Late last year, when we were putting together our massive post that collected and categorized every case that had ever judicially noticed an FDA document, we ran across the intriguing proposition that in deciding Rule 12 pleading-based motions, “allegations in a complaint are not credited where contradicted by judicially noticeable documents.” We cited several appellate decisions for that principle. The most recent one, Fuqua v. Santa Fe County Sheriff’s Office, 157 F.4th 1288 (10th Cir. 2025), stated:
The general rule prohibiting courts from considering evidence outside the complaint on a motion to dismiss has an[] exception: matters of which a court may take judicial notice. Judicial notice allows the court to accept a matter as proved without requiring the party to offer evidence of it. And taking judicial notice precludes a party from introducing contrary evidence and, in effect, directs a verdict against him as to the fact noticed.
Id. at 1298 (citations and quotation marks omitted). Fuqua cited a Supreme Court case for this point, Tellabs, Inc. v. Makor Issues & Rights, Ltd., 551 U.S. 308 (2007). The Supreme Court held in that case, that in adjudicating Rule 12(b)(6) motions, “courts must consider the complaint in its entirety, as well as other sources courts ordinarily examine” such as “matters of which a court may take judicial notice.” Id. at 322.
Other cases for this proposition include Sprewell v. Golden State Warriors, 266 F.3d 979 (9th Cir. 2001), affirming that in the 12(b)(6) context, courts “need not . . . accept as true allegations that contradict matters properly subject to judicial notice” or that “are merely conclusory, unwarranted deductions of fact, or unreasonable inferences.” Id. at 988 (citations omitted). The Sprewell decision has been particularly influential and has been followed by several other Ninth Circuit decisions. Readers of this post will notice a disproportionately high percentage of the cases discussed below are from Ninth Circuit district courts.
For additional appellate authority supporting the general proposition that judicial notice trumps contrary pleadings, see Jeffery v. City of New York, 113 F.4th 176, 179 (2d Cir. 2024) (affirming dismissal when considering“ all matters of proper judicial notice”) (citation and quotation marks omitted); Secured Mail Solutions LLC v. Universal Wilde, Inc., 873 F.3d 905, 913 (Fed. Cir. 2017) (“[i]n ruling on a 12(b)(6) motion, a court need not accept as true allegations that contradict matters properly subject to judicial notice”) (citation and quotation marks omitted); Clark v. Stone, 998 F.3d 287, 298 (6th Cir. 2021) (“this court may take judicial notice of public records, and we are not required to accept as true factual allegations that are contradicted by those records”) (citation omitted); Massey v. Ojaniit, 759 F.3d 343, 353 (4th Cir. 2014) (courts “need not accept allegations that contradict matters properly subject to judicial notice”) (citation and quotation marks omitted); Kaempe v. Myers, 367 F.3d 958, 963 (D.C. Cir. 2004) (“Nor must we accept as true the complaint’s factual allegations insofar as they contradict . . . matters subject to judicial notice”) (citation omitted); Gupta v. Wipro Ltd., 749 F. Appx. 94, 97 (3d Cir. 2018) (“Although we generally must accept as true the complaint’s factual allegations, this requirement does not apply when the allegations are contradicted by . . . matters subject to judicial notice.”) (citation and quotation marks omitted).
We decided to look for cases that apply the general proposition that courts need not accept as true allegations refuted by matters subject to judicial notice in the specific context of prescription medical product liability litigation. One such case is Plumlee v. Pfizer, Inc., 2014 WL 4275519 (N.D. Cal. Aug. 29, 2014), where the court took judicial notice of a drug’s FDA-approved labeling and certain changes to that labeling that also went through proper FDA regulatory channels. Id. at *4 & n.2. The court also took judicial notice of the existence of “dozens of exhibits submitted by Defendant” that “directly contradict Plaintiff’s claim.” Id. at 8. Those exhibits established that, contrary to the plaintiff’s allegations, she could not, as a “reasonable consumer,” have been “ignorant” of the issue she belatedly sought to litigate after the expiration of the statute of limitations. Id. at *8.
On appeal, the Ninth Circuit affirmed.
[T]he district court took judicial notice of an extensive record of documents − all publicly available during the relevant limitations periods − which discussed [the efficacy issues raised by plaintiff’s complaint]. The district court did not err in taking judicial notice of these documents. The judicially noticed documents either identified [the drug] specifically or referred to antidepressants generally. . . . Therefore, the district court properly rejected [plaintiff’s] allegation that no information questioning [the drug’s] efficacy existed within the three- and four-year limitations periods. . . to which a reasonably diligent consumer would have been exposed.
Plumlee v. Pfizer, Inc., 664 F. Appx. 651, 653-54 (9th Cir. 2016).
Chapman v. Abbott Laboratories, 930 F. Supp.2d 1321 (M.D. Fla. 2013), reached a similar result. In Chapman the plaintiff’s allegations about the drug’s warnings were directly contradicted by its FDA-approved labeling, which was subject to judicial notice.
[Plaintiff’s] claim is squarely contradicted by the . . . judicially-noticed drug label that does contain warnings. . . . This conflict renders implausible the failure to warn theory as currently pled in [plaintiff’s] strict liability and negligence counts. . . . [It is] clear that the overarching theme of [plaintiff’s] case is failure to warn, as evidenced by [plaintiff’s] counsel’s summary of the action in his response to the motion to dismiss. . . . Accordingly, the Court will grant the motion to dismiss insofar as it seeks dismissal of the strict liability and negligence counts.
Id. at 1323-24 (citation omitted).
Another example is De La Paz v. Bayer Healthcare LLC, 159 F. Supp.3d 1085 (N.D. Cal. 2016). Relying on judicially noticed FDA enforcement materials (Forms 483) the court dismissed the plaintiff’s manufacturing defect claims because they misconstrued the contents of those documents:
[T]o escape implied preemption [plaintiff] must allege that the irregularities documented in the Form 483s resulted in a manufacturing defect that caused her injuries. . . . [Plaintiff] has failed to allege such a manufacturing defect.
The complaint offers no description of the “non-conforming material” used in manufacturing the device, or how the use of that material caused a defect in the product itself. In fact, the Form 483 indicated that [defendant’s] contract manufacturer used the “non-conforming material” in a validation protocol, not in the actual manufacture of the product. Moreover, the report indicated that the manufacturer had erred by failing to adequately document the disposition of that material, not by using the material itself. [Plaintiff] has provided no basis for concluding that the failure to document the disposition of non-conforming material in a validation protocol caused a manufacturing defect in any . . . device.
Id. at 1094-95 (citations omitted). See also Id. at 1096, 1098 (additional dismissals of failure to train and express warranty claims due to contradiction with judicially noticed FDA documents).
Likewise, in Trisvan v. Heyman, 305 F. Supp.3d 381 (E.D.N.Y. 2018), the plaintiff alleged – falsely – “that there were no warnings about the relevant side-effects” with the defendant’s drug. Id. at 399 (emphasis original). Since the defendant’s judicially noticed warnings (and the Physician’s Desk Reference) belied that allegation, it was ignored and the aspect of the plaintiff’s complaint was dismissed:
In contrast to most other failure to warn cases, the adequacy of the warning in this action turns on its mere existence. Defendants, however, have offered FDA-approved labels as evidence of warnings provided to physicians contemporaneous with or predating Plaintiff’s use. . . . At the very least, these FDA labels list [specific warnings omitted]. Accordingly, Plaintiff’s failure to warn claims based on a lack of any warnings are dismissed with prejudice.
Id. at 400 (citations omitted). Accord Trisvan v. Heyman, 2018 WL 6573434, at *4-5 (E.D.N.Y. Dec. 13, 2018) (second dismissal for “allegations in a complaint that contradict or are inconsistent with judicially-noticed facts”) (footnote omitted).
In Carter v. Amgen, Inc., 2015 WL 13388039 (C.D. Cal. July 16, 2015), aff’d, 682 F. Appx. 620 (9th Cir. 2017), plaintiff repeatedly alleged, in conclusory function, that the relevant use of a drug was “contraindicated. Id. at 6. “[J]udicially noticed FDA labels” established that these allegations were untrue, and the claim was dismissed:
[T]he contraindicated allegation is directly contradicted by the FDA-approved labels that the Court has judicially noticed. . . . The labels each contain a section entitled “Contraindications”. . . . [discussion of labeled contraindications omitted] Thus, the Court need not accept as true the allegation that [the drug] was “contraindicated” for [decedent’s] use of the drug because the judicially noticed labels demonstrate that the allegation blatantly false.
Id. (citations and quotation marks omitted).
The same result occurred in Becker v. Cephalon, Inc., 2015 WL 5472311 (S.D.N.Y. Sept. 15, 2015). Plaintiff’s warning-related allegations were “squarely contradicted” by the drug’s judicially noticed labeling, requiring their dismissal:
While a court must generally accept a plaintiff’s factual allegations as true in evaluating a motion to dismiss, it need not accept as true allegations in a complaint that contradict or are inconsistent with judicially-noticed facts. Plaintiff’s allegations that [defendant] failed to warn of the risk [at issue] when taking [the drug] . . . are squarely contradicted by the [drug’s] label. . . . Because all of the alleged side effects described by Plaintiff are specifically indicated as potential side effects in the drug’s package insert, . . . Plaintiff’s strict liability and negligence products liability claims based on a failure to warn theory are foreclosed and must be dismissed.
Id. at *5-6 (citations and quotation marks omitted).
Those decisions are hardly all the examples we found of contradictions with judicially noticed material resulting in Rule 12 dismissal. Here are a bunch of other cases where FDA materials or other unimpeachable documents concerning FDA regulated products were judicially noticed and resulted in dismissal of claims, despite contrary pleaded allegations. Govea v. Medtronic, Inc., 2025 WL 3467214, at *13 (C.D. Cal. Nov. 26, 2025) (judicially noticed FDA device approval establishes its intended uses; plaintiff’s claim of off-label promotion is dismissed because it concerned a labeled use); Brock v. City of Bellingham, 2025 WL 254725, at *5 (W.D. Wash. Jan. 21, 2025) (judicially noticing FDA COVID vaccine emergency use approvals; “[g]iven the judicially noticeable facts . . ., the Court concludes that the . . . vaccine available to Plaintiffs was not an ‘investigational drug’ at any time relevant to Plaintiffs’ claims”); Argueta v. Walgreens Co., 760 F. Supp.3d 1028, 1038 (E.D. Cal. 2024) (complaint dismissed where court took judicial notice that the defendant’s product “is indeed a drug approved for the treatment” of the relevant condition); Curtis v. PeaceHealth, 2024 WL 248719, at *2 (W.D. Wash. Jan. 23, 2024) (same as prior Curtis holding), aff’d, 154 F.4th 678 (9th Cir. 2025); Curtis v. Inslee, 709 F. Supp.3d 1257, 1265 (W.D. Wash. 2023) (The COVID vaccine’s status “is accurately and readily determined from the FDA’s approval and CDC’s explanation,” which “are sources whose accuracy cannot be reasonably questioned”), aff’d, 154 F.4th 678 (9th Cir. 2025); Leake v. Raytheon Technologies Corp., 2023 WL 2242857, at *1 n.2 (D. Ariz. Feb. 27, 2023) (judicially noticed FDA information established that allegation of a product recall was “demonstrably false”), aff’d, 2024 WL 1854287 (9th Cir. April 29, 2024); Morris v. Sun Pharma Global, Inc., 2021 WL 3913191, at *3 (C.D. Cal. May 13, 2021) (allegation that defendant was a drug “manufacturer” contradicted by judicially noticed FDA document listing defendant as a “distributor”; “[a]ll of Plaintiff’s allegations based on negligence relate to the manufacturing, not the distribution, of [the drug]”, so “Plaintiff fails to state a negligence claim”); Gioia v. Janssen Pharmaceuticals, 2021 WL 602683, at *4 (E.D.N.Y. Feb. 16, 2021) (judicial notice taken of drug labeling; “plaintiff’s conclusory allegations coupled with plaintiff’s allegations of suffering from the very side effects of which defendant warns, require dismissal of plaintiff’s claim”); Dye v. Covidien LP, 470 F. Supp.3d 1329, 1341 (S.D. Fla. 2020) (judicial notice taken of FDA-approved device instructions for use; “[c]learly, the IFU contradicts all of Plaintiff’s allegations”); Marroquin v. Pfizer, Inc., 367 F. Supp.3d 1152, 1163 & n.5 (E.D. Cal. 2019) (warning claims dismissed as inconsistent with judicially noticed drug label); Lifeway Foods, Inc. v. Millenium Products, Inc., 2016 WL 7336721, at *2 (C.D. Cal. Dec. 14, 2016) (non-prescription medical product case; judicially noticed FDA letters; “this Court . . . will not blindly accept allegations which are directly contradicted by evidence subject to judicial notice”); Porter v. Wetzel, 2012 WL 4442792, at *5 (Mag. W.D. Pa. Aug. 24, 2012) (judicial notice of FDA approval established that, contrary to the complaint, plaintiff received appropriate medical care), adopted, 2012 WL 4378116 (W.D. Pa. Sept. 25, 2012); In re Bayer Corp. Combination Aspirin Products Marketing & Sales Practices Litigation, 701 F. Supp.2d 356, 367-68 (E.D.N.Y. 2010) (allegations contrary to judicially noticed FDA documents disregarded; “[a]lthough . . . a motion to dismiss . . . tak[es] all the allegations as true . . ., the court is not required to reason in a vacuum”).
As our earlier post demonstrated, many types of FDA materials have properly been the subject of judicial notice. To the extent that a complaint makes factually false allegations that defense counsel can refute by judicially noticeable FDA documents, these allegations can be disregarded for purposes of otherwise pleadings-based motions under Rule 12. Successfully doing so can be of great value to our clients, which are thereby spared the expense and bother of discovery that waiting for summary judgment would otherwise require.
