You’re staring at an MBE question about a defendant who just got sued in state court and wants to move the case to federal court. Your brain freezes. Was it 30 days to remove? Does diversity matter? What if one defendant is from the forum state? Removal to federal court trips up more bar exam takers than almost any other Civil Procedure topic because it combines multiple jurisdictional rules into a single procedural move.

Let’s break down exactly when and how removal works for the MBE.

What Is Removal Jurisdiction?

Removal is the procedural mechanism that allows a defendant to transfer a civil action from state court to federal court. Think of it as the defendant’s answer to the plaintiff’s forum choice. The plaintiff picked state court, but the defendant wants a federal forum instead.

Here’s the foundational rule: A defendant may remove any civil action filed in state court over which the federal district court would have original jurisdiction. That language—“original jurisdiction”—is critical. It means the case must be one that could have been filed in federal court in the first place.

The statutory authority is 28 U.S.C. § 1441, which you won’t need to recite on the MBE but should recognize when you see removal fact patterns.

The Two Pathways to Removal

Since removal requires original federal jurisdiction, there are only two ways a case becomes removable: federal question jurisdiction or diversity jurisdiction.

Federal Question Cases

If the plaintiff’s complaint asserts a claim arising under federal law—the Constitution, a federal statute, or a treaty—the defendant can remove. The federal question must appear on the face of the well-pleaded complaint. An anticipated federal defense doesn’t count.

Example: Plaintiff sues Defendant in state court alleging violation of the Americans with Disabilities Act. Defendant can remove because the ADA is federal law and the claim arises under it. The case could have been filed in federal court originally, so removal is proper.

Diversity Cases

If the case satisfies complete diversity (no plaintiff shares citizenship with any defendant) and the amount in controversy exceeds $75,000, the defendant can remove—with one major exception.

Here’s the catch that shows up constantly on the MBE: In diversity cases, the action may not be removed if any properly joined defendant is a citizen of the forum state. This is called the forum defendant rule or the in-state defendant bar.

Example: Plaintiff, a citizen of California, sues Defendant A (citizen of New York) and Defendant B (citizen of Oregon) in Oregon state court for $100,000 in damages. Defendant B cannot remove because B is a citizen of Oregon—the forum state. Even though diversity exists and the amount is satisfied, the forum defendant rule blocks removal.

But if that same case were filed in California state court, both defendants could remove. Neither is a California citizen, so the forum defendant rule doesn’t apply.

The 30-Day Removal Clock

Timing is everything with removal. The defendant must file a notice of removal in federal court within 30 days of receiving the initial pleading or summons, whichever comes first.

This deadline is strictly enforced. If you wait 31 days, you’ve waived removal. The MBE loves testing whether a defendant acted timely.

Key detail: The 30-day clock starts separately for each defendant. If Defendant A is served on January 1 and Defendant B is served on January 15, Defendant B has until February 14 to remove (assuming all defendants consent).

Speaking of consent: all defendants who have been served must consent to removal. One defendant can’t unilaterally yank the case to federal court over the objection of co-defendants. If even one served defendant refuses, removal fails.

The One-Year Diversity Removal Limit

Here’s a wrinkle that occasionally appears: In diversity cases (not federal question cases), there’s an additional time limit. A case cannot be removed on the basis of diversity more than one year after commencement of the action, unless the plaintiff acted in bad faith to prevent removal.

Example: Plaintiff sues Defendant in state court. The case initially appears to involve only $50,000. Eleven months later, Plaintiff amends to add a new claim bringing the total above $75,000, and diversity exists. Defendant can still remove because it’s within one year. But if Plaintiff waits until 13 months to amend, removal is barred unless the defendant can show bad faith.

This rule prevents plaintiffs from manipulating the system, but it also means defendants need to stay alert to changes in the case that might create removal jurisdiction.

Procedural Mechanics: How to Remove

The defendant files a notice of removal in the federal district court for the district and division where the state action is pending. You don’t ask the state court for permission. You notify the federal court and simultaneously notify all parties and the state court.

The notice must include:

Once filed, removal is automatic. The state court loses jurisdiction immediately. The case proceeds in federal court unless the plaintiff successfully moves to remand.

Remand: Sending the Case Back

If removal was improper, the plaintiff can move to remand the case back to state court. This is where MBE questions get tricky because the deadline depends on the type of defect.

Subject matter jurisdiction defects: A motion to remand based on lack of subject matter jurisdiction may be raised at any time—even on appeal. If the federal court never had jurisdiction, the case must go back no matter how much time has passed.

Other defects: A motion to remand based on any procedural defect (like failure to meet the 30-day deadline or lack of unanimous consent) must be made within 30 days of the filing of the notice of removal. After that, the defect is waived.

Example: Defendant removes a diversity case, but one defendant is actually a citizen of the forum state. Plaintiff has 30 days to move for remand based on the forum defendant rule. If Plaintiff waits 35 days, that argument is waived. But if the case lacks complete diversity altogether—say, Plaintiff and Defendant are both California citizens—the court can remand at any time because subject matter jurisdiction never existed.

Common MBE Traps with Removal

The Counterclaim Trap

A defendant cannot remove based on a compulsory counterclaim that arises under federal law. Removal jurisdiction is determined by the plaintiff’s complaint, not the defendant’s answer. The well-pleaded complaint rule applies strictly.

Example: Plaintiff sues Defendant in state court for breach of contract. Defendant’s answer includes a counterclaim alleging patent infringement (a federal claim). Defendant cannot remove. The original complaint sounds in state contract law, so there’s no federal question jurisdiction.

The Diversity Destruction Trap

Watch for fact patterns where diversity exists at filing but disappears before removal. Complete diversity must exist both when the case is filed and when removal is attempted.

Example: Plaintiff (California) sues Defendant (New York) in California state court. Before Defendant removes, Plaintiff amends to add a second defendant who is also a California citizen. Removal is now improper because complete diversity is destroyed.

The Fraudulent Joinder Exception

Occasionally, a plaintiff will join a non-diverse defendant solely to defeat removal. If the defendant can show the joinder was fraudulent—meaning there’s no reasonable basis for the plaintiff to recover against that defendant—the court can disregard the non-diverse defendant for removal purposes.

This is a narrow exception. The defendant must show the plaintiff cannot possibly establish a cause of action against the allegedly fraudulent defendant. It’s not enough that the claim is weak; it must be legally impossible.

Removal and Supplemental Jurisdiction

Once a case is properly removed on federal question or diversity grounds, the federal court can exercise supplemental jurisdiction over related state law claims under 28 U.S.C. § 1367, just as if the case had been filed in federal court originally.

Example: Plaintiff sues Defendant in state court alleging both a federal civil rights violation and a state law battery claim arising from the same incident. Defendant removes based on federal question jurisdiction. The federal court has supplemental jurisdiction over the battery claim because it shares a common nucleus of operative fact with the federal claim.

What to Memorize for the MBE

When you see a removal question, run through this checklist:

  1. Could the case have been filed in federal court originally? (Federal question or diversity?)
  2. If diversity, is any defendant a citizen of the forum state? (Forum defendant rule)
  3. Did the defendant file within 30 days of service?
  4. Did all served defendants consent to removal?
  5. If diversity, has more than one year passed since filing?
  6. If plaintiff moves to remand, what’s the basis? (Subject matter jurisdiction = anytime; procedural defect = within 30 days of removal)

The MBE won’t ask you to draft a notice of removal, but it will absolutely test whether removal was proper under specific facts and whether a remand motion should succeed.

Putting It All Together

Removal questions often combine multiple Civil Procedure concepts—citizenship rules, amount in controversy, timing requirements, and subject matter jurisdiction. That’s why they feel overwhelming. You’re not just testing one rule; you’re applying a sequence of rules in order.

If you want all the removal rules (and the 98 other Civil Procedure rules tested on the MBE) organized for efficient memorization, FlashTables breaks down each element in a two-column format designed for active recall. The Civil Procedure table covers removal jurisdiction alongside the related concepts of original jurisdiction, remand, and supplemental jurisdiction—so you see how the pieces connect rather than memorizing them in isolation.

The key to mastering removal is recognizing the pattern: Defendant wants federal court. Does federal court have original jurisdiction? Is there a procedural barrier (forum defendant, timing, consent)? Can the plaintiff get it sent back? Once you internalize that framework, removal questions become straightforward.
