Federal-question jurisdiction
- Is federal law an element of the claim?
- Is the issue substantial to the federal system, not merely important to the parties?
- Would federal jurisdiction upset the congressionally approved division of labor?
Trigger rule: A federal court has federal-question jurisdiction only when a federal issue appears on the face of the well-pleaded complaint and satisfies the federal cause-of-action or embedded-federal-issue route.
Diversity and alienage jurisdiction
- Identify every party and every citizenship at filing.
- Confirm no plaintiff shares citizenship with any defendant.
- Calculate whether the pleaded amount legally could exceed $75,000.
Trigger rule: Diversity requires complete diversity measured at filing and a good-faith amount in controversy exceeding $75,000.
Supplemental jurisdiction
- Find an original jurisdiction anchor.
- Test common nucleus.
- If diversity is the sole anchor, apply the plaintiff-side statutory exclusions.
- Consider discretionary decline only after power exists.
Trigger rule: Supplemental jurisdiction covers claims within the same Article III case, but diversity-only plaintiff claims listed in section 1367(b) remain restricted.
Removal, remand, and the forum-defendant rule
- Could the case originally have been filed federally?
- Who seeks removal and have all served defendants consented?
- Check forum citizenship, deadlines, and destination.
- Classify the remand objection as procedural or jurisdictional.
Trigger rule: A removable case must satisfy original federal jurisdiction and every applicable removal procedure, including the diversity forum-defendant rule.
General and specific personal jurisdiction
- Find the forum statute.
- Test consent, waiver, domicile, or service.
- Choose general or specific jurisdiction.
- For specific jurisdiction: purposeful contact, relatedness, fairness.
- Check notice and service separately.
Trigger rule: Specific jurisdiction requires the defendant's purposeful forum contact, a claim arising out of or relating to it, and a reasonable exercise of authority.
Service of process, venue, transfer, and forum non conveniens
- Separate notice, service, personal jurisdiction, and venue.
- Identify every statutory venue route.
- Decide whether original venue is proper.
- Choose transfer or dismissal and state the choice-of-law consequence.
Trigger rule: Federal venue focuses on defendants and substantial events; transfer doctrine then addresses convenience, justice, and any valid forum-selection clause.
Erie, federal common law, and conflicts
- Identify the source of federal authority.
- Ask whether federal and state rules directly collide.
- If no collision, perform the modified outcome-determinative analysis.
- State the chosen law and why.
Trigger rule: Under Erie, valid controlling federal law governs procedure; otherwise the federal court applies forum-state substantive law and its conflicts rules.
Complaints, answers, plausibility, and Rule 11
- Identify pleading type and deadline.
- Separate factual allegations from conclusions.
- Check heightened pleading.
- Track waivable defenses.
- For sanctions, identify certification, notice, safe harbor, and permissible target.
Trigger rule: A complaint must plead factual matter supporting a plausible claim, and every filed paper must satisfy Rule 11 after reasonable inquiry.
Amendments and relation back
- Is amendment available as of right?
- If leave is needed, analyze delay, prejudice, bad faith, and futility.
- If limitations expired, select the relation-back route.
- For a new party, test notice and mistake.
Trigger rule: A post-limitations amendment relates back when it shares the original transaction and, for a changed party, timely notice and a qualifying identity mistake exist.
Joinder, impleader, intervention, and interpleader
- Name the device and its elements.
- Test jurisdiction independently, including section 1367(b).
- Determine whether any claim is compulsory.
- For Rule 19, separate needed, feasible, and indispensable inquiries.
Trigger rule: Joinder requires the correct procedural device and an independent jurisdictional basis or valid supplemental jurisdiction for each added claim.
Class actions
- Define the proposed class and representative.
- Apply all four Rule 23(a) prerequisites.
- Choose the exact Rule 23(b) route.
- Address notice, opt-out rights, manageability, and jurisdiction.
Trigger rule: A class may be certified only when Rule 23(a) and one Rule 23(b) category are proved with evidence and the court addresses the applicable notice and opt-out protections.
Scope, privileges, work product, and sanctions
- Identify the discovery device and proper recipient.
- Test relevance, privilege, and proportionality.
- For work product, ask why and when the material was prepared.
- Use a motion to compel and certification when required before sanctions.
- For lost ESI, apply the specialized rule.
Trigger rule: Discovery reaches proportional, relevant, nonprivileged matter, while privilege, work product, and preservation rules require issue-specific protection and remedies.
Summary judgment, JMOL, renewed JMOL, and new trial
- Identify timing and governing motion.
- State who bears production and persuasion.
- Do not weigh credibility on summary judgment or JMOL.
- For renewed JMOL, confirm preservation.
- Separate harmless error from grounds requiring a new trial.
Trigger rule: JMOL requires legally insufficient evidence and a timely pre-verdict motion; renewed JMOL is confined to preserved grounds, while a new trial addresses broader prejudicial error or injustice.
Juries, judgments, appeals, and preclusion
- Classify relief as legal or equitable.
- Find a final judgment or interlocutory-review exception.
- For later litigation, choose claim or issue preclusion.
- Identify the precise transaction or issue and the party to be bound.
Trigger rule: A valid final judgment bars later transactional claims and actually litigated essential issues, subject to the distinct elements and fairness limits of claim and issue preclusion.
Temporary restraining orders and preliminary injunctions
- Decide whether the order sought is a restraining order or a preliminary injunction and whether notice was given.
- Walk the four Winter factors and note which are shown as likely rather than merely possible.
- Check the Rule 65(b) affidavit and attorney certification for any order without notice, and the 14-day limit.
- Confirm security, specificity of terms, and who is bound, then consider whether an interlocutory appeal lies.
Trigger rule: State whether the order is a restraining order or a preliminary injunction, apply the notice rules, run the Winter factors, and finish with security, specificity, and appealability.
Rule 12: responsive-pleading deadlines, pre-answer motions, and waiver of defenses
- Calculate the deadline to respond from service, waiver, or a ruling on a Rule 12 motion.
- List the Rule 12(b) defenses the defendant has and decide which must be raised now to avoid waiver.
- Check whether an earlier Rule 12 motion omitted a defense that was then available.
- Ask whether matters outside the pleadings were presented, which converts the motion to summary judgment.
Trigger rule: Compute the response deadline, identify each available defense, apply the consolidation and waiver rules, and check whether the motion converts to summary judgment.
Counterclaims, crossclaims, joinder of claims, and permissive joinder of parties
- Identify each claim between the parties and ask whether it arises out of the same transaction or occurrence as the opposing party's claim.
- Decide whether the claim is a compulsory counterclaim, a permissive counterclaim, or a crossclaim against a coparty.
- For joinder of parties, test the same-transaction requirement and the common question requirement.
- Ask whether subject-matter jurisdiction supports each added claim, and whether separate trials or consolidation are warranted.
Trigger rule: Classify each claim as compulsory, permissive or crossclaim, apply the same-transaction test, check joinder of parties under Rule 20, and address jurisdiction and separate trials.
Discovery: scope, disclosures, work product, experts, and the discovery devices
- Ask whether the matter is nonprivileged, relevant to a claim or defense, and proportional; admissibility is not the test.
- Identify the device (deposition, interrogatory, request for production, request for admission, examination) and check its numerical and timing limits.
- For documents prepared for the litigation, run the work-product test: substantial need plus no equivalent, with opinion work product protected.
- For experts, decide whether the witness is retained or a trial-preparation-only expert, and check report, timing and communication protections.
Trigger rule: State the Rule 26(b)(1) scope, apply privilege and work product, check the device's limits and deadlines, and finish with protective orders and Rule 37 sanctions.
Dismissals, default, summary judgment, judgment as a matter of law, and relief from judgment
- Identify how the case ended and when it ended relative to the answer or a summary judgment motion.
- For dismissals, decide whether the dismissal is with or without prejudice, and apply the two-dismissal rule.
- For post-judgment attacks, match the motion to its deadline: 28 days for Rule 50(b), 59(b), 59(e), and a year for the first three Rule 60(b) grounds.
- For an offer of judgment, check the 14-day window and what the unaccepted offer shifts.
Trigger rule: Name the route to final judgment, apply the timing and prejudice rules for it, then address any post-judgment motion by its deadline and standard.
Jury trial: the Seventh Amendment, demand and waiver, jury selection, verdicts, and instructions
- Classify each claim as legal or equitable and ask whether a jury right exists on the issue.
- Check that a jury demand was served within 14 days after the last pleading directed to the issue and filed.
- Ask about jury size, unanimity, and peremptory challenges, and test any strike for a race-based reason.
- For instruction error, ask whether the party requested and objected on the record, stating grounds distinctly.
Trigger rule: Classify the claim, apply Beacon Theatres to mixed claims, check the 14-day demand, and then address selection, verdict form, and preservation of instruction error.
Appealability: final decisions, interlocutory orders, Rule 54(b), the collateral order doctrine, and review of findings
- Ask whether the order ends the whole action, and if not whether a Rule 54(b) certification exists.
- Look for a statutory exception: an injunction order under 1292(a)(1), or a 1292(b) certification and permission.
- Test the collateral order doctrine elements for a decision that is separable, important and effectively unreviewable later.
- Compute the 30-day deadline and check whether a tolling post-judgment motion was timely.
Trigger rule: State the final-judgment rule, then check each exception in turn, and finish with the deadline and the standard of review.
Service of process: who may serve, methods for individuals and corporations, waiver, and the 90-day limit (Rule 4)
- Identify the defendant type: individual, corporation, or another kind of entity.
- Match the method to the rule: personal delivery, abode service, an agent, or state law.
- Confirm the server is at least 18 and not a party.
- Count 90 days from filing and look for good cause or a foreign-service exception.
- Check whether the defendant waived service, and calculate the new answer deadline.
Trigger rule: Identify the defendant, apply the correct method under Rule 4(e) or 4(h), check the 90-day limit and any waiver, and state the consequence.
Removal, remand, venue, and transfer of civil cases in federal court
- Ask whether the federal court would have had original jurisdiction over the state action.
- For a diversity case, apply the forum-defendant rule.
- Count the 30 days from service on each defendant, and check the one-year limit if the case became removable later.
- Confirm that all properly joined and served defendants joined or consented.
- For venue, apply the venue statute and then distinguish dismissal or transfer for wrong venue from transfer for convenience.
Trigger rule: State the basis for federal jurisdiction, then apply the removal restrictions, timing rules, and consent requirements, and finish with the venue or transfer analysis.
Nonparty subpoenas, corporate depositions, document requests, and lost electronic information (Rules 30(b)(6), 34, 37(e), and 45)
- Decide whether the target is a party, which calls for Rule 34 or a notice, or a nonparty, which calls for a Rule 45 subpoena.
- Check the server, the fee tender, and the 100-mile place-of-compliance limits.
- For an organization, look for a Rule 30(b)(6) description and the duty to prepare a designee.
- Calculate the response and objection deadlines.
- For lost electronic information, ask about reasonable steps, prejudice, and intent to deprive before choosing a sanction.
Trigger rule: Identify whether the person is a party or nonparty, choose the correct discovery device, and apply the timing, geographic, and sanction rules.
Plausible pleading and summary judgment: the Twombly, Iqbal, Celotex, and Anderson standards
- On a motion to dismiss, strip out conclusions and labels, then ask whether the remaining facts plausibly show liability.
- Ask whether the alleged facts are just as consistent with lawful conduct.
- On summary judgment, identify who bears the burden of proof at trial on the disputed element.
- Ask whether a reasonable jury could find for the nonmovant on the record evidence.
- Look for undisputed objective evidence that contradicts a party's account.
Trigger rule: Explain the plausibility standard and apply it to the pleaded facts, or state the summary judgment standard, allocate the burden, and ask whether a reasonable jury could find for the nonmovant.
