v.

Sheriff of Kit Carson County, Colorado,

Defendant-Appellant,

and

WILLIS E. BODEN, individually and as Deputy

Sheriff of Kit Carson County, Colorado,

No. 07-1092

Appeal from the United States District Court

for the District of Colorado

(D.C. No. 1:03-CV-1008-WDM-PAC)

Robert M. Liechty (Jonathan A. Cross with him on the briefs) of Cross & Liechty,

P.C., Denver, Colorado, for Defendant-Appellant.

Peter R. Bornstein of Denver, Colorado, for Plaintiff-Appellee.

Before MURPHY, SEYMOUR and MCCONNELL, Circuit Judges.

SEYMOUR, Circuit Judge.

 Mr. Goering submitted this appeal following a week-long jury trial, but

provided only snippets of the trial transcript. He included excerpts of the direct

examination of two witnesses, but omitted the cross-examination of those

witnesses and the testimony of other key witnesses, such as himself and Mr.

Cassady. The parts of the testimony he did provide are so choppy it is often

difficult to discern the subject matter of the question and the witness’ full answer. 

Even the courtroom minutes are not included in full, so we do not know who

testified at trial. 

It is the appellant’s responsibility to provide the record. See 10th Cir. R.

Thomas J. Cassady brought this § 1983 action against Steven E. Goering. 

Mr. Cassady alleged Sheriff Goering violated his Fourth Amendment right to be

free from unreasonable searches and seizures. A jury found for Mr. Cassady at

the first trial, but he was awarded a new trial due to a prejudicially low damages

award. Sheriff Goering filed a Rule 50(b) Motion for Judgment as a Matter of

Law and Renewed Motion Based on Qualified Immunity. He appeals the district

court’s amended order rejecting his qualified immunity claim. Because the

warrant permits a general search and seizure of “all other evidence of criminal

activity,” we hold it was a general warrant prohibited by the Fourth Amendment. 

Accordingly, we affirm the denial of qualified immunity.

I.

The incident that gave rise to the search and seizure at issue involved a

dispute between Mr. Cassady and Gary Queen over grain owned by Mr. Queen

and stored on Mr. Cassady’s farm in Kit Carson County, Colorado.1

 Mr. Cassady

(...continued)

30.1(A)(1) (“The appellant must file an appendix sufficient for considering and

deciding the issues on appeal.”); 10th Cir. R. 10.3(A) (“Counsel must designate a

record on appeal that is sufficient for considering and deciding the appellate

issues.”); see also Travelers Indem. Co. v. Accurate Autobody, Inc., 340 F.3d

1118, 1119 (10th Cir. 2003) (“A party who seeks to reverse the decision of a

district court must provide an adequate record for this court to determine that

error was committed.”); Dikeman v. Nat’l Educators, Inc., 81 F.3d 949, 955 (10th

Cir. 1996) (“An appellant who provides an inadequate record does so at his

peril.”). Mr. Goering’s lack of evidence is particularly odd given his argument

that he could not file an interlocutory appeal prior to the first trial, after the

district court denied his summary judgment motion, because there were questions

of fact for the jury to decide before the record would be complete. See Aplt. Br.

at 4. While Mr. Goering makes numerous references to the trial record and what

it purportedly supports, we are unable to confirm these assertions because he did

not provide the full trial transcript. The facts are therefore taken primarily from

the district court’s July 21, 2005 order denying Mr. Goering’s Motion for

Summary Judgment.

-3-

attempted to cut off Mr. Queen’s access to the grain, claiming that Mr. Queen had

not paid for the storage, which led to a physical altercation between Mr. Cassady

and Mr. Queen. Both parties called the police – Mr. Cassady requesting help to

remove Mr. Queen from his farm, and Mr. Queen reporting that Mr. Cassady had

assaulted him after he saw marijuana plants on the property.

Sheriff Goering responded to the call, with Deputy Sheriff Willis Boden

joining him. Mr. Queen told Sheriff Goering that he had seen marijuana plants

inside a quonset hut on Mr. Cassady’s farm, that Mr. Cassady had attacked him,

and that he had seen a handgun in Mr. Cassady’s truck. Mr. Queen did not have

any visible injuries.

Although Mr. Cassady, unlike Mr. Queen, was suffering from visible
-4-

injuries, Sheriff Goering determined there was probable cause to arrest Mr.

Cassady. After placing him under arrest, the officers conducted a “security

sweep” of the open areas and buildings on the farm, but did not search the locked

quonset hut.

Sheriff Goering directed Deputy Boden to obtain a search warrant while he

remained behind at the farm. Boden had never before sought a drug-related

search warrant. He admitted to not knowing what he was doing, so he requested

help from an officer in another police department who had experience with drugrelated investigations. After obtaining the warrant, the officers searched the farm

and found a large marijuana operation. Sheriff Goering contacted the Drug

Enforcement Administration (“DEA”), and he arranged for his own officers to

watch the farm overnight. He allowed Mr. Queen to come onto the farm and take

his grain, despite his knowledge that Mr. Cassady and Mr. Queen were in a

dispute over its ownership. The DEA agents arrived the following morning and

Sheriff Goering remained on the farm while the DEA agents conducted the

search. 

The district court described the state of the farm upon Mr. Cassady’s

return:

 When Cassady returned home, the farm was a mess. His house had

been ransacked, there was trash and his personal property on the

floor, newly hatched chicks had been killed by being removed from

their incubators, and most of his poultry was missing. Additionally,

coolers in the Quonset hut were destroyed, food in its freezers had
-5-

rotted, and insulation had been torn out of its wall. 

Summary Judgment Order, July 21, 2008, Aplt. App. at 11-12. Sheriff Goering

and his team appear to be primarily responsible for the damage to Mr. Cassady’s

property, as the jury apparently found. DEA Agent Martenson testified at trial, “I

didn’t actually search the residence. It had already been searched.” Aplt. App. at

78. The “local officers” were the ones who searched the house, although “the

DEA m[ight] have helped a little bit, as well.” Id. We do not have the testimony

of other law enforcement officers on this issue due to Mr. Goering’s failure to

provide the full transcript of the trial.

In the related criminal proceeding against Mr. Cassady, the district court –

with a different judge presiding – found the search unlawful and ordered all

evidence obtained from it suppressed. Amended Order Granting Defendant’s

Motion to Suppress, October 23, 2002, Aplt. App. at 6. In that proceeding, the

court held (1) there was no probable cause for the search and seizure; (2) the

search warrant was overbroad and exceeded the scope of probable cause in the

affidavit; and (3) the “good faith” exception did not apply. Id.

In the present civil proceeding from which this appeal was taken, the

district court granted Sheriff Goering qualified immunity with regard to Mr.

Cassady’s arrest, but denied it with regard to the search warrant, holding it

overbroad and its execution unlawful. Following a jury verdict for Mr. Cassady,

Sheriff Goering filed a Rule 50(b) Motion for Judgment as a Matter of Law and
-6-

Renewed Motion Based Upon Qualified Immunity. The district court denied the

motion, reiterating its reasoning in the summary judgment order and concluding

that “the law was clearly established in this circuit that such an overly broad

warrant was unconstitutional” and that “there was a legally sufficient evidentiary

basis for a reasonable jury to find for the jury [sic] on his civil rights claim

against defendant Goering.” Amended Order, February 15, 2007, Aplt. App. at

105-106. The district court noted,

The facts presented to the jury included an overly broad search

warrant, damage done to plaintiff’s property beyond that necessary to

take possession of marijuana plants, damage to areas that were not

involved in the marijuana grow and a tolerance by defendant Goering

of individuals’ access to plaintiff’s property while defendant Goering

was the supervising law enforcement officer on the premises. 

Id. at 106. The district court also determined the jury had arrived at a

compromise verdict and accordingly granted Mr. Cassady’s motion for a new trial

on the § 1983 and trespass claims, a determination not before us.

II.

At issue in this case is Sheriff Goering’s entitlement to qualified immunity

prior to a retrial. Mr. Cassady asserts that Mr. Goering lost or waived his right to

an interlocutory appeal of the denial of qualified immunity. He does not provide

us with authority for this proposition, however. While Mr. Cassady is correct that

“[t]he Supreme Court has repeatedly stressed the importance of resolving the
-7-

qualified immunity question at the earliest possible stage in the litigation[,]”

Aple. Br. at 1, this rule is for the benefit of the party asserting a qualified

immunity defense. See Mitchell v. Forsyth, 472 U.S. 511, 526 (1985) (noting that

one purpose of resolving qualified immunity early in the litigation is “to avoid

subjecting government officials either to the costs of trial or to the burdens of

broad-reaching discovery” (internal quotation marks and alteration omitted));

Saucier v. Katz, 533 U.S. 194, 200 (2001) (“Where the defendant seeks qualified

immunity, a ruling on that issue should be made early in the proceedings so that

the costs and expenses of trial are avoided where the defense is dispositive.”). 

We have never held that a qualified immunity ruling is unreviewable following a

trial, and we have allowed defendants to reassert qualified immunity claims posttrial where there were factual disputes requiring a jury determination. See Maesta

v. Lujan, 351 F.3d 1001, 1008-10 (10th Cir. 2003). Here, Mr. Goering is facing a

retrial and we see no reason why he should be prohibited from appealing the posttrial order rejecting his qualified immunity claim. 

III.

We apply a de novo standard of review to the denial of a summary

judgment motion raising a question of qualified immunity. Gross v. Pirtle, 245

F.3d 1151, 1155 (10th Cir. 2001). “When a defendant raises the qualified

immunity defense on summary judgment, the burden shifts to the plaintiff to meet
-8-

a strict two-part test.” Nelson v. McMullen, 207 F.3d 1202, 1206 (10th Cir.

2000). The plaintiff must show (1) that the defendant violated a constitutional or

statutory right, and (2) that this right was clearly established at the time of the

defendant’s conduct. Gross, 245 F.3d at 1155-156. We review the evidence in

the light most favorable to the nonmoving party. Cortez v. McCauley, 478 F.3d

1108, 1115 (10th Cir. 2007) (en banc). These standards are equally applicable

here, where the district court denied Mr. Goering’s renewed motion as a matter of

law.

Constitutional Violation

The Fourth Amendment provides that “no Warrants shall issue, but upon

probable cause, supported by Oath or affirmation, and particularly describing the

place to be searched, and the persons or things to be seized.” U.S. CONST. amend.

IV. The warrant requirement has at least two distinct purposes: 

First, the magistrate’s scrutiny is intended to eliminate altogether

searches not based on probable cause. The premise here is that any

intrusion in the way of search or seizure is an evil, so that no

intrusion at all is justified without a careful prior determination of

necessity. The second, distinct objective is that those searches

deemed necessary should be as limited as possible. Here, the specific

evil is the ‘general warrant’ abhorred by the colonists, and the

problem is not that of intrusion per se, but of a general, exploratory

rummaging in a person’s belongings. The warrant accomplishes this

second objective by requiring a ‘particular description’ of the things

to be seized.

Coolidge v. New Hampshire, 403 U.S. 443, 467 (1971) (citations omitted). As we

have previously explained, “the fourth amendment requires that the government
2

 We have recognized this rule from Leary as the governing standard for

assessing whether a warrant satisfies the Fourth Amendment’s particularity

requirement. See, e.g., United States v. Riccardi, 405 F.3d 852, 862 (10th Cir.

2005).

-9-

describe the items to be seized with as much specificity as the government’s

knowledge and circumstances allow, and warrants are conclusively invalidated by

their substantial failure to specify as nearly as possible the distinguishing

characteristics of the goods to be seized.” United States v. Leary, 846 F.2d 592,

600 (10th Cir. 1988) (internal quotation marks omitted).2 Thus, the “particularity

requirement” prevents general searches and strictly limits the discretion of the

officer executing the warrant. See Voss v. Bergsgaard, 774 F.2d 402, 404 (10th

Cir. 1985) (“The particularity requirement ensures that a search is confined in

scope to particularly described evidence relating to a specific crime for which

there is demonstrated probable cause.”); see also United States v. Janis Indus., 48

F.3d 1548, 1553 (10th Cir. 1995) (“As to what is to be taken, nothing is left to the

discretion of the officer executing the warrant.” (quoting Stanford v. Texas, 379

U.S. 476, 485 (1965))). 

The warrant here is ungrammatical and difficult to read in many respects. 

It authorized the search of the entire farm, including Mr. Cassady’s house, and the

seizure of “[a]ny & all narcotics,” “[a]ny and all illegal contraband” and various

specific items mostly related to a narcotics operation. See attached Ex. A. In

addition, however, and most damaging to Mr. Goering’s argument, the warrant
3

 Indeed, the affiant did not have any experience in narcotics

investigations, and had never before written a warrant for a drug-related search. 

Compare, e.g., United States v. Wicks, 995 F.2d 964, 967, 973 (search warrant

issued for specific items of records and contraband likely to be found in relation

to drug operation after affiant stated “his experience in investigating drug

(continued...)

-10-

expressly permitted the search and seizure of “all other evidence of criminal

activity” as well as personal property that was stolen, embezzled, or otherwise

illegal; or was designed, intended, or had been used to commit a criminal offense;

or would be material evidence in a criminal prosecution in Colorado or any other

state; or the seizure of which was expressly required, authorized, or permitted by

any Colorado statute. Id. Hence, the warrant did not confine the scope of the

search to any particular crime. The officers only had probable cause to search for

evidence related to marijuana cultivation, yet the warrant authorized the seizure

of all possible evidence of any crime in any jurisdiction. Consequently, “[t]he

warrant[] allowed precisely the kind of rummaging through a person’s belongings,

in search of evidence of even previously unsuspected crimes or of no crime at all,

that the fourth amendment proscribes.” Voss, 774 F.2d at 405.

The affidavit, which was incorporated by reference, does not save the

warrant. See attached Ex. B. The only grounds it provides are Queen’s statement

that he saw marijuana plants on the farm, and Mr. Cassady’s 1992 arrest for a

marijuana-related offense. It makes no mention of the affiant’s training or

expertise in narcotics investigations,3

 and it is no more particular than the

(...continued)

trafficking crimes and enumerated the types of evidence of unlawful activity he

would expect to find . . . based on his training, [and] experience.”) (quotation

marks omitted).

4

 Mr. Goering asserts that we should ignore the warrant’s overbroad

language in part because officers did not look for other evidence of criminal

activity. To the contrary, the DEA agent testified that in addition to searching for

evidence pertaining to the marijuana grow, he was also searching for “[a]ll other

evidence of criminal activity.” Aplt. App. at 76.

-11-

warrant, containing virtually identical language describing the items to be seized.

We cannot accept Mr. Goering’s argument that the officers understood the

language permitting seizure as limited to evidence of marijuana-related activities

only.4

 We have previously invalidated warrants substantially more particularized

than the one at issue here. See Leary, 846 F.2d at 594, 601 (holding

impermissibly overbroad a warrant authorizing search of company offices and

seizure of all records and communications “relating to the purchase, sale and

illegal exportation of materials” in violation of federal export laws); Voss, 774

F.2d at 405 (holding impermissibly overbroad a warrant in tax fraud investigation

authorizing the seizure of all business records). It is not enough that the warrant

makes reference to a particular offense; the warrant must “ensure[] that [the]

search is confined in scope to particularly described evidence relating to a

specific crime for which there is demonstrated probable cause.” Voss, 774 F.2d at

404. As we explained in United States v. Le, 173 F.3d 1258, 1275 (10th Cir.

1999), “[t]he difference between a valid warrant and an overbroad warrant lies in
5

 That the officer drawing up the warrant appeared to use stock language in

no way excuses the warrant’s overbreadth. In fact, it seems the officer took a

form warrant that could be applied to almost any crime and added language but

deleted nothing, thereby creating an extremely broad warrant. 

-12-

whether the government could have phrased the warrant more specifically.” This

is simply not a case where “[i]t is difficult to imagine how the . . . warrant could

have been phrased more specifically.” Id. We conclude that the warrant here –

just as in Leary – is “overbroad in every respect,” as it “contains no limitation on

the scope of the search, [and] it is not as particular as the circumstances would

allow or require. . . .”5

 846 F.2d at 605-06; see also Voss, 774 F.2d at 405

(concluding warrant did not satisfy particularity requirement because “[i]t

authorized government agents to rummage through all of [defendant’s records]

seeking any information pertaining to any federal crime”). Thus, because the

warrant authorizes a general search, it is overbroad and invalid.

Mr. Goering contends “[t]here is no constitutional violation merely because

of words in a warrant where there is no resulting unconstitutional search.” Aplt.

Br. at 21. Even assuming the general rummaging that apparently occurred here

could conceivably be characterized as a “constitutional” search, it is well-settled

that “mere words” in a warrant in and of themselves can violate the Fourth

Amendment. In Groh v. Ramirez, 540 U.S. 551 (2004), the Supreme Court

rejected the argument that a lawfully conducted search could be reasonable under

the Fourth Amendment despite an invalid warrant:
-13-

We have clearly stated that the presumptive rule against

warrantless searches applies with equal force to searches whose only

defect is a lack of particularity in the warrant. . . . The uniformly

applied rule is that a search conducted pursuant to a warrant that fails

to conform to the particularity requirement of the Fourth Amendment

is unconstitutional.

Id. at 559-60 (internal quotation marks and citations omitted). Thus, Mr.

Goering’s attempt to separate the authorization of the search from the execution

of the search is a red herring – a violation of the warrant requirement is itself a

violation of the Fourth Amendment. 

The Supreme Court in Groh explained why an unconstitutional warrant

cannot be saved by a reasonable search: “Even though petitioner acted with

restraint in conducting the search, ‘the inescapable fact is that this restraint was

imposed by the agents themselves, not by a judicial officer.’” Id. at 561 (quoting

Katz v. United States, 389 U.S. 347, 356 (1967)). The Court continued, “We have

long held . . . that the purpose of the particularity requirement is not limited to the

prevention of general searches. A particular warrant also assures the individual

whose property is searched or seized of the lawful authority of the executing

officer, his need to search, and the limits of his power to search.” Id. (internal

citation and quotation marks omitted); see also McDonald v. United States, 335

U.S. 451, 455 (1948) (“We are not dealing with formalities. The presence of a

search warrant serves a high function.”). Again, there were no such limits here:

the warrant permitted officers to search for all evidence of any crime.
-14-

Mr. Goering urges us to apply the severability doctrine, traditionally

applied in the criminal context, whereby the invalid parts of a warrant are severed

from the valid parts and suppression is only required for those items seized

pursuant to the invalid parts. See United States v. Brown, 984 F.2d 1074, 1077

(10th Cir. 1993) (adopting severability doctrine); see also United States v. Sells,

463 F.3d 1148, 1153 (10th Cir. 2006) (applying severability doctrine); United

States v. Naugle, 997 F.2d 819, 822 (10th Cir. 1993) (same). Without providing

any authority for the proposition, Mr. Goering contends the severability doctrine

can be applied to this civil case to “cure” the unlawful parts of the warrant. 

Because we conclude that the severability doctrine would not apply here even if

this appeal were from a criminal suppression hearing, we need not decide whether

the doctrine is applicable in a civil context. The rule in this circuit in criminal

cases is that the severability doctrine is only applicable if “the valid portions of

the warrant [are] sufficiently particularized, distinguishable from the invalid

portions, and make up the greater part of the warrant.” Naugle, 997 F.2d at 822;

see also Sells, 463 F.3d at 1151.

The dissent’s contention that our early cases did not address the “greater

part of the warrant” requirement is a stretch. See Dissent at 3. Brown did address

the limitation at issue here, noting that “although one sentence of the warrant may

have been overbroad, the infirm part may be isolated and severed from the

constitutionally adequate part.” 984 F.2d at 1078. That is precisely the question
-15-

here–whether the warrant is so overbroad that it is functionally impossible to

isolate and sever the acceptable portion. With respect to the severance in Brown,

the crime for which there was probable cause to search was the possession and

prior sale of stolen property. 984 F.2d at 1075-77. The warrant specifically

itemized certain pieces of stolen property and then added “[a]ny other item which

the officers determine or have reasonable belief is stolen while executing this

search warrant.” Id. at 1076. We held the last sentence was overbroad but that

the specified items were searchable. A sentence authorizing a search for all other

items which are stolen is considerably more confined than one authorizing a

search for “all other evidence of criminal activity,” as the warrant in this case

does. In Leary, we noted that “severance is not always possible.” 846 F.2d at

606 n.25 (citation omitted). In so doing, we cited United States v. Christine, 687

F.2d 749, 759 (3d Cir. 1982), for its rule that “all evidence seized pursuant to a

general warrant must be suppressed.” Id.

In Sells, 463 F.3d at 1155-1161, we provided an extensive, multi-step

analysis for determining when the severability doctrine may be applied. After

dividing the warrant into sections, we evaluate the constitutionality of each part. 

See id. at 1155-1157. If at least one part passes constitutional muster (i.e., is

sufficiently particularized and supported by probable cause), we determine

whether the valid sections are distinguishable from the invalid sections. Id. at

1158. As we explained in Sells, “[t]he mere fact that one or more parts of a
6

 

Any & all narcotics, to wit; marijuana plants and/or marijuana,

which is a schedule I controlled substance. Any and all illegal

contraband including, but not limited to; hydroponic grow lights &

meters, watering systems, food, timers, containers, CO2 cylenders

fertalizer [sic], pruning equipment, any & all U.S. currency and/or

(continued...)

-16-

search warrant are valid, however, does not mean that the severance doctrine is

automatically applicable. Instead, . . . some part of the warrant must be both

constitutionally valid and distinguishable from the invalid portions in order for

severability to apply.” Id. (internal quotation marks omitted) (emphasis in

original). Severance is permissible where “each of the categories of items to be

seized describes distinct subject matter in language not linked to language of

other categories, and each valid category retains its significance when isolated

from rest of the warrant.” Id. Notably, this does not end the inquiry, however: 

“[t]otal suppression may still be required even where a part of the warrant is valid

(and distinguishable) if the invalid portions so predominate the warrant that the

warrant in essence authorizes a general, exploratory rummaging in a person’s

belongings.” Id. (internal quotation marks omitted). 

Applying the approach laid out in Sells to the case at hand, we begin by

dividing the warrant into “individual phrases, clauses, paragraphs, or categories

of items.” Id. at 1155. The warrant here can be divided into three general parts:

(1) the section authorizing seizure of narcotics and related illegal contraband;6

 (2)
6

(...continued)

financial instruments, precious metals, jewelery [sic], other items

evidencing the obtaining, secreting, transfer and/or concealment of

assets and the obtaining, secreting, transfer, concealment and/or

expenditure of money, records of transactions, records of plant

growth, books, receipts, notes, ledgers, and other papers relating to

the transportation, ordering, purchasing, and distribution of

controlled substances, in particular a Schedule I controlled

substance, to wit: marijuana. Further, any scales, measuring devices

which indicaye [sic] distribution of controlled substances, and/or

other narcotics. Further, computers, computer generated printouts,

computer programs pertaining to financial transactions and/or

computer discs where computer generated information pertaining to

narcotic information storage for later recovery.

Ex. A (emphasis added).

7

 “And all other evidence of criminal activity.” Ex. A.

8

and [sic] articles of personal property tending to establish the

identity of the person or persons in control or possession of the place

or vehicle, including but not limited to, utility company receipts, rent

receipts, cancelled mail envelopes, vehicle registration, credit card

receipts, repair bills, photographs, keys and articles of clothing,

believed to situated at the place, in the vehicle or on the person

known or described as: Unincorporated Kit Carson County, State of

Colorado; upon one or more of the grounds set forth in the Colorado

Revised Statues and the Colorado Rules of Criminal Procedure,

namely; that this property is stolen or embezzled; or is designed or

intended for use as a means of committing a criminal offense; or is or

has been used as a means of committing a criminal offense; or the

possession of which is illegal; or would be material evidence in a

(continued...)

-17-

the section authorizing seizure of all other evidence of criminal activity;7

 and (3)

the section authorizing seizure of Mr. Cassady’s personal property if its seizure is

authorized on a number of enumerated grounds totally unrelated to a narcotics

operation.8

 Only the first of these sections – directing officers to seize “[a]ny &

seizure of which is expressly required, authorized or permitted by

any statute of this state. 

Ex. A (emphasis added).

-18-

all narcotics, to wit; marijuana plants, and/or marijuana” and illegal contraband

related to marijuana distribution – is arguably valid. And this is true only if we

assume that everything in the sentence beginning, “Any and all illegal contraband

including but not limited to,” is meant to be narrowed by a requirement that the

illegal contraband be related “to the transportation, ordering, purchasing, and

distribution of controlled substances, in particular a Schedule I controlled

substance, to wit: marijuana,” which appears at the end of this convoluted

sentence. See note 6, supra. It is even a greater stretch to narrow the inclusion in

the middle of this long sentence of “any & all U.S. Currency and/or financial

instruments, precious metals, jewelery [sic],” when the phrase preceding the

narrowing clause at the end of the sentence is “and other papers relating to” a

controlled substance. Ex. A (emphasis added). Even assuming we view the

reference to “contraband” narrowly as contraband related to a marijuana

operation, which is supported by the crime for which there was probable cause,

severance would still be improper in this case for the following reasons. Id. 

The second and third sections are clearly invalid. The second section

expressly permits seizure of “all other evidence of criminal activity,” without any
9

 If the dissent’s reading of this section of the warrant is correct and the last

half of this paragraph modifies the entire warrant instead of just the preceding

sentences, see dissent at 10-12, this fact only adds further support to our

conclusion that the warrant cannot be saved. Under the dissent’s reading, officers

not only had permission to search for “any [] evidence of criminal activity,” but

could conduct this search and seizure pursuant to any one of the seven listed

grounds, effectively permitting search for any evidence of any crime in any state. 

We note that the dissent does not point us to any case upholding a warrant with

such language.

-19-

limitation or reference to a specific crime. Id. The third section authorizes

seizure of 

articles of personal property tending to establish the identity of the

person or persons in control or possession of the place or vehicle . . .

[upon the grounds] that this property is stolen or embezzled; or is

designed or intended for use as a means of committing a criminal

offense; or is or has been used as a means of committing a criminal

offense; or the possession of which is illegal; or would be material

evidence in a subsequent criminal prosecution in this state or another

state; or the seizure of which is expressly required, authorized or

permitted by any statute of this state.

Id. (emphasis added).9 Neither section is linked in any way to marijuana

cultivation; instead, both sections appear intended to give officers as few limits as

possible. “Mere reference to ‘evidence’ of a violation of a broad criminal statute

or general criminal activity provides no readily ascertainable guidelines for the

executing officers . . . . As a consequence, authorization to search for ‘evidence

of a crime,’ that is to say, any crime, is so broad as to constitute a general

warrant.” United States v. George, 975 F.2d 72, 75 (2d Cir. 1992) (citations

omitted) (holding warrant authorizing search of “any other evidence relating to
10 The dissent criticizes our grouping of the first 162 words into one part

and the next seven words into a separate part. See dissent at 8. This misses the

point, however: those seven words–“And all other evidence of criminal

activity”–might as well be 162 words, or 1,062 words, or however many words it

would take to describe what “all other evidence of criminal activity” would

consist of. That is, if the warrant had listed all the items possibly subject to

search and seizure under the catchall phrase, the 162-word description of

narcotics and associated contraband would seem “minor” in comparison. In any

event, our conclusion stands regardless of whether the warrant is divided by

paragraphs and categories of items, as we have attempted to do, or into clauses of

approximately equal length, as the dissent urges. See dissent at 9.

11 Mr. Goering’s focus on the items actually seized is misplaced. See Sells,

463 F.3d at 1159 (“The ‘greater part of the warrant’ analysis focuses on the

(continued...)

-20-

the commission of a crime” overbroad). 

In sum, then, the warrant contains one mostly valid and two invalid

sections.10 While the severance analysis does not end with a “mere counting of

provisions,” Sells, 463 F.3d at 1158, the “number of valid versus invalid

provisions is one element in the analysis of which portion makes up the greater

part of the warrant,” id. at 1159 (internal quotation marks omitted).

We next assess whether the valid section is sufficiently distinguishable

from the invalid sections. See id. at 1158. Setting aside the warrant’s significant

grammatical flaws–which make the warrant exceedingly difficult to decipher – the

section we assume to be valid does seem to be distinguishable from the invalid

sections. Nevertheless, the warrant still fails the final step in the analysis, which

requires us to determine whether the warrant’s valid parts comprise a greater part

of the warrant than the invalid parts. See id.11 We apply a “holistic test” and

“evaluate the relative scope and invasiveness of the valid and invalid parts of the

warrant.” Id. at 1160. As we explained in Sells, “[t]his analysis ensures that

severance does not render the Fourth Amendment’s warrant requirement

meaningless.” 463 F.3d at 1151. The dissent’s analysis entirely ignores Sells’

instruction to conduct a holistic analysis, and instead focuses exclusively on

whether the warrant’s valid sections constitute its greater part in the quantitative

sense. As we said in Sells: 

[M]erely counting parts, without any evaluation of the practical

effect of those parts, is an improperly “hypertechnical” interpretation

of the search authorized by the warrant. See Gates, 462 U.S. at 236,

103 S.Ct. 2317. We conclude that it is not an adequate basis by itself

for determining whether a warrant’s invalid parts render a warrant, as

a whole, general, which is the underlying consideration in our

“greater part of the warrant” analysis. A warrant’s invalid portions,

though numerically fewer than the valid portions, may be so broad

and invasive that they contaminate the whole warrant. Conversely,

the invalid portions, though numerically greater than the valid

portions, may qualitatively contribute less than the valid portions to

the overall scope of the authorized search. Common sense indicates

that we must also evaluate the relative scope and invasiveness of the

valid and invalid parts of the warrant. See Voss v. Bergsgaard, 774

F.2d 402, 406 (10th Cir.1985) (declining to employ the severance

doctrine where “[t]he bulk of the warrant’s provisions . . . simply

allow[ed] for the seizure of evidence, whether or not related to tax

fraud, and largely subsume[d] those provisions that would have been

adequate standing alone”) (emphasis added); see also Spilotro, 800

F.2d at 967 (“[T]he cash and keys sought were not related in the

warrant to specific crimes but rather were only a relatively

insignificant part of the sweeping search for evidence of any
-22-

violation of the thirteen statutes [listed in the warrant].”); 2 LaFave,

supra, § 3.7(d) n. 214 (stating that severability is not applicable “if

probable cause existed as to only a few of several items listed, or as

to a few very particularly described items but not as to other items

described in much more general terms ”). Thus, in determining

whether severance applies, we employ a holistic test that examines

the qualitative as well as the quantitative aspects of the valid portions

of the warrant relative to the invalid portions to determine whether

the valid portions “make up the greater part of the warrant.”

Id. at 1160.

Here, the invalid portions of the warrant are sufficiently “broad and

invasive” so as to “contaminate the whole warrant.” Id. at 1151. As in Voss, the

warrant’s invalid provisions “allow for the seizure of evidence, whether or not

related to [marijuana possession and distribution], and largely subsume those

provisions that would have been adequate standing alone.” 774 F.2d at 406. The

warrant epitomizes a general warrant, and the officers treated it as such. See note

4, supra.

Neither Mr. Goering nor the dissent point us to even one case where the

severability doctrine has been applied to a warrant containing such a broad and

invasive provision authorizing a search for and seizure of any and all evidence of

criminal activity which is wholly unrelated to the crime for which there was

probable cause. As we have stressed, severance is not appropriate in every case. 

See Sells, 463 F.3d at 1155; Naugle, 997 F.2d at 822; see also 2 W. LaFave,

Search and Seizure, § 3.7(d) n.214 (4th ed. 2004) (noting severability is improper

where “probable cause existed as to only a few of several items listed, or as to a
12 For examples of courts declining to apply the severability doctrine, see,

e.g., United States v. Kow, 58 F.3d 423, 428 (9th Cir. 1995) (refusing to apply

severability where only one of the categories of items to be seized was not

overbroad); United States v. Spilotro, 800 F.2d 959, 967 (9th Cir. 1986) (refusing

to sever where specifically described items “were only a relatively insignificant

part of the sweeping search for evidence of any violation of the thirteen [criminal]

statutes”); United States v. Patrick, 916 F. Supp. 567, 574 (N.D. W.Va. 1996)

(declining to apply severability doctrine where “valid portion of the warrant is a

relatively insignificant part of an otherwise invalid search”); United States v.

Marcus, 807 F. Supp. 934, 937 (E.D.N.Y. 1992) (declining to sever warrant

because valid portions of warrant “ma[de] up only an insignificant or tangential

part of the warrant”). 

13 See dissent at 3. The question presented in United States v. Soussi, 29

F.3d 565, 572 (10th Cir. 1994), the case on which the dissent relies, was whether

items seized pursuant to an invalid portion of a warrant could be admitted under

the plain view doctrine, an issue not before us.

-23-

more general terms”). In fact, “every court to adopt the severance doctrine has

further limited its application to prohibit severance from saving a warrant that has

been rendered a general warrant by nature of its invalid portions despite

containing some valid portion.” Sells, 463 F.3d at 1158.12 For all of these

reasons, it would be inappropriate to apply the severability doctrine to save the

warrant in this case.

The dissent latches onto one line of dicta from a footnote in a case not

squarely addressing the severability doctrine13 and seeks to overrule the clear rule

of this circuit, established in Naugle and followed in Sells, which provides that

severability is only applicable where “the valid portions of the warrant [are]

sufficiently particularized, distinguishable from the invalid portions, and make up
14 Significantly, Soussi cites Naugle, 997 F.2d at 819, for the proposition

that “we limited somewhat the severability concept to allow it only when at least

a substantial part of the warrant is valid.” Soussi, 29 F.2d at 568 n.3.

-24-

the greater part of the warrant.” Naugle, 997 F.2d at 822; Sells, 463 F.3d at 1150-

51. As an initial matter, we do not see how Soussi’s “at least a substantial part of

the warrant,” Soussi, 29 F.3d at 568 n.3,14 formulation is any less subjective than

the “greater part of the warrant” formulation from Naugle and Sells. Accordingly,

each of the dissent’s criticisms –i.e., that the rule offers few guidelines and that it

is difficult for courts to weigh parts of the warrant against each other, see dissent

at 18-19–would apply equally to the Soussi test. Moreover, the facts of this case

still would not justify application of the severability doctrine even under the test

urged by the dissent because under the long-established rule general warrants

cannot be saved. See Sells, 463 F.3d at 1148 (“[A]lthough articulated in varying

forms, every court to adopt the severance doctrine has further limited its

application to prohibit severance from saving a warrant that has been rendered a

general warrant by nature of its invalid portions despite containing some valid

portion.”). 

The dissent argues that we are creating a per se rule that a warrant

authorizing a search of “all [] evidence of any criminal activity” is an

impermissible general warrant. Dissent at 13. Yet the dissent does not point to a

single case where such expansive language was held not to constitute a general
15 In Brown, the defendant was suspected of motor vehicle theft and the

warrant authorized seizure of specific named items and “any other item which the

Officers determine or have reasonable belief is stolen.” Brown, 984 F.2d at 1076. 

In United States v. LeBron, 729 F.2d 533, 536 (8th Cir. 1984), the defendant was

suspected of purchasing stolen property and the warrant authorized seizure of

certain named items as well as “other property . . . for which there exists probable

cause to believe it to be stolen.”

16 While the warrants in Aday v. Superior Court of Alameda Cty., 362 P.2d

47, 50 (Cal. 1961), and United States v. George, 975 F.2d 72, 74 (2d Cir. 1992),

come closer to the type of general authorization at issue here, those decisions are

in clear conflict with our holding in Naugle and Sells, and so do not change the

result here. Moreover, while the Second Circuit in George recognized the

severance doctrine and stated that warrants “may in appropriate cases be

severed,” it remanded for the district court to decide whether severance was

appropriate in the particular case. 975 F.2d at 79, 80.

warrant. We cannot agree that “[t]he offensive phrase in Mr. Cassady’s warrant

is no more disagreeable than the general authorization to search in Aday or

George, or the general rummaging authorized by the warrants in Brown and

LeBron.” Id. at 17. There is an important distinction to be made between

warrants that have been interpreted to have an overbroad clause because they

contain language permitting search and seizure of any evidence of the specified

crime for which there was probable cause, as in Brown and LeBron,

15 and the

warrant here, which permitted search and seizure of any evidence of any crime.16

This catchall provision permits search for any evidence of any crime, be it

murder, robbery, stolen property, fraud, tax evasion, or child pornography, to

name just a few examples, despite the undisputed fact that there was no probable

cause to believe that Mr. Cassady was involved in any crime other than marijuana
-26-

cultivation. We are unable to see how this would not constitute a general

exploratory warrant. “As an irreducible minimum, a proper warrant must allow

the executing officers to distinguish between items that may and may not be

seized.” Leary, 846 F.2d at 602. Far from leaving nothing to the discretion of the

officer, see Janis Industries, 48 F.3d at 1553, under the warrant here everything

was left to the discretion of the officer.

We have previously applied a blanket suppression where officers conducted

a general search for evidence of crimes not specifically listed in the warrant. 

United States v. Foster, 100 F.3d 846, 851-52 (10th Cir. 1996); United States v.

Medlin, 842 F.2d 1194, 1199-1200 (10th Cir. 1988). Given this line of cases, it

would be an odd result not to suppress warrants that expressly authorize a general

search and seizure. Law enforcement officers could circumvent the prohibition

against general searches (and the consequent remedy of blanket suppression)

simply by inserting a catchall sentence into the warrant itself. 

 Moreover, all evidence was ordered suppressed in the criminal case

against Mr. Cassady; this appeal concerns a civil suit for damages. Although the

dissent acknowledges the rule that severance is only appropriate when “[t]he cost

of suppressing all the evidence seized . . . is so great that the lesser benefits

accruing to the interests served by the Fourth Amendment cannot justify complete

suppression,” Sells, 463 F.3d at 1155 n.3, the dissent fails to identify the social

costs that would result from suppression in this instance, where the criminal case
-27-

was dismissed.

The dissent also neglects to recognize the important Fourth Amendment

interests at stake. Instead, it asserts that “[i]ncluding an overbroad clause []

cannot possibly benefit law enforcement” and seeks to narrow the rationale of the

severability rule’s limitation to only “intentional abuses of the warrant

procedure.” Dissent at 21. The purpose of the Fourth Amendment extends

beyond merely preventing intentional abuses of warrant procedure, however. As

the Supreme Court said in Coolidge, 403 U.S. at 467, “[T]he specific evil is the

‘general warrant’ abhorred by the colonists, and the problem is not that of

intrusion per se, but of a general, exploratory rummaging in a person’s

belongings. The warrant accomplishes this second objective by requiring a

‘particular description’ of the things to be seized.” See also 2 LaFave, Search and

Seizure at § 4.6 (“[T]he primary function of the Fourth Amendment’s

particularity-of-description requirement [is] ensuring that the executing officer

was sufficiently instructed as to what could be searched for and seized under the

warrant.”).

In short, the dissent’s interpretation swallows the rule against general

warrants. The limiting language of the warrant’s first paragraph is entirely

subsumed by the catchall sentence, providing unlimited authorization for search

and seizure of all evidence of any criminal activity.
-28-

Clearly Established Law

Having determined that Sheriff Goering’s actions in authorizing the search

based on the warrant violated Mr. Cassady’s Fourth Amendment rights, we next

ask whether it was clearly established that such conduct was unlawful. See

Cortez, 478 F.3d at 1114 (“The relevant, dispositive inquiry in determining

whether a right is clearly established is whether it would be clear to a reasonable

officer that his conduct was unlawful in the situation.” (quoting Saucier, 533 U.S.

at 202)). In light of our conclusion that the warrant was impermissibly overbroad,

the clearly established prong is easily satisfied. As the Supreme Court made

clear, “Given that the particularity requirement is set forth in the text of the

Constitution, no reasonable officer could believe that a warrant that plainly did

not comply with that requirement was valid.” Groh, 540 U.S. at 563. 

The fact that Sheriff Goering did not personally write the application for

the warrant does not save him: he directed his subordinate to obtain a warrant

and he supervised its execution. See id. at 565 n.9 (“[T]he Fourth Amendment’s

particularity requirement assures the subject of the search that a magistrate has

duly authorized the officer to conduct a search of limited scope. This substantive

right is not protected when the officer fails to take the time to glance at the

authorizing document and detect a glaring defect that . . . is of constitutional

magnitude.”). Mr. Goering’s contention that he could have relied on the

severability doctrine and therefore been shielded by immunity also fails. The
-29-

question is not whether “it was [] clearly established that this technical error

could not be cured by means of a lawful search together with the employment of

the severability doctrine,” Aplt. App. at 96, as he argues, but rather whether it

was clearly established that the warrant violated Mr. Cassady’s constitutional

right to be free from unreasonable searches and seizures. In any event, the

severability cases do not support its application to the warrant here, as explained

above. See Groh, 540 U.S. at 565 (“Absent any support for such an exception in

our cases, [petitioner] cannot reasonably have relied on an expectation that we

would do so.”).

For the foregoing reasons, we AFFIRM the district court’s denial of

qualified immunity to Mr. Goering.

McCONNELL, J., dissenting.

This case involves the difficult question of whether a search warrant

containing some valid and some invalid parts should be severed, so that evidence

seized under the valid parts is permissible. It is undisputed that at least one

clause of the warrant is unconstitutionally overbroad . Although the majority

acknowledges that a substantial portion of the warrant is valid, it concludes that

the invalid sections of the warrant are so “broad and invasive” as to “contaminate

the whole warrant,” making severance inappropriate in this case. Because I

believe the majority’s conclusion follows from a misreading of the warrant and

adds confusion to our severability doctrine, I must respectfully dissent.

I. 

In United States v. Sells, 463 F.3d 1148, 1155 (10th Cir. 2006), we

recognized that “every federal court to consider the issue has adopted the doctrine

of severance, whereby valid portions of a warrant are severed from the invalid

portions and only materials seized under the authority of the valid portions, or

lawfully seized while executing the valid portions, are admissible.” When a

warrant contains both valid and invalid parts, severance is justified because “[t]he

cost of suppressing all the evidence seized, including that seized pursuant to the

valid portions of the warrant, is so great that the lesser benefits accruing to the

interests served by the Fourth Amendment cannot justify complete suppression.”

Sells, 463 F.3d at 155 n.3 (quoting United States v. Christine, 687 F.2d 749, 758
-2-

(3d Cir. 1982)); see also 2 William LaFave, Search and Seizure, § 4.6(f) (4th

ed.2004) (“[I]t would be harsh medicine indeed if a warrant which was issued on

probable cause and which did particularly describe certain items were to be

invalidated in toto merely because the affiant and magistrate erred in seeking and

permitting a search for other items as well.”). 

Of course, severance is not always appropriate. But we have suggested that

severance is usually inapplicable only under certain limited circumstances. First,

severance is obviously unjustified when even after dividing a warrant into

separate clauses or categories, no part of the warrant satisfies the probable cause

and particularity requirements of the Fourth Amendment. In such a case, there is

nothing for severance to save. See Sells, 463 F.3d at 1156 (citing State v.

Maddox, 67 P.3d 1135, 1141 (Wash. App. 2003), aff’d 98 P.3d 1199 (Wash.

2004)). Likewise, severance is inappropriate in a case where the valid portions of

a warrant cannot be linguistically or logically distinguished from the invalid

portions of the warrant. Sells, 463 F.3d at 1158; Christine, 687 F.2d at 754. 

Third, several courts have also held that severance is inappropriate when it is

shown that “the valid parts of the warrant were included by the Government as a

pretext to support an otherwise unlawful search and seizure.” United States v.

Freeman, 685 F.2d 942, 952 (5th Cir. 1982) (internal quotation and citation

omitted); see also Sells, 463 F.3d at 1161 n.7 (reserving question of whether such

a showing would make severance inapplicable). No one has alleged that here. 
1

Contrary to the majority’s assertion, we did not address this exception in

Brown. See Sells, 463 F.3d at 1150–51 (recognizing that this limitation was first

made part of our doctrine in Naugle).

-3-

Finally, like “every [other] court to adopt the severance doctrine,” we have

limited its application to prohibit severance from saving a warrant whose valid

portions are a relatively insignificant portion of the whole. Sells, 463 F.3d at

1158. Only this final limitation is at issue in this case.

We have not always been consistent when describing the contours of this

limitation. See Sells, 463 F.3d at 1158–59. In our earliest cases discussing and

adopting severability, we did not address it at all. See United States v. Leary, 846

F.2d 592, 606 n.25 (10th Cir. 1988); United States v. Brown, 984 F.2d 1074, 1078

(1993)1

. In United States v. Naugle, 997 F.2d 819 (10th Cir. 1993), we suggested

that “[t]o make the severability doctrine applicable the valid portions of the

warrant must . . . make up the greater part of the warrant.” See id. at 822

(emphasis added). We appeared to clarify this statement in United States v.

Soussi, 29 F.3d 565, 568 n.3 (10th Cir. 1994), explaining that severance is

appropriate “only when at least a substantial part of the warrant is valid.” In

Sells, we noted that “[o]ther circuits, seem, for the most part, to follow the Soussi

articulation of the severability test.” Sells, 463 F.3d at 1159. The majority of our

fellow circuits simply ask whether the valid portions of a warrant constitute an

“insignificant or tangential part of the warrant.” Id. at 1160–61; see also Op. 19
-4-

n.9 (describing cases declining to sever, all of which follow this formulation). 

Although we acknowledged that “there may be some nuanced differences among

these various articulations,” we nevertheless followed Naugle’s articulation and

asked whether the valid parts of Mr. Sells’s warrant constituted the “greater part

of the warrant.” Sells, 463 F.3d at 1159–60.

As this case demonstrates, the difference between these various

formulations is not merely semantic. Naugle’s inquiry into whether the valid or

invalid parts of the warrant constitute “the greater part of the warrant” suggests a

comparative analysis under which the proper and improper components of the

warrant are added up, weighed according to their “relative scope and

invasiveness,” id. at 1160, and then cast against each other to determine which

preponderates. In contrast, the formulation suggested by Soussi and followed by

most other circuits dictates a focus on the valid portions of the warrant. So long

as these are substantial, particularized, and distinguishable from the invalid

portions, severance generally would be appropriate, even if the invalid parts of

the warrant were greater in number or significance.

Were we to follow our articulation of the severability test in Soussi, it is

clear that severance would be appropriate in this case. The majority cannot

seriously contest that the valid portions of Mr. Cassady’s warrant—constituting,

even under its analysis, almost the entire set of items described in the first

paragraph—represent substantial parts of the warrant. In the terms employed by
-5-

our sister circuits, the valid portions of the warrant are indisputably not

“insignificant” or “tangential.” See, e.g., United States v. Kow, 58 F.3d 423, 428

(9th Cir.1995); United States v. George, 975 F.2d 72, 80 (2d Cir. 1992); United

States v. Freeman, 685 F.2d 942, 952 (5th Cir. 1982). The majority, however,

employs the Naugle test, and concludes that severance is inappropriate because it

finds that the valid components of the warrant do not constitute the “greater part

of the warrant.”

In the following sections, I explain why even under our Naugle

formulation, the valid parts of the warrant in this case constitute “the greater part

of the warrant,” such that severance is appropriate. In Part III, however, I write

separately to suggest that the Naugle articulation of the severability test disserves

the purpose of severability, and suggest that we should adopt the formulation of

the test stated in Soussi and applied by our sister circuits.

II.

A.

Under our precedent, the first step in determining whether severability

doctrine is applicable is “to divide the warrant into individual phrases, clauses,

paragraphs, or categories of items.” Sells, 463 F.3d at 1155. The manner in

which a warrant is divided will necessarily inform the calculation of whether its

valid parts constitute the “greater part of the warrant.” Although we have

cautioned that a strictly numerical comparison of the valid versus invalid portions
-6-

of a warrant should never be dispositive, we have nevertheless maintained that

“the number of valid versus invalid provisions is one element in the analysis of

which portion makes up the greater part of the warrant.” Op. at 18 (quoting Sells,

463 F.3d at 1155). As a practical matter, the more valid parts of a warrant that

are identified during the partition process, the more likely it is that they will

constitute “the greater part of the warrant.” 

While the precise level of generality at which warrant components are

grouped into categories will vary, often depending on the scope of the items

included in the warrant, the touchstone of the partition process is the division of a

warrant into comparable pieces in terms of the structure of the warrant itself,

typically organized around items or thematically cohesive groups of items (or

locations) to be searched. 

 Thus, in Sells, we divided a warrant authorizing a search for “[a]ny .223

caliber Firearm or rifle, .223 caliber ammunition, footwear, clothing, any other

related fruits, instrumentalities and evidence of the crime” into five categories:

(1) any .223 caliber Firearm or rifle, (2) .223 caliber ammunition, (3) footwear,

(4) clothing, and (5) any other related fruits, instrumentalities and evidence of the

crime. Id. at 1156. Likewise, in Naugle, 997 F.2d at 820–21, while the more

expansive set of items included in the search warrant necessitated larger

categories, we again divided the warrant into four relatively proportionate

groupings: 
2

The actual language of the warrant was as follows:

Letters, papers, documents, checks or envelopes inscribed or printed upon with

the Utah County Constable, the Utah County Constable Star, or any such insignia

which gives the appearance or represents a government agency, or anything else

that in its nature could be used to imply an affiliation with such an agency, any

surveillance equipment including electronic listening and recording devices,

cameras, binoculars, radios, telephone hardware and records, business records,

personnel files, payroll records, computer, both hard and software, contracts,

tapes or video equipment, and any other articles used in the support or furtherance

of. Naugle, 997 F.2d at 820 n.1.

-7-

(1) letters, papers, documents, checks or envelopes inscribed or

printed upon with the Utah County Constable or Utah County

Constable Star; (2) letters, papers, documents, checks or envelopes

inscribed or printed upon any such insignia which gives the

appearance or represents a government agency, or anything else that

in its nature could be used to imply an affiliation with such an

agency; (3) any surveillance equipment including electronic listening

and recording devices, cameras, binoculars, radios, telephone

hardware and records; (4) business records, personnel files, payroll

records, computer, both hard and software, contracts, tapes or video

equipment. Id. at 820.2

In comparison, in this case, the majority divides the warrant into three

wholly disproportionate sections. Although the warrant authorizes the search of

substantially more items than in Sells or Naugle, the majority divides the warrant

into only three sections. But more important than the paucity of categories is the

disproportionality of their content. The three categories could not be more

different in size or scope. Into the first category, the majority lumps the vast

majority of items to be searched for under the warrant, including marijuana, the

materials commonly used to grow it, the financial instruments commonly used to
-8-

obtain drugs and hide proceeds, the scales commonly used to weigh drugs, and the

physical and computer records which commonly detail the purchase and sale of

drugs. Every one of the items that the majority ultimately assumes to be validly

identified has been grouped into one single category, with predictable results for

the majority’s later inquiry as to whether the greater number of the categories in

the warrant is valid or invalid. See Op. 18–20. The majority points to no other

case applying severability doctrine in which so extensive a set of items to be

searched are consolidated into one category for purposes of severability analysis.

While the majority creates its first category out of the first 162 words of the

warrant’s authorization to search, it forms the second category out of the next

seven: “And all other evidence of criminal activity.” The majority then combines

the next two paragraphs into a final category, despite the fact that—as I will later

explain—the two paragraphs serve entirely different purposes in the scheme of

the warrant.

I fully recognize that the process of dividing a warrant has an element of

subjectivity. Reasonable minds will frequently disagree on the best way to

partition the various phrases that make up a warrant, and courts should have

latitude to divide a warrant as best fits the facts of a given case. This a good

reason to adopt a different methodology, as I discuss in Part III. But if we are to

apply the comparative approach of Naugle, we need some way to divide the

warrant into valid and invalid parts and to quantify which is “the greater part.” 
-9-

Our precedents employing this approach show that warrants are to be partitioned

in a commonsensical and consistent manner. While courts are free to divide

warrants into “individual phrases, clauses, paragraphs, or categories of items,”

Sells, 463 F.3d at 1155, it is not commonsensical to divide a warrant into

substantially disproportionate segments. Nor is it appropriate to partition a

warrant primarily with an eye towards different components’ relative propriety or

impropriety. Our precedents make clear that the proper place to “evaluate the

relative scope and invasiveness of the valid and invalid parts of the warrant” is

after the warrant is partitioned into different pieces. See Sells, 463 F.3d at 1160. 

To lump all valid clauses into one category, and to divide invalid clauses into

more than one, is to doom all warrants to nonseverability. 

On analogy to our analysis of the warrants in Sells and Naugle, I would

divide the warrant in this case into at least eight groups of items for which a

search is authorized: 1) narcotics; 2) contraband related to the production of

narcotics; 3) currency or other financial instruments used to obtain or conceal

narcotics; 4) paper records relating to the obtainment or distribution of narcotics;

5) scales or measuring devices used to distribute narcotics; 6) computer records

relating to obtaining or distributing narcotics; 7) all other evidence of criminal

activity; and 8) articles of personal property tending to establish the identity of

the person in control of the place to be searched. Only one of these categories is

improper: the clause authorizing a search for “all other evidence of criminal
3

We have approved searches for substantially similar items to those

described in the first six categories in other drug-related cases: See, e.g., United

States v. Sullivan, 919 F.2d 1403, 1424 and n.31 (10th Cir. 1990) (upholding

warrant for drugs and list of contraband related to the production of drugs);

United States v. Harris, 903 F.2d 770, 774–75 (10th Cir. 1990) (upholding

warrant against marijuana trafficker for “currency . . . stocks, bonds or other

securities . . . gold silver and/or jewelry . . . books, records, memorandum, notes,

bank records, investment records, or any other documents evidencing the

obtaining, secreting, transfer, and/or concealment of assets and/or money obtained

through illegal means”); United States v. Wicks, 995 F.2d 964, 967, 973–74 (10th

Cir. 1993) (upholding warrant for books, records, receipts, notes, ledgers, and

other papers relating to the transportation, ordering, sale and distribution of

controlled substances); id. (upholding warrant for scales); United States v.

Gunderman, 51 F.3d 287 (Table), 1995 WL 143143 at *3 and n.2 (10th Cir. 1995)

(upholding warrant for “[i]tems associated with the processing of controlled

substances for transportation and distribution, such as . . . measuring instruments

and scales”); United States v. Welch, 291 Fed. App’x 193, 203 (10th Cir. 2008)

(noting that a search for computer records connected to the manufacture of

methamphetamine and would not be overbroad).

Likewise, we have frequently approved searches for the last category of

items to be searched, encompassing articles of personal property that establish the

identity of the person in control of the property. See infra at 12.

activity.”3

 When the warrant is more sensibly and consistently divided, it is clear

that the legitimate parts of the warrant outnumber and outweigh the illegitimate.

B.

Even aside from the majority’s seemingly arbitrary division of the warrant

into three disproportionate parts, I believe its interpretation of the “third section”

of the warrant, see Op. 16 n.8, is almost certainly mistaken. The third section, as

identified by the majority, authorizes a search for:

articles of personal property tending to establish the identity of the

person or persons in control or possession of the place or vehicle,

including but not limited to, utility company receipts, rent receipts,
-11-

cancelled mail envelopes, vehicle registration, credit card receipts,

repair bills, photographs, keys and articles of clothing, believed to

situated at the place, in the vehicle or on the person known or

described as: 

Unincorporated Kit Carson County, State of Colorado; upon one or

more of the grounds set forth in the Colorado Revised Statues and the

Colorado Rules of Criminal Procedure, namely; that this property is

stolen or embezzled; or is designed or intended for use as a means of

committing a criminal offense; or is or has been used as a means of

committing a criminal offense; or the possession of which is illegal;

or would be material evidence in a subsequent criminal prosecution

in this state or another state; or the seizure of which is expressly

required, authorized or permitted by any statute of this state. Ex. A.

The majority understands the second paragraph of this section to expand

the scope of the search authorized by the warrant, so as to permit a general search

for any of the kinds of items listed in the second paragraph. See Op. 9. But the

better understanding of the last paragraph is that it simply identifies the grounds

upon which a search is authorized under Colorado law, rather than being an

authorization to search for additional items. Although the warrant is admittedly

“ungrammatical and difficult to read in many respects,” Op. 9, the warrant’s

text—read from start to finish—confirms this reading of the paragraph’s purpose. 

The warrant reads: “The affiant; Willis E. Boden, has filed an Affidavit for a

Search Warrant . . . for the following described property . . . [the list of items to

be searched for] . . . upon one or more of the grounds set forth in the Colorado

Revised Statues and the Colorado Rules of Criminal Procedure, namely . . . [the

list of grounds upon which a search may be legally authorized under Colorado
4

The majority misreads my interpretation of the third section as affording

the police permission to search for any evidence that matches any of the grounds

for which searches are authorized under Colorado law. That is not the case. The

warrant is limited to the items specified; this paragraph merely states the legal

justification. 

-12-

law]”. Ex. A (emphasis added). 

This interpretation of the final paragraph is further supported by the fact

that the six “grounds” articulated in the warrant precisely match the first six

“Grounds for Issuance” for a search warrant under Colorado law. See Colo. Rev.

Stat. 16-3-301; Colo. R. Crim. P. 41(b)(1–6) (providing that a search warrant may

be issued under this Rule to search for any property on the basis of the exact six

grounds listed in Mr. Cassady’s warrant). Consequently, it is clear that the final

paragraph does nothing to expand the scope of the search of the warrant, but

simply identifies the legal grounds upon which a search may be authorized.4

As for the remainder of this part of the warrant, entitling the police officers

to search for “articles of personal property tending to establish the identity of the

person or persons in control or possession of [Mr. Cassady’s] place,” we have

approved similar language on numerous occasions. See United States v. Burns,

624 F.2d 95, 101 (10th Cir. 1980) (approving particularity of a search warrant

designed to uncover “personal property tending to establish the identity of

persons in control of contraband,” and “related paraphernalia consisting in part

and including, but not limited to utility company receipts, rent receipts, cancelled
-13-

mail envelopes, photographs and keys.”); United States v. Baker, 166 F.3d 348

(Table Opinion), 1998 WL 808392 at *4 (10th Cir. Nov. 20, 1998) (finding the

particularity requirement satisfied where the warrant authorized seizure of

“articles of personal property tending to establish the identity of the person or

persons in control or possession of the place or vehicle, including, but not limited

to, utility company receipts, rent receipts, canceled mail envelopes, vehicle

registration, credit card receipts, repair bills, photographs, keys, and articles of

clothing[.]”) Indeed, it is well-established that “[a] search warrant may be used,

not only to gather evidence of a criminal activity, but also to gather evidence of

who controlled the premises suspected of connection with criminal acts.” United

States v. McLaughlin, 851 F.2d 283, 286 (9th Cir. 1988). 

Properly understood, therefore, the majority’s “third section” of the warrant

does not offend the Fourth Amendment. 

C.

The only overbroad language in Mr. Cassady’s warrant is the clause

purporting to authorize a search for “all other evidence of criminal activity.” It is

undisputed that this clause does not satisfy the particularity requirement of the

Fourth Amendment. But as it is the only portion of a lengthy and mostly valid

warrant that fails to pass muster, I would find that the valid parts of Mr.

Cassady’s warrant constitute “the greater part of the warrant.”

To allow the presence of this admittedly overbroad phrase to “contaminate
-14-

the whole warrant,” Op. 18, would be to create a per se rule that the presence of

broad catchall language within an otherwise valid warrant always invalidates the

warrant in full, no matter how detailed and numerous the valid components of the

warrant may be. Indeed, the majority admits as much. See Op. 20 n.10

(suggesting that the overbroad phrase in Mr. Cassady’s warrant would make up

the greater part of the warrant regardless of the character and extent of a

warrant’s valid components). This would be contrary both to the historical

application and purpose of severability doctrine. 

Numerous courts and commentators have recognized the leading case on

severability doctrine to be Aday v. Superior Court of Alameda Cty., 362 P.2d 47

(Cal. 1961). See, e.g., United States v. Riggs, 690 F.2d 298, 300–01 (1st Cir.

1982); Freeman, 685 F.2d at 952; Christine, 687 F.2d at 754 n.4; 2 LaFave,

Search and Seizure at § 4.6(f). In Aday, a police officer obtained a warrant to

search a publisher accused of conspiring to publish, print, and sell lewd books. 

Although the warrant authorized a search for various items in a manner

comporting with Fourth Amendment requirements, it also authorized a search for

“‘any and all other records and paraphernalia connected with’ the business of the

corporate petitioners.” Aday, 362 P.2d at 50 (quoting warrant). Although the

court concluded that this and other overbroad categories “were so sweeping as to

include virtually all personal business property on the premises and placed no

meaningful restriction on the things to be seized,” making it “similar to the
-15-

general warrant permitting unlimited search, which has long been condemned,” it

nevertheless still found the warrant to be severable. Id. at 51–52 (emphasis

added). The court explicitly found that the warrants’ defects did not turn the

warrant into one “essentially general in character but as to minor items,” despite

the fact that part of the warrant provided effectively limitless authorization to

search. Id. at 52.

We have ourselves previously approved of severance in a case where the

bulk of items to be searched were described with particularity, but the warrant

authorized a search for “[a]ny other item which the Officers determine or have

reasonable belief is stolen while executing search warrant.” United States v.

Brown, 984 F.2d 1074 (10th Cir. 1993). In a case we cited with approval in

Brown, the Eighth Circuit concluded that a substantially similar phrase

“provide[d] no protection against subjecting a person’s lawfully held property to a

general search and seizure,” finding that “[s]uch a general authorization allows

officers to search indiscriminately throughout one’s house and to seize anything

they please.” United States v. LeBron, 729 F.2d 533, 537 (8th Cir. 1984). Yet

despite the fact that the overbroad phrases in these warrants effectively authorized

a general rummaging, severance was deemed appropriate in both cases. 

Perhaps the closest case to this one is United States v. George, 975 F.2d 72

(2d Cir. 1992). In that case, the warrant authorized a search for several items

described with particularity, as well as for “any other evidence relating to the
5

The majority notes that in George, the Second Circuit “remanded for the

district court to decide whether severance was appropriate” in that case. Op. 25

n.16. Although it is technically true that the case was remanded because the

district court had not ruled on severance in the first instance, the Second Circuit’s

language in George made clear that the inclusion of overbroad language

authorizing a search for “other evidence relating to the commission of a crime”

did not preclude the application of severance. 

-16-

commission of a crime.” Id. at 74. Although the court recognized that this

overbroad phrase “effectively granted the executing officers virtually unfettered

discretion to seize anything they saw,” id. at 75 (quotation omitted), it found

severance appropriate. In language equally applicable to our own case, the court

concluded that “[w]e have before us on this appeal a warrant that is, in part, so

broad as to be a general warrant and which, as to that part, no reasonable police

officer could suppose otherwise. Yet, we think the warrant in this particular case

may be saved . . . under the doctrine of severance.” Id. at 74. The majority’s

decision thus creates a circuit court conflict where none had existed before.5

The majority attempts to distinguish some of these cases on the ground that

the overbroad language in those cases is not precisely the same as the overbroad

language in Mr. Cassady’s warrant. But this misses the mark. The crucial point

is that other courts have often concluded that severance is appropriate even when

the overbroad portion of the warrant authorizes a general search and seizure—the

precise scenario before us here. And the overbroad language in George is

virtually identical to that in Mr. Cassady’s warrant.
-17-

The majority’s citation to United States v. Foster, 100 F.3d 846, 851–52

(10th Cir. 1996), and United States v. Medlin, 842 F.2d 1194, 1199–1200 (10th

Cir. 1988) (Medlin II) is inapposite. In those cases, we ordered the general

suppression of evidence when the officers executing the warrant exhibited

“flagrant disregard” for its terms, “grossly exceed[ing] the scope” of the search

approved by the neutral magistrate. Medlin, 842 F.2d at 1199; see also Foster,

100 F.3d at 850–51 (noting that the officer admitted that it was “standard

practice” in his county when executing search warrant to “[take] anything of

value” and deliberately disregard the warrant “in an effort to uncover evidence of

additional wrongdoing”). Such cases raise the inference that the warrant obtained

is merely a pretext for a general search—a textbook case for when severance is

inappropriate. See infra at 2. By contrast, total suppression is unnecessary where,

as here, the police search pursuant to a warrant duly submitted to a magistrate in

good faith.

The offensive phrase in Mr. Cassady’s warrant is no more disagreeable than

the general authorization to search in Aday or George, or the general rummaging

authorized by the warrants in Brown and LeBron. As in those cases, I would

conclude that severance best promotes the policies of the Fourth Amendment, by

excluding any evidence obtained pursuant to constitutionally infirm portions of
6

The majority suggests that the social cost of suppressing all evidence

seized in this particular case is diminished because the criminal case against Mr.

Cassady has been dismissed. While the particular case before us is civil in

nature, the majority would apply its rule in all cases—civil or criminal.

the warrant while at the same time avoiding the substantial social costs6

 that

would follow from excluding evidence of criminal activity obtained on the basis

of a warrant’s valid components.

III.

It is not necessary to reconsider our adherence to Naugle’s “greater part of

the warrant” language in order to conclude that severance is appropriate here, but

this case illustrates the shortcomings of our existing approach. In addition to

being difficult to apply, Naugle’s “greater part of the warrant” test departs

unnecessarily, and arguably accidentally, from the test employed in the vast

majority of other jurisdictions. Moreover, the purposes of severability doctrine

are better served by the test employed by our sibling circuits.

First, the subjectivity inherent in applying the “greater part of the warrant”

test leads to unpredictable results. There are few guidelines for courts to follow

when comparing the valid and invalid components of a warrant. Does an

overbroad search for “all evidence of criminal activity” make up the greater part

of a warrant when compared to two valid categories of items? Five? Ten? Does

it matter for purposes of this analysis whether those categories are composed of

single items, like the .223 caliber ammunition in Sells, or of multiple items as in
-19-

Naugle? As this case shows, the manner in which judges chop up a warrant will

often have outcome-determinative effects. 

If there were a sound reason for making the outcome of these cases turn on

whether or not the valid parts of the warrant constituted its “greater part,” then

our test might be defensible, despite the difficulty of its application. But we have

differed from our fellow circuits with little analysis or explanation. Indeed, it is

unclear whether this court actually intended to diverge from the rule followed by

most other circuits. In Naugle, we cited United States v. George, 975 F.2d 72,

79–80 (2d Cir. 1992), for the proposition that “[t]o make the severability doctrine

applicable the valid portions of the warrant must . . . make up the greater part of

the warrant.” Naugle, 997 F.2d at 822. But the words “greater part of the

warrant” appear nowhere in George. Instead, George follows the majority rule

that we seem to have eschewed, explaining that severance “is not available . . .

where the sufficiently particularized portions make up only an insignificant or

tangential part of the warrant.” George, 975 F.2d at 79–80 (emphasis added). 

Thus, it is unclear that our departure from the framework followed by other

jurisdictions was deliberate. Later, in Soussi, we interpreted the limitation only to

make severability inappropriate when the valid portions of the warrant were

insubstantial. See Soussi, 29 F.3d at 568 n.3. 

Most importantly, the purposes of severability doctrine are better served by

following our Soussi articulation. When a warrant contains both valid and invalid
-20-

parts, severance is the favored remedy because it best balances the competing

interests at stake in these cases: deterring the government from searching pursuant

to warrants which fail to satisfy the probable cause or particularity requirements

of the Fourth Amendment and minimizing the social costs that would follow from

the total suppression of validly seized evidence because of defects elsewhere in

the warrant. When the valid parts of the warrant are distinguishable and not

insignificant, these interests are better promoted by severing the warrant—even

when they do not constitute “the greater part of the warrant.” 

Severance in a case like this provides no greater incentive to the police to

search in a manner inconsistent with the Fourth Amendment. Not one piece of

evidence obtained only on the basis of the warrant’s authorization to search for

“all evidence of criminal activity” may be used against Mr. Cassady. Including

an overbroad clause thus cannot possibly benefit law enforcement. Moreover,

officers will not be able to obtain qualified immunity for damages stemming from

those aspects of the search conducted on the basis of components of the warrant

that “no reasonable officer” could have believed to be lawful. See Op. 20

(quoting Groh v. Ramirez, 540 U.S. 551, 563 (2004)). This additional deterrent

will dissuade any impulse to purposefully disregard the Fourth Amendment. As a

result, “the same objectives of deterrence and integrity may be served in the same

way and to the same degree by limiting suppression to the fruits of the warrant’s

unconstitutional component,” irrespective of how broad and invasive the flawed
-21-

components of a warrant may be. 2 LaFave, Search and Seizure at § 4.6(f). On

the other hand, severance here avoids the social costs that would follow from

excluding all of the valid evidence of criminal activity in this case, obtained on

the basis of components of the warrant that the majority concedes are valid.

The purpose of making severance inapplicable in cases where the valid

parts of the warrant make up an insignificant or tangential part of the warrant is to

protect against intentional abuses of the warrant procedure. The limitation is

designed to prevent law enforcement from obtaining essentially general warrants

that happen to pass constitutional muster as to an occasional or minor item in the

scope of the warrant. See Aday, 362 P.2d at 52 (“We recognize the danger that

warrants might be obtained which are essentially general in character but as to

minor items meet the requirement of particularity, and that wholesale seizures

might be made under them, in the expectation that the seizure would in any event

be upheld as to the property specified. Such an abuse of the warrant procedure,

of course, could not be tolerated.”); United States v. Spilotro, 800 F.2d 959, 967

(9th Cir. 1986) (finding that “keys” and “cash” sought under warrant were “only a

relatively insignificant part of the sweeping search for evidence of any violation

of . . . thirteen statutes,” including a long laundry list of invalidly described

items, and therefore were “not sufficiently separable from the rest of the warrant

to allow severance”).

That inference is no longer warranted where, as here, substantial and
-22-

distinguishable parts of the warrant describe items with particularity for which

there is probable cause to justify a search or seizure. Accordingly, I would

conclude that we should reconsider our adherence to Naugle. 

In any event, because even under our existing precedent the valid portions

of Mr. Cassady’s warrant constitute “the greater part of the warrant,” I would

conclude that severance is appropriate. As a result, I would reverse the district

court’s determination that qualified immunity was inappropriate, at least as to

damages alleged to have resulted from aspects of the search following from the

execution of the valid parts of Mr. Cassady’s warrant.
