Rule reference · all stages
Rules 4, 8, 11 and 12 are the ones the course has reached. Discovery, summary judgment and post-trial entries run ahead of the syllabus.
Casebook: Hazard, Fletcher, Bundy & Bradt, Pleading and Procedure (12th ed.). The syllabus skips Pennoyer and Harris v. Balk and begins at International Shoe, p. 58. Outline draft due 10.5.26; midterm 10.7.26.
Each entry gives the governing text, a working rule, how to navigate it, and any Massachusetts difference. A case appears when it teaches an interpretive point; for mechanical provisions the rule text is the authority, and no unrelated landmark is substituted for it.
A federal civil action begins by filing a complaint. Distinguish filing, service, entry of an order, and receipt of notice: different deadlines use different triggers. Rule 6 generally excludes the triggering day, counts intervening days, and moves a last day falling on a weekend or legal holiday; some deadlines cannot be enlarged. Rule 5 ordinarily governs later papers, while Rule 4 governs original process. Filing alone does not answer every substantive limitations question.
How to navigate it
Build an event ledger before calculating. Identify the operative rule and any scheduling order. Hanna illustrates why the source of a procedural requirement matters.
Massachusetts comparison
Massachusetts Rule 6 has a different short-period computation convention; do not copy federal arithmetic.
A federal claim ordinarily must appear in the plaintiff's well-pleaded complaint; an anticipated federal defense does not supply §1331 jurisdiction. A state claim containing a federal issue requires the narrower embedded-question analysis. Separately ask whether the claimant has a concrete injury, causation, and redressability, and whether a live controversy exists. Jurisdiction is distinct from proving the claim.
How to navigate it
Underline what creates the plaintiff's right to relief. Mottley rejected jurisdiction based on an anticipated federal defense; Gunn explains why a federal issue within a state claim need not qualify.
Massachusetts comparison
Massachusetts state courts are not Article III courts; federal standing formulations should not be silently substituted for Massachusetts standing law.
Ordinary diversity requires complete diversity between opposing plaintiffs and defendants and more than $75,000, excluding interest and costs. An individual's citizenship ordinarily follows domicile, not a mailing address. A corporation has incorporation and principal-place-of-business citizenship; Hertz identifies the latter as the actual nerve center. An LLC generally takes each member's citizenship, traced through entity members.
How to navigate it
Make a citizenship table for the relevant time. Separate disputed damages valuation from the legal availability of those damages. Class Action Fairness Act jurisdiction has a different framework; see CP-24.
Massachusetts comparison
Massachusetts state subject matter jurisdiction does not require diversity and depends on the court's statutory competence, not this federal threshold.
Start with a claim within original jurisdiction; ask whether the added claim forms part of the same Article III case or controversy. Then apply §1367(b)'s restrictions in diversity-only cases and §1367(c)'s grounds for declining jurisdiction. A joinder rule is not a jurisdictional grant.
How to navigate it
Label who asserts each claim against whom. Gibbs supplies the common-nucleus foundation; Owen illustrates the danger of assuming that a plaintiff can sue a nondiverse third-party defendant merely because that party is already present. Both precede §1367, whose text now governs. A court's dismissal of all federal claims differs from a plaintiff's amendment deleting them; see CP-05.
Practise it
A3 / B1 / C3 — Test the related claims and plaintiff-side statutory exclusions.
Removal, remand, and changing jurisdictional facts
A. Choosing and entering the court
28 U.S.C. §§1441, 1446–1447
Working rule
Ordinary removal is a defendant's statutory route from state court to the federal district embracing that court. Check original jurisdiction, the diversity forum-defendant restriction, properly joined and served defendants' consent, and the applicable 30-day window. Later ascertainable removability and the one-year diversity limitation have exceptions. Procedural remand objections ordinarily have a 30-day deadline; lack of subject matter jurisdiction requires remand if identified before final judgment.
How to navigate it
Royal Canin (2025) requires remand when an operative amendment removes the federal basis and only supplemental state claims remain. Hain Celestial (2026) rejects treating an erroneous dismissal of a properly joined nondiverse defendant as a cure; Rule 21 was not an escape in its circumstances. Identify an independent remaining jurisdictional basis before applying either proposition.
Identify a statutory basis, then a constitutional basis. For corporations, general jurisdiction ordinarily exists where they are at home; specific jurisdiction concerns the defendant's purposeful forum contacts and a claim arising out of or relating to those contacts, with fairness considered. Consent and other traditional bases require separate analysis.
How to navigate it
Separate the defendant's conduct from the plaintiff's travel. Ford rejects a strict causal-only reading of relatedness but does not make any forum sale sufficient for every claim. Registration is not automatically universal consent; the statute and Mallory's limits matter.
Massachusetts comparison
In Massachusetts, SCVNGR requires an independent long-arm inquiry before constitutional analysis.
General federal venue focuses on qualifying defendant residence or a substantial part of the events/property, with a fallback only when the ordinary options fail. Proper venue can still be inconvenient. Section 1404 ordinarily transfers an action from a proper federal venue; §1406 addresses wrong venue. Forum non conveniens addresses an appropriate alternative outside the federal transfer system.
How to navigate it
A contract selecting a forum does not itself make statutory venue improper. Atlantic Marine explains enforcement of a valid applicable clause and the altered transfer analysis. c. 223, and court-specific provisions; §1391 does not govern a state filing.
Massachusetts comparison
Massachusetts state venue uses its own statutes, including G.L.
On state-law claims in federal court, identify the precise disputed issue. If a valid federal rule directly governs it, apply the rule under Hanna. If not, conduct the applicable Erie analysis, including relevant state substantive interests, forum shopping, inequitable administration, and federal interests. The labels “substantive” and “procedural” begin the inquiry; they do not resolve it.
How to navigate it
Ask separately about the claim's elements, a service method, a limitations rule, and the allocation of judge/jury functions.
Massachusetts comparison
State law governing liability does not bring all Massachusetts civil rules into federal court.
Hanna itself arose from competing federal and Massachusetts service requirements.
Plead jurisdiction, a short and plain statement showing entitlement to relief, and the relief sought. Number paragraphs; separate claims where clarity requires. Alternative and inconsistent theories are permitted. Legal labels unsupported by factual allegations do not supply plausibility; the complaint need not establish the evidence necessary to win.
How to navigate it
For each proposed claim, identify the factual allegations supporting each required component. Twombly found parallel conduct insufficient to plausibly allege agreement in context; Iqbal separates conclusions from well-pleaded facts.
Massachusetts comparison
Massachusetts adopted a plausibility formulation in Iannacchino; it is state precedent, not automatic incorporation of every later federal pleading decision.
Special pleading, capacity, and the right claimant
B. Pleadings, notice, and early decisions
Rules 9 and 17
Working rule
Rule 9 generally does not require an allegation of capacity, except to establish jurisdiction; capacity challenges require a specific denial. Fraud or mistake requires particularity, while mental states may be alleged generally subject to pleading sufficiency. Special damages must be specifically stated. Rule 17 separately addresses the real party in interest, capacity, and protection of minors or incompetent persons.
How to navigate it
An injured minor's claim, a parent's individual claim, and an estate claim are not interchangeable. Identify who owns the claim and who can litigate it. Before dismissing for failure to prosecute in the real party's name, consider Rule 17(a)(3)'s cure mechanism.
Massachusetts comparison
Massachusetts has corresponding Rules 9 and 17; do not confuse either inquiry with subject matter jurisdiction.
Signing and presenting a paper certifies, after reasonable inquiry, a proper purpose, legally supportable contentions, and evidentiary support or a specifically identified expectation of support after investigation/discovery. Good intentions do not excuse an objectively inadequate inquiry. A party sanctions motion is separate and ordinarily served 21 days before filing to permit correction; court-initiated sanctions follow a different route. Rule 11 does not govern discovery papers covered by Rules 26–37.
How to navigate it
Distinguish a supportable inference from a fact the lawyer has invented. Business Guides addresses reasonable inquiry under an earlier rule version; current sanctions procedures must come from today's text.
Massachusetts comparison
Massachusetts Rule 11 uses materially different certification and enforcement language and does not contain the federal 21-day safe harbor.
Identify which issues are triable to a jury as of right. Ordinarily serve and file the demand no later than 14 days after service of the last pleading directed to the issue. Waiver and discretionary relief are separate questions. A mixed request for money and an injunction requires issue-level analysis.
How to navigate it
Beacon Theatres protects jury determination of common legal issues against displacement through prior equitable adjudication. Do not wait until trial preparation to identify jury issues.
Massachusetts comparison
Massachusetts Rule 38 uses a 10-day demand period and the Commonwealth's constitutional/statutory foundation.
A noticed preliminary injunction ordinarily requires likely success, likely irreparable harm absent relief, favorable equities, and consistency with the public interest under Winter. A without-notice TRO adds specific evidentiary and attorney-certification requirements; federal duration is ordinarily at most 14 days, subject to the rule's extensions. Consider security, precision, persons bound, and preservation of jury rights if the hearing is consolidated with trial.
How to navigate it
Identify the threatened event, why a later money award may not repair it, and a narrower available order.
Massachusetts comparison
Massachusetts Rule 65 places TRO provisions in subsection (a), ordinarily uses 10 days, and expressly permits good-cause relief from security.
Packaging Industries frames the Massachusetts preliminary-injunction balance.
Serve summons and complaint through an authorized person and a method appropriate to the defendant. The ordinary federal service period is 90 days, subject to exceptions and extensions. A timely waiver changes the answer timetable without waiving personal-jurisdiction or venue objections. Filing proof of service and accomplishing service are distinct.
How to navigate it
Where were the papers left, who received them, and what authority or residential connection did that person have? Mullane asks whether the method was reasonably calculated to inform; it does not erase rule-specific service requirements.
Massachusetts comparison
Massachusetts Rule 4 has its own authorized-server provisions and Rule 4(j)'s 90-day framework; it should not be replaced wholesale with federal Rule 4.
The ordinary federal answer period after service is 21 days, with special rules for waiver, government defendants, and motions. A timely Rule 12 motion ordinarily changes the response deadline. Personal jurisdiction, venue, process, and service objections can be lost through omission from the first available Rule 12 response. Failure to state a claim and required-party objections have different preservation rules; subject matter jurisdiction cannot be created by waiver.
How to navigate it
Examine the actual first motion and answer, not merely whether the lawyer eventually raised an objection.
Massachusetts comparison
Massachusetts ordinarily uses 20 days to respond and 10 days after notice of denial/postponement of a Rule 12 motion, rather than the federal 14-day post-motion period.
Failure-to-state-a-claim review ordinarily tests legal sufficiency on the permitted pleading record. If outside materials are presented and not excluded on a Rule 12(b)(6) or 12(c) motion, conversion requires a reasonable opportunity to present pertinent Rule 56 material. Attached instruments, incorporated documents, and judicial notice require careful treatment; a disputed factual narrative is not made true by attaching it to a motion.
How to navigate it
Ask the court to identify the procedural vehicle and record it is using. Iqbal concerns pleading sufficiency; Celotex concerns evidence.
Massachusetts comparison
Massachusetts conversion language appears within its Rule 12(b)/(c), not a federal-style Rule 12(d) subdivision.
Respond fairly to allegations through admissions, denials, or the permitted statement of insufficient knowledge. Failure to deny can admit allegations, except those relating to damages. Affirmative defenses such as release, limitations, and claim preclusion must be affirmatively stated; denying an element is analytically different.
How to navigate it
“The product did not fail” disputes the claim; “the claim was released” invokes a separate avoidance. Identify the governing allocation of proof rather than assuming all defenses work alike. Later amendment may cure an omission, but prejudice, scheduling, and controlling precedent matter.
Massachusetts comparison
Massachusetts Rule 8 follows the same broad separation; use its text and local authority for specific consequences.
Rule 15, with Rule 16 when a scheduling deadline has passed
Working rule
Distinguish amendment as of course, amendment by consent/leave, amendment to conform to trial evidence, and supplementation for later events. Leave is ordinarily freely given, but delay, prejudice, bad faith, and futility matter. Relation back has separate requirements; a federal party-change amendment requires timely notice and the specified knowledge concerning a mistake.
How to navigate it
Foman addresses unjustified denial of leave; Krupski focuses the party-mistake inquiry on what the prospective defendant knew or should have known. Federal Rule 15(c)(1)(A) also requires consideration of relation back under applicable limitations law.
Massachusetts comparison
Massachusetts Rule 15 uses different amendment timing and expressly broader party-change relation-back wording.
Failure to plead or otherwise defend can lead to entry of default; judgment is a further step. A timely pending defensive motion is not “no answer” in the chart's practical sense. Distinguish a sum certain from damages needing proof, and give required notice to a party that appeared. Default judgment cannot exceed the kind or amount demanded. Entry of default can be set aside for good cause; a final default judgment invokes Rule 60.
How to navigate it
Verify service, jurisdiction, dates, appearance, and requested relief before discussing the merits. Peralta shows why absence of notice cannot be excused merely because a merits defense appears weak.
Massachusetts comparison
Massachusetts Rule 55 has its own procedures; Rule 55.1 adds special requirements for certain consumer-debt defaults.
A claim against an opposing party existing when the pleading is served is ordinarily compulsory if it arises from the same transaction or occurrence and the rule's other requirements are satisfied; specified exceptions apply. Other counterclaims may be permissive. Joinder permission does not resolve jurisdiction.
How to navigate it
An unpaid invoice from the disputed installation may belong in the answer; a separate older loan requires a different relationship analysis. Ask whether the claim had matured and whether another action was pending when this action began. The advisory notes connect omission of a compulsory counterclaim to later preclusion.
Massachusetts comparison
Massachusetts Rule 13 has its own text and court-specific provisions; identify the state court and check the operative subdivision before assuming identical compulsory treatment.
A crossclaim runs against a coparty and requires the specified transaction/property connection. Ordinary impleader brings in a nonparty who may owe the defending party all or part of its liability to the original claimant. Merely alleging that someone else is directly liable to the plaintiff is not ordinary Rule 14 derivative liability. Federal leave is required if the third-party complaint is filed more than 14 days after service of the original answer.
How to navigate it
Draw the indemnity or contribution obligation separately from the injury claim. Owen supplies the jurisdiction warning for a plaintiff's later direct claim.
Massachusetts comparison
Massachusetts Rule 14 instead permits impleader without leave when the third-party complaint is served within 20 days after the original answer is served.
Permissive joinder, misjoinder, and separate trials
C. Structuring parties and claims
Rules 18, 20, 21, 42
Working rule
Rule 18 broadly permits claims against an opposing party. Rule 20 party joinder requires the transaction/occurrence connection and a common question. Rule 21 permits adding/dropping parties or severance on just terms; misjoinder alone does not justify dismissing the action. Separate trials under Rule 42 differ from severance into separate actions.
How to navigate it
Similar equipment is a starting fact, not a substitute for the Rule 20 connection. Compare efficiency with confusion and prejudice. Hain Celestial cautions against using Rule 21 to override the plaintiff's proper joinder and preserved choice of a state forum in the circumstances it addressed.
Practise it
A1 / B3 / C3 — Test shared transactions and questions, then consider severance or separate trial.
First determine whether the absent person is required: complete relief among existing parties, impairment of a claimed interest, or a substantial risk of multiple/inconsistent obligations may matter. Then ask whether joinder is feasible. If not, apply Rule 19(b)'s equitable factors to decide whether the case can proceed or must be dismissed.
How to navigate it
Inconsistent factual outcomes are not automatically inconsistent obligations. An absent co-owner whose property rights an injunction would determine raises a different problem from another possible tortfeasor. Temple holds that joint tortfeasors are not required merely because they may share liability.
Massachusetts comparison
Massachusetts Rule 19 supplies the state procedural test.
Establish numerosity, commonality, typicality, and adequacy, then the relevant Rule 23(b) category. Damages classes under (b)(3) require predominance and superiority, with notice and opt-out protections. Injunctive classes under (b)(2) require relief appropriate to the class as a whole. Settlement still requires the applicable certification and approval safeguards.
How to navigate it
Wal-Mart asks whether a common contention can generate a common answer; Amchem exposes conflicts between differently situated groups. CAFA generally adds more than $5 million aggregate controversy, minimal diversity, and a 100-member threshold, subject to statutory exceptions.
Massachusetts comparison
Massachusetts Rule 23 has a different structure: its (b) requires predominance and superiority; do not import the federal three-category scheme.
A stakeholder facing competing claims to one obligation or fund may seek a single determination. Rule interpleader needs an independent jurisdictional basis. Statutory interpleader ordinarily requires at least $500 in value, adverse claimants with minimal diversity, and the required deposit or bond; it provides distinct venue and service provisions.
How to navigate it
Identify the actual stake and competing entitlements. An insurance limit is not permission to take over every related tort case. Tashire permits the fund-centered proceeding while limiting the injunction's reach.
Massachusetts comparison
Massachusetts Rule 22 is a state procedural vehicle; federal statutory jurisdiction and nationwide process do not follow it into state court.
Intervention is an outsider's request to enter: distinguish an entitlement based on an inadequately protected interest from permissive intervention. Check timeliness and jurisdiction. Death may require substitution if the claim survives; transfer of an interest does not always require replacing the original party.
How to navigate it
An insurer claiming subrogation and an observer wanting to help are differently situated. Under federal Rule 25(a), examine the statement noting death and proper service before starting the 90-day substitution clock. Taylor warns against assuming that a nonparty's similar interests alone make a judgment binding.
Massachusetts comparison
Massachusetts has corresponding but independently worded rules.
Scheduling, planning, and multidistrict management
D. Developing the record
Rules 16, 16.1, 26(f)
Working rule
Plan discovery around disputed issues; scheduling orders constrain amendments, discovery, and motions and ordinarily require good cause to modify. The 2025 changes encourage early agreement about describing withheld privileged/work-product material. New Rule 16.1 organizes initial management of transferred multidistrict litigation; MDL is not class certification.
How to navigate it
Ask what needs to be learned first to avoid unnecessary work. If related federal actions are transferred for coordinated pretrial proceedings, identify which claims remain separate.
Massachusetts comparison
Massachusetts Rule 26 does not impose the same universal federal initial-disclosure/Rule 26(f) scheme; standing orders and case-specific directions are essential.
Federal discovery concerns nonprivileged matter relevant to a claim or defense and proportional to the needs of the case. Consider importance, stakes, access, resources, likely benefit, and burden. Discoverability does not require trial admissibility. A protective order requires a supported showing, not simply discomfort with disclosure.
How to navigate it
Explain why each requested category bears on an issue and whether narrower sources will work. The current federal rule does not use “reasonably calculated to lead” as its scope formula.
Massachusetts comparison
Massachusetts Rule 26 retains different subject-matter language while providing limitations and protective orders; federal wording should not be copied into a Massachusetts rule quotation.
Attorney-client privilege and work product protect different things. Ordinary work product may be discoverable on substantial need and undue hardship; opinion work product receives stronger protection. Underlying facts do not become privileged simply because they were communicated to counsel. Identify testifying versus consulting experts, required disclosures, and supplementation.
How to navigate it
Hickman protects litigation preparation; Upjohn distinguishes protected communications from the facts themselves. Seek an appropriate privilege log/protocol and consider a Rule 502(d) order for inadvertent disclosure risk.
Massachusetts comparison
Massachusetts expert disclosure and discovery mechanisms differ from automatic federal report practice.
Written questions go to parties, not nonparty witnesses. Federal interrogatories ordinarily are limited to 25, including discrete subparts, absent stipulation or leave. Answers must be under oath and objections specific; a business-records response must satisfy the rule rather than merely point to an undifferentiated archive.
How to navigate it
Use interrogatories to identify knowledgeable people, contentions, and record locations; use a different device to question a nonparty. Count substance rather than punctuation. The rule texts are the principal authorities for these mechanics.
Massachusetts comparison
Massachusetts Rule 33 uses a 30-interrogatory framework and its own enforcement procedures, so federal limits and default consequences are not portable.
Documents, electronically stored information, and inspection
D. Developing the record
Rule 34
Working rule
A party can request relevant documents, ESI, tangible things, testing, or entry onto land within another party's possession, custody, or control. Requests must describe items with reasonable particularity. Address production form, organization, specific objections, and whether responsive material is withheld. Nonparty production ordinarily uses Rule 45.
How to navigate it
Separate “our contractor holds it” from whether the party has legal/practical control under governing law. Ask for source data or metadata only when its value can be explained. Destructive testing warrants conditions preserving the other side's ability to investigate.
Massachusetts comparison
Massachusetts Rule 34 also addresses ESI and inspection, but its precise response language controls in state court.
Depositions may examine parties or nonparties; compulsion differs. Federal defaults include ten depositions per side grouping specified by the rule and one day of seven hours, subject to stipulation/order. A Rule 30(b)(6) notice describes organizational topics with reasonable particularity; the organization designates and prepares witnesses on information reasonably available to it.
How to navigate it
Choose between personal recollection and organizational knowledge. Objections ordinarily do not halt answers; instructions not to answer have limited grounds. An unprepared organizational witness is not excused merely by lack of personal involvement.
Massachusetts comparison
Massachusetts Rule 30 was amended in 2025; consult its current text and Rule 30A rather than assume every federal recording or duration provision applies.
Before suit, a verified petition must establish an expected federal-cognizable action that cannot presently be brought, the testimony to preserve, and why preservation is needed. Notice and an order are required. A separate provision concerns preservation pending appeal.
How to navigate it
An identified witness facing a serious risk of becoming unavailable differs from a request to question people merely to find out whether a lawsuit exists. If an action can already be filed, explain why ordinary filing and expedited discovery are not the appropriate path. This entry is based primarily on the rule's express conditions, not a claim that pre-suit discovery is generally available.
Practise it
C1 — Explain why evidence must be perpetuated before an action can presently be brought.
Rule 28 addresses who may administer and record deposition testimony, foreign procedures, and disqualifying interests or relationships. Rule 29 permits procedural stipulations but requires court approval for an extension that would interfere with court-ordered discovery, motion, or trial dates.
How to navigate it
Convenience does not answer whether an officer is qualified or disqualified. A remote examination needs a defensible plan for oath, recording, exhibits, participation, and location. Counsel cannot privately alter the court's schedule merely by agreeing with each other.
Massachusetts comparison
Massachusetts rules and local orders must be checked separately for a state deposition.
Rule 31 uses pre-served written questions administered through the deposition process, including cross-questions; it is not an interrogatory answered privately by a party. Rule 32 governs use of depositions in court, including impeachment, qualifying party/organizational testimony, and unavailable witnesses, subject to its conditions and evidence law.
How to navigate it
Cost savings may come at the expense of adaptive follow-up. Ask whether the opponent had notice/opportunity to participate and whether the offered segment requires contextual completion. Obtaining a transcript does not automatically make every statement in it admissible at trial.
Massachusetts comparison
Rule texts supply the mechanics; Massachusetts has corresponding Rules 31–32.
A condition must be in controversy and good cause shown. The person must be a party or within a party's custody/legal control; the order must define the examiner, scope, manner, conditions, time, and place. Report exchange can have specified privilege consequences.
How to navigate it
Schlagenhauf rejects examinations supported merely by conclusory allegations or ordinary relevance. Identify why records or narrower examinations are insufficient.
Massachusetts comparison
Massachusetts amended Rule 35 in 2023 to use a suitably licensed or certified examiner following Ashe; the outdated assumption that the examiner must fit a narrow physician category should not control the exercise.
A party may request admissions concerning facts, application of law to fact, opinions about either, and document genuineness. The federal response period ordinarily is 30 days. Unanswered matters become admitted; admissions are conclusive in the action unless withdrawal/amendment is permitted. Withdrawal considers presentation of the merits and prejudice in maintaining the action or defense.
How to navigate it
Distinguish authenticating a service log from admitting that every entry is accurate or that the defendant was negligent. Genuine inability to admit requires reasonable inquiry. A late-response dispute should address the withdrawal standard and actual reliance, not simply whether the admission hurts.
Massachusetts comparison
Massachusetts uses its own Rule 36; the procedural effect is different from an ordinary discovery answer.
Subpoenas can command testimony, documents/ESI, or inspection, subject to service, notice, geographic limits, privilege, and protection from undue burden. A federal subpoena issues from the court where the action is pending, but disputes ordinarily belong to the court for the place of compliance, subject to transfer provisions.
How to navigate it
A nonparty cloud provider cannot simply be served with Rule 33 interrogatories. Distinguish where a subpoena can be served from where compliance can be compelled. Identify burden and significant expense to a nonparty.
Massachusetts comparison
Massachusetts subpoena practice is governed by its own Rule 45 and applicable interstate process, not automatic nationwide federal authority.
Match the remedy to the violation: motion to compel, expense shifting, exclusion, established facts, striking pleadings, dismissal, or default have different triggers. Some remedies require a violated order; others address specified failures without one. Certification of a good-faith conference matters where required.
How to navigate it
National Hockey League upheld dismissal for extreme discovery misconduct; it does not make every late response grounds for terminating a case. Identify responsibility, justification, prejudice, and a fitting remedy.
Massachusetts comparison
Massachusetts Rule 37 has its own text and procedures; do not import the federal disclosure-exclusion machinery without checking.
Identify ESI that should have been preserved in anticipation or conduct of litigation, lost because reasonable steps were not taken, and not restorable or replaceable through additional discovery. Prejudice can justify measures no greater than necessary to cure it. An adverse presumption/instruction or dismissal/default under (e)(2) requires intent to deprive another party of the information's use.
How to navigate it
A routine deletion setting neither conclusively excuses loss nor proves intent. Ask when litigation became reasonably foreseeable, who knew, what hold steps were feasible, and whether another copy exists.
Massachusetts comparison
Physical evidence and Massachusetts spoliation require their own authority.
Kippenhan is a Massachusetts physical-evidence anchor, not a substitute for federal Rule 37(e).
A movant must show no genuine dispute of material fact and entitlement to judgment as a matter of law. The opponent must identify a supported material dispute, not rest on allegations. Materials need a route to admissible presentation. Rule 56(d) allows a supported explanation of why essential facts cannot yet be presented and what discovery is needed. Partial summary judgment can narrow issues.
How to navigate it
Celotex permits a properly supported absence-of-proof route; Anderson connects sufficiency to the trial burden and reserves credibility for the factfinder. Denial ordinarily leaves the matter for further proceedings; it does not establish liability.
Massachusetts comparison
Massachusetts Kourouvacilis asks whether the opponent has a reasonable expectation of proving an essential element.
Jury selection and challenges are distinct from the verdict rule. A federal civil jury starts with at least six and no more than twelve members; absent stipulation, the verdict is unanimous and returned by at least six. Polling may reveal lack of agreement before discharge.
How to navigate it
Do not treat a simple majority as an ordinary valid federal verdict. c. The chart's “majority” needs this precise fraction. The difference makes a useful forum-switch exercise even when the underlying evidence is unchanged.
Massachusetts comparison
Massachusetts G.L.
234A, §68B permits five-sixths agreement; Massachusetts Rule 48 addresses its own jury arrangements.
Rule 43; applicable substantive law and evidence rules
Working rule
The burden of production asks whether sufficient evidence has been introduced to permit decision by the factfinder; persuasion asks whether the designated party has proved the issue to the required degree. Preponderance is ordinarily more likely than not for the proposition at issue, not a global judgment that everything the plaintiff says is true.
How to navigate it
Assign the burden to each element and defense. Addington illustrates clear-and-convincing proof in civil commitment; Winship concerns proof beyond a reasonable doubt in juvenile delinquency, not ordinary civil damages. Anderson explains why a heightened burden can matter before trial. The three standards in the chart should be taught through their distinct legal settings.
General verdicts, special verdicts, and interrogatories
E. Decisions on the record and at trial
Rule 49
Working rule
A special verdict asks for findings on specified factual issues; a general verdict with questions combines an overall outcome with written findings. The rule prescribes different responses to missing findings and inconsistent answers/verdicts. Drafting the form can determine whether the record reveals what the jury actually decided.
How to navigate it
Separate defect, causation, claimant fault, and damages without asking contradictory questions. If answers conflict, inspect the precise type of verdict and available options before jury discharge. A verdict-form preference alone is not the legal standard.
Massachusetts comparison
Massachusetts Rule 49 has corresponding devices; timely objections and the governing appellate cases matter.
Parties request instructions, receive an opportunity to object, and must preserve alleged error in the manner the rule specifies. State the disputed instruction or omission and the grounds. Federal plain-error review is a limited exception, not a substitute for an objection.
How to navigate it
Ask whether the proposed language correctly assigns elements, burdens, and the permissible use of evidence. An instruction that resolves a genuinely disputed fact is different from one explaining its legal relevance. Connect the requested instruction to CP-43 and the verdict form in CP-44.
Massachusetts comparison
Massachusetts Rule 51 also governs argument and instruction practice and uses its own preservation language.
In a jury trial, after a party has been fully heard on an issue, the court may rule if a reasonable jury would lack a legally sufficient evidentiary basis to find for that party. The motion must be made before submission to the jury and specify the judgment sought and supporting law/facts.
How to navigate it
Reeves requires consideration of the record under the correct favorable-inference approach without credibility weighing. A judge's belief that one witness is probably more reliable does not alone establish legal insufficiency.
Massachusetts comparison
Massachusetts calls its mechanism a directed verdict and specifies its own points for making the motion.
A federal renewed motion ordinarily must be filed within 28 days after entry of judgment, or the specified jury-discharge trigger if no verdict was returned. It renews a properly preserved Rule 50(a) challenge; it is not a fresh opportunity to invent a different evidentiary ground. A new-trial request may accompany it.
How to navigate it
Unitherm shows the consequences of failing to renew a sufficiency challenge. Dupree distinguishes a purely legal issue resolved at summary judgment, which need not be renewed under Rule 50 to preserve appeal.
Massachusetts comparison
Massachusetts JNOV uses a 10-day service deadline and a directed-verdict motion at the close of all evidence.
In a federal bench trial the judge finds facts and states legal conclusions. Rule 52(c) permits judgment on partial findings after a party has been fully heard; the judge acts as factfinder rather than applying Rule 50's jury-sufficiency posture. Appellate review generally separates clear-error fact review from legal review.
How to navigate it
Do not file a jury-trial motion simply because the chart shows Rule 50 next to “trial.” Ask whether the judge made the findings needed to explain the result.
Massachusetts comparison
Massachusetts Rule 52 differs in organization and includes District Court/BMC provisions; its subsection (c) is not the federal judgment-on-partial-findings rule.
Distinguish a verdict, an order disposing of a motion, and entry of judgment. An order resolving fewer than all claims or parties ordinarily remains interlocutory absent a proper Rule 54(b) determination and direction. Rule 58's separate-document and entry rules affect timing.
How to navigate it
List every remaining claim and party before calling the case over. An “allowed” arrow might resolve one issue or the entire action. Hain Celestial illustrates why an interlocutory dismissal remains subject to review with final judgment.
Massachusetts comparison
Massachusetts Rule 58 and its appellate rules govern state timing independently.
A federal plaintiff ordinarily may dismiss by notice before the opponent serves an answer or summary-judgment motion, or by a stipulation signed by all parties who appeared, subject to exceptions. Later dismissal ordinarily requires a court order. Counterclaims, terms, the two-dismissal rule, and the difference between with/without prejudice matter. Involuntary dismissal has stated exceptions to its default merits effect.
How to navigate it
A pending Rule 12 motion is not an answer for this federal notice mechanism. Ask which claims the document actually dismisses and what the order says. Semtek cautions against treating Rule 41's “on the merits” language as the entire interstate claim-preclusion analysis.
Distinguish a new trial based on qualifying trial error or other recognized grounds from judgment based on legal insufficiency. A federal Rule 59 motion must be filed within 28 days after entry of judgment; the court's authority and treatment of the record differ from Rule 50.
How to navigate it
Identify the challenged occurrence: erroneous instruction, evidentiary ruling, prejudicial misconduct, or weight/damages issue. Explain why it could have affected the result. Unitherm helps separate proper post-trial requests from an unpreserved appellate sufficiency challenge.
Massachusetts comparison
Massachusetts Rule 59 ordinarily requires service within 10 days; do not treat that as the federal filing deadline.
Clerical corrections differ from substantive relief. Rule 60(b) identifies mistake/excusable neglect, newly discovered evidence, fraud/misconduct, voidness, specified changed circumstances, and other extraordinary reasons. Motions must meet their ground-specific standards and timing: reasonable time generally, with a one-year cap for (b)(1)–(3). It is not an unrestricted appeal substitute.
How to navigate it
A judgment entered without constitutionally adequate notice raises a different question from a lawyer overlooking a deadline. Peralta supplies the notice example. Ask when the evidence could reasonably have been discovered, what prevented timely action, and whether the asserted ground fits.
Massachusetts comparison
Massachusetts Rule 60 is an independent text; its filing does not automatically suspend enforcement or reset appeal time.
Appeals ordinarily await final judgment, with specified interlocutory routes such as qualifying injunction orders. A timely notice is essential; ordinary federal civil timing is 30 days, with 60 days for qualifying United States-party cases and rules governing tolling motions. Identify the standard of review and whether an error affected substantial rights.
How to navigate it
Dupree distinguishes a preserved purely legal question from a factual sufficiency challenge. A denied summary-judgment motion is not ordinarily an immediate appeal ticket.
Massachusetts comparison
Massachusetts appellate Rule 4 separately governs state appeals; post-trial service/filing and tolling requirements must be read together.
First identify whose judgment it is and which law determines its effect. Claim preclusion can bar a later claim arising from the same legally defined transaction between qualifying parties after a valid final judgment. Issue preclusion concerns an issue actually litigated, determined, essential, and subject to a fair opportunity to litigate.
How to navigate it
A default may have claim-preclusive consequences without ordinary actually-litigated issue preclusion. Semtek addresses federal diversity judgments; Parklane addresses discretionary offensive nonmutual issue preclusion; Taylor rejects broad virtual representation of nonparties. A shared interest or friendship alone does not bind an absent claimant.
Massachusetts comparison
Massachusetts Kobrin distinguishes the two doctrines under state law.
A money judgment does not collect itself. Federal Rule 62 ordinarily supplies a 30-day enforcement stay, with exceptions including injunction-related judgments; a further stay may require appropriate security. Rule 69 generally uses state execution procedure unless federal law governs and permits asset discovery. Rule 70 addresses judgments requiring specified acts.
How to navigate it
Distinguish appeal from a stay, damages from injunctive compliance, and the judgment debtor from a related entity. Identify property and permissible process before proposing collection. This is an orientation to the judgment's consequences, not a full collection-law module.
Massachusetts comparison
Massachusetts has its own stay/execution rules; do not assume federal timing.
