IN THE UNITED STATES DISTRICT COURT 

FOR THE NORTHERN DISTRICT OF ILLINOIS 

EASTERN DIVISION 

SHARON LYONS et al., 

 Plaintiffs, 

 v. 

CITY OF CHICAGO et al., 

 Defendants. 

 No. 20-cv-03412 

 Judge John F. Kness 

 

MEMORANDUM OPINION & ORDER 

Presently before the Court is Defendant City of Chicago’s motion to bifurcate 

Minor-Plaintiff L.S.’s Monell claim against the City from the remaining claims 

against the Chicago Police Department Officers and stay discovery and trial on the 

Monell claim pending resolution of the claims against the Defendant Officers. (Dkt. 

96.) For the following reasons, Defendant City’s motion to bifurcate and stay 

discovery and trial on the Monell claim is granted. 

I. BACKGROUND 

Plaintiffs Sharon Lyons, Julius Terry, and L.S., a minor child represented by 

Lyons, brought this lawsuit against the City of Chicago and twelve Chicago Police 

Department officers for claims arising out of an allegedly unlawful execution of a 

drug-related search warrant. (Dkt. 27.) On February 26, 2020, Defendant Officer 

Hammermeister obtained two search warrants authorizing a search for cocaine and 

heroin in the first and second floor apartments at 4937 South Justice Avenue. 

Case: 1:20-cv-03412 Document #: 126 Filed: 03/07/23 Page 1 of 12 PageID #:3117

(Id. ¶ 37.) The search warrants were based on information from a confidential 

informant that an individual named “Blondie” was selling drugs out of the 

apartments. (Id. ¶ 38.) That night, approximately eleven Defendant Officers executed 

the search warrant at the second-floor apartment where Lyons and Terry resided. 

(Id. ¶¶ 2–3, 16–17.) The officers entered through the front door with their guns drawn 

and performed a sweep of the apartment, including in Lyons’s bedroom where L.S. 

was napping. (Id. ¶¶ 18, 52–56, 58.) Multiple officers entered the bedroom and 

pointed their guns at L.S. before bringing her to Lyons in the kitchen. (Id. ¶¶ 63, 68.) 

Defendant Officers then completed a search of the apartment but did not discover any 

drugs or Blondie, and no arrests were made. (Id. ¶¶ 74–75.) 

On September 18, 2020, Plaintiffs filed their Amended Complaint alleging 

claims against Defendant Officers under 42 U.S.C. § 1983 for violations of the Fourth 

and Fourteenth Amendments and various state law claims (Counts II through IX). 

(Id. at 30–40.) In addition, L.S. brought a Monell claim against the City alleging that 

certain policies, practices, and/or customs of the City caused her constitutional 

injuries. (Id. ¶¶ 103–134.). Specifically, L.S., who is black, claims that the Defendant 

Officers’ conduct, including pointing guns at L.S., was undertaken pursuant to the 

City’s widespread pattern and practice or de facto policy of excessive force against 

and/or in the presence of children of color, which proximately caused the violation of 

her Fourth and Fourteenth Amendment rights. (Id. ¶¶ 104, 125, 130.) 

Defendant City moved to bifurcate for trial Plaintiffs’ claims against the 

Defendant Officers from L.S.’s Monell claim against the City and stay discovery and 

Case: 1:20-cv-03412 Document #: 126 Filed: 03/07/23 Page 2 of 12 PageID #:3118

trial on the Monell claim. (Dkt. 96.) Plaintiffs oppose Defendant City’s motion to 

bifurcate. (Dkt. 104.) On January 9, 2023, the Court held oral argument on the 

motion. (Dkt. 114.) 

II. LEGAL STANDARD 

Rule 42(b) of the Federal Rules of Civil Procedure governs bifurcation of claims. 

“For convenience, to avoid prejudice, or to expedite and economize, the court may 

order a separate trial of one or more separate issues, claims, crossclaims, 

counterclaims, or third-party claims.” Fed. R. Civ. P. 42(b). As the Seventh Circuit 

has held, if even “one of these criteria is met, the district court may order bifurcation 

as long as doing so will not prejudice the non-moving party or violate the Seventh 

Amendment.” Chlopek v. Federal Ins. Co., 499 F.3d 692, 700 (7th Cir. 2007); see also 

Houseman v. U.S. Aviation Underwriters, 171 F.3d 1117, 1121 (7th Cir. 1999) (Courts 

“must be satisfied that the decision to bifurcate does not unfairly prejudice the 

non-moving party.”). Whether to bifurcate claims is “committed to the discretion of 

the district court” and “made on a case by case basis.” Real v. Bunn-O-Matic Corp., 

195 F.R.D. 618, 620 (N.D. Ill. 2000). 

III. DISCUSSION 

A. The Parties’ Arguments 

Defendant City first asserts that bifurcation will prevent prejudice to all 

Defendants. (Dkt. 96 at 11–13.) Defendant Officers say they would be prejudiced by 

a joint trial because “[i]ntroducing evidence relating to [L.S.]’s Monell claim . . . 

invites jurors to find the individual defendant officers guilty by association, rather 

Case: 1:20-cv-03412 Document #: 126 Filed: 03/07/23 Page 3 of 12 PageID #:3119
4

than deciding liability based on their own actions.” (Id. at 11–12.); see Lopez v. City 

of Chicago, 2002 WL 335346, at *2 (N.D. Ill. Mar. 1, 2002) (“Without bifurcation, the 

jury would likely hear evidence against the City of Chicago’s various acts of alleged 

police misconduct committed by numerous non-party officers to establish a policy or 

practice. Such evidence can be prejudicial to the individual defendants.”). Bifurcation 

would also avoid substantial prejudice to the City because, the City urges, if “the 

allegations against the [Defendant Officers] are proven at trial, the jury may hold the 

City liable on the Monell claim merely because it is appalled by the officers’ conduct, 

thereby improperly converting the Monell claim into a respondeat superior claim.” 

(Dkt. 96 at 12.); see Bradford v. City of Chicago, 2019 WL 5208852, at *4 (N.D. Ill. 

Oct. 16, 2019) (Bifurcation is appropriate because of the risk that “Monell would 

devolve into a respondeat superior claim.”). Prejudice to the Plaintiffs will also be 

prevented because bifurcation will lead to earlier disposition of Plaintiffs’ individual 

claims. (Dkt. 96 at 13.); see Clarett v. Suroviak, 2011 WL 37838, at *2 (N.D. Ill. Jan. 

3, 2021) (Earlier disposition of individual claims is likely because “bifurcation allows 

a bypass of discovery relating to the Monell claims, which can add significant . . . 

time, effort, [and] cost.”). 

Defendant City further argues that bifurcation promotes judicial economy 

because, generally, a plaintiff cannot prevail on a Monell claim without first 

establishing an underlying constitutional violation by an officer. (Dkt. 96 at 8.) 

Applying that rule, Defendant City says that if L.S. is “unsuccessful in [her] claim[] 

against the individual defendants, [she] will no longer have a cause of action against 

Case: 1:20-cv-03412 Document #: 126 Filed: 03/07/23 Page 4 of 12 PageID #:3120
5

the city.” City of Los Angeles v. Heller, 475 U.S. 796, 799 (1986); see also First Midwest 

Bank v. City of Chicago, 988 F.3d 978, 987 (7th Cir. 2021) (“A Monell plaintiff must 

establish that he suffered a deprivation of a federal right before municipal fault, 

deliberate indifference and causation come into play.”). Consequently, any Monell 

discovery—which the City contends is extensive—should not commence before 

Defendant Officers are found liable. (Id. at 8–11.) 

Finally, Defendant City notes that, “if any Defendant Officers are found liable 

for a constitutional violation, the City will consent to entry of judgment against it for 

the damages caused by the violation and reasonable attorney fees without requiring 

Plaintiff to prove § 1983 municipal liability . . . thereby avoiding litigation of the 

Monell claim altogether.” (Id. at 13–14.) Litigation of L.S.’s Monell claim and the 

corresponding discovery is thus unnecessary. 

Plaintiffs disagree with Defendant City’s prejudice and efficiency arguments. 

Plaintiffs contend that the balance of prejudice weighs against bifurcation because 

any so-called “Monell evidence” is likely to be “admissible against the Officers even if 

there were no Monell claim,” and likewise, “a large portion of evidence of Officers’ 

individual liability . . . will be admissible against the City on [L.S.]’s Monell claim.” 

(Dkt. 104 at 13–14.) Furthermore, it is “wholly premature and speculative” at this 

stage “to predict the evidence that the parties might offer at trial and to weigh the 

potential prejudice posed by that evidence.” (Id. at 14.) Regardless, Plaintiffs argue 

that any prejudice to the Defendants at trial can be managed by motions in limine

and limiting instructions. (Id.); see Mendez v. City of Chicago, 2020 WL 1479081, at 

Case: 1:20-cv-03412 Document #: 126 Filed: 03/07/23 Page 5 of 12 PageID #:3121

*5 (N.D. Ill. Mar. 26, 2020) (“The best way to stave off Defendants’ prejudice concern 

is to use motions in limine and limiting instructions at trial to make sure the jury 

understands the distinctions between the claims against the Defendant Officers and 

the City.”). If anything, Plaintiffs say L.S. would be prejudiced because “bifurcation 

would both delay final resolution of her Monell claim and drive up the cost of litigating 

that claim.” (Dkt. 104 at 15.) 

Plaintiffs also contend that bifurcation would not promote efficiency. Plaintiffs 

assert that L.S. is not required to prevail against Defendant Officers to prevail on her 

Monell claim because Thomas v. Cook County Sheriff’s Department created an 

exception to the general rule that municipal liability is contingent upon officer 

liability. 604 F.3d 293, 305 (7th Cir. 2009). In Thomas, the Seventh Circuit explained 

that “a municipality can be held liable under Monell even when its officers are not 

unless such a finding would create an inconsistent verdict.” Id.; see also Swanigan v. 

City of Chicago, 775 F.3d 953, 962 (7th Cir. 2015) (A “verdict in favor of individual 

defendants would not necessarily be inconsistent with a plaintiff’s verdict on a 

factually distinct Monell claim.”). Applying Thomas, Plaintiffs argue that “the City’s 

liability does not depend on the Officers’ liability because [L.S.]’s Monell claim is 

predicated on a Fourth Amendment excessive force violation and Plaintiffs have not 

brought a Fourth Amendment excessive force claim against the Officers.” (Dkt. 104 

at 6.) This means that even if “Plaintiffs were to lose on all of their claims against the 

Officers, that would not necessarily preclude [L.S.] from pursuing her Monell claim 

against the City.” (Id. at 6–7.) Moreover, the majority of relevant discovery—five of 

Case: 1:20-cv-03412 Document #: 126 Filed: 03/07/23 Page 6 of 12 PageID #:3122
7

the six years in the Monell period—has already been prepared by the City in 

responding to two nearly identical cases in the Northern District of Illinois. (Id. at 7–

8.) See Mendez, 2020 WL 1479081; Tate v. City of Chicago, 2019 WL 2173802 (N.D. 

Ill. May 20, 2019). So, any additional Monell discovery is minimal and should not be 

delayed. 

Finally, Plaintiffs say Defendant City’s proposed consent to entry of judgment 

does not alleviate the need for a Monell trial. Relying on Swanigan, 775 F.3d at 959–

62, Plaintiffs say the proposal is procedurally improper because it is not an offer of 

judgment under Rule 68 of the Federal Rules of Civil Procedure, as it does not provide 

L.S. with the non-economic relief she seeks, namely, a judgment that holds Defendant 

City publicly “accountable for systemic practices that cause constitutional harm” and 

“deter[s] future misconduct.” (Dkt. 104 at 15–16.) Nor is the proposed consent a 

stipulation under Rule 16 of the Federal Rules of Civil Procedure “because it does not 

stipulate to any facts and because Plaintiff emphatically rejects it.” (Id. at 16.) 

B. Analysis: Bifurcation is Warranted

A district court has broad discretion to bifurcate claims for trial. Real, 195 

F.R.D. at 620 (whether to bifurcate claims is “committed to the discretion of the 

district court” and “made on a case by case basis”). For the following reasons, the 

Court bifurcates Plaintiffs’ Monell claim for discovery and trial. 

First, the risk of unfair prejudice to Defendants justifies bifurcation. Plaintiffs 

seek to prove that Defendant City’s de facto policy of using excessive force against 

and/or in the presence of children of color caused L.S.’s constitutional injury. To 

Case: 1:20-cv-03412 Document #: 126 Filed: 03/07/23 Page 7 of 12 PageID #:3123
8

support this claim, Plaintiffs seek discovery on all allegations against Chicago police 

officers from 2014 to 2020 of illegal searches in which a child was present for the 

search and some forced was used. (Dkt. 96 at 4–5; Dkt. 104 at 7–8.) When presented 

with six years of excessive force complaints against other children, it is possible, 

perhaps probable, that a jury would, by association, impermissibly hold the 

Defendant Officers accountable by association. Bradford, 2019 WL 5208852, at *3 

(Bifurcation warranted because introducing six years of evidence concerning 

violations by other city officials is “wholly unrelated to the Individual Defendants’ 

conduct on the single day at issue in the case against them.”). Plaintiffs contend 

bifurcation would not alleviate this risk of prejudice because “a large portion of the 

so-called Monell evidence” would be admissible against Defendant Officers even if 

there were no Monell claim. (Dkt. 104 at 13–14.) Plaintiffs, however, fail to explain 

how department-wide allegations of excessive force against children will be 

admissible against the individual Defendant Officers, who are accused of violating 

the rights of L.S during a single search. 

Moreover, bifurcation prevents prejudice to Defendant City. Plaintiffs assert a 

respondeat superior claim against the Defendant Officers. This means that the jury 

must assess evidence regarding the individual Officers’ misconduct and City policy, 

which risks that “Monell would devolve into a respondeat superior claim.” Bradford, 

2019 WL 5208852, at *4; Milestone v. City of Monroe, Wis., 665 F.3d 774, 780 (7th Cir. 

2011) (“There is no respondeat superior liability under § 1983; the Supreme Court 

‘distinguish[es] acts of the municipality from acts of employees of the municipality.’ ” 

Case: 1:20-cv-03412 Document #: 126 Filed: 03/07/23 Page 8 of 12 PageID #:3124
9

(quoting Pembaur v. City of Cincinnati, 475 U.S. 469, 479 (1986))). Bifurcation avoids 

this risk entirely. 

Plaintiffs contend that any risk of prejudice can be ameliorated through 

motions in limine and limiting instructions. Although it is undisputed that “limiting 

instructions are taken very seriously in this Circuit as a tool for reducing or 

eliminating prejudice, and it has long been the law that juries are presumed to follow 

them,” McLaughlin v. State Farm Mut. Ins. Co., 30 F.3d 861, 870–71 (7th Cir. 1994), 

there are limits to that rule. See, e.g., United States v. Chaparro, 956 F.3d 462, 482 

(7th Cir. 2020) (noting that, although the usual view is that “limiting instructions 

cure everything,” the Seventh Circuit has “made clear” that “this presumption is 

rebuttable”) (citing Empress Casino Joliet Corp. v. Balmoral Racing Club, Inc., 831 

F.3d 815, 834 (7th Cir. 2016)). Because of the potentially inflammatory evidence 

regarding excessive force against minors and the nuanced difference between Monell

and respondeat superior liability, this case presents one of those perhaps-rare 

occasions where, in the Court’s view, limiting instructions are insufficient to 

ameliorate the potential prejudice to Defendants. 

Because one of Rule 42(b)’s criteria for bifurcation—avoidance of prejudice—is 

satisfied, the Court is not obligated to address judicial economy and efficiency. See 

Chlopek, 499 F.3d at 700 (If “one of [Rule 42(b)’s] criteria is met, the district court 

may order bifurcation . . . .”). But addressing these considerations briefly, the Court 

finds that both Plaintiffs and Defendants have persuasive arguments. Monell

discovery is notoriously burdensome and costly. See Williams v. City of Chicago, 315 

Case: 1:20-cv-03412 Document #: 126 Filed: 03/07/23 Page 9 of 12 PageID #:3125
10

F. Supp. 3d 1060, 1080 (N.D. Ill. 2018) (Willingness to bifurcate comes from 

recognition that “claims of municipal liability require an extensive amount of work 

on the part of plaintiff’s attorneys and experts, and an extraordinary amount of 

money must be spent in order to prepare and prove them.”) (cleaned up). But five of 

six years of the requested Monell data has already been compiled by Defendant City, 

which significantly reduces the burden of discovery. And although bifurcation will 

allow for a more efficient resolution of the claims against the Defendant Officers, it 

also delays resolution of the Monell claim against Defendant City and requires two 

separate trials. In the end, however, if judicial economy and efficiency entirely 

favored Plaintiffs—which it does not—the Court would still find that the avoidance 

of prejudice justifies bifurcation. 

Bifurcation is not permissible in any event if it would unfairly prejudice 

Plaintiffs. Chlopek, 499 F.3d at 700. There is, however, no unfair prejudice apparent 

to the Court. Plaintiffs contend that their “strong non-economic interest in police 

accountability and positive institutional reform” requires putting Defendant City on 

trial publicly (Dkt. 104 at 16–17), but nothing about today’s decision will frustrate 

that goal. Plaintiffs will still have the opportunity to present their Monell evidence, 

but that opportunity will consist of a second, later trial. And although bifurcation 

might require Plaintiffs to expend additional resources in preparing for two separate 

trials, that cost is both justified for the reasons provided above and, to a lesser extent, 

incident to Plaintiffs’ choice to bring a Monell claim in this action. 

Finally, the parties disagree whether the Defendant City’s liability depends on 

Case: 1:20-cv-03412 Document #: 126 Filed: 03/07/23 Page 10 of 12 PageID #:3126
11

the Defendant Officers’ liability. Although determining whether Heller or Thomas

provides the applicable rule might influence the Court’s efficiency analysis, it would 

not alleviate the Court’s concern with prejudice to the Defendants, which is the 

overarching justification for bifurcation. Moreover, Thomas addressed whether a 

municipality could ever be held liable under Monell when individual defendants were 

found not liable for the underlying episode—not whether that liability should be 

established in a single trial or separately. See Thomas, 604 F.3d at 305. Regardless, 

the Heller-or-Thomas issue can be revisited after the Defendant Officers’ potential 

liability is resolved at the first trial.1

Without deciding the issue, the Court notes that Heller likely governs because 

Thomas created a narrow exception to the rule that municipal liability is contingent 

on officer liability. Thomas only applies when the Monell claim is “factually distinct” 

from the claims against the individual officers. Swanigan, 775 F.3d at 962. The 

Monell claim here, premised on the Defendant Officers’ use of excessive force, is not 

factually distinct from the remaining claims. Although Plaintiffs do not bring a 

separate excessive force claim against the Defendant Officers, they do allege that the 

Officers conducted an unlawful search by “pointing guns at Sharon, 3-year-old [L.S.] 

and autistic Julius.” (Dkt. 27 ¶ 153.) In addition, Plaintiffs’ state law assault claim 

alleges that the Defendant Officers used “excessive” force by “pointing guns at close 

range at the plaintiffs.” (Id. ¶ 167.) The jury will be required to make an “excessive 

1 Likewise, the issue regarding Defendant City’s proposed consent to entry of judgment 

can be revisited after the first trial on the claims against the Defendant Officers because the 

issue would be mooted if the Defendant Officers are found not liable. 

Case: 1:20-cv-03412 Document #: 126 Filed: 03/07/23 Page 11 of 12 PageID #:3127
12

force” determination in the Officers’ trial even though there is no independent claim 

for excessive force.2 Bifurcation and a stay of discovery is thus warranted. Swanigan, 

775 F.3d at 962 (When Heller applies, “the judge’s decision to stay the Monell claim 

. . . was sensible, especially in light of the volume of civil-rights litigation that district 

courts must manage.”). 

For these reasons, bifurcation for trial of L.S.’s Monell claim from Plaintiffs’ 

remaining claims and a stay of discovery on the Monell claim is justified. 

IV. CONCLUSION 

Defendant City of Chicago’s motion to bifurcate and to stay discovery and trial 

on Plaintiff L.S.’s Monell claim (Dkt. 96) is granted.

2 Even if the jury is not required to make an excessive force finding in conjunction with 

any of the other claims brought against the Officer Defendants, this would not preclude 

bifurcation. See Tate v. City of Chicago, 2021 WL 4400982, at *2 (N.D. Ill. Sept. 27, 2021). As 

Judge Durkin explained, a “special interrogatory [can be given] to the jury asking for findings 

on whether any of the individual defendants used excessive force,” but because “Plaintiffs 

have not brought an excessive force claim against any of the individual officers, the Court 

would not enter judgment against any of them on the jury’s excessive force finding. Rather, 

that finding would pertain only to the claim against the City.” Id.
