Most Commonly Tested Civil Procedure Issues

Civil Procedure exams are unusually predictable because the doctrine tracks the life of a lawsuit and because a handful of doctrines generate genuinely close questions. In rough order of frequency: (1) personal jurisdiction; (2) subject matter jurisdiction, including removal and supplemental jurisdiction; (3) Erie; (4) Rule 12 pleading and motion practice; (5) joinder and class actions; (6) summary judgment and Rule 50; (7) claim and issue preclusion. Venue, discovery, and appealability appear more often as one-paragraph side issues than as the centerpiece.

The variation across schools is real and it is driven by two things: your professor's casebook and your professor's scholarship. A professor who writes about class actions will test Rule 23 heavily; a professor who spent three weeks on the Seventh Amendment will test Beacon Theatres and Dairy Queen. Before you build a study plan, count the class sessions devoted to each unit and weight your outline accordingly. The syllabus is a better predictor of the exam than any commercial outline.

Run the same four steps every time: (1) is there a statutory basis (a long-arm statute, or Rule 4(k)(1)(A) borrowing the forum state's reach, or Rule 4(k)(2)); (2) is there general jurisdiction; (3) is there specific jurisdiction; (4) is exercise reasonable. Skipping step one is a common and cheap loss of points, especially in states with enumerated-act long-arm statutes rather than "to the limit of due process" statutes.

For general jurisdiction, the modern test is whether the defendant is "essentially at home" in the forum. Goodyear Dunlop Tires Operations, S.A. v. Brown, 564 U.S. 915 (2011), and Daimler AG v. Bauman, 571 U.S. 117 (2014), limit that to the corporation's place of incorporation and principal place of business absent an exceptional case; BNSF Ry. Co. v. Tyrrell, 581 U.S. 402 (2017), confirms that large in-state operations are not enough. Do not forget tag jurisdiction over individuals under Burnham v. Superior Court, 495 U.S. 604 (1990), or consent-by-registration, which the Court blessed on the facts of Mallory v. Norfolk Southern Railway Co., 600 U.S. 122 (2023).

For specific jurisdiction, quote the two-part frame: purposeful availment directed at the forum (Hanson v. Denckla; Burger King Corp. v. Rudzewicz, 471 U.S. 462 (1985); Walden v. Fiore, 571 U.S. 277 (2014)) and a claim that "arises out of or relates to" those contacts. Ford Motor Co. v. Montana Eighth Judicial District Court, 592 U.S. 351 (2021), is the case professors most want cited right now: "relate to" does not require but-for causation, but Bristol-Myers Squibb Co. v. Superior Court, 582 U.S. 255 (2017), still bars claims by plaintiffs with no forum connection. Stream-of-commerce fact patterns should draw the split between O'Connor's and Brennan's Asahi opinions and its unresolved status after J. McIntyre Machinery, Ltd. v. Nicastro, 564 U.S. 873 (2011). Close with the World-Wide Volkswagen reasonableness factors and, if service or notice is at issue, Mullane v. Central Hanover Bank & Trust Co., 339 U.S. 306 (1950).

For federal question jurisdiction under 28 U.S.C. § 1331, apply the well-pleaded complaint rule from Louisville & Nashville Railroad Co. v. Mottley, 211 U.S. 149 (1908): anticipated defenses and counterclaims do not create jurisdiction. If the claim is state-law but embeds a federal issue, run the four-part Grable/Gunn test — necessarily raised, actually disputed, substantial, and capable of resolution without disturbing the federal-state balance. Gunn v. Minton, 568 U.S. 251 (2013), is the cleaner statement of the test.

For diversity, § 1332 requires complete diversity (Strawbridge v. Curtiss) measured at filing, plus more than $75,000 in controversy. Corporate citizenship is state of incorporation and principal place of business, and Hertz Corp. v. Friend, 559 U.S. 77 (2010), defines the latter as the "nerve center." Unincorporated associations take the citizenship of every member. Aggregation rules and the supplemental-jurisdiction workaround from Exxon Mobil Corp. v. Allapattah Services, Inc., 545 U.S. 546 (2005), are frequent trap doors.

Supplemental jurisdiction is a two-step statute: § 1367(a) common-nucleus test from United Mine Workers v. Gibbs, 383 U.S. 715 (1966), then the § 1367(b) carve-out that applies only in diversity-only cases and only to claims by plaintiffs, then § 1367(c) discretion. On removal, cite § 1441, the 30-day clocks in § 1446(b), the forum-defendant rule in § 1441(b)(2), the one-year outer limit for diversity cases, and remand under § 1447(c). Venue under § 1391 and transfer under §§ 1404 and 1406 are usually worth a short paragraph; if there is a forum-selection clause, Atlantic Marine Construction Co. v. U.S. District Court, 571 U.S. 49 (2013), controls, and if the alternative forum is foreign, use forum non conveniens under Piper Aircraft Co. v. Reyno, 454 U.S. 235 (1981).

Start by asking whether a valid Federal Rule of Civil Procedure or federal statute is on point and in direct collision with state law. If yes, apply Hanna v. Plumer, 380 U.S. 460 (1965): the Rule governs if it is arguably procedural and within the Rules Enabling Act, 28 U.S.C. § 2072, and no Rule has ever been struck down. Shady Grove Orthopedic Associates v. Allstate Insurance Co., 559 U.S. 393 (2010), is the fight over how broadly to read a Rule to avoid the collision — Scalia's plurality reads the Rule on its own terms, Stevens's concurrence asks whether the state rule is bound up with substantive rights.

If no Rule is on point, apply the modified outcome-determination test: would applying federal practice be outcome-determinative at the time of filing in a way that encourages forum shopping or inequitable administration of the laws, and are there countervailing federal interests (Byrd v. Blue Ridge Rural Electric Cooperative, 356 U.S. 525 (1958))? Guaranty Trust Co. v. York, 326 U.S. 99 (1945), supplies the statute-of-limitations answer. Add Klaxon Co. v. Stentor Electric Manufacturing Co., 313 U.S. 487 (1941), for choice of law, and Semtek International Inc. v. Lockheed Martin Corp., 531 U.S. 497 (2001), if the question loops into preclusion.

On pleading, do not just recite "plausibility." Run Iqbal's two steps: strip conclusory allegations of the presumption of truth, then ask whether the remaining well-pleaded facts state a plausible claim, drawing on judicial experience and common sense. Bell Atlantic Corp. v. Twombly, 550 U.S. 544 (2007), and Ashcroft v. Iqbal, 556 U.S. 662 (2009), are mandatory citations. Flag Rule 9(b) for fraud and mistake, and Rule 15(c) relation back — including Krupski v. Costa Crociere S.p.A., 560 U.S. 538 (2010), where the test is what the new defendant knew or should have known, not the plaintiff's diligence.

On motions, know the Rule 12(g) consolidation rule and the 12(h) waiver hierarchy: lack of personal jurisdiction, improper venue, insufficient process, and insufficient service are waived if omitted; failure to state a claim and failure to join a Rule 19 party survive to trial; subject matter jurisdiction is never waived.

For joinder, walk the rules in order: Rule 18 unlimited claim joinder, Rule 20 same-transaction-plus-common-question for parties, Rule 13(a) compulsory counterclaims, Rule 14 impleader limited to derivative liability, Rule 19 necessary-and-indispensable, Rule 24 intervention. Every joinder answer needs a supplemental jurisdiction paragraph. For class actions, run all four Rule 23(a) elements — Wal-Mart Stores, Inc. v. Dukes, 564 U.S. 338 (2011), on commonality and (b)(2) — then the (b) category, with Amchem Products, Inc. v. Windsor, 521 U.S. 591 (1997), on predominance and Comcast Corp. v. Behrend, 569 U.S. 27 (2013), on damages models. Discovery usually turns on Rule 26(b)(1) scope and proportionality, work product under Rule 26(b)(3) and Hickman v. Taylor, 329 U.S. 495 (1947), and Rule 37 sanctions including the ESI safe harbor in Rule 37(e).

Summary judgment questions almost always turn on burdens. Celotex Corp. v. Catrett, 477 U.S. 317 (1986), lets a movant without the burden of proof point to the absence of evidence; Anderson v. Liberty Lobby, Inc., 477 U.S. 242 (1986), imports the substantive evidentiary standard into the genuineness inquiry; Matsushita requires more than metaphysical doubt. Compare Rule 56 to Rule 50 judgment as a matter of law: the legal standard is the same, but Rule 50(b) requires a pre-verdict Rule 50(a) motion, and Rule 59 new trial is a lower bar reviewed for abuse of discretion.

Preclusion is the classic final-question issue because it requires a second lawsuit. For claim preclusion, state the elements — valid final judgment on the merits, same claim under the transactional test, same parties or privies — and cite Taylor v. Sturgell, 553 U.S. 880 (2008), for the narrow categories of nonparty preclusion. For issue preclusion, require that the issue was actually litigated, actually decided, essential to the judgment, and that the party against whom it is used had a full and fair opportunity. Nonmutual offensive use is discretionary under Parklane Hosiery Co. v. Shore, 439 U.S. 322 (1979). If a federal diversity judgment is being given effect, Semtek borrows state preclusion law.

Appealability is worth a paragraph whenever the fact pattern says a party "immediately appeals." The baseline is the final judgment rule, 28 U.S.C. § 1291; the exceptions are § 1292(a)(1) injunctions, § 1292(b) certified questions, Rule 54(b) partial judgments, Rule 23(f) class certification, mandamus, and the collateral order doctrine of Cohen v. Beneficial Industrial Loan Corp., 337 U.S. 541 (1949). Then name the standard of review: de novo for law, clear error for findings of fact under Rule 52(a)(6), abuse of discretion for discovery and new trial rulings.

Read the call of the question first and note who is moving for what. Most Civ Pro fact patterns are organized chronologically, so an answer organized in the order the court would take the issues — PJ, SMJ, removal, venue, Erie, pleading, joinder, discovery, disposition, appeal — will track the grading rubric almost line for line. Use headings. Graders scan.

Spend your words on the contested element, not the conceded ones. If the defendant is incorporated and headquartered in the forum, general jurisdiction is one sentence, and the remaining time goes to the amount in controversy or the § 1367(b) carve-out. Argue both sides on any element where the facts are ambiguous, and say which way you come out; a conclusion with a reason beats a hedge. Finally, ask your professor whether the exam is open-rule-book. If it is, tab Rules 4, 8, 12, 13-24, 26, 56, and the jurisdiction and venue sections of Title 28, and stop memorizing rule numbers you can look up.
