Whether a plaintiff’s post-removal amendment, stipulation, or other action reducing the amount recoverable below the jurisdictional minimum requires remand of a diversity case that was properly removed.
Holding
No. Once diversity jurisdiction properly attaches at removal, later events that reduce the amount recoverable below the jurisdictional minimum do not divest the federal court of jurisdiction.
Reasoning
Federal diversity jurisdiction required a controversy exceeding $3,000 at the relevant time. In a removed case, the plaintiff’s complaint at the time of removal ordinarily controls because the defendant must decide whether to remove before its time to answer expires. If the complaint in good faith places more than the statutory amount in controversy, the defendant has a statutory right to remove.
A federal court must remand if it becomes clear that the controversy never really and substantially involved the jurisdictional amount. But that inquiry differs from determining whether later events have diminished a claim that initially satisfied the amount requirement. A valid defense, an adverse ruling, or later proof showing that the plaintiff will recover less than the threshold does not itself show that jurisdiction was absent at the outset.
The same rule applies when the plaintiff voluntarily reduces the demand after removal. Allowing a plaintiff to defeat jurisdiction by amendment, affidavit, or stipulation after removal would make the defendant’s removal right depend on the plaintiff’s unilateral choice. A plaintiff who wishes to ensure a state forum may instead seek less than the jurisdictional amount from the beginning, even if more is actually due.
Earlier decisions, including Kanouse v. Martin and Kirby v. American Soda Fountain Co., established that jurisdiction acquired through removal is not lost because the plaintiff later reduces or dismisses part of the claim. The Court treated the time-of-removal rule as both settled doctrine and a necessary protection for the statutory removal right.
