Defeating a Rule 9(b) motion: how to plead fraud with particularity

You filed a complaint that includes a fraud claim. The defense responded with a Rule 9(b) motion arguing the fraud allegations are not pleaded with particularity. Your response brief has to do three things: show the court that the complaint already supplies the who, what, when, where, and how of the alleged fraud; explain why the heightened standard does not transform Rule 9(b) into a probability requirement; and, if any pocket of the pleading is genuinely thin, ask for leave to amend in the alternative so the case does not die on a curable defect.

Rule 9(b) is the most frequently misunderstood pleading rule in federal court. Defendants routinely overstate what it demands, and plaintiffs routinely undersell what their complaints already provide. The response brief that walks the judge through the rule as the Supreme Court and the leading circuits have actually applied it almost always survives.

What Rule 9(b) actually requires

Federal Rule of Civil Procedure 9(b) provides that "[i]n alleging fraud or mistake, a party must state with particularity the circumstances constituting fraud or mistake. Malice, intent, knowledge, and other conditions of a person's mind may be alleged generally." That second sentence matters as much as the first. Rule 9(b) heightens the standard for the circumstances of the fraud, not for the defendant's mental state.

The circuits have converged on a standard formulation: the complaint must allege the who, what, when, where, and how of the alleged fraud. The leading articulation is Vess v. Ciba-Geigy Corp. USA, 317 F.3d 1097, 1106 (9th Cir. 2003), which held that a fraud allegation under Rule 9(b) "must be accompanied by the who, what, when, where, and how of the misconduct charged." Other circuits use slightly different language but reach the same place: the defendant must have enough information about the alleged misrepresentation to investigate and defend it.

What Rule 9(b) does not require:

1. Detailed evidentiary proof of fraud. The rule is a pleading rule, not a summary-judgment standard.
2. A complete recitation of every misrepresentation. A representative sample of the fraudulent statements is usually enough when the alleged scheme involved repeated conduct.
3. Direct evidence of the defendant's state of mind. Scienter may be pleaded generally under the second sentence of the rule.
4. Allegations that would only be available after discovery. Courts repeatedly hold that the particularity standard is relaxed where facts are peculiarly within the defendant's knowledge.

A response brief that opens by quoting Rule 9(b) in full, including the "generally" clause, frames the motion correctly from the start. Defense briefs love to quote only the first sentence.

Twombly and Iqbal set the floor, not the ceiling

Defendants sometimes cite Bell Atlantic Corp. v. Twombly, 550 U.S. 544 (2007), and Ashcroft v. Iqbal, 556 U.S. 662 (2009), as if those decisions imposed an additional layer of scrutiny on Rule 9(b) claims. They do not. Twombly and Iqbal set the general plausibility floor for all federal claims. Rule 9(b) sits on top of that floor for the specific issue of fraud particularity. A fraud complaint must clear both bars, but clearing them does not require anything more than the rules themselves describe.

The Supreme Court emphasized in Iqbal itself that the second sentence of Rule 9(b) controls scienter pleading: "Rule 9 . . . excuses a party from pleading discriminatory intent under an elevated pleading standard. It does not give him license to evade the less rigid, though still operative, strictures of Rule 8." 556 U.S. at 686-87. The takeaway for plaintiffs is the opposite of what defendants usually argue: scienter for non-securities fraud is pleaded under Rule 8's plausibility standard, not under any heightened particularity rule.

Tellabs does not control non-securities fraud

The most common defense overreach is to import the strong-inference scienter standard from Tellabs, Inc. v. Makor Issues & Rights, Ltd., 551 U.S. 308 (2007), into ordinary common-law or statutory fraud claims. Tellabs is a Private Securities Litigation Reform Act case. The PSLRA imposed a uniquely demanding scienter standard on securities-fraud claims: the complaint must "state with particularity facts giving rise to a strong inference that the defendant acted with the required state of mind." 15 U.S.C. § 78u-4(b)(2)(A). The Supreme Court read "strong inference" to require an inference of scienter "cogent and at least as compelling as any opposing inference of nonfraudulent intent." Tellabs, 551 U.S. at 314.

That standard is statutory. It applies only to PSLRA claims. It does not apply to common-law fraud, consumer-protection fraud, RICO mail-and-wire-fraud predicates, or any other fraud claim outside the PSLRA. Defense briefs that cite Tellabs in non-securities cases are smuggling a statutory standard into a doctrinal context where it does not belong. The response brief should call this out by name: identify the statutory basis of Tellabs, explain that the claim at issue is not a PSLRA claim, and cite Rule 9(b)'s "generally" clause as the controlling scienter standard.

Pleading the who, what, when, where, and how

The strongest Rule 9(b) responses do not argue particularity in the abstract. They walk the court through a table of the complaint's allegations and match them to the elements of the Vess formulation.

Who

Identify the speaker of each alleged misrepresentation. Where the defendant is a corporation, identify the individual who made the statement or, if that individual is not yet known, identify the corporate channel through which the statement was made (a press release, an annual report, a customer-service script). When the speaker is genuinely unknown pre-discovery and the information is in the defendant's exclusive control, plead that fact and cite authority relaxing the standard.

What

Quote or paraphrase each alleged misrepresentation. The complaint should make clear what was said and why it was false. A complaint that alleges only "Defendant made false statements about the product" does not satisfy Rule 9(b). A complaint that alleges "Defendant's October 2024 product brochure stated the device was 'tested to a 10-year service life,' when in fact internal testing had shown failure rates above 30% after 18 months" does.

When

Date the statements. Approximate dates ("in or about October 2024") are usually fine when more precision is not available, but the complaint should pin down the time frame closely enough that the defendant can investigate.

Where

Identify the medium and location. A statement in a TV commercial, a packaging label, a sales pitch in a specific city, an email to a specific recipient: each of these is a "where" allegation.

How

Explain how the statement was fraudulent. This is where the complaint connects the alleged false statement to falsity. If the statement was literally true but misleading, plead the omission that made it misleading. If the statement was an opinion or projection, plead the facts showing it was not honestly held.

A clean response brief reproduces this table, with paragraph citations to the complaint. The judge can verify particularity at a glance.

Fraud-by-omission has a relaxed standard

Where the alleged fraud is an omission (failure to disclose a material fact), most circuits relax the Vess "who, what, when, where, and how" formulation. The reason is straightforward: you cannot plead the exact circumstances of a statement that was never made. The complaint instead must plead the content of the omission, the defendant's duty to disclose, and the defendant's knowledge of the omitted fact.

The defendant's duty to disclose typically arises from a fiduciary or confidential relationship, a partial disclosure that was misleading without the omitted fact, or a statutory duty. The response brief should identify the source of the duty and the specific facts that triggered it. Where the complaint pleads partial disclosure, identify the disclosed statement, identify the omitted fact, and explain why the omission made the disclosed statement misleading.

Defense briefs sometimes argue that fraud-by-omission requires the same who-what-when-where-how detail as affirmative-misrepresentation fraud. The response should distinguish the two theories and cite circuit authority adopting a relaxed standard for omissions.

Pleading scienter

Rule 9(b)'s second sentence allows knowledge, intent, and other states of mind to be alleged generally. Under Iqbal, "generally" means under the Rule 8 plausibility standard rather than under heightened particularity. The complaint must allege facts from which the court can plausibly infer that the defendant knew the statement was false or acted with reckless disregard for its truth.

Useful scienter facts include:

1. Internal documents or communications showing the defendant knew the truth at the time of the statement.
2. The defendant's position within the company (a CEO discussing core operations is more plausibly knowledgeable than a low-level employee).
3. The magnitude of the alleged misrepresentation relative to the defendant's business (a misrepresentation about a flagship product is more plausibly known to senior officers than a misrepresentation about a fringe line).
4. Prior litigation, regulatory action, or whistleblower reports putting the defendant on notice.
5. Personal benefit to the defendant, such as stock sales or compensation tied to the misstated metric.

The response brief should identify the complaint paragraphs that allege each of these facts and explain how they support a plausible inference of scienter. Where the complaint cites internal documents or witness statements, summarize what the documents show or what the witnesses are alleged to have heard.

When to seek leave to amend

Even a well-pleaded fraud complaint sometimes has a pocket the court finds thin. The response brief should ask in the alternative for leave to amend. Rule 15(a)(2) provides that leave shall be "freely give[n] when justice so requires," and the Supreme Court has confirmed that leave is appropriate absent undue delay, bad faith, repeated failed amendments, undue prejudice, or futility. See Foman v. Davis, 371 U.S. 178, 182 (1962).

Most first-round Rule 9(b) dismissals are with leave to amend. Plaintiffs who have not previously amended a fraud claim have a strong claim to at least one chance to cure. The response brief should state, in the conclusion, that if the court finds any deficiency the plaintiff requests leave to amend, and should briefly describe the kind of additional facts that could be added (for example, dates and identities discovered through pre-suit investigation that were omitted from the initial filing).

Where possible, attach a proposed amended complaint or a redline showing the proposed additions. A judge inclined to dismiss is far more likely to grant leave to amend than to enter a final judgment, especially when the proposed amendment is concrete.

Conley's notice-pleading legacy

Older decisions, especially in state courts following the federal model, sometimes cite Conley v. Gibson, 355 U.S. 41 (1957), for the proposition that a complaint should not be dismissed unless "it appears beyond doubt that the plaintiff can prove no set of facts in support of his claim." Id. at 45-46. Twombly expressly retired that formulation as the federal standard for Rule 8 pleading, 550 U.S. at 562-63, but Conley's underlying notice-pleading philosophy still informs many state pleading regimes and remains useful background for Rule 9(b) practice.

The point is not to cite Conley as governing law in federal court (it is not), but to remind the court that the federal pleading rules are designed to give defendants fair notice, not to require evidentiary proof at the threshold. Defense briefs that demand near-trial-quality detail under the banner of Rule 9(b) are asking for something neither Conley, Twombly, nor Iqbal requires.

How to brief the opposition

A Rule 9(b) response has a predictable structure.

Introduction

One or two paragraphs explaining what the fraud claim is, why the complaint pleads each element with particularity, and what the court should do. Quote a key allegation if it shows the particularity at once.

Statement of facts

A factual narrative drawn from the complaint, with paragraph citations. Resist the urge to argue here.

Legal standard

A short section that quotes Rule 9(b) in full, identifies Vess (or the controlling circuit case) for the who-what-when-where-how formulation, cites Iqbal for the rule that scienter is pleaded under Rule 8, and explains that Tellabs applies only to PSLRA claims.

Argument

Organized claim-by-claim. For each fraud claim:

1. State the elements.
2. Walk through the who-what-when-where-how, with paragraph citations.
3. Address scienter under Rule 8 plausibility.
4. Address the specific defense arguments directed at that claim.

Conclusion

Ask the court to deny the motion. In the alternative, ask for leave to amend, and, if practical, attach the proposed amended pleading.

What sinks Rule 9(b) responses

The most common errors:

Conceding the strong-inference standard. Plaintiffs sometimes try to plead under the Tellabs standard out of caution. This is a mistake. By conceding that Tellabs applies, the plaintiff invites the court to evaluate scienter under a standard that does not control. Push back: identify the controlling rule and apply it.

Treating Rule 9(b) as a higher form of Iqbal. Rule 9(b) and Iqbal are different requirements. Rule 9(b) addresses the circumstances of the fraud; Iqbal addresses the plausibility of the inferences the complaint asks the court to draw. Run both analyses, and run them separately.

Ignoring the omission/affirmative distinction. Fraud-by-omission claims survive Rule 9(b) under a relaxed standard. A response brief that argues omission claims under the strict affirmative-misrepresentation formula concedes ground it did not have to concede.

The bottom line

A Rule 9(b) response succeeds when the brief: quotes the full rule (including the "generally" clause), identifies the who-what-when-where-how in the existing complaint, treats scienter as a Rule 8 question, distinguishes Tellabs and other PSLRA-specific authority, and asks for leave to amend in the alternative. It fails when the response writes in the abstract, accepts the defense's framing of the standard, or treats fraud-by-omission like an affirmative-misrepresentation claim.

Rule 9(b) is a particularity rule, not a probability rule. A complaint that pleads the circumstances of the alleged fraud with enough detail to let the defendant investigate and answer should survive. The response brief's job is to make the particularity already in the complaint visible to the court.
