SUMMARY OF ARGUMENT 
The district court enjoined the application of a critical public-health 
measure—the authority granted in Section 265 to prevent the introduction of a 
communicable disease into the United States.  The challenged U.S. Centers for 
Disease Control and Prevention (CDC) Order protects against the risk of 
transmission of COVID-19 resulting from holding noncitizens in congregate 
settings—facilities that are not designed or equipped to quarantine, isolate, or 
enable social distancing—pending immigration processing.  If permitted to go into 
effect, the district court’s injunction would prohibit the U.S. Government from 
exercising the authority to expel noncitizens who come to the United States as a 
family unit.  The government would instead be required to hold those noncitizens 
in congregate settings at or near the border, thereby exacerbating the virus-
transmission risk.  The preliminary injunction would preclude the government 
from exercising its lawful discretion under Section 265 to respond in an 
appropriate and measured manner to a serious public-health threat from a deadly 
communicable disease.  The highly transmissible Delta variant and the historic 
surge of noncitizens crossing the Southwest Border have only increased the need 
for the Order.   
Plaintiffs’ opposition fails to undermine the government’s demonstration 
that the district court abused its discretion.  On the merits, the statutory text and 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 6 of 35

2 
 
context strongly support CDC’s conclusion that Section 265 authorizes 
enforcement of the prohibition on introduction of noncitizens by expelling those 
noncitizens if they manage to cross the border before being encountered.  Plaintiffs 
fall back on alternative merits arguments that Section 265 regulates only 
transportation providers; that CDC’s interpretation impermissibly overrides certain 
immigration statutes; and that CDC’s interpretation would raise constitutional 
concerns if applied to U.S. citizens.  But the district court did not reach or rule 
upon any of those arguments, and this Court should likewise decline to affirm the 
district court’s injunction on these grounds.  In any event, the arguments are 
meritless.   
First, plaintiffs’ contention that Section 265 authorizes only the regulation of 
transportation providers impermissibly transforms a broad grant of statutory 
authority to address the serious threat of communicable disease into a limited 
authority that would leave the agency powerless to prohibit the spread of disease 
by those crossing a land border without the assistance of a transportation company.  
Second, Section 265 does not irreconcilably conflict with the immigration 
provisions that plaintiffs invoke.  Those generally applicable immigration 
provisions apply in normally prevailing conditions in the absence of a rare public-
health emergency, whereas Section 265 applies only in narrow and specific 
circumstances of a public-health emergency.  And even if there were a conflict, 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 7 of 35

3 
 
Section 265 would control.  Third, this Court does not need to address plaintiffs’ 
argument that CDC’s interpretation would raise constitutional concerns if applied 
to U.S. citizens, as neither the final rule nor the CDC Order applies to U.S. 
citizens.  At a minimum, CDC’s reasonable interpretation is entitled to Chevron 
deference.   
Plaintiffs have also failed to demonstrate that the remaining preliminary 
injunction factors support an injunction.  The COVID-19 pandemic continues to be 
a highly dynamic public-health emergency.  CDC’s discretion concerning whether 
to prohibit the introduction of persons from particular countries and in what 
circumstances is critical to avoiding irreparable harm.  Plaintiffs ask this Court to 
overrule CDC’s expert public-health judgment regarding the increased risk of a 
serious danger of transmission of COVID-19.  But Congress charged CDC—not 
the federal courts—with making public-health judgments about how best to protect 
the country during a pandemic.   
ARGUMENT 
I. 
The Government is Likely to Succeed on the Merits 
A. 
Prohibiting the “Introduction” of Persons from a Foreign 
Country with a Serious Danger of Communicable Disease 
Includes the Authority to Expel Such Persons 
Section 265 authorizes CDC “to prohibit, in whole or in part, the 
introduction of persons and property” from a foreign country “[w]henever” the 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 8 of 35

4 
 
agency “determines” that, “by reason of the existence of any communicable 
disease in a foreign country,” the “introduction of persons or property from such 
country” presents a “serious danger of the introduction of such disease into the 
United States,” and the prohibition “is required in the interest of the public health.”  
42 U.S.C. § 265.  Plaintiffs and the district court are incorrect in concluding that 
this statutory authority does not provide CDC with any authority to expel persons 
from the United States once they cross the border. 
As a matter of ordinary language, the power to prohibit something naturally 
encompasses the power to stop the prohibited action after it has begun or to 
remedy a violation that evades the statutory prohibition.  A statute prohibiting 
persons from entering certain areas is most naturally read to include both the power 
to prevent persons from entering in the first instance and the power to expel them if 
they mistakenly or surreptitiously enter in contravention of that prohibition.  See 
Gov’t Br. 27-32.  Thus, “prohibit[ing]” the “introduction” of a person who may 
carry a communicable disease into the United States and to the population at large 
encompasses turning noncitizens around and sending them back across the border 
if they mistakenly or surreptitiously enter in contravention of that prohibition, in 
order “to avert [the] danger” of “the introduction of [communicable] disease into 
the United States.”  42 U.S.C. § 265.   
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 9 of 35

5 
 
Statutory context also squarely supports CDC’s interpretation.  Section 265 
seeks “to avert” the “serious danger of the introduction * * * into the United 
States” of “any communicable disease in a foreign country” if that “danger is so 
increased by the introduction of persons * * * from such country.”  The need to 
prevent the spread of disease is in no way diminished by the fact that a noncitizen 
has arrived at a Port of Entry or managed to cross the border unlawfully, and 
neither plaintiffs nor the district court offer any plausible reason why the statute 
should be read to render CDC powerless in those circumstances.   
Plaintiffs argue that the statute could confer expulsion authority only if 
Congress explicitly authorized physical removal with an “express statement” or 
included catch-all language such as take “other appropriate action” or “other 
measures.”  Br. 16-20.  What matters is not whether Congress used magic words, 
but what the words that Congress did use mean.  Here, the most common-sense 
reading of Section 265 includes the power both to prevent persons from entering 
and to prevent people who manage to evade restrictions on entering from moving 
further into the country by expelling them. 
Plaintiffs rely on extradition statutes in arguing that Congress has a “long 
history” of expressly granting expulsion authority.  Br. 17.  But it is not surprising 
that extradition statutes use terms such as “return[] and surrender[],” 18 U.S.C. 
§ 3185, as the definition of “extradite” is “[t]o surrender or deliver (a fugitive) to 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 10 of 35

6 
 
another jurisdiction” or “to send (an accused person) back to the state or country 
where a crime may have happened,” Extradite, Black’s Law Dictionary, Westlaw 
(11th ed. 2019).  Plaintiffs rely on Valentine v. United States ex rel. Neidecker, 299 
U.S. 5 (1936), but that case addressed whether a treaty authorized the extradition 
of U.S. citizens where the treaty stated that “[n]either of the contracting Parties 
shall be bound to deliver up its own citizens.”  Id. at 6-7.  The Court held that “a 
grant * * * of discretionary power to surrender citizens of the United States” may 
not “be implied” from this language.  Id. at 11-12.  Valentine thus has no bearing 
on the meaning of Section 265, particularly where the final rule and the CDC 
Order do not apply to U.S. citizens.  42 C.F.R. § 71.40(f); 1 Joint Appendix (JA) 
148.   
Plaintiffs also find it significant (Br. 17) that in 1893, Congress 
simultaneously considered two competing bills to address the cholera epidemic—
the bill that would become Section 265, and a competing bill (that Congress did 
not enact) that would have suspended all immigration for one year and that 
specified that an immigrant entering to the contrary shall “be sent back to the 
country from which he came.”  24 Cong. Rec. 290 (1892).  But in debating the 
merits of these competing bills, no member of Congress attributed any significance 
to the absence of similar language in Section 265.  Rather, Senators discussed the 
merits of requiring a presidential proclamation to trigger a prohibition (as Section 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 11 of 35

7 
 
265 required, but the competing bill did not), see 24 Cong. Rec. 364-65 (1893), 
and the merits of applying a prohibition to immigration only (as the competing bill 
did, see 24 Cong. Rec. 290) or also to tourists and other temporary visitors (as did 
Section 265, as amended), see 24 Cong. Rec. 361, 363, 374.  And Senator 
Chandler, who introduced and was the chief proponent of the competing bill, 
ultimately proclaimed himself “heartily in favor” of Section 265, 24 Cong. Rec. 
393, voted for Section 265 as amended, id. at 471, and let his competing bill 
“lapse,” id. at 473.  To the extent the legislative history of this unenacted bill is 
relevant, it demonstrates that no member of Congress viewed the absence of “sent 
back” language in Section 265 to be a notable difference, consistent with the view 
that Section 265’s language is most naturally read to include the authority to 
prohibit entry as well as to expel. 
Plaintiffs note that under certain immigration provisions, the government 
can detain and remove noncitizens on “health-related grounds.”  Br. 18 (citing 
8 U.S.C. §§ 1182(a)(1), 1222).  That Congress separately addressed health-related 
grounds of inadmissibility in an immigration statute says nothing about the 
meaning of Section 265, a public-health statute.  If anything, the fact that Congress 
enacted Section 265 to address the cholera epidemic just two years after enacting a 
statute to exclude noncitizens from admission because of a “dangerous contagious 
disease,” 26 Stat. 1084, 1084 (1891); see Br. 18, underscores that Congress 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 12 of 35

8 
 
considered the existing immigration laws insufficient to address adequately the 
relevant dangers, and that Congress intended for Section 265 to confer a greater 
authority to prohibit the entry of, and to expel, persons who presented a risk of 
introducing a contagious disease into the United States.  Likewise, exercising the 
authority to detain noncitizens for examination “[f]or the purpose of determining 
whether [noncitizens] arriving at ports of the United States” are inadmissible “by 
reason of being afflicted with [certain] diseases,” 8 U.S.C. § 1222(a), would not 
address the same harms as Section 265, as CDC has repeatedly explained that 
holding noncitizens in congregate settings increases the risk of COVID-19 
transmission.  86 Fed. Reg. 42,828, 42,830 (Aug. 5, 2021).   
Plaintiffs also note that the government can arrest and imprison or fine 
noncitizens who cross the border.  Br. 20-22 (citing 42 U.S.C. § 271(a)).  But 
Congress’s provision of these penalties in Section 271 in no way limits CDC’s 
authority under Section 265 to use expulsion to implement the basic authority to 
prevent introduction of individuals and disease among the population.  Although 
those punishments might deter some unlawful border crossings in the first instance, 
they do not further Section 265’s purpose of averting the spread of disease caused 
by the continued presence of those who were not sufficiently deterred.  Indeed, 
imprisonment in congregate settings risks exacerbating the risk of transmission that 
the CDC Order seeks to avoid and would be contrary to the statutory purpose of 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 13 of 35

9 
 
keeping contagious persons out of the country.  It is hard to imagine that Congress 
enacted Section 265 with the expectation that individuals with a deadly and highly 
contagious disease (like COVID-19 or, for example, Ebola) would have to be 
permitted to remain in the United States—thus ensuring the “introduction” of the 
disease at issue.  Under plaintiffs’ view, the United States would be powerless to 
prevent the introduction of a novel disease, no matter how detrimental.  In light of 
the purpose of Section 265, the plaintiffs’ interpretation is implausible in context. 
Plaintiffs further suggest that Section 265 does not authorize the government 
to stop noncitizens from crossing the border.  Br. 22-23.  Notably, the district court 
did not endorse this extreme view.  1 JA 110.  Nor do plaintiffs provide any 
support for this interpretation, which would render Section 265 a virtual nullity.  
Indeed, plaintiffs’ view would render even their own interpretation of the statute 
essentially meaningless, as it would presumably preclude the government from 
stopping transportation providers from crossing the border.  If all Section 265 
permitted were after-the-fact punishment of noncitizens who unlawfully cross the 
border, it would do nothing more than the existing criminal penalty for illegal 
entry.  See 18 U.S.C. § 1325(a). 
Amicus The Cato Institute argues (at 12) that Section 265 is an 
impermissible delegation that “would give the CDC virtually unlimited authority to 
bar the entry of migrants and visitors from abroad.”  But Section 265 only applies 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 14 of 35

10 
 
where CDC determines that the “introduction of persons or property” presents a 
“serious danger of the introduction of [] disease into the United States” and the 
prohibition “is required in the interest of the public health.”  42 U.S.C. § 265.  That 
standard is at least as intelligible as others upheld by the Supreme Court.  See 
Gundy v. United States, 139 S. Ct. 2116 (2019) (plurality op.) (explaining that the 
Court has “upheld even very broad delegations,” including delegations to regulate 
in the “public interest”; to set “‘fair and equitable’ prices and ‘just and reasonable’ 
rates” ; and to issue air quality standards as “‘requisite to protect the public 
health’”). 
The Cato Institute also relies on Alabama Association of Realtors v. HHS, 
141 S. Ct. 2485 (2021), but the Court did not address the nondelegation doctrine 
there.  Moreover, in Alabama Association of Realtors, the scope of CDC’s 
authority under Section 264(a) to “prevent the introduction” of communicable 
disease was informed by the expressly enumerated powers listed in the very next 
sentence of the same subsection.  Id. at 2488.  Here, in contrast, the enumerated 
mitigation measures relied upon by the district court and plaintiffs (quarantine, 
apprehension, detention, and penalties) appear in different statutory provisions, not 
Section 265 itself.  Congress made clear that Section 265 was intended to expand 
CDC’s authority beyond the express measure of quarantine listed elsewhere in the 
Public Health Service Act.  Nor, finally, do Section 265 or the CDC Order 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 15 of 35

11 
 
“exercise powers of vast economic and political significance” or “intrude[] into an 
area that is the particular domain of state law.”  Id. at 2489.  Section 265 and the 
CDC Order do not regulate economic activity; do not directly regulate any 
domestic persons or entities; and operate in an area of uniquely federal concern.   
At a minimum, Section 265 is ambiguous, and CDC’s reasonable 
interpretation is entitled to Chevron deference.  Gov’t Br. 34-37.  Plaintiffs do not 
dispute that CDC administers Section 265 and that the challenged Order carries the 
force of law and was issued under the authority of a final rule promulgated in 
accordance with the Administrative Procedure Act.  That is sufficient to warrant 
Chevron deference.  Encino Motorcars, LLC v. Navarro, 136 S. Ct. 2117, 2125 
(2016).  Plaintiffs argue that CDC is entitled to no deference because its 
interpretation of Section 265 would override another statute it does not administer.  
Br. 40.  But that argument is plainly incorrect with respect to the primary issue 
presented: whether Section 265 by its own terms permits expulsion to avoid the 
spread of disease.  Moreover, contrary to plaintiffs’ assertion, Br. 42, CDC’s 
interpretation is rooted in its expert public-health determination that “those who 
have physically crossed a border of the United States and are in the process of 
moving into the interior * * * present a risk of transmission of a communicable 
disease” into the United States.  85 Fed. Reg. 16,559, 16,563, 16,567 (Mar. 24, 
2020).

12 
 
B. 
Plaintiffs’ Alternative Arguments Are Meritless 
Plaintiffs also raise alternative merits arguments—not reached or ruled on by 
the district court—in support of their assertion that they are likely to prevail on the 
merits.  Br. 25-40.  Putting aside the anomaly of asserting that the district court did 
not abuse its discretion based on issues it never reached, see 1 JA 112 n.6, 
plaintiffs’ arguments are meritless. 
1. 
Section 265 is Not Limited to Regulating 
Transportation Providers. 
Contrary to plaintiffs’ argument, Br. 25-31, Section 265 is not limited to 
regulating transportation providers.  Unlike neighboring provisions explicitly 
regulating “vessels” or “aircraft,” 42 U.S.C. §§ 267(b), 269, 270, 271(b), Section 
265 refers to “the power to prohibit * * * the introduction of persons” without any 
reference to their means of transportation.  “Congress generally acts intentionally 
when it uses particular language in one section of a statute but omits it in another.”  
DHS v. MacLean, 574 U.S. 383, 391 (2015). 
Plaintiffs argue that Congress used the “general term ‘introduction of 
persons and property’” to “encompass the various means of transporting 
passengers and cargo.”  Br. 28.  But elsewhere in the same statute, Congress 
expressly referred to “any merchant ship or other vessel,” as well as “its cargo, 
passenger, and crew,” 27 Stat. 449, 449-50 (1893), and its use of different words in 
Section 265 must be taken to have meaning.  Congress could also have used a 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 17 of 35

13 
 
phrase such as “steamship or transportation company or owners of vessels * * * or 
* * * [its] agents” as it had done two years earlier, 26 Stat. at 1084, or “common 
carrier,” which (despite plaintiffs’ claim, Br. 28) encompasses “transport[ing] 
freight or passengers,” Carrier, Black’s Law Dictionary, Westlaw (11th ed. 2019) 
(emphasis added).  Congress could even have used the phrase “third-party 
transportation” or “transportation providers,” as plaintiffs suggest was its intent.  
But Congress did none of that.  As one Senator emphasized in discussing what 
became Section 265, it regulated people, not their method of transportation.  See 24 
Cong. Rec. 393 (“[W]e are now legislating in regard to persons; we are now 
legislating in regard to immigration.  To say that an empty vessel may come in 
with nobody upon it is, I submit, simply begging the whole question.”). 
Indeed, when considering Section 265’s predecessor, the Senate rejected an 
amendment to bar “passenger travel” or “all passenger travel,” 24 Cong. Rec. 470.  
As Senator Palmer explained, “something more would be necessary in order to 
protect the public interest than the mere restriction upon passenger travel,” for 
example “some stronger word, such [as a] term to prohibit intercourse,” id., and 
after the “passenger travel” amendment was rejected, Senator Palmer proposed 
instead the language authorizing the “power to prohibit * * * the introduction of 
persons,” id. at 471, which the Senate adopted, id. at 471-72.  Plaintiffs 
implausibly contend that the Senate meant to “equate[]” that language with the 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 18 of 35

14 
 
rejected “passenger travel” proposal, Br. 30; in fact, the Senate did the opposite, 
adopting the language in the statute because it was not limited to passenger travel.1 
Plaintiffs suggest that the “something more” the Senate thought necessary 
when it rejected the “passenger travel” proposal was the authority to prohibit the 
introduction of property.  Br. 29.  But as Senator Chandler explained, “[i]t is not 
what the passenger brings with him * * * that is itself important to us, but it is 
important that the people who come here shall be cleanly,” 24 Cong. Rec. 366, and 
in any event he suggested that the President already possessed the power “to keep 
out infectious property; but there is no harm in adopting the amendment in this 
form,” id. at 471.  Nor did the Senate reject the “passenger travel” proposal “for 
[the] entirely different reason” that the statute lacked flexibility to apply “in whole 
or in part.”  Br. 29-30.  The Senate rejected the “passenger travel” proposal 
entirely, instead adding the flexibility conferred by “in whole or in part” to 
                                              
1 Plaintiffs (Br. 28-29) and Historians (at 10-11 & n.4) place weight on the 
fact that the rejected amendment would have prohibited “all passenger travel, but 
not immigration alone.”  24 Cong. Rec. 470 (emphasis added).  Under either 
wording, the proposal would have covered all types of passenger travel, but the 
Senate rejected that proposed amendment and instead adopted different and 
broader language prohibiting “the introduction of persons,” which contained no 
textual limitation to means of travel.

different statutory language, namely, the “power to prohibit, in whole or in part, 
the introduction of persons and property.”2  
Contrary to plaintiffs’ claim, Br. 26-31, Congress was not exclusively 
focused on passenger ships, and its Members were well aware that communicable 
diseases could be spread by persons arriving over land borders.  24 Cong. Rec. 370 
(noting the “terrible ravages [that] cholera was going to bring to this country” 
could “come from Mexico”); id. at 359 (noting immigration “coming through 
Alaska and Mexico”); id. at 364 (noting possibility of “cholera-breeding 
immigration which will come into this country by land” though Canada); id. at 
371.  Plaintiffs accuse the government of “selectively quot[ing]” Senator Chandler, 
Br. 30, claiming that he was “not afraid” of cholera coming “by land,” Br. 31.  In 
fact, Senator Chandler stated he was “not afraid, if the bill passes for the 
suspension of immigration for one year [discussed supra p. 7-8], that * * * cholera-
breeding immigration [would] come into this country by land,” 24 Cong. Rec. 365 
                                              
2 Amicus Historians (at 11) attribute the rejection of the “passenger travel” 
proposal to a debate between Senators Vilas and Gray over the degree to which the 
bill should “discriminate” among different persons.  But aside from the fact that 
these Senators were addressing different issues (Senator Vilas addressed whether 
immigrants should be treated the same as temporary visitors, while Senator Gray 
addressed the distinction between citizens and non-citizens, see 24 Cong. Rec. 
470), the Senate resolved the problem by adding the authority to prohibit “in whole 
or in part”—but to the prohibition on “the introduction of persons” rather than the 
rejected amendment prohibiting “passenger travel.” 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 20 of 35

16 
 
(emphasis added).  And as noted above, supra p. 8, rather than pursuing his bill for 
a one-year suspension of immigration, Senator Chandler voted for the competing 
bill that became Section 265, which granted the power to prohibit the introduction 
of persons, without any limitation on whether they come by land or by overseas 
vessel.3 
Plaintiffs contend (Br. 27-28) that the only time Section 265 was invoked 
prior to 2020 to prohibit the introduction of persons was by regulating 
transportation providers.  But the relevant executive order in fact addressed how 
persons “may be introduced directly or indirectly by transshipment or otherwise 
into the United States.”  2 JA 203 (emphasis added).  Regardless, it is not 
surprising that an executive order applying only to persons coming overseas from 
China or the Philippine Islands would focus on transportation vessels, which would 
have been the only practical means of coming to the United States from those 
locations in 1929.  This example says nothing about the authority under Section 
265 to address the threat of contagious disease from noncitizens arriving at 
Canadian and Mexican land borders, where the introduction of a person does not 
require a transportation provider. 
                                              
3 Plaintiffs also object that other Senators criticized Section 265 for failing to 
address persons arriving by land, Br. 31, but those statements were made before 
the bill was amended to authorize the “power to prohibit * * * the introduction of 
persons.”   
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 21 of 35

17 
 
In the end, plaintiffs do not dispute that their interpretation would lead to the 
illogical conclusion that passengers could simply disembark offshore, or just 
before the border, and then enter the country without violating the statute; they 
merely question whether that scenario is likely.  See Br. 31.  But one Senator noted 
this exact problem, observing that “it is an open and notorious fact that for want of 
patrol people were escaping from the ships and getting to shore more or less during 
that whole quarantine” the previous year.  24 Cong. Rec. 373.  Plaintiffs also 
question why a commercial entity would risk penalties by engaging in that 
behavior.  But the relevant question for interpreting the statute is why Congress 
would have left such an obvious and gaping loophole in Section 265, not why the 
supposed subject of regulation would risk violating the statute.   
2. 
Section 265 Does Not Irreconcilably Conflict with 
Immigration Provisions, but in Any Event, Section 
265 Would Control. 
Plaintiffs argue that CDC’s interpretation of Section 265 unlawfully 
conflicts with provisions of the immigration laws providing humanitarian 
protections without the requisite clear congressional intent to do so.  Br. 34-40.  
But as we have explained, Gov’t Br. 40-41, the statutes are readily harmonized:  
the immigration provisions that plaintiffs invoke apply in normally prevailing 
conditions in the absence of a rare public-health emergency, whereas Section 265 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 22 of 35

18 
 
is an emergency public-health provision that applies only in specific, limited 
circumstances. 
Nor do plaintiffs seriously contest the drafting history of Section 265, which 
demonstrates that Congress amended the statute to change the authority for a 
“suspension” of “immigration” to an authority for a “suspension of the right to 
introduce * * * persons,” making clear that Section 265 authorized both the 
prohibition on immigration and the prohibition on tourists and other temporary 
visitors.  Gov’t Br. 41-43.  And contrary to plaintiffs’ claim, Br. 38, “a very strong 
argument” put forward in floor debate in favor of Section 265 was that it made 
“quite clear that * * * the purpose of the law” includes “the power to suspend 
immigration altogether,” 24 Cong. Rec. 393, and that it grants “very extraordinary 
powers” including “a total embargo upon immigration,” id. at 470.  Plaintiffs then 
argue, implausibly, that Section 265’s authorization for the suspension of 
immigration does not include the suspension of immigration “laws.”  Br. 37. 
Plaintiffs also object that under the government’s construction of Section 
265, “there is no bar to indefinitely overriding the asylum statutes.”  Br. 36.  By its 
plain terms, however, Section 265 applies only where CDC determines that the 
“introduction of persons or property from such country” presents a “serious danger 
of the introduction of such disease into the United States,” and the prohibition “is 
required in the interest of the public health.”  42 U.S.C. § 265.  Section 265 is thus 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 23 of 35

19 
 
a limited exception that is applicable only under emergency conditions—and 
which has only rarely been invoked.  See 85 Fed. Reg. 56,424, 56,426 (Sept. 11, 
2020) (“This authority is available only in rare circumstances when ‘required in the 
interest of the public health.’” (quoting 42 U.S.C. § 265)).  Moreover, the CDC 
Order is subject to recurring 60-day reviews.  1 JA 131.  Nor should the Court give 
any weight to plaintiffs’ unsupported suggestion that the government will abuse its 
authority under Section 265 to “eliminate humanitarian protections whenever it 
deems it expedient.”  Br. 36; cf. Latif v. Obama, 677 F.3d 1175, 1178 (D.C. Cir. 
2011) (“The presumption of regularity supports the official acts of public officers 
and, in the absence of clear evidence to the contrary, courts presume that they have 
properly discharged their official duties.” (quotation marks and citation omitted)).  
Further, plaintiffs do not dispute that the government’s implementation of the CDC 
Order provides a process for determining a covered noncitizen’s claim for 
protection under the Convention Against Torture (CAT).  See Dkt. 76, at 29 n.15 
(explaining that the Department of Homeland Security (DHS) will refer a 
noncitizen to U.S. Citizenship and Immigration Services for a CAT screening if the 
noncitizen claims a fear of torture); Br. 35 n.6.  Thus, noncitizens would not be 
expelled without some opportunity to seek humanitarian relief. 
Plaintiffs acknowledge that Section 265 provides for a “suspension of the 
right to introduce such persons” (emphasis added), but they argue that this 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 24 of 35

20 
 
language cannot provide for the temporary suspension of immigration laws 
because it is found in a “dependent clause.”  Br. 37.  Section 265’s grammatical 
structure, however, does not undermine Congress’s clear intent that it permits the 
temporary displacement or suspension of immigration laws that otherwise provide 
certain rights to noncitizens.  Indeed, if plaintiffs were correct that a “dependent 
clause” cannot authorize the suspension of other laws, it would undermine their 
own theory that Congress authorized the suspension of transportation provider 
licenses, see Br. 38 n.8. 
3. 
The Constitutional Avoidance Doctrine is 
Inapplicable.  
Plaintiffs argue that Section 265 cannot include the power to expel because 
that authority would raise grave constitutional questions if applied to U.S. citizens.  
Br. 36-37.  But plaintiffs do not dispute that neither the final rule nor the CDC 
Order applies to U.S. citizens.  42 C.F.R. § 71.40(f); 1 JA 148.  Nor do plaintiffs 
dispute that interpreting Section 265 to permit CDC to stop persons (including U.S. 
citizens) from crossing the border would raise the same constitutional concerns.  
See Gov’t Br. 44.  Plaintiffs’ only answer is to question whether Section 265 
authorizes even that limited step as a statutory matter, Br. 24 n.3, which avoids the 
constitutional issue by construing the statute to be a virtual nullity, see supra p. 10. 
If CDC were ever to invoke Section 265 to expel U.S. citizens (or 
indefinitely bar their re-entry), a court could at that point address whether such an 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 25 of 35

21 
 
order would be unconstitutional as applied to U.S. citizens, cf. Reno v. Flores, 507 
U.S. 292, 305-06 (1993), or whether constitutional concerns call for an implicit 
exception for U.S. citizens, cf. Our Lady of Guadalupe Sch. v. Morrissey-Berru, 
140 S. Ct. 2049, 2060 (2020).  This Court should not preemptively adopt a 
narrowing construction of the statute that does not eliminate the very constitutional 
concerns that are the purported basis for that construction. 
II. 
The Remaining Preliminary Injunction Factors Do Not Support 
An Injunction 
The district court also erred in concluding that the remaining preliminary 
injunction factors weigh in favor of plaintiffs.  The preliminary injunction 
threatens irreparable harm to the government and the public at large. 
There can be little doubt that the district court’s preliminary injunction 
would increase the risk of the transmission of COVID-19 among noncitizens, U.S. 
Customs and Border Protection (CBP) personnel, and the public at large.  The 
injunction would require the government to hold covered family units in 
congregate settings for hours or days while they undergo immigration processing, 
in facilities that are not equipped for physical distancing, quarantine, or isolation at 
the best of times, and that are now substantially over their COVID-restricted 
capacity.  1 JA 176 ¶ 21.  CDC’s discretion to respond to the public-health 
emergency—including both its decision about whether to prohibit the introduction 
of persons from particular countries and in what circumstances, and its authority to 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 26 of 35

22 
 
except certain classes of people from its Order—is critical to avoiding irreparable 
harm to the public.  CDC is scheduled to complete its next periodic review on 
November 30, 2021.  See Gov’t Br. at 14 (discussing CDC’s recurring 60-day 
reviews).   
Plaintiffs argue that noncitizen family units are not a “meaningful source of 
COVID-19.”  Br. 46-49.  In support of this argument, plaintiffs rely on high 
positivity rates within the United States and border states.  Br. 47-48.  Plaintiffs’ 
argument only underscores CDC’s conclusion that temporarily suspending the 
introduction of certain noncitizens traveling from Canada and Mexico, including 
members of family units and single adults, “remains necessary in light of the 
current circumstances” and rising positivity rates.  1 JA 132, 133, 135.  Rising 
positivity rates exacerbate the exact strain on the healthcare system that the CDC 
Order is meant to avoid, and CDC’s expert public-health judgment is entitled to 
deference.  Moreover, plaintiffs’ observation that noncitizen members of family 
units are a “tiny fraction” of “cross-border traffic,” Br. 48, is a meaningless 
comparison.  The vast majority of those travelers do not require extended Title 8 
processing in congregate settings—the source of the risk that CDC seeks to 
address—and the ones that do (e.g., single adults lacking valid travel documents) 
are also subject to the Order.  Moreover, even small numbers of contagious 
individuals can lead to substantial spread in crowded CBP facilities.  The 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 27 of 35

23 
 
injunction inhibits CDC’s authority to respond effectively to changes in the public-
health environment and the status of the pandemic.  
Plaintiffs also fault the government for not expanding testing, vaccines, and 
other mitigation protocols.  Br. 49-54.  But plaintiffs’ unfounded assertion that 
“DHS has simply failed to act” is undermined by the record in this case.  Br. 50.  
DHS is moving expeditiously to implement and expand the use of robust COVID-
19 mitigation measures and has been working since January 2021 to build greater 
capacity.  See, e.g., 1 JA 170 ¶ 4 (government declarant explaining that “DHS has 
worked tirelessly to build capacity and to create innovative new approaches to 
allow asylum seekers and other noncitizens to be processed in a manner that 
ensures * * * health and safety”); 1 JA 171-173 ¶¶ 7-12.  Despite these efforts, 
DHS still “lacks sufficient capacity” to process all individuals seeking to enter the 
United States, and the problem is “particularly acute with respect to families.”  
1 JA 170 ¶ 5.  CDC has concluded in its expert public-health judgment that the 
“extreme population density and the resulting increased time spent in custody by 
noncitizens” in CBP facilities currently pose significant risk.  1 JA 141.  In 
addition, risk-mitigation efforts are constrained by requirements to hold various 
population cohorts separately, as well as resource and physical constraints that 
make isolation and separation of those who test positive for COVID-19 infeasible.  
1 JA 141-42.  The fact that certain local organizations might have available 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 28 of 35

24 
 
capacity to receive and transport families after they have been processed by CBP, 
Br. 51, does not address the risk that the Order is meant to address, i.e., the risk of 
spread of COVID-19 if CBP must hold family units in overcrowded CBP facilities 
pending immigration processing.   
Plaintiffs argue that “CDC’s exemption of unaccompanied children 
demonstrates that COVID-19 risk can be safety mitigated” for family units.  
Br. 50.  But CDC explained that unaccompanied children “are differently situated” 
than single adults and individuals in family units for several reasons, including that 
“[t]he number of [unaccompanied children] entering the United States is smaller 
than both the number of [single adults] and of [members of family units].”  1 JA 
145; see also Gov’t Br. 52-53.  As the government has explained, the United States 
“is currently encountering record numbers of noncitizens, including families, at the 
border,” 1 JA 169 ¶ 3, and an even greater increase could be expected if the 
injunction were to be affirmed and take effect, 1 JA 156 ¶ 7; 1 JA 161 ¶ 14; 1 JA 
177 ¶ 2; Gov’t Br. 48.  There is “an historic surge in southwest border encounters 
in recent months” and the “capacity challenges are particularly acute with respect 
to families.”  1 JA 170 ¶ 5; 1 JA 174 ¶ 17; Gov’t Br. 47. 
Plaintiffs also contend that the vaccine mandate for federal workers and the 
availability of vaccines for children starting at the age of five can help mitigate the 
COVID-19 risks associated with processing additional family units.  Br. 52.  But 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 29 of 35

25 
 
many people covered by the CDC Order originate from countries with “markedly 
lower vaccination rates.”  1 JA 138; see also 1 JA 170 ¶ 3 (DHS “is also 
experiencing significantly increased rates of noncitizens testing positive for 
COVID-19”).  And even if the government could vaccinate all willing and eligible 
members of family units encountered, that would not eliminate the potential harm 
given the period of time before vaccination would be effective.  Nor do plaintiffs 
dispute that the Delta variant also increases the risk of breakthrough infections 
even among the vaccinated.  1 JA 135, 138. 
Plaintiffs note that DHS is permitting vaccinated foreign travelers to enter 
the United States.  Br. 53.  But those travelers will not spend hours or days in 
congregate settings while undergoing immigration processing, unlike the 
noncitizens covered by the CDC Order.  See 1 JA 143 (explaining that individuals 
in family units who are not expelled under the CDC Order, but who would be 
processed under Title 8 because of the district court injunction, would spend an 
average of 62 hours in custody at CBP facilities, and that “[i]f the CDC Order were 
not in place * * * time in custody would likely increase significantly”). 
Plaintiffs assert that, because in June 2021 the government was unable to 
apply the CDC Order to approximately 86% of individuals in family units, 
primarily as a result of foreign government restrictions, 1 JA 143 & n.80, enjoining 
application of the CDC Order to the remaining family units would not “impose a 
USCA Case #21-5200      Document #1924454            Filed: 11/29/2021      Page 30 of 35

26 
 
substantial burden on DHS.”  Br. 54-58.  But under the Order, the government 
expelled more than 8,000 individuals in family units per month in May and June 
2021, and over 10,000 and 16,000 in July and August 2021, respectively.  1 JA 
174-75 ¶¶ 17-18; CBP, Southwest Land Border Encounters, 
https://go.usa.gov/xeQ8Y (last modified Nov. 15, 2021) (interactive dashboard). 
The number of individuals in family units encountered monthly has nearly doubled 
from May to August 2021 (from 44,000 to 86,000), id., and is expected to escalate 
sharply if the preliminary injunction were to take effect, as the application of the 
CDC Order has been a significant deterrent to the entry of family units who qualify 
for processing under the CDC Order, 1 JA 177 ¶ 23; 1 JA 156, 161.4  Furthermore, 
two Border Patrol sectors on the Southwest Border have seen a disproportionate 
share of the encounters, resulting in “extremely worrisome” statistics, with one 
section at 783% over COVID-adjusted capacity as of August 2021.  1 JA 175-76.5   
Plaintiffs also assert that the balancing of harms weighs in favor of a 
preliminary injunction because noncitizens who hope to come to the United States 
                                              
4 Despite plaintiffs’ claim of inflated statistics due to repeat crossings, 
Br. 54-55, their own statistics show only a 16.8% recidivism rate for family units 
in the first nine months of fiscal year 2021, 2 JA 462, which is dwarfed by the 
surge in the number of family unit encounters, 1 JA 175-76. 
5 Overcapacity or other factors might necessitate the transfer of noncitizens 
to other regions for processing under the CDC Order, Br. 53, but those risks from 
overcapacity and transfer would be substantially exacerbated if the government 
were required to process all noncitizen members of family units under Title 8.

but are barred from doing so, or who have been encountered in the United States 
and expelled under the CDC Order, have been victimized by criminal gangs in 
those foreign countries.  Br. 42-45.  This is a deplorable situation, and the U.S. 
government has been taking action to provide additional protections for vulnerable 
individuals subject to the CDC Order.  Of note, the United States has excepted 
from the Order particularly vulnerable families, in partnership with 
nongovernmental organizations—an effort that has resulted in the exception of 
over 16,000 individuals from the CDC Order.  1 JA 172 ¶ 11.  As noted by 
plaintiffs and certain amici, participating nongovernmental organizations have 
recently decided to cease assisting the U.S. government in implementing this 
process, which has hampered such efforts.  But the government nonetheless 
continues to grant case-by-case exceptions based on the totality of the 
circumstances, including humanitarian considerations, and will continue to do so.   
The issue before the court is whether the federal government is disabled 
from taking quick action, based on the reasoned decision of the nation’s public-
health authorities, to protect the public health in circumstances that pose a risk of 
spread of COVID-19 not just for covered noncitizens but for CBP personnel and 
the U.S. public.  With all respect, the government submits that it is not.
