Civil Procedure

Rule 2

FRCP: "There is one form of action—the civil action." Plain English: All civil lawsuits follow the same basic procedural rules. There's no longer a distinction between "law" and "equity" cases.

Rule 3

FRCP: "A civil action is commenced by filing a complaint with the court." Plain English: You officially start a lawsuit by filing your complaint with the court clerk—not by serving the defendant.

Rule 4

FRCP: Governs the summons and service of process. Plain English: This rule explains how to properly notify defendants that they've been sued.

Rule 4(c)

FRCP: Service must be made by a person who is at least 18 years old and not a party to the action. The plaintiff is responsible for having the summons and complaint served within the time allowed. Plain English: You can't serve papers yourself if you're the plaintiff. Someone else (18+) must do it, and it's your job to make sure it gets done.

Rule 4(e)

FRCP: An individual may be served by: (1) following state law where the court is located or where service is made; (2) delivering a copy personally; (3) leaving a copy at the individual's dwelling with someone of suitable age and discretion who resides there; or (4) delivering a copy to an authorized agent. Plain English: To serve a person, you can: hand it to them directly, leave it at their home with a responsible adult who lives there, give it to their agent, or follow the state's service rules.

Rule 4(h)

FRCP: A corporation, partnership, or association may be served by: (1) following state law; or (2) delivering a copy to an officer, managing agent, general agent, or any other agent authorized by law to receive service. Plain English: To sue a company, serve papers on someone in charge (officer, manager) or their registered agent—or follow the state's rules.

Rule 4(k)(1)

FRCP: Serving a summons establishes personal jurisdiction over a defendant who is subject to the jurisdiction of a court of general jurisdiction in the state where the district court is located, or who is a party joined under Rules 14 or 19 and served within 100 miles of the courthouse. Plain English: Federal courts generally "borrow" their state's personal jurisdiction rules. There's also a special 100-mile "bulge rule" for joined parties.

Rule 4(m)

FRCP: If a defendant is not served within 90 days after the complaint is filed, the court must dismiss the action without prejudice or order service be made within a specified time. Plain English: You have 90 days to serve the defendant after filing. Miss the deadline and your case may be dismissed (though you can usually refile).

Rule 7(a)

FRCP: Only these pleadings are allowed: a complaint; an answer to a complaint; an answer to a counterclaim; an answer to a crossclaim; a third-party complaint; an answer to a third-party complaint; and a reply to an answer if ordered by the court. Plain English: The rules strictly limit what counts as a "pleading"—basically complaints, answers, and replies. Motions are NOT pleadings.

Rule 7(b)

FRCP: A motion must state with particularity the grounds for seeking the order and the relief sought. Plain English: When you file a motion, you must clearly explain what you want and why you're entitled to it.

Rule 8(a)

FRCP: A pleading that states a claim for relief must contain: (1) a short and plain statement of the grounds for the court's jurisdiction; (2) a short and plain statement of the claim showing the pleader is entitled to relief; and (3) a demand for the relief sought. Plain English: Your complaint needs three things: why this court has jurisdiction, what happened and why you deserve to win, and what you want (money, injunction, etc.).

Rule 8(b)

FRCP: A party must state in short and plain terms its defenses to each claim and admit or deny the allegations. If a party lacks knowledge or information sufficient to form a belief about the truth of an allegation, the party must so state, and this has the effect of a denial. Plain English: When answering a complaint, you must respond to each allegation: admit it, deny it, or say you don't have enough information (which counts as a denial).

Rule 8(c)

FRCP: A party must affirmatively state any avoidance or affirmative defense, including (but not limited to): accord and satisfaction, assumption of risk, contributory negligence, fraud, illegality, laches, res judicata, statute of frauds, statute of limitations, and waiver. Plain English: If you have a special defense (like "the statute of limitations ran out"), you MUST raise it in your answer or you waive it. These defenses don't automatically apply—you have to assert them.

Rule 8(d)

FRCP: Each allegation must be simple, concise, and direct. A party may set out alternative or inconsistent claims or defenses. Plain English: Keep your pleadings straightforward. You CAN argue inconsistent theories (e.g., "There was no contract, but if there was, the other side breached it").

Rule 8(e)

FRCP: Pleadings must be construed so as to do justice. Plain English: Courts should read pleadings generously and focus on substance over technicalities.

Rule 9(b)

FRCP: In alleging fraud or mistake, a party must state with particularity the circumstances constituting fraud or mistake. Malice, intent, knowledge, and other conditions of mind may be alleged generally. Plain English: Fraud claims require specific details (who, what, when, where, how). You can't just say "they defrauded me"—you must explain exactly what happened. Other mental states can be alleged more generally.

Rule 11(a)

FRCP: Every pleading, motion, and other paper must be signed by at least one attorney of record (or by the party if unrepresented). Plain English: Someone must sign every document filed with the court—this signature carries important responsibilities.

Rule 11(b)

FRCP: By signing, filing, or advocating for a pleading, motion, or paper, an attorney or party certifies that to the best of their knowledge: (1) it is not for an improper purpose; (2) legal contentions are warranted by existing law or a nonfrivolous argument for changing the law; (3) factual contentions have evidentiary support; and (4) denials of factual contentions are warranted. Plain English: Your signature is a promise that you're not filing frivolous papers, your legal arguments have a reasonable basis, and your facts are supported by evidence (or will be after investigation).

Rule 11(c)

FRCP: If the court determines that Rule 11(b) has been violated, it may impose appropriate sanctions. A motion for sanctions must be served on the opposing party but not filed for 21 days (safe harbor), giving the offending party time to withdraw the challenged paper. Plain English: Violate Rule 11 and you can be sanctioned. But there's a "safe harbor"—if someone threatens sanctions, you have 21 days to fix or withdraw your filing before they can actually file the motion.

Rule 12(a)

FRCP: A defendant must serve an answer within 21 days after being served with the summons and complaint (60 days if the defendant waived service). Plain English: You generally have 21 days to respond after being served. If you signed a waiver of service, you get 60 days.

Rule 12(b)

FRCP: Every defense to a claim for relief must be asserted in the responsive pleading, but a party may assert the following defenses by motion: (1) lack of subject-matter jurisdiction; (2) lack of personal jurisdiction; (3) improper venue; (4) insufficient process; (5) insufficient service of process; (6) failure to state a claim; (7) failure to join a party under Rule 19. Plain English: The seven defenses you can raise by motion instead of (or before) answering. Know these numbers—especially 12(b)(6) (failure to state a claim).

Rule 12(b)(1)

FRCP: Motion to dismiss for lack of subject-matter jurisdiction. Plain English: "This court doesn't have the authority to hear this type of case." Can be raised at any time.

Rule 12(b)(2)

FRCP: Motion to dismiss for lack of personal jurisdiction. Plain English: "This court doesn't have power over me—I don't have sufficient connections to this forum."

Rule 12(b)(3)

FRCP: Motion to dismiss for improper venue. Plain English: "Even if this court has jurisdiction, this isn't the right location for the case."

Rule 12(b)(4)

FRCP: Motion to dismiss for insufficient process. Plain English: "There's a problem with the summons itself (e.g., missing information)."

Rule 12(b)(5)

FRCP: Motion to dismiss for insufficient service of process. Plain English: "The summons and complaint weren't delivered to me properly."

Rule 12(b)(6)

FRCP: Motion to dismiss for failure to state a claim upon which relief can be granted. Plain English: "Even if everything in the complaint is true, it doesn't add up to a legal claim. The plaintiff loses as a matter of law." The complaint must contain enough facts to state a claim that is "plausible on its face" (Twombly/Iqbal).

Rule 12(b)(7)

FRCP: Motion to dismiss for failure to join a party under Rule 19. Plain English: "There's a necessary party who isn't in this lawsuit, and the case can't proceed fairly without them."

Rule 12(c)

FRCP: After the pleadings are closed—but early enough not to delay trial—a party may move for judgment on the pleadings. Plain English: After everyone has filed their pleadings, you can ask the court to decide the case based solely on what's in those pleadings (similar to a 12(b)(6) motion, but filed later).

Rule 12(d)

FRCP: If matters outside the pleadings are presented on a 12(b)(6) or 12(c) motion and not excluded by the court, the motion must be treated as one for summary judgment under Rule 56. Plain English: If the court considers evidence beyond the complaint on a motion to dismiss, it converts into a summary judgment motion.

Rule 12(e)

FRCP: A party may move for a more definite statement of a pleading that is so vague or ambiguous that the party cannot reasonably prepare a response. Plain English: "The complaint is too confusing to understand—tell them to clarify before I have to answer."

Rule 12(f)

FRCP: The court may strike from a pleading any insufficient defense or any redundant, immaterial, impertinent, or scandalous matter. Plain English: Courts can delete irrelevant, inflammatory, or bogus content from pleadings.

Rule 12(g)

FRCP: A party that makes a motion under Rule 12 must not make another motion under this rule raising a defense or objection that was available but omitted from its earlier motion. Plain English: You generally must consolidate all your Rule 12 motions into one. No filing them piecemeal.

Rule 12(h)(1)

FRCP: A party waives defenses under 12(b)(2)-(5) by: (A) omitting it from a motion under 12(b), (c), or (e); or (B) failing to include it in a responsive pleading or amendment allowed as a matter of course. Plain English: Personal jurisdiction, venue, and service defenses are WAIVED if you don't raise them in your first response (motion or answer). Use them or lose them!

Rule 12(h)(2)

FRCP: Failure to state a claim (12(b)(6)), failure to join under Rule 19 (12(b)(7)), and failure to state a legal defense may be raised in any pleading, by motion under 12(c), or at trial. Plain English: These defenses can be raised later—you don't waive them by not raising them immediately.

Rule 12(h)(3)

FRCP: If the court determines at any time that it lacks subject-matter jurisdiction, the court must dismiss the action. Plain English: Subject-matter jurisdiction can NEVER be waived. It can be raised at any time—even on appeal.

Rule 13(a)

FRCP: A pleading must state as a counterclaim any claim that—at the time of its service—the pleader has against an opposing party if the claim arises out of the same transaction or occurrence that is the subject matter of the opposing party's claim. Plain English: COMPULSORY counterclaim: If your claim against the plaintiff arises from the same events as their claim against you, you MUST raise it now or lose it forever.

Rule 13(b)

FRCP: A pleading may state as a counterclaim any claim against an opposing party that is not compulsory. Plain English: PERMISSIVE counterclaim: Claims against the plaintiff that arise from different events CAN be raised in this lawsuit, but don't have to be.

Rule 13(g)

FRCP: A pleading may state as a crossclaim any claim by one party against a coparty if the claim arises out of the same transaction or occurrence that is the subject matter of the original action or a counterclaim, or if the claim relates to any property that is the subject matter of the original action. Plain English: A crossclaim is a claim against someone on your same side (e.g., co-defendant suing co-defendant). Must arise from the same transaction.

Rule 13(h)

FRCP: Rules 19 and 20 govern the addition of a person as a party to a counterclaim or crossclaim. Plain English: You can bring new parties into the lawsuit through your counterclaim or crossclaim, following the joinder rules.

Rule 14(a)

FRCP: A defending party may, as third-party plaintiff, serve a summons and complaint on a nonparty who is or may be liable to it for all or part of the claim against it (impleader). Plain English: If you're sued and think someone else should pay (or share responsibility), you can bring that person into the lawsuit as a third-party defendant. Example: Defendant brings in their insurance company.

Rule 15(a)

FRCP: A party may amend its pleading once as a matter of course within 21 days after serving it, or within 21 days after service of a responsive pleading or 12(b), (e), or (f) motion, whichever is earlier. Otherwise, a party may amend only with the opposing party's written consent or the court's leave, which should be freely given when justice so requires. Plain English: You get ONE free amendment early in the case. After that, you need permission (which courts usually grant unless there's prejudice or bad faith).

Rule 15(b)

FRCP: When an issue not raised by the pleadings is tried by the parties' express or implied consent, it must be treated as if raised in the pleadings. The court may permit pleadings to be amended during or after trial. Plain English: If both sides litigate an issue without objection, the pleadings are effectively amended to include it—even if no one formally amended them.

Rule 15(c)

FRCP: An amendment relates back to the date of the original pleading when: (1) the law that provides the applicable statute of limitations allows relation back; (2) the amendment asserts a claim or defense that arose out of the same conduct, transaction, or occurrence set out in the original pleading; or (3) the amendment changes the party against whom a claim is asserted if certain conditions are met. Plain English: "Relation back" lets your amendment count as if filed on the original filing date (important for statute of limitations). Works when the new claim arises from the same events, or when adding/changing a party who had notice.

Rule 15(d)

FRCP: On motion and reasonable notice, the court may permit a party to serve a supplemental pleading setting out transactions, occurrences, or events that happened after the date of the pleading to be supplemented. Plain English: You can add new facts about things that happened AFTER your original filing.

Rule 18(a)

FRCP: A party asserting a claim may join, as independent or alternative claims, as many claims as it has against an opposing party. Plain English: Once you're properly in a lawsuit, you can throw in ALL your claims against that opponent—even unrelated ones. No limit on claim joinder.

Rule 19(a)

FRCP: A person must be joined as a party if: (1) complete relief cannot be accorded among existing parties without that person; or (2) that person claims an interest relating to the subject of the action and disposing of the action without them may impair their interest or leave existing parties subject to inconsistent obligations. Plain English: "Necessary" parties: People who must be joined if feasible—either because the court can't give complete relief without them, or their interests would be harmed.

Rule 19(b)

FRCP: If a person who is required to be joined cannot be joined, the court must determine whether, in equity and good conscience, the action should proceed among the existing parties or should be dismissed. Plain English: "Indispensable" parties: If a necessary party can't be joined (e.g., would destroy diversity), the court decides whether to proceed without them or dismiss the entire case.

Rule 20(a)

FRCP: Persons may join in one action as plaintiffs (or be joined as defendants) if: (1) they assert (or there is asserted against them) any right to relief arising out of the same transaction, occurrence, or series of transactions or occurrences; AND (2) any question of law or fact common to all plaintiffs (or defendants) will arise in the action. Plain English: Permissive joinder: Multiple plaintiffs can sue together, or multiple defendants can be sued together, if their claims arise from the same events AND share common legal/factual questions.

Rule 21

FRCP: Misjoinder of parties is not a ground for dismissing an action. On motion or on its own, the court may add or drop a party or sever claims. Plain English: If parties are improperly joined, the court fixes it by adding, dropping, or separating parties—it doesn't throw out the whole case.

Rule 24(a)

FRCP: On timely motion, the court must permit anyone to intervene who: (1) is given an unconditional right to intervene by a federal statute; or (2) claims an interest relating to the property or transaction that is the subject of the action, and disposing of the action may impair that interest, unless existing parties adequately represent that interest. Plain English: Intervention of right: A non-party can force their way into a lawsuit if they have an interest that might be harmed and no one else is adequately representing them.

Rule 24(b)

FRCP: On timely motion, the court may permit anyone to intervene who: (1) is given a conditional right to intervene by federal statute; or (2) has a claim or defense that shares a common question of law or fact with the main action. Plain English: Permissive intervention: The court has discretion to let someone join if their issues overlap with the case. Not guaranteed—judge decides.

Rule 56(a)

FRCP: A party may move for summary judgment, identifying each claim or defense—or part of a claim or defense—on which summary judgment is sought. The court shall grant summary judgment if the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law. Plain English: Summary judgment: "Let's skip the trial—the key facts are undisputed, and I win as a matter of law." Court views evidence in the light most favorable to the non-moving party.

Rule 56(c)

FRCP: A party asserting that a fact cannot be genuinely disputed must support the assertion by citing to particular parts of materials in the record (depositions, documents, affidavits, etc.). Plain English: You must cite actual evidence to support your summary judgment motion—you can't just make assertions. Point to depositions, documents, declarations, etc.

Rule 56(d)

FRCP: If a nonmovant shows by affidavit or declaration that it cannot present facts essential to justify its opposition, the court may defer considering the motion, deny it, or allow time for discovery. Plain English: If you need more discovery before you can oppose summary judgment, tell the court and ask for more time.

Rule 56(e)

FRCP: If a party fails to properly support an assertion of fact or address another party's assertion of fact, the court may give the party an opportunity to properly support or address the fact, consider the fact undisputed, grant summary judgment if appropriate, or issue other appropriate orders. Plain English: If you don't properly respond to the other side's facts with evidence, the court may treat those facts as admitted.

Rule 16

FRCP: The court may order parties and attorneys to appear for pretrial conferences for expediting disposition, establishing early control, discouraging wasteful activities, improving trial quality, and facilitating settlement. The court must issue a scheduling order. Plain English: Pretrial conferences: Judge manages the case through conferences, sets deadlines in a scheduling order, and may push for settlement. These orders control the case timeline.

Rule 38(a)

FRCP: The right of trial by jury as declared by the Seventh Amendment is preserved to the parties inviolate. Plain English: The Constitution guarantees jury trials in civil cases—this rule preserves that right.

Rule 38(b)

FRCP: A party may demand a jury trial by serving a written demand no later than 14 days after the last pleading directed to the issue is served. Plain English: You must demand a jury trial in writing within 14 days of the last pleading. Miss this deadline and you may lose the right.

Rule 38(d)

FRCP: A party waives a jury trial unless its demand is properly served and filed. A proper demand may be withdrawn only if the parties consent. Plain English: Fail to demand a jury = waiver. Once demanded, you can't withdraw without everyone agreeing.

Rule 39(a)

FRCP: When a jury trial has been demanded, the action must be designated on the docket as a jury action and tried by jury unless the parties consent to trial by the court. Plain English: If someone properly demands a jury, you get a jury trial unless both sides agree to a bench trial.

Rule 39(b)

FRCP: Issues on which a jury trial is not properly demanded are tried by the court, but the court may, on motion, order a jury trial on any issue for which a jury might have been demanded. Plain English: If no one demanded a jury, the judge decides—but the court has discretion to order a jury anyway.

Rule 39(c)

FRCP: In an action not triable of right by a jury, the court may try any issue with an advisory jury, or with the parties' consent, try any issue by jury whose verdict has the same effect as if the right had been demanded. Plain English: Advisory jury: In cases without a jury right (like equity cases), the judge can use a jury for advice, though the judge makes the final decision.

Rule 41(a)

FRCP: A plaintiff may dismiss an action without a court order by filing (1) a notice of dismissal before the opposing party serves either an answer or a motion for summary judgment; or (2) a stipulation of dismissal signed by all parties. Unless the notice states otherwise, the dismissal is without prejudice (but a second voluntary dismissal operates as an adjudication on the merits). Plain English: Voluntary dismissal: Plaintiff can dismiss early without court permission. First dismissal is usually "without prejudice" (can refile), but a SECOND voluntary dismissal of the same claim = with prejudice (can't refile).

Rule 41(b)

FRCP: If the plaintiff fails to prosecute or to comply with the rules or a court order, a defendant may move to dismiss the action. Unless the dismissal order states otherwise, a dismissal under this rule operates as an adjudication on the merits. Plain English: Involuntary dismissal: If plaintiff doesn't prosecute the case or violates rules, defendant can get it dismissed—and it's "with prejudice" (final) unless the court says otherwise.

Rule 49(a)

FRCP: The court may require a jury to return only a special verdict in the form of a special written finding on each issue of fact. Plain English: Special verdict: Instead of just "plaintiff wins," the jury answers specific factual questions and the judge applies the law to those answers.

Rule 49(b)

FRCP: The court may submit to the jury forms for a general verdict, together with written questions on one or more issues of fact. Plain English: General verdict with interrogatories: Jury delivers a winner-loser verdict but ALSO answers specific factual questions. Helps the court check that the verdict is consistent.

Rule 50(a)

FRCP: If a party has been fully heard on an issue during a jury trial and the court finds that a reasonable jury would not have a legally sufficient evidentiary basis to find for the party on that issue, the court may grant a motion for judgment as a matter of law (JMOL). Plain English: JMOL (during trial): After the other side presents their case, you can argue that no reasonable jury could rule for them. If the judge agrees, you win without the jury deciding.

Rule 50(b)

FRCP: If the court does not grant a motion for judgment as a matter of law under Rule 50(a), the movant may file a renewed motion no later than 28 days after entry of judgment. Plain English: Renewed JMOL / JNOV (after trial): If you lose the jury verdict, you can renew your JMOL motion within 28 days, asking the judge to overturn the jury's verdict. CRITICAL: You must have made a 50(a) motion first to preserve this right.

Rule 50(c)

FRCP: If the court grants a renewed motion for judgment as a matter of law, it must also conditionally rule on any motion for a new trial. Plain English: If the judge grants JNOV, they must also say what they would do about a new trial request—in case the JNOV gets reversed on appeal.

Rule 51

FRCP: At the close of evidence (or earlier if the court orders), a party may file requests for jury instructions. A party must object to an instruction or failure to give an instruction before the jury retires to preserve the issue for appeal. Plain English: Jury instructions: You must submit proposed instructions and object to bad instructions BEFORE the jury deliberates, or you waive the issue on appeal.

Rule 59(a)

FRCP: The court may, on motion, grant a new trial on all or some of the issues for any reason for which a new trial has heretofore been granted in an action at law in federal court. Plain English: Motion for new trial: If something went wrong (errors, verdict against the weight of evidence, newly discovered evidence, misconduct), you can ask for a do-over.

Rule 59(b)

FRCP: A motion for a new trial must be filed no later than 28 days after entry of judgment. Plain English: You have 28 days after judgment to file a new trial motion.

Rule 59(e)

FRCP: A motion to alter or amend a judgment must be filed no later than 28 days after entry of the judgment. Plain English: Motion to alter/amend: Ask the court to change its judgment within 28 days (for clear error, new evidence, change in law, or to prevent manifest injustice).

Rule 60(b)

FRCP: On motion and just terms, the court may relieve a party from a final judgment for: (1) mistake, inadvertence, surprise, or excusable neglect; (2) newly discovered evidence; (3) fraud, misrepresentation, or misconduct by an opposing party; (4) the judgment is void; (5) the judgment has been satisfied, released, or discharged, or is based on an earlier judgment that has been reversed; or (6) any other reason that justifies relief. Plain English: Relief from judgment: Escape hatches to undo a final judgment for good reasons. (1)-(3) must be filed within 1 year; (4)-(6) within a "reasonable time." Catch-all (6) is used sparingly.

Rule 61

FRCP: Unless justice requires otherwise, no error in admitting or excluding evidence—or any other error by the court or party—is ground for granting a new trial, vacating a judgment, or reversing a judgment unless the error affects a party's substantial rights. Plain English: Harmless error rule: Courts don't overturn judgments for minor mistakes. The error must have actually affected the outcome to matter.

Rule 68

FRCP: At least 14 days before trial, a defending party may serve an offer to allow judgment on specified terms. If the offer is not accepted within 14 days, it is withdrawn. If the offeree rejects the offer and later obtains a judgment that is not more favorable, the offeree must pay the costs incurred after the offer was made. Plain English: Offer of judgment: Defendant offers to settle. If plaintiff rejects and does worse at trial, plaintiff pays defendant's post-offer costs. Creates pressure to settle.

1254

USC idea: Supreme Court review of cases from the courts of appeals occurs mainly by writ of certiorari, and also by certified questions from a court of appeals. Plain English: How a federal court of appeals case can get to the U.S. Supreme Court (usually: SCOTUS chooses to take it).

1291

USC idea: Courts of appeals have jurisdiction over appeals from final decisions of district courts. Plain English: Usually you can only appeal at the end of the case (the “final judgment rule”).

1292(a)

USC idea: Immediate appeals are allowed from certain interlocutory orders, especially orders “granting, continuing, modifying, refusing or dissolving injunctions” (plus some receivership/admiralty orders). Plain English: Some important mid-case orders—especially injunction rulings—can be appealed right away.

1331

USC words (short): District courts have original jurisdiction of civil actions “arising under” federal law. Plain English: Federal-question subject-matter jurisdiction.

1332

USC idea: Diversity jurisdiction statute (citizenship + amount in controversy rules; plus additional detail in other subsections). Plain English: The main statute for getting into federal court based on diverse parties rather than a federal claim.

1332(a)

USC words (short): Diversity jurisdiction when AIC “exceeds $75,000” and the case is between specified sets of diverse parties (e.g., “citizens of different States”). Plain English: The core diversity grant + the $75,000+ requirement.

1367

USC idea: Supplemental jurisdiction statute (with grant, limits in diversity, and discretionary declination). Plain English: When federal court can hear extra state-law claims/parties tied to the main federal (or diversity) case.

1367(a)

USC words (short): Supplemental jurisdiction over claims “so related” they form the same Article III case or controversy, including claims involving joinder/intervention of additional parties. Plain English: If claims share the same core facts, federal court can usually take them together.

1367(b)

USC idea: In diversity-only cases, supplemental jurisdiction is restricted for certain plaintiff-side claims (notably claims by plaintiffs against persons made parties under Rules 14/19/20/24, and certain would-be plaintiffs under Rules 19/24) when it would undermine § 1332 requirements. Plain English: Diversity cases have extra limits—plaintiffs can’t use supplemental jurisdiction to “end-run” complete diversity/amount rules in certain joinder setups.

1367(c)

USC idea: Court may decline supplemental jurisdiction for reasons like novel/complex state-law issues, state claims predominating, all federal claims dismissed, or other exceptional reasons. Plain English: Even if the court can hear the add-on claims, it can choose not to (especially once the federal anchor claim drops out).

1391(b)

USC idea: General venue bases: (1) where any defendant resides (if all defendants reside in the same state), (2) where a substantial part of events/omissions (or property) occurred, or (3) fallback—any district with personal jurisdiction if no other district works. Plain English: The basic “where can I file this federal case?” statute.

1391(c)(1)

USC words (short): A natural person “resides” where the person is domiciled (for venue). Plain English: For individuals, venue “residence” basically tracks domicile.

1391(c)(2)

USC idea: An entity (corp/LLC/etc.) resides (as a defendant) in any district where it is subject to personal jurisdiction for that case; as a plaintiff, only where it has its principal place of business. Plain English: Companies can “reside” in lots of places for venue—often wherever they’re subject to PJ for the suit.

1391(d)

USC idea: In a state with multiple districts, a corporation is deemed to reside in any district where its contacts would be enough for PJ if the district were a separate state; otherwise, where it has the most significant contacts. Plain English: Special venue residency rule for corporations in multi-district states.

1404(a)

USC words (short): For convenience and in the interest of justice, the court may transfer to a district where the action might have been brought (or where all parties consent). Plain English: Proper venue but inconvenient forum → transfer to a better federal district.

1406(a)

USC words (short): When venue is laid in the wrong district/division, the court must dismiss or, in the interest of justice, transfer to a proper one. Plain English: Fixes improper venue—often by transfer instead of dismissal.

1441

USC idea: General removal statute (sets the basic authorization and key limitations, including diversity-based limits like the forum-defendant rule). Plain English: The main rulebook for moving a case from state court to federal court.

1441(a)

USC words (short): A civil action in state court that is within the district courts’ original jurisdiction “may be removed by the defendant(s)” to the federal district embracing the place where the action is pending. Plain English: If the case could have been filed in federal court originally, the defendant can usually remove it to the local federal court.

1441(b)(2)
