MEMORANDUM OPINION AND ORDER

Plaintiffs Ronald Portis, Madric Lance and Emmett Lynch brought a second amended

class action complaint against defendant City of Chicago1 alleging that the City has a practice of

unconstitutionally delaying release of persons arrested for non-jailable ordinance violations that

are punishable by fine only. The court certified a class defined as:

All persons who, from May 1, 2000, through September 3, 2004, were arrested on

ordinance violations which carry no jail time in the City of Chicago and who were

detained for more than two hours after all administrative steps incident to the

arrest, except non-discretionary ministerial acts, were completed. The class is

further limited to those persons who (1) were not fingerprinted by defendants

after being brought into custody; and (2) were eligible for release on personal

recognizance bond pursuant to Rule 553(d) of the Illinois Supreme Court.

Plaintiffs previously moved for summary judgment of liability against the City. In Portis

v. City of Chicago, 510 F.Supp.2d 461 (N.D.Ill. 2007) (“Portis I”), the court denied plaintiffs’

motion, but later granted plaintiffs leave to renew it to clarify whether certain material facts were
2

genuinely in dispute. Because, as discussed below, the court is now satisfied that no genuine

issues of material fact remain for trial, and that plaintiffs are entitled to judgment as a matter of

law, plaintiffs’ renewed motion for summary judgment of liability is granted.

BACKGROUND 

 Plaintiffs are a class of individuals who were arrested and detained for non-jailable

ordinance violations under the City of Chicago’s Municipal Code. That is, the violations with

which the class members were charged are punishable by fine only, not by detention or

incarceration. Although plaintiffs could simply have been issued a ticket for the offenses, they

do not dispute the propriety of their arrests. Defendant, for its part, does not dispute that once

the necessary administrative steps incident to the class members’ arrests were completed, the

arrestees were eligible to be released on an individual recognizance bond (“I-bond”) pursuant to

Ill. Supp. Ct. Rule 553(d). 

Just as plaintiffs do not challenge the legality of their arrests, they do not complain about

the length of time they were detained while the City established that they were eligible for

release on an I-bond. The gravamen of plaintiffs’ complaint is that the City violated their Fourth

Amendment rights when it continued to detain them for more than two hours (and in some cases

for as long as 16 hours or more) after it completed all of the administrative steps necessary to

determine that they were eligible for release. In their first motion for summary judgment,

plaintiffs argued that once the class members’ eligibility for release had been established, any

remaining administrative steps were non-discretionary, ministerial, and often redundant, and

could not justify continuing to detain the class members any longer than the few minutes those

steps reasonably required. 
3

Although the court agreed with plaintiffs in theory, it appeared from the record that the

order in which certain administrative steps were taken was disputed. Because the court could not

resolve the legal issues presented by plaintiffs’ claims until it had a firm grasp on when, in the

sequence of administrative steps, plaintiffs’ eligibility for release had been conclusively

established, it denied summary judgment. Plaintiffs have now renewed their efforts to show that

the administrative steps the City took in processing the class members’ arrests are indeed

undisputed, and that the class members had been determined eligible for release, at the latest, by

the time they were issued a Central Booking (“CB”) number, as discussed below. Plaintiffs

again urge the court to find that their continued detention in excess of two hours after receiving a

CB number violates the Fourth Amendment as a matter of law. 

LEGAL STANDARDS

The standard for summary judgment remains unchanged since the court decided Portis I. 

As before, summary judgment is proper when the moving papers and affidavits show that there

is no genuine issue of material fact and that the movant is entitled to judgment as a matter of law. 

Fed. R. Civ. P. 56(c); Celotex Corp. v. Catrett, 477 U.S. 317, 322 (1986). Once the moving

party has established undisputed facts entitling that party to judgment, the non-moving party

must go beyond the pleadings and set forth specific facts showing that there is a genuine issue

for trial. Fed. R. Civ. P. 56(e); Becker v. Tenenbaum-Hill Associates, Inc., 914 F.2d 107, 110

(7th Cir. 1990). The court considers the record as a whole and draws all reasonable inferences in

the light most favorable to the party opposing summary judgment. Fisher v. Transco ServicesMilwaukee, Inc., 979 F.2d 1239, 1242 (7th Cir. 1992).
4

A genuine issue of material fact exists when “the evidence is such that a reasonable jury

could return a verdict for the non-moving party.” Anderson v. Liberty Lobby, Inc., 477 U.S.

242, 248 (1986). The non-moving party, however, “must do more than simply show that there is

some metaphysical doubt as to the material facts.” Matsushita Electric Indus. Co., Ltd. v. Zenith

Radio Corp., 475 U.S. 574, 586 (1986). “The mere existence of a scintilla of evidence in support

of the [non-moving party’s] position will be insufficient; there must be evidence on which the

jury could reasonably find for [the non-moving party].” Anderson, 477 U.S. at 252.

To assist courts in sorting out which facts, if any, are genuinely in dispute, the Northern

District of Illinois adopted Local Rule (“L.R.”) 56.1. Having discussed the requirements of L.R.

56.1 in detail in Portis I, the court need not revisit them here. It bears repeating, however, that

the court is entitled to demand strict adherence to L.R. 56.1 and may refuse to consider facts

presented in a manner that does not comport with the rule. Ciomber v. Cooperative Plus, Inc.,

527 F.3d 635, 643 (7th Cir. 2008). In Portis I, the court admonished both parties for failing to

observe the requirements of L.R. 56.1, deploring in particular defendant’s consistently improper,

obfuscatory, and argumentative statements. Portis I, at 464. Nevertheless, the court tried to

piece together the material facts as best it could without the aid of a proper L.R. 56.1 “roadmap,”

and concluded that the order in which certain administrative steps were taken appeared to be in

dispute. As a result, the court denied summary judgment “despite the strong possibility that had

[the] motion been prosecuted properly plaintiffs would have been able to demonstrate that

defendant has violated the constitutional rights of the plaintiff class.” Portis I, at 465. 

If plaintiffs succeed in their renewed attempt to show that no material facts are in dispute,

they must then convince the court that class members’ detention in excess of two hours after they

Defendant’s claim that in some instances, class members bypassed the holding area and

were taken directly to a cell is not supported by the record, as discussed below, and does not give

rise to a material dispute.

were determined to be eligible for release is unreasonably lengthy under Fourth Amendment

standards. Chortek v. City of Milwaukee, 356 F.3d 740, at 747 (citing Gerstein v. Pugh, 420

U.S. 103 (1975)). If plaintiffs are successful on that front as well, their final burden is to

demonstrate that the City is liable under Monell v. Dep’t of Soc. Serv. Of City of New York, 436

U.S. 658, 694 (1978), for the Fourth Amendment violations. Under Monell, plaintiffs must

show that the violations were caused by a policy or custom carried out by the City’s lawmakers

“or by those whose edicts or acts may fairly be said to represent an official policy.” Portis I, at

469 (citing Chortek, at 748). 

DISCUSSION

The City’s Arrest Procedures

In Portis I, the court summarized its understanding of the City’s basic arrest processing

procedure. The first steps, which are not materially disputed, are that an individual suspected of

an ordinance violation is arrested, searched, transported to a police station, and placed in a

holding area.2 At the station, the arresting officer enters the individual’s available identifying

information into the “hot desk” system, which has access to multiple law enforcement databases,

to determine whether the individual is wanted on any outstanding warrants. Either before, after,

or while completing this name/warrant check, the arresting officer also fills out an arrest report

and a quasi-criminal complaint. 

The arresting officer takes the paperwork generated by these steps, along with any other

reports, to the desk sergeant, who reviews it and charges the arrestee. The paperwork then goes
3

Until June 7, 2002, a subsequent name/warrant check was performed on all arrestees by

faxing a copy of the Arrest Report to the Field Inquiry Section. This step was apparently

determined to be redundant, since it was based on the same information and accessed the same

databases as the “hot desk,” and was therefore discontinued.

6

to the watch commander, who reviews the paperwork and the charge, determines whether the

individual has been satisfactorily identified, and makes an initial determination of probable

cause. At that point the arrestee is taken from the holding area to the lockup.

The lockup keeper reviews the paperwork and generates a CB number using information

from the arrest report. Meanwhile, arrestees are prepared for custody: they are again searched,

their belongings are inventoried, they fill out a medical screening form, and they are allowed to

use the telephone. During this time, arrestees whose identity and/or warrant status was deemed

inconclusive by the watch commander are fingerprinted, and additional name/warrant checks are

run.3

 At the end of these additional steps, the watch commander again reviews the paperwork

and signs off on the final charges. A desk officer then prepares an I-bond for the arrestee’s

signature. Once the individual has signed the I-bond, his or her belongings are returned, and the

individual is released.

According to plaintiffs, class members became eligible for release, at the latest, by the

time they received the CB number. Defendant contends, however, that a CB number could issue

before (1) an arrested individual’s identity was established and (2) it was determined whether

that individual was the subject of any outstanding warrants. In such cases, defendant argues, one

or more subsequent steps could be required to determine whether that individual was eligible for

release. Because the court could not, based on the parties’ previous L.R. 56.1 submissions,

conclude that class members had systematically been determined eligible for release before
4

This is essentially the relief requested in plaintiffs’ pending motion to strike defendant’s

L.R. 56.1 responses. The court considered the parties’ respective arguments relating to that

motion jointly with their summary judgment arguments and denies the motion to strike (Docket

No. 505) as moot in light of the present ruling. 

5

Although the court, like the parties, often uses the present tense to refer to the City’s

practice, it is mindful that the City’s policies and/or practices have changed in material respects

since the end of the defined class period.

7

receiving a CB number, it was left with no identifiable starting point for measuring the allegedly

unconstitutional detention.

Mercifully, plaintiffs’ renewed L.R. 56.1 statement heeds the court’s previous directives,

and more importantly, it resolves the apparent dispute identified in Portis I. Defendant,

meanwhile, persists in muddling the record with argumentative and misleading responses. 

Wading through the morass of defendant’s improper submissions, the court was tempted more

than once to throw up its hands and deem the entirety of plaintiffs’ L.R. 56.1 statement

undisputed.4 Reluctant to punish the City for the failings of its counsel, however, and in an

effort to bring this drawn-out litigation to a meaningful close, the court persevered. Yet the

substantive result is the same, because a considered analysis of defendant’s responses reveals

little more than smoke and mirrors. 

Though the standard processing procedure summarized above reflects the general

sequence of the various steps,5 it is helpful to set forth relevant portions in a numbered list,

highlighting in bold the crux of the apparent dispute that defeated summary judgment in Portis I:

1. The class member is arrested, searched, and transported to a police station; 

2. The class member is placed in a holding area;

3. The arresting officer completes an arrest report;
6

In ¶ 21 of its L.R. 56.1 statement of additional material facts, the City sets forth its

procedures in bullet-point format.

8

4. A quasi-criminal complaint is completed;

5. An initial name/warrant check is performed and the results are obtained

[*this step may take place at different points after arrival at the police station in

step 1, but in any event prior to the next step]

6. A desk sergeant reviews the arrest report, quasi-criminal complaint, and any other

reports (i.e., the “paperwork”) and charges the class member;

7. The arresting officer takes the class member’s paperwork to the watch

commander, who ensures that the person has been identified correctly and

makes the preliminary probable cause determination (i.e., determines that

the charges are appropriate);

8. The class member is taken to lockup, where the lockup keeper reviews his or her

paperwork and accepts the class member, and where the class member is again

searched, permitted to make phone calls, and receives a computer-generated CB

number.

By and large, the above sequence is consistent with the City’s own account of its

procedures.6

 It is also consistent with the Chicago Police Department General Orders (“GOs”),

which require the initial name/warrant check to be completed before the desk sergeant’s review

of the paperwork (step 6), and which the parties agree occurs before the watch commander’s

review (step 7). Nevertheless, defendant maintains that, “in practice the charging paperwork

(arrest report and complaint) were brought to the watch commander for initial review [step 7] 

prior to completion of the initial name/warrant check [step 5].” Portis I, at 469. (Emphasis

added.) 

The court is now convinced, however, that that is not what the evidence establishes. 

Instead, the undisputed evidence shows that according to the City’s general practice, an initial

name/warrant check was consistently performed, and completed (to the best of the arresting
9

officer’s ability using the information and resources available), prior to the watch commander’s

review. If the results of that check were unsatisfactory or inconclusive, the watch commander

would require subsequent checks based on information obtained from fingerprinting. In such

cases, the arrestee could, indeed, be taken to the lockup before an arrestee’s name/warrant status

was ascertained. But as plaintiffs correctly note, because the class is limited, by definition, to

those cases in which fingerprinting was not ordered, the identity and warrant status of class

members was, in each case, satisfactorily determined based on the information resulting from the

initial name/warrant check.

The court also agrees with plaintiffs that defendant’s L.R. 56.1 responses conflate the

evidence relating to initial name/warrant checks with evidence relating to subsequent checks. 

The result is misleading because it purports to show a genuine factual dispute, when in fact there

is none. An example of this pervasive problem follows:

STATEMENT 10

10. Typically, the Arresting Officer does not present the Class

Members’ paperwork to the Desk Sergeant until he/she has completed the name

check and determined to the best of his/her ability the Class Members’ identity

and warrant status. Exh. 3, Cobb dep. At 25:17-26:5; Exh. 13, Richmond dep. At

49:24-50:15.

This statement makes a concise, intelligible assertion about the City’s typical practice

and properly lends itself to a response of “admit” or “deny.” It is also supported by the record

evidence. Indeed, the statement incorporates the very terms used by Officer Cobb, who testified:

Q And are all of the steps we just discussed completed before you go to the

desk sergeant, the filling out of the complaint and the completing of the

name and warrant check and any other computer checks that you think are

appropriate?
7

Defendant’s counsel objected on the ground that the question was hypothetical. The

court does not find the question improper and sees no basis for excluding the testimony elicited.

10

[]7

A When an arresting officer is – to the best of their ability is satisfied that

they know who they have in custody and what the correct charges would

be, the desk sergeant does have to approve everything that the arresting

officer just completed.

Q So when the arresting officer is satisfied to the best of his ability that he

knows the identity of the person in custody and there are no warrants, and

he’s finished the paperwork, he then presents it to the desk sergeant?

A Yes, sir.

Defendant responds to this statement as follows:

RESPONSE: Controverted and unsupported. Controverted because multiple

officers have testified that the arrestee’s identity or the absence of any warrants has not

necessarily been verified at the time the arrest report is brought to the Desk Sergeant. Def. Exh.

8, Sodini 8/22/05 Dep. at 103:13-16; Def. Ex. 1, Sodini 10/29/03 Dep. at 67:8-16; Def. Ex. 10,

Wedster 9/20/05 Dep. at 129:20-130:6; Def. Ex. 11, Caver-Elder Dep. at 65:7-14. Multiple

officers have also testified that many of these tasks performed by the Arresting Officer may not

be completed until after he has handed control of the arrestee over to lockup personnel, which

may or may not have occurred before presentment of the paperwork to the Desk Sergeant. Def.

Ex. 15, Bay Dep. at 57:24-58:8 (completion of criminal complaints and “plethora of additional

documents” may be taken care of after arrestee is placed in lockup); Def. Ex. 8, Sodini 8/22/05

Dep. at 71:19-23 (criminal complaint form may be completed after the issuance of a CB

number); Def. Ex. 9, Smith Dep. at 24:8-12 (in effort to “expedite,” name check may be

performed after the desk officer has clerked the arrest report). Unsupported because Plaintiffs do

not indicate what hypothetical “Class Member,” “Arresting Officer,” or “Desk Sergeant” they

are referring to and nothing in the cited evidence indicates that these procedures occur in the

order described with respect to all arrests, let alone the Class Members’ arrests, and any

application of the cited evidence to establish the statement requires impermissible inferences be

made against the non-movant.

Defendant’s response is disingenuous from the outset. Whether or not an arrestee’s

identity has been “verified” is not the point. Plaintiffs do not assert (in this statement or any

other) that the name/warrant check conducted by the arresting officer is sufficient to “verify” an
11

arrestee’s name/warrant status. The facts for which plaintiffs do seek admission, and which the

evidence taken as a whole supports, is that typically, prior to bringing an arrestee’s paperwork to

the desk sergeant, an arresting officer uses his or her best efforts, based on the resources

available at the time, to identify the name and warrant status of the arrested individual. The first

part of defendant’s response (including the citations to the record) does not controvert or even

respond to plaintiffs’ statement. 

Defendant’s second assertion is confusing (the demonstrative phrase “these tasks”

lacking any antecedent referent) and largely non-responsive. As noted, plaintiffs’ statement

makes a straightforward assertion, supported by the record, about the arresting officer’s

responsibility for ascertaining the identity and warrant status of an arrested individual. Even

assuming that “these tasks” refers to some tasks beyond the initial name/warrant check that may,

in some cases, be required to “verify” an arrestee’s identity, such tasks are irrelevant because

they were not necessary to identify the name/warrant status of any class member. Moreover, two

of the three record citations defendant offers that evoke additional tasks cite the completion of

criminal complaints. That an arresting officer also must complete a complaint form has nothing

to do with whether the officer uses his or her best efforts to identify an individual prior to

bringing the paperwork to the desk sergeant. Defendant’s invocation of that task is entirely nonresponsive. Moreover, testimony about criminal complaints is irrelevant in any event, since

quasi-criminal (as opposed to criminal) complaints are used for non-jailable ordinance

violations. The only portion of defendant’s statement that even remotely responds to

plaintiffs’ statement is the testimony by Officer Smith that when a computer is not immediately

available for an arresting officer to run a name/warrant check, the officer may take the
8

In this response, as in many others, defendant complains that plaintiffs’ statement is

“hypothetical” because it does not refer to specific individuals. This objection is nonsense. To

the extent fact witnesses are able, based on their personal knowledge or experience, to make

observations about general practices, the court finds nothing improper in allowing them to testify

about these observations. Defendant is free to argue that such evidence should be accorded little

probative value; but defendant’s brief, not its L.R. 56.1 response, is the proper venue for such

argument.

12

paperwork to a desk sergeant before completing the check. Even assuming that Officer Smith’s

testimony accurately reflects the way arresting officers sometimes “expedite” the paperwork,

however, that testimony, standing alone, is insufficient to controvert plaintiffs’ statement about

the City’s general practice, which is consistent with the evidentiary record as a whole.

Finally, defendant’s third assertion about the “hypothetical” nature of plaintiffs’

statement (which is repeated throughout its responses) consists of improper argument, does not

point to any facts that controvert plaintiffs’ general assertion, and merits no serious

consideration.8

 Sadly, most of defendant’s responses are similarly unhelpful. The following is another

example that goes to the heart of the potential dispute identified in Portis I:

STATEMENT 30

30. The initial name/warrant check has been completed before the

Watch Commander makes the initial determination of probable cause. Exh. 8,

Malinowski dep. at 24:22-25:5; Exh. 25, Schmit dep. at 58:23-59:11; Exh. 10,

Smith dep. at 24:16-21.

Each of plaintiffs’ citations to the record supports this straightforward assertion. 

Defendant responds as follows:

RESPONSE: Controverted and unsupported. Controverted because multiple

officers have testified that it is not necessary that the Watch Commander has confirmed that the

name check revealed no warrants for the arrestee prior to approving probable cause. Def. Exh. 8,

Sodini 8/22/05 Dep. at 103:13-16; Def. Ex. 1, Sodini 10/29/03 Dep. at 67:8-16; Def. Ex. 10,
9

Defendant’s motion to strike plaintiffs’ reply in support of their L.R. 56.1 statements

(Docket No. 503) is denied. In light of the nature of defendant’s responses, plaintiffs were

justified in filing a reply.

13

Wedster 9/20/05 Dep. at 129:20-130:6; Def. Ex. 11, Caver-Elder Dep. at 65:7-14. Unsupported

because Plaintiffs do not indicate what hypothetical “Watch Commander” they are referring to

and nothing in the cited evidence indicates that these procedures occur in all arrests, let alone the

arrests of the Class Members, and any application to all arrests requires an impermissible

inference be made against the non-movant.

This response mirrors the response to Statement 10 but is cast in slightly different terms. 

Defendant this time responds to a statement about an initial name/warrant check with an

assertion disputing what the watch commander has “confirmed.” Notably, defendant cites the

very same evidence it pointed to earlier, when it asserted that an arrestee’s name and warrant

status had not yet been “verified” upon completion of the initial name/warrant check. The

remainder of defendant’s response is the same improper argument as above, and again fails to set

forth any facts to controvert plaintiffs’ statement. 

The preceding submissions are characteristic of the parties’ respective L.R. 56.1

statements and responses, and it is unnecessary to discuss each of the factual assertions

establishing the nature and order of the City’s processing procedures in detail.9

 Plaintiffs’

account of the procedures is supported by the record, and defendant’s responses are inadequate

to controvert that account in any material way. Nevertheless, one further ostensible dispute

bears comment. Defendant gives substantial air time, in an effort to controvert a number of

plaintiffs’ assertions about steps that occur between the time class members arrived at the police

station and the time they were placed in lockup, to the “fact” that named plaintiff Ronald Portis

testified he was taken to lockup immediately upon arrival at the police station. Indeed,

references to Portis’s testimony are at the front and center of defendant’s attack on plaintiffs’
10Indeed, Portis’s testimony immediately preceding the City’s “walk me through the

steps” question reflects that he was arrested on more than one occasion, and that he was

confused about what happened on which occasion.

14

factual assertions–a number of which are directly supported by the testimony of Ronald Sodini,

the City’s 30(b)(6) witness designated as knowledgeable about the Chicago Police Department’s

procedures and practices--regarding the steps that occur before an arrestee is placed in lockup. 

And for good reason: would not plaintiffs have a problem if the testimony of their named

representative controverted one of the critical factual underpinnings of their case? The court

thought so, and took the time to review the Portis testimony carefully. 

In his deposition, in response to the City’s request that Portis “walk [him] through what

happened at the station when [Portis] arrived,” Portis testified: 

I don’t know what they do as they put you in the lockup, they search you,

put you in the cell, and they call you out, and fingerprint you and take

your picture. I don’t think they did that, though. I don’t remember. 

That’s the usual procedure. 

On its face, Portis’ testimony is muddled and equivocating. Indeed, the first three words

of his response are “I don’t know.” He then lists several procedures that do not apply to

individuals arrested for non-jailable ordinance violations (fingerprinting and photographing), and

no sooner has he recited those procedures than he retracts some or perhaps all of his narrative,

saying that he doesn’t remember what happened. Furthermore, it is not at all clear that Portis

was focusing on the temporal aspect of the question, as defendant now wishes to do; indeed,

Portis’ testimony reads more like a scrambled account of various procedures he had been

through at one time or another than his actual recollection of an exact sequence of events,

beginning with his arrival at the police station on the day in question.10
15

While it is not the court’s function at summary judgment to “weigh the evidence and

decide on the merits,” Anderson, at 249, neither must the court allow a case proceed to trial

based on merely a “metaphysical doubt as to the material facts.” Matsushita, at 586. “It is well

accepted that the purpose of summary judgment is to prevent an unnecessary trial where, on the

basis of the pleadings and supporting documents, there remains no material issue of fact to be

tried.” Moore v. Marketplace Restaurant, Inc., 754 F.2d 1336, 1339 (citing Kirk v. Home

Indemnity Co., 431 F.2d 554, 559 (7th Cir.1970)). Here, the evidence taken as a whole firmly

supports plaintiffs’ characterization of the steps occurring before an arrestee is taken to lockup,

and no measure of artful advocacy by defendant can transform Portis’s faltering testimony into a

triable dispute.

In sum, plaintiffs have successfully demonstrated that no triable issues remain regarding

the nature and order of the steps taken in processing class members. The court is now satisfied

that the evidence shows that class members had been determined to be eligible for release on an

I-bond no later than by the time they received a CB number.

Statistical Evidence of the City’s Procedures

The court is equally convinced that undisputed facts prove that the prolonged detention

of class members after the issuance of CB numbers was a city-wide phenomenon. Plaintiffs rely

on the analysis of their expert, Thomas DiPrete, to establish the statistical basis for their claim

that these detentions were systematic. Defendant argues that DiPrete’s expert report is

“unauthenticated, unsubstantiated, hearsay” and should not be considered. But Mr. DiPrete’s

report was accompanied by his sworn affidavit attesting to the report’s authenticity and to its

factual foundation. Moreover, the affidavit stated that Mr. DiPrete could testify competently to
11Defendant also complains that DiPrete’s use of the time class members received a CB

number to begin measuring the time of detention reflects a “self-serving” selection by plaintiffs’

counsel. As explained above, however, the court agrees with plaintiffs that issuance of a CB

number is a meaningful indicator of when class members’ eligibility for release was established,

and that it is therefore a rational starting point for DiPrete’s calculations.

12Plaintiffs also cite the finding that 75% of the arrests resulted in a detention time of four

or more hours from arrest to release. This finding is irrelevant to plaintiffs’ claims, however,

and its consideration only stands to obscure what the court understands to be plaintiffs’ theory of

the case. 

16

the contents of the report, if called upon to do so. Defendant’s objection is thus unfounded. See

Winskunas v. Birnbaum, 23 F.3d 1264, 1267-68 (evidence submitted at summary judgment must

be admissible in content, but not in form). 

Defendant also complains that Mr. DiPrete’s methodology was flawed because the data

he used did not reflect certain information, such as the time each class member entered the

lockup, the order in which the processing steps were completed, or factors that may have

accounted for processing delays. But defendant fails to explain how that information would have

any bearing on the principal issue on which Mr. DiPrete opines: the statistical prevalence,

throughout the City’s districts, of prolonged detention of class members after they have been

determined eligible for release.11 Moreover, other than the general assertion that defendant’s

own expert, Robert LaLonde, “refutes the claims made in DiPrete’s report and testimony,”

defendant does not identify a shred of evidence to controvert any of the statistics plaintiffs assert,

including: that of 18,031 arrests, 80% resulted in a detention of two hours or more from the time

that a CB number was issued to the time of release; that approximately 95% of the class

members were detained for one hour or more; and that the mean detention time was 4.42 hours

and the median was 3.75 hours.12 To the contrary, in his deposition, LaLonde testified that he
17

was able to replicate all of DiPrete’s calculations and found them to be accurate. The court

deems these statistics undisputed.

Fourth Amendment Violations

The factual landscape thus established, the court turns to the legal question of whether

detention in excess of two hours after an individual has been has been found eligible for release

violates the Fourth Amendment. Both the Supreme Court and the Seventh Circuit have had

occasion to address the limits that the Fourth Amendment places upon detention of individuals

subject to arrest. In Gerstein v. Pugh, 420 U.S. 103 (1975), the Supreme Court established that

the Fourth Amendment allows a person suspected of a crime to be arrested and held “for a brief

period of detention to take the administrative steps incident to arrest.” Id., at 113-114. The

Court has never said, however, how long the “brief period” may be. See Gramenos v. Jewel

Companies, Inc., 797 F.2d 432, 437 (7th Cir. 1986). Nevertheless, Gerstein is unequivocal on

this point: at the end of the brief period–whatever it may be–the police must let the suspect go. 

Id.

In County of Riverside v. McLaughlin, 500 U.S. 44 (1991), the Court established a

presumptively reasonable forty-eight hour window between an arrest and a probable cause

hearing. In Chortek v. City of Milwaukee, 356 F.3d 740 (7th Cir. 2004), however, the Seventh

Circuit clarified that the County of Riverside presumption did not justify lengthy (but less than

forty-eight hour) police processing times in cases such as this, where no probable cause hearings

were contemplated. The Chortek court noted that under County of Riverside, unreasonable

delays even within the forty-eight hour period may be “constitutionally troublesome.” Chortek,

at 746. Indeed, at least since Moore v. Marketplace, 754 F.2d 1336, 1350-51 (7th Cir. 1985), the
18

Seventh Circuit has made clear that the court must examine the circumstances to determine

whether pre-trial detention is unreasonably lengthy. In Gramenos, the Seventh Circuit observed

that, “if the police choose to perform time-consuming tasks after an arrest, perhaps they must do

so on their own time rather than the suspect’s,” and remanded so that the lower court could

consider whether the administrative tasks carried out incident to arrest justified the length of the

challenged detention. Gramenos, at 437. 

While these cases have analyzed, in different factual scenarios, what duration of time can

appropriately be considered “brief” under Gerstein, none has examined Gerstein’s separate and

distinct requirement that pre-trial detention must also be “incident to arrest.” In particular,

neither Gerstein nor the cases in its wake contemplated whether administrative steps that take

place after probable cause has been established and after a detainee has been determined eligible

for release can properly be characterized as “incident to arrest.” As a matter of first impression,

the court holds that they cannot.

This holding is consistent with the rationale articulated by both the Supreme Court and

the Seventh Circuit. In Gerstein, the Court acknowledged that allowing police officers to make

summary arrests based upon their on-the-scene assessment of probable cause, and to detain

individuals arrested in this manner for a brief processing period, is a “practical compromise”

between individual rights and the realistic demands of law enforcement. Id., at 113-14. The

Court cautioned, however, that because “the consequences of prolonged detention may be more

serious than the interference occasioned by arrest,” detention following a warrantless arrest must

be no longer than necessary to achieve legitimate law enforcement objectives. See id. And if

the Seventh Circuit’s admonishment in Gramenos that police must consider undertaking time-
13The court takes this opportunity to note that the efficiencies achieved by eliminating

unnecessary processing steps would seem to maximize law enforcement interests as well by

conserving resources.

19

consuming tasks “on their own time” means anything, it means that the administrative steps

performed while an arrestee is in custody must be limited to those that are reasonably necessary

to balance legitimate law enforcement needs with individual liberty interests. Any steps taken

by the City that lengthened detention after class members had become eligible for release fail

this balancing test.

If Gerstein and its progeny set limits to the time that law enforcement officials may take

to complete the administrative steps incident to arrest, then this holding sets limits to the time

those officials may take to complete the administrative steps incident to release. Indeed, once

the watch commander had determined probable cause and established that the class members

were eligible for release, there was nothing (or next to nothing) left to do but to release them.13

The court need not decide whether, under the City’s practice, some time of detention that is less

than two hours may be justified following the issuance of the CB number. Plaintiffs have argued

that two hours is excessive under the Fourth Amendment, and as a matter of law, the court

agrees.

Liability Under Monell

Having found that the practice described by plaintiffs violates the Fourth Amendment, it

is only a short step, on the undisputed facts of this case, to hold the City liable for these

violations. Plaintiffs argue that the City is liable under Monell v. Dep’t of Soc. Serv. Of New

York, 436 U.S. 658 (1978), on the ground that the City’s practice of detaining class members in

excess of two hours after issuing CB numbers represents a “widespread practice that, although
20

not authorized by written law or express municipal policy, is so permanent and well settled as to

constitute a ‘custom or usage’ with the force of law.” City of St. Louis v. Praprotnik, 485 U.S.

112, 127 (1988). This is, indeed, the only reasonable conclusion to draw from the statistical

analysis of plaintiffs’ expert Dr. DiPrete, which, as discussed above, is based on the City’s own

statistics. Defendant urges the court to discount DiPrete’s findings because, in defendant’s

words, “statistics are not irrefutable.” But while this caveat may be sound in principle, it rings

hollow here, since defendant has not offered any evidence to refute DiPrete’s findings. 

Defendant’s substantive arguments against liability under Monell are equally without

merit. Defendant first focuses on the purported factual dispute over whether the issuance of a

CB number necessarily follows the determinations of probable cause and eligibility for release of 

class members. As discussed above, there is no genuine dispute on this issue. Defendant next

claims that differences in processing times across districts defeats Monell liability. But what

DiPrete’s analysis shows is that regardless of any variation across districts, as a result of the

manner in which the City’s various police districts implemented the GOs, nearly 80% of all

arrestees were detained in excess of two hours after receiving CB numbers. This is sufficient to

demonstrate a widespread pattern or practice and to distinguish cases such as Jones v. City of

Chicago, on which defendant relies. 

In Jones, the Seventh Circuit held that the City was not liable for the misconduct of a

physician employed by the City who was charged with assaulting two of his patients. The court

noted that, “by all accounts, [the physician’s] assault on [the first plaintiff] was the first of its

type ever brought to the City’s attention,” and likened the case to others in which the acts alleged

were found to be “isolated act[s] of an employee.” Jones, at 203-04. The Jones court declined to
21

hold the City liable under Monell because the plaintiffs “clearly present[ed] no facts that tend to

show [the physician’s] misconduct ‘implements or executes a policy statement, ordinance,

regulation, or decision officially adopted and promulgated by the City.’” Id., at 204 (citing

Monell, internal brackets omitted). 

By contrast, the violations in the instant case resulted from the City’s implementation of

the GOs and were, as demonstrated by Dr. DiPrete’s undisputed statistical analysis, systemic and

widespread throughout the City. The Jones court specifically distinguished such situations from

the one then under scrutiny, observing that “where the injury is caused by ‘faults systemic in

nature,’” Monell liability is appropriate. Jones, at 204 (internal citations omitted). 

Similarly, the City’s argument that plaintiffs must prove that a specific policymaker had

actual knowledge of the violations but was “deliberately indifferent” to them is meritless. The

cases defendant cites for these propositions, including Jett v. Dallas Ind. Sch. Dist., 491 U.S. 701

(1989), Gable v. City of Chicago, 296 F.3d 531 (7th Cir. 2002), and McNabola v. Chicago

Transit Auth., 10 F.3d 501 (7th Cir. 1991), are unavailing. 

In Jett, the issue was whether the decision by a school district’s superintendent to

reassign a particular high school teacher and coach could be imputed to the municipality. That

question is patently distinct from the issue of whether widespread violations that result from the

day-to-day implementation of a specific policy are properly attributable to the City. In Gable,

the plaintiffs’ Monell claims were doomed because the court found that the plaintiffs had failed

to identify any municipal policy relating to the handful of violations they alleged. 

Finally, in McNabola, the Seventh Circuit held that the City was liable under Monell

based on its constructive knowledge of a pattern of discriminatory employment decisions taken
22

by the Chicago Transit Authority. McNabola supports, rather than undermines, plaintiffs’

position. Indeed, the court noted that “the longstanding or widespread nature of a particular

practice would support the inference that policymaking officials ‘must have known about it but

failed to stop it.’” McNabola, at 511 (internal citations omitted). Because defendant has failed to

offer any evidence to refute plaintiffs’ proof that the practice of detaining class members in

violation of the Fourth Amendment is systemic and widespread, that is the only reasonable

inference that can be drawn in this case.

CONCLUSION

For the reasons set forth above, plaintiffs’ renewed motion for summary judgment of

liability is granted. This motion is set for a status report on September 23, 2008, at 9:15 am, to

set procedures for determining damages and concluding this litigation.

ENTER: September 9, 2008
