Removal, the Forum-Defendant Rule, and a Post-Removal Federal Claim
Priya Raman, a Colorado citizen, sued her former employer, Ridgeline Logistics, Inc., a Colorado corporation with its principal place of business in Denver, and Marcus Webb, a Wyoming citizen and Ridgeline's regional manager, in Denver District Court. She asserts only state-law claims, defamation and wrongful discharge, and seeks $180,000. Raman served Ridgeline on April 2 and Webb on April 14. On May 10, Webb filed a notice of removal to the U.S. District Court for the District of Colorado, asserting diversity jurisdiction; Ridgeline filed a written consent the same day. Raman moved to remand on May 24. While the motion was pending, Raman amended her complaint to add a claim under a federal whistleblower statute. Ridgeline then argued that the federal claim supplied subject-matter jurisdiction and that the state claims could ride along under supplemental jurisdiction. The court must decide whether removal was proper, whether the amendment cures any defect, and what to do with the state claims.
1. Was Webb's removal proper, and must the court remand?
Read the worked answer
No, and yes. Federal courts are courts of limited jurisdiction, and the removing party bears the burden of establishing it.
Complete diversity is absent. Ridgeline is a Colorado corporation with its principal place of business in Denver, so it is a Colorado citizen for jurisdictional purposes. Raman is also a Colorado citizen. Diversity jurisdiction requires complete diversity between all plaintiffs and all defendants, and it does not exist here. Webb's Wyoming citizenship cannot supply it.
The forum-defendant rule is an independent bar. A diversity case may not be removed if any properly joined defendant is a citizen of the forum state. The rule looks at all defendants, not just the one who files the notice. Ridgeline was served and joined, and Raman's claims against her employer are the heart of the case, so there is no colorable fraudulent-joinder argument.
Timing does not save the notice. Webb filed within 30 days of service on him, and Ridgeline consented, but a jurisdictional defect is not cured by procedural regularity. The court must remand, and it may raise the defect on its own motion.
2. Does Raman's post-removal amendment adding a federal claim cure the jurisdictional defect?
Read the worked answer
No. Removal jurisdiction is measured as of the date of removal. The reason is structural: if a plaintiff could validate an improper removal by later amending in a federal claim, the removal statutes would lose their consent-based logic and parties could manipulate the forum at will.
The amendment does not retroactively create jurisdiction. At the moment of removal, the court lacked diversity and the case was not removable. The later federal claim may create federal-question jurisdiction going forward, but it does not convert the earlier removal into a proper one. The correct course is remand under the statute governing procedure after removal; the district court should not retain a case that was improperly removed simply because a new claim appears.
Practical consequence. After remand, Raman may choose to file a new federal action on the whistleblower claim, assuming it satisfies federal jurisdiction and the statute of limitations is preserved. She may also proceed in state court on all claims. Either way, the removal notice itself fails.
3. If the court were to retain the case, how would supplemental jurisdiction apply to the state-law claims, and what practical advice follows?
Read the worked answer
Supplemental jurisdiction would likely reach the state claims. The defamation and wrongful discharge claims arise from the same nucleus of operative facts as the whistleblower claim, so they form part of the same case or controversy. The statutory limits on supplemental jurisdiction in diversity cases - which restrict certain claims by plaintiffs against parties joined under specific rules - do not apply here because Ridgeline and Webb are original defendants, not later-joined parties.
Discretion remains. Even where power exists, the court may decline supplemental jurisdiction if the state claims predominate, if the federal claim is novel or has been dismissed, or if state-law issues are exceptionally complex. Wrongful discharge and defamation are quintessentially state-law questions, which cuts toward declining.
Practical advice. Do not assume retention. The safer strategy is to seek remand promptly, preserve the federal claim in a separate filing if the limitations period is close, and advise the client that the state court can hear all claims together. The removal was defective from day one, and the amendment should not be treated as a cure.
