SPENCER, Case No.: 1:21-cv-01551-JLT-CDB 12 Plaintiff, FINDINGS AND RECOMMENDATIONS TO GRANT IN PART AND DENY IN PART 13 v. PLAINTIFF’S MOTION TO STRIKE AFFIRMATIVE DEFENSES 14 STUART SHERMAN, et al., (Doc. 33) 15 Defendants. 14-DAY OBJECTION PERIOD 16
17 Plaintiff Edward B. Spencer is proceeding pro se and in forma pauperis in this civil rights 18 action pursuant to 42 U.S.C. section 1983. This action proceeds on Plaintiff’s Eighth Amendment 19 failure to protect claim against Defendant Lopez. 20 I. RELEVANT BACKGROUND 21 This action presently is proceeding through the Court’s discovery and pretrial motion 22 schedule. (Doc. 31) On October 6, 2025, Plaintiff filed a “Motion to Strike Defendant Affirmative 23 Defenses to Complaint.” (Doc. 33.) Defendant Lopez opposed the motion (Doc. 35), and Plaintiff 24 replied (Doc. 36). 25 II. LEGAL STANDARDS 26 Federal Rule of Civil Procedure 8(c) requires the responding party to “affirmatively state 27 any avoidance or affirmative defense” and then provides a nonexhaustive list of affirmative 1 v. Bock, 549 U.S. 199, 212 (2007) (finding list “nonexhaustive”). An affirmative defense is an 2 assertion of facts that if proven would defeat or reduce the stated claim. Thus, allegations that 3 merely claim the plaintiff cannot meet his burden of proof or merely reserves the right to identify 4 future defenses is not a proper affirmative defense. See Zivkovic v. So. Cal. Edison Co., 302 F.3d 5 1080, 1088 (9th Cir. 2002). 6 Pursuant to Federal Rule of Civil Procedure 12(f), the Court may strike from an answer 7 “an insufficient defense or any redundant, immaterial, impertinent, or scandalous matter.” Fed. R. 8 Civ. P. 12(f). An affirmative defense may be insufficient either “as a matter of pleading or as a 9 matter of law.” Harris v. Chipotle Mexican Grill, Inc., 303 F.R.D. 625, 627-28 (E.D. Cal. 2014) 10 (citing Dodson v. Strategic Restaurants Acquisition Co., 289 F.R.D. 595, 603 (E.D. Cal. 2013)). 11 “Legal insufficiency means that the affirmative defense lacks merit ‘under any set of facts the 12 defendant might allege.’ Pleading insufficiency means a failure to provide the plaintiff with fair 13 notice.” Dodson, 289 at F.R.D. at 603 (internal citations omitted). An affirmative defense must 14 give fair notice of the defense pled. Wyshak v. City Nat’l Bank, 607 F.2d 824, 826 (9th Cir. 15 1979). 16 “In Kohler v. Flava Enterprises, Inc., the Ninth Circuit continued to apply the ‘fair notice’ 17 standard to affirmative defenses.” Chock v. Stryker Corp., No. 1:21-cv-00996-KES-CDB, 2025 18 WL 1797933, at *1 (E.D. Cal. June 30, 2025) (citing Kohler v. Flava Enterprises, Inc., 779 F.3d 19 1016, 1019 (9th Cir. 2015)) (“[T]he ‘fair notice’ required by the pleading standards only requires 20 describing the defense in ‘general terms.’”).1 While Kohler did not address any tension with 21 Twombly and Iqbal’s “plausible on its face” standard for complaints,2 courts in this district have 22 interpreted Kohler as reflecting that Wyshak’s “fair notice” standard continues to apply to 23 affirmative defenses.3 See id. (citing Gomez v. J. Jacobo Farm Lab. Contractor, Inc., 188 F. 24 1 More recently, the Ninth Circuit endorsed the continuing applicability of the “fair notice” standard to 25 affirmative defenses. See Garcia v. Salvation Army, 918 F.3d 997, 1008 (9th Cir. 2019) (citing Wyshak, 607 F.2d at 827). 26 2 See Bell Atlantic Corp. v. Twombly, 550 U.S. 544 (2007) and Ashcroft v. Iqbal, 556 U.S. 662 (2009), 27 establishing a “plausible on its face” standard as to allegations of a complaint.
3 1 Supp. 3d 986, 991–92 (E.D. Cal. 2016) (collecting cases)). 2 “An affirmative defense is adequately pled if it gives the opposing party ‘fair notice of the 3 defense’ such that the other party may rebut the defense or strategize accordingly.” Gen. 4 Convention of New Jerusalem in United States of America v. Calamigos Ranch Corp., No. 2:23- 5 cv-00572-HDV-MAR, 2023 WL 6192704, at *2 (C.D. Cal. Aug. 10, 2023) (citing Simmons v. 6 Navajo Cnty., Ariz., 609 F.3d 1011, 1023 (9th Cir. 2010) (quoting Wyshak, 607 F.2d at 827) 7 (overruled on other grounds by Castro v. Cnty. of Los Angeles, 833 F.3d 1060 (9th Cir. 2016)). 8 Although the “fair notice” standard is relatively low, it imposes a requirement that there be “some 9 valid factual basis” pleaded in support of the affirmative defense. Rosen v. Masterpiece Mkgt. 10 Grp., 222 F. Supp.3d 793, 798 (C.D. Cal. 2016) (citations omitted). 11 III. DISCUSSION 12 Plaintiff’s Motion to Strike Affirmative Defenses 13 Plaintiff contends Defendant’s affirmative defenses “are boilerplating listing of 14 Affirmative Defenses,” irrelevant to his claims. He argues Defendant fails to allege sufficient and 15 “identifiable” facts, alleging only conclusory statements. Further, Plaintiff contends Defendant’s 16 affirmative defenses are “vague, conclusory allegations that fail.” Plaintiff maintains this Court 17 “should apply the pleading standard set forth in Wyshak … to determine whether a Defendant has 18 provided fair notice of an affirmative defense.” 19 Defendant’s Opposition 20 First, Defendant contends Plaintiff’s motion is untimely by more than 30 days and should 21 be denied on that basis. Second, Defendant maintains the affirmative defenses meet the required 22 pleading standard and should not be stricken. Next, Defendant asserts the pleading standard set 23 forth in Wyshak and relied upon by Plaintiff supports Defendant’s affirmative defenses. Further, 24
25 or the Twombly/Iqbal standard applies to the pleading of affirmative defenses. Cf. Cota v. Avenda Corp., No. 3:20- cv-01137-BEN-BGS, 2020 WL 6083423, at *3-4 (S.D. Cal. Oct. 14, 2020) (collecting cases and noting “[t]he 26 Southern District follows the Ninth Circuit’s decision in Kohler”) with United States v. Academy Mortgage Corp., No. 16-cv-02120-EMC, 2020 WL 7056017, at *2 (N.D. Cal. Dec. 2, 2020) (collecting cases and noting “[o]nly two 27 courts in this district have applied the lower ‘general terms’ standard from Kohler,” and concluding “[t]here are strong policy reasons for requiring parties to meet the pleading standard set forth in Twombly and Iqbal for 1 Defendant contends Plaintiff “is also on fair notice of these defenses due to his extensive history 2 litigating cases in which similar defenses were asserted” and that it is “implausible to think that 3 Spencer does not have notice or knowledge of” the affirmative defenses asserted here. Defendant 4 maintains Plaintiff does not argue the affirmative defenses are insufficient, redundant, immaterial, 5 impertinent, or scandalous. Even so, if the Court finds otherwise, because there is no prejudice to 6 Plaintiff, Defendant should be granted leave to file an amended answer.

DISCUSSION 12 Plaintiff’s Motion to Strike Affirmative Defenses 13 Plaintiff contends Defendant’s affirmative defenses “are boilerplating listing of 14 Affirmative Defenses,” irrelevant to his claims. He argues Defendant fails to allege sufficient and 15 “identifiable” facts, alleging only conclusory statements. Further, Plaintiff contends Defendant’s 16 affirmative defenses are “vague, conclusory allegations that fail.” Plaintiff maintains this Court 17 “should apply the pleading standard set forth in Wyshak … to determine whether a Defendant has 18 provided fair notice of an affirmative defense.” 19 Defendant’s Opposition 20 First, Defendant contends Plaintiff’s motion is untimely by more than 30 days and should 21 be denied on that basis. Second, Defendant maintains the affirmative defenses meet the required 22 pleading standard and should not be stricken. Next, Defendant asserts the pleading standard set 23 forth in Wyshak and relied upon by Plaintiff supports Defendant’s affirmative defenses. Further, 24
25 or the Twombly/Iqbal standard applies to the pleading of affirmative defenses. Cf. Cota v. Avenda Corp., No. 3:20- cv-01137-BEN-BGS, 2020 WL 6083423, at *3-4 (S.D. Cal. Oct. 14, 2020) (collecting cases and noting “[t]he 26 Southern District follows the Ninth Circuit’s decision in Kohler”) with United States v. Academy Mortgage Corp., No. 16-cv-02120-EMC, 2020 WL 7056017, at *2 (N.D. Cal. Dec. 2, 2020) (collecting cases and noting “[o]nly two 27 courts in this district have applied the lower ‘general terms’ standard from Kohler,” and concluding “[t]here are strong policy reasons for requiring parties to meet the pleading standard set forth in Twombly and Iqbal for 1 Defendant contends Plaintiff “is also on fair notice of these defenses due to his extensive history 2 litigating cases in which similar defenses were asserted” and that it is “implausible to think that 3 Spencer does not have notice or knowledge of” the affirmative defenses asserted here. Defendant 4 maintains Plaintiff does not argue the affirmative defenses are insufficient, redundant, immaterial, 5 impertinent, or scandalous. Even so, if the Court finds otherwise, because there is no prejudice to 6 Plaintiff, Defendant should be granted leave to file an amended answer. 7 Plaintiff’s Reply 8 First, Plaintiff contends his motion is timely because the Court did not lift the previously 9 imposed 120-day stay of these proceedings until September 18, 2025, meaning his October 6, 10 2025, motion was filed within the 21 days set by Rule 12(f). Next, Plaintiff argues “Defendant’s 11 shotgun answer, without any underlying supporting facts, contains many potentially spurious 12 issues” and asserts the answer offers “no facts whatsoever.” More specifically, Plaintiff asserts 13 “Defendant’s First, Second, Third, Fourth, and Fifth affirmative defenses do not give Plaintiff 14 sufficient notice to allow him to prepare his case.” Further, Plaintiff maintains that “Defendant 15 wants to insert res judicata defense because Spencer asserted similar claims in a case against the 16 same Defendant,” but the two actions do not involve “the same transactional nucleus of facts” or 17 the “same subject matter so there is no res judicata defense.” Plaintiff asks the Court to grant him 18 motion “because it was timely and because the affirmative defenses were not properly pleaded.” 19 The Affirmative Defenses 20 Defendant filed an answer to Plaintiff’s operative first amended complaint on August 12, 21 2025, asserting the following affirmative defenses: 22 First Affirmative Defense 23 At all relevant times, Defendant acted within the scope of discretion, with due care, and with good faith in fulfillment of Defendant’s 24 responsibilities under all applicable statutes, rules, regulations, and practices; within the bounds of reason under all circumstances 25 known, and with the good-faith belief that his actions comported with all applicable federal and state laws. Defendant[] therefore assert[s] 26 that Plaintiff’s claim is barred, limited, or controlled by principles of immunity, including the federal-law principle of qualified immunity. 27 /// 1 Second Affirmative Defense 2 To the extent Plaintiff asserts he suffered harm or injuries, Plaintiff failed to take reasonable steps to mitigate the harm or injuries. 3 Third Affirmative Defense 4 Plaintiff has failed to exhaust administrative remedies as required by 5 the Prison Litigation Reform Act, 42 U.S.C. § 1997e(a), and his claims are therefore barred. 6 Fourth Affirmative Defense 7 Defendant did not act with malicious intent or with reckless disregard 8 for Plaintiff’s rights and therefore is not liable for punitive damages. 9 Fifth Affirmative Defense Plaintiff’s claims are barred by the doctrine of res judicata. 10 11 (Doc. 26 at 6-7.) 12 Analysis 13 The Court finds Plaintiff’s motion is timely. As reflected on the docket, Defendant 14 answered the complaint on August 12, 2025, and the Court issued its order regarding early ADR 15 the following day. (Docs. 26 & 27.) The order expressly states: “No pleadings or motion may be 16 filed in this case during the [120-day] stay.” (Doc. 27 at 2.) Therefore, Plaintiff could not file the 17 instant motion until the stay was lifted on September 18, 2025. (Doc. 30.) 18 days later,4 Plaintiff 18 filed his motion, making it timely pursuant to Rule 12(f). 19 First Affirmative Defense 20 This defense alleges Defendant acted “within the scope of discretion, with due care, and 21 with good faith ….” The undersigned finds the first affirmative defense puts Plaintiff on fair 22 notice that Defendant Lopez will argue the alleged wrongful conduct constituted an exercise of 23 discretion, carried out with due care and in good faith. See Roe v. City of San Diego, 289 F.R.D. 24 604, 609 (S.D. Cal. 2013) (“ample case law describes the scope of these defenses, and at this 25 point in the litigation, the Individual Defendants need not elaborate further”); Kaur v. City of 26 Lodi, No. 2:14-cv-00828-TLN-AC, 2016 WL 627308, at *3 (E.D. Cal. Feb. 17, 2016) (denying 27 4 Plaintiff’s motion is dated and signed August 20, 2025. (Doc. 33 at 1, 5.) And despite an attached Proof of Service 1 motion to strike good faith affirmative defense and noting federal courts’ reluctance “to determine 2 disputed or substantial issues of law [such as a discretionary versus non-discretionary functions] 3 on a motion to strike”). 4 Further, it is well established that qualified immunity is an affirmative defense, and one 5 that does not require additional facts to be sufficiently plead. Crawford-El v. Britton, 523 U.S. 6 574, 587 (1998); L.F. v. City of Stockton, No. 2:17-cv-01648-KJM-DB, 2018 WL 3817558, at *7 7 (E.D. Cal. Aug. 9, 2018) (stating that “qualified immunity is sufficiently pleaded without 8 additional factual bases”) (citing Kaur, 2016 WL 627308, at *3). The assertion of this affirmative 9 defense puts Plaintiff on notice that Defendant intends to argue that the alleged wrongful conduct 10 constituted an exercise of discretion and was carried out in good faith. Further, the undersigned 11 finds that a motion to strike “is not a good fit for resolving issues like [q]ualified [i]mmunity 12 which often turn on facts yet to be developed.” Atkins v. Pickard, 298 F. App'x 512, 513 (7th Cir. 13 2008); Mollica v. Cnty. of Sacramento, No. 2:19-CV-02017-KJM-DB, 2021 WL 2853863, at *2 14 (E.D. Cal. July 8, 2021) (“This defense gives adequate notice of the individual defendants’ intent 15 to argue they are entitled to qualified immunity against claims under § 1983, a commonly 16 litigated and well-understood affirmative defense”). Thus, the Court will recommend Plaintiff's 17 motion to strike the first affirmative defense be denied. 18 Second Affirmative Defense 19 “A failure to mitigate generally arises when an injured party could have prevented the 20 continuation or enhancement of the injury.” Baker v. Shahbazian, No. 1:24-CV-01279-HBK, 21 2025 WL 3224932, at *3 (E.D. Cal. Nov. 19, 2025) (citation and quotation omitted). While a 22 failure to mitigate is an affirmative defense, here, it is conclusory and devoid of factual support. 23 The undersigned recognizes that affirmative defenses ordinarily require little to no factual 24 support. Wyshak, 607 F.2d at 827. Nonetheless, there are various ways a plaintiff fails to mitigate 25 damages, and the Court presumes Defendant possesses facts suggesting a failure to mitigate. A 26 brief description of that factual basis should be included so that this defense is not “fact barren.” 27 Gomez, 188 F.Supp.2d at 992. Because the affirmative defense fails to give any indication as to 1 Rest., L.P., No. 2:20-cv-2620-VAP-Ex, 2020 WL 4035071, at *15 (C.D. Cal. July 16, 2020) 2 (striking a failure to mitigate affirmative defense because no factual basis of any kind was pled); 3 cf. Kaur, 2016 WL 627308, at *5 (ruling that defendants properly asserted an affirmative defense 4 for plaintiff's failure to mitigate damages because defendants explained in their affirmative 5 defense that plaintiff failed to mitigate emotional damages because she did not seek counseling); 6 Gomez, 188 F.Supp.3d at 1003 (striking without prejudice an inapplicable mitigation defense but 7 requiring any amendment to explain the factual and legal basis for the mitigation defense). 8 Because the second affirmative defense is insufficiently pled, the Court will recommend granting 9 Plaintiff's motion to strike the second affirmative defense but also to grant Defendant leave to 10 amend the answer to provide some factual basis to support the defense. 11 Third Affirmative Defense 12 Failure to exhaust is a proper affirmative defense. Albino v. Baca, 747 F.3d 1162 (9th Cir. 13 2014) (en banc). Courts generally have agreed that a failure to exhaust is a well-known 14 affirmative defense that provides fair notice even in the absence of a detailed factual basis. See, 15 e.g., Francis v. Luna, No. 2:24-cv-03740-MRA-SSC, 2024 WL 5182198, at *6 (C.D. Cal. Oct. 16 25, 2024) (denying motion to strike PLRA affirmative defense as conclusory, noting: “Like 17 qualified immunity, the PLRA is frequently litigated, well established, and easily understood”); 18 Schmitz v. Asman, No. 2:20-cv-00195-JAM-CKD PS, 2022 WL 2340614, at *26 (E.D. Cal. June 19 29, 2022) (“raising failure to exhaust administrative remedies under the [PLRA] provides fair 20 notice by its bare assertion”); Antonio v. Kokor, No. 1:16-cv-00716-DAD-MJS (PC), 2017 WL 21 942386, at *3 (E.D. Cal. Mar. 10, 2017) (“Defense No. 2 alleges that Plaintiff failed to exhaust 22 his administrative remedies as required by the Prison Litigation Reform Act and gives Plaintiff 23 reasonable notice that exhaustion is in issue”). Accordingly, the undersigned will recommend that 24 Plaintiff’s motion be denied as to the third affirmative defense. 25 Fourth Affirmative Defense 26 An assertion that “Defendant did not act with malicious intent or with reckless disregard 27 for Plaintiff’s rights and therefore is not liable for punitive damages” seeks to negate an element 1 289 F.R.D. at 610 (“Defendants’ denial of punitive damages is not an affirmative defense, but is 2 rather an assertion that Plaintiff has not proved essential elements of her claim,” citing Zivkovic, 3 302 F.3d at 1088); Baker, 2025 WL 3224932, at *3 (same and striking without leave to amend); 4 Williams v. Hill, No. 2:23-cv-00958 TLN SCR P, 2025 WL 2448344, at *4 (E.D. Cal. Aug. 26, 5 2025) (“Here, defendants’ denial of liability for damages goes to the substance of plaintiff's case 6 and is not an affirmative defense. Accordingly, plaintiff's motion to strike this defense should be 7 granted without leave to amend”); Kaur, 2016 WL 627307, at *3 (striking similar affirmative 8 defense without leave to amend). Accordingly, the undersigned will recommend Plaintiff’s 9 motion to strike the fourth affirmative defense be granted, without leave to amend. 10 Fifth Affirmative Defense 11 Fair notice is a “low” bar and does not require “great detail,” but it does require “some 12 factual basis for its affirmative defense.” Gomez, 188 F.Supp.3d at 992; Baker, 2025 WL 13 3224932, at *4 (“Because Defendant fails to provide the basic information establishing the 14 grounds for the affirmative defense of collateral estoppel or res judicata, he does not provide fair 15 notice to Plaintiff”); see G & G Closed Circuit Events, LLC v. Nguyen, No. 10-CV-00168-LHK, 16 2010 WL 3749284, at *2 (N.D. Cal. Sept. 23, 2010) (striking affirmative defenses— unclean 17 hands, res judicata, collateral estoppel, and superseding events—for failure to provide “basic 18 information” necessary for fair notice to plaintiff). Because the answer fails to provide sufficient 19 information establishing the grounds for the affirmative defense of res judicata, Defendant does 20 not provide fair notice to Plaintiff. Therefore, the Court will recommend granting Plaintiff's 21 motion to strike the fifth affirmative defense but also to grant Defendant leave to amend the 22 answer to provide some factual basis for this defense. 23 Defendant’s Argument Concerning Plaintiff’s Litigation History 24 The undersigned elects not to address Defendant’s argument that Plaintiff had fair notice 25 of the affirmative defenses “due to his extensive history litigating cases in which similar defenses 26 were asserted.” The Court is skeptical that a plaintiff’s litigation history, even an extensive one, 27 can serve to provide fair notice of a defendant’s affirmative defenses in subsequent actions filed 1 IV. CONCLUSION AND RECOMMENDATIONS 2 Based upon the foregoing, this Court HEREBY RECOMMENDS as follows: 3 1. Plaintiff's motion to strike be GRANTED as to the second and fifth affirmative 4 defenses, with leave to amend; 5 2. Plaintiffs motion to strike be GRANTED as to the fourth affirmative defense, 6 without leave to amend; 7 3. Plaintiffs motion to strike be DENIED as to the first and third affirmative defenses; 8 and 9 4.
