. Mass. 2013) (disallowing)).
3. Forum-State Citizenship: The defendant must be a citizen of the state where the case was filed.

If these conditions coexist, removal is procedurally improper and the federal court must remand upon timely motion under 28 U.S.C. § 1447(c).

Practical Example

If a Florida citizen is sued in Florida state court by a New York plaintiff, the home-state defendant (the Floridian) cannot remove to federal court under diversity jurisdiction because of the forum defendant rule. However, if the same defendant is sued in Georgia, removal to federal court would be permissible if complete diversity and the amount-in-controversy requirements are otherwise met.

Policy Rationale

The rule mitigates concerns over local bias—the historical purpose of diversity jurisdiction—by ensuring that defendants sued at home cannot manipulate jurisdiction to obtain a perceived advantage. It also prevents procedural gamesmanship through premature or strategic removals, though “snap removal” controversies continue to generate circuit splits.[1]
