21 States File Lawsuit Against CDC Mask Mandate For Public Transportation
The lawsuit raises some of the same issues as earlier successful challenges against the CDC's eviction moratorium. But, in this case, the federal government has a stronger legal rationale for its policies.

Yesterday, twenty-one mostly "red" states led by the state of Florida filed a lawsuit challenging the Centers for Disease Control (CDC) mandate requiring mask-wearing on public transportation and at transportation hubs, such as airports. The CDC claims that the mask mandate policy is authorized by 42 USC Section 264(a), the very same law that agency used to try to justify its nationwide eviction moratorium, which was invalidated by the Supreme Court in August, after a prolonged legal battle in the lower courts. The Court concluded (correctly, in my view) that the eviction moratorium lacked proper congressional authorization. The plaintiff states clearly hope to get a similar outcome with the mask mandate.
While the two cases raise related issues, I think the mask mandate is on much firmer legal footing than the eviction moratorium was. Courts may well uphold it.
I am far from happy about that prospect. I am deeply opposed to mask mandates, with the possible exception of a few highly specialized settings. In my view, their very modest public health benefits are greatly outweighed by the severity of this restriction on liberty, the pain and discomfort caused by mandatory mask-wearing, and the undermining of normal human interaction (which often depends on seeing people's facial expressions). Mask mandates are especially reprehensible at a time when vaccination is available to virtually all Americans over the age of 5 (and those under 5 face very low risks even without vaccination), for the vast majority of vaccinated people the risks of Covid are comparable to or less than those of the flu, and highly risk-averse individuals can still protect themselves with one-way masking. Further, as Reason's Jacob Sullum explains, the CDC's perpetuation of the transportation mask mandate makes no sense at a time when the agency is recommending against mask mandates in almost every other setting, including many where the risk of infection is substantially greater.
But this is one of those cases where law and justice may be at odds with each other. The legal problems that doomed the eviction moratorium are much less evident in this case.
Section 264(a) gives the CDC the following powers:
The Surgeon General, with the approval of the [Secretary of Health and Human Services], is authorized to make and enforce such regulations as in his judgment are necessary to prevent the introduction, transmission, or spread of communicable diseases from foreign countries into the States or possessions, or from one State or possession into any other State or possession. For purposes of carrying out and enforcing such regulations, the Surgeon General may provide for such inspection, fumigation, disinfection, sanitation, pest extermination, destruction of animals or articles found to be so infected or contaminated as to be sources of dangerous infection to human beings, and other measures, as in his judgment may be necessary. [a later statute gives this authority to the CDC rather than the Surgeon General]
The Trump and Biden administrations claimed the agency could enact a nationwide eviction moratorium under the catch-all provision authorizing "other measures" that the CDC considers "necessary" to stop the spread of disease.
The Supreme Court rejected that position because, if applied consistently, it would give the agency the power to suppress almost any activity that involves movement or interactions between people. Such sweeping authority is at odds with the more limited nature of the other authorities listed in the statute, and "other measures" should - the Court concluded - be interpreted as allowing only measures similar to the others listed in Section 264. In addition, the Court emphasized that interpreting Section 264 to grant the CDC the vast power it claimed is at odds with the "major question" doctrine, which requires Congress to "speak clearly when authorizing an agency to exercise powers of "vast 'economic and political significance.'"
Several lower court decisions on the eviction moratorium also concluded that it violated constitutional limits on the delegation of legislative power to executive agencies. The government's ultra-broad interpretation of Section 264 would give the CDC enormous power to ban virtually any human activity. If that isn't a nondelegation problem, it's hard to see what would be. I discussed the nondelegation and major question issues in the eviction moratorium case in greater detail in this article.
The CDC transportation mask mandate differs from the eviction order in a number of crucial ways. I summarized them in this March 2021 post:
Law Professor Lindsey Wiley, a leading academic expert on public health law worries that the reasoning adopted in Skyworks and Tiger Lily [two lower court rulings against the eviction moratorium] could potentially lead courts to invalidate the Biden administration's order requiring the wearing of masks on various types of interstate transportation, which also relies on Section 264(a) for authorization.
I think this is unlikely because the focus on transportation is much more closely related to the purpose of preventing the "spread of communicable diseases from… from one State or possession into any other State or possession." In addition, limiting it to transportation may fall into the category of promoting the "sanitation" of "articles" that facilitate the spread of disease across state lines. In this case, the relevant "articles" would be seats and air spaces on buses, airplanes, and other modes of transportation covered by the mask order. These distinctions may be the reason why Biden's advisers concluded (correctly, in my view) that he did not have the power to order a general nationwide mask order, but could impose a much narrower one focused on transportation.
Unlike the eviction moratorium, the mask order need not rely on an ultra-broad interpretation of the vaguely worded "other measures" provision. It could instead potentially be based on the more specific provisions authorizing regulations promoting "sanitation." For this reason, it is less likely to raise major question and nondelegation problems. Stretching the term "sanitation" to cover mask mandates wouldn't give the CDC the power to suppress virtually any human activity, though it might allow it to mandate other intrusive restrictions on public transportation, such as wearing even more restrictive protective gear (gloves, hazmat suits, and so on).
I readily admit it may be possible to come up with plausible narrower interpretations of "sanitation" that would exclude mask mandates. The issue isn't completely one-sided. But the government's position here is a lot stronger than it was in the eviction moratorium litigation.
In addition to relying on the eviction moratorium precedent on the "major question" issue, the plaintiffs in the mask case also argue that the CDC order violates constitutional constraints on federal commandeering of state governments, by requiring the latter to enforce the mandate in state-owned transportation facilities. This argument is similar to that successfully made in other contexts where the federal government tries to compel states and localities to help enforce federal laws and regulations, including gun regulations, and the sanctuary cities cases.
I think the anti-commandeering argument has merit, though the federal government might be able to overcome it by claiming that the states are merely being regulated in the same way as owners of private transportation facilities. But even if the states prevail on that point, it wouldn't lead to the end of the mask mandate; it wold only end the requirement that states help enforce it. In many contexts (such as with the War on Drugs), the federal government must rely on state cooperation to enforce federal law, because there are many more state law-enforcement agents out there than federal ones. Airports, however, are among the few places where there are often large numbers of federal law-enforcement personnel present on a regular basis, such as TSA employees. Thus, the feds can more easily "go it alone" here than in many other situations.
The Florida-led lawsuit isn't the first legal challenge filed against the transportation mask mandate. The state of Texas (joined by Rep. Beth Van Duyne) filed an earlier suit last month. But the multi-state lawsuit is by far the most high-powered and high-profile case of this type.
In addition to the substantive issues these cases raise, there are some procedural questions involved. For example, the federal government might try to get the state plaintiffs dismissed on procedural grounds, such as by claiming they don't have standing. Over the last couple years, the Supreme Court has tightened the procedural screws on state lawsuits against the federal government, most recently in the Obamacare severability case.
I won't go into detail on these procedural issues here. But I tentatively predict that courts will not dismiss these cases based on standing or other procedural grounds, and will have to reach the merits. Among other things, the fact that the mandate applies on state-owned property and requires states to help enforce it gives them a strong argument that the states suffer tangible harm from the policy.
Finally, it's possible this litigation will be mooted out if the transportation mask mandate expires on April 18, as currently scheduled. But the mandate has been extended several times before, and it is far from clear whether the Biden administration will do so again.

They sued in the U. S. District Court for the Middle District of Florida.
Under any theory of Constitutional interpretation, is there anything to justify states filing in any federal court besides the U. S. Supreme Court?
The supreme court doesn't much like to exercise original jurisdiction, so it's probably not a good idea to start out on a bad foot.
I assume you're referring to the portion of Article III stating that, "[i]n all Cases . . . which a State shall be Party, the supreme Court shall have original Jurisdiction." For better or worse, the Court has interpreted this language as discretionary, e.g., United States v. Nevada & California, 412 U.S. 534, 538 (1973), with the result that it doesn't entertain most original-jurisdiction filings. That in turn leaves the states to file in district court instead.
The sooner they get rid of all covid restrictions the better.
I had to take two hours out of my day today to get a covid test so I can fly back into the US tomorrow.
I've had to take 2 hours of UNPAID time out of my day every Thursday for last 12 weeks and continuing on indefinitely into forever so I can go to work- where I work by myself but for 5 minutes turnover at the beginning and end of each shift.
Exhibit 1
https://91-divoc.com/pages/covid-visualization/
covid is a respiratory virus
covid basically ignored all the mitigation protocols
Covid basically ignored all the vaccines
"covid basically ignored all the mitigation protocols"
that statement is at best a gross exaggeration and at worst an outright lie.
Nico
It is a gross exaggeration to claim the mitigation protocols had any substative impact on reducing the effect of covid or transmission of covid. Absent hard lockdowns, the results were about the same. In cumulative death rate by age was remarkably similar accross every state in the US, with the exception of me, vt, nh, ha, wa which were much lower.
Don - run the numbers of cumulative covid deaths by age group across any region state or county. You will find remarkable consistency in hte cumulative rates by age group irrespective of Blue state red state and level of mitigation protocols.
Joe,
The science of spread of aerosols in confined spaces is pretty clear. The susceptibility of the immuno-compromised is also clear. Statewide data you refer to is irrelevant to a mask mandates in public transportation, especially on planes when the space is highly restricted and exposure is multiple hours long.
So, you support eliminating food and drink services in those confined spaces? Because unless you do everyone is still subject to exposure. And you support masking forever because the virus is never going away and there are always going to be immuno-compromised people? Not to mention all the other viruses that have been with us forever.
Keith,
Do not put your words in my mouth. BUT incidentally there are spaces in which NO food and NO beverages are allowed.
But I'll answer you question. If need be, masking on planes were indefinite, yes, I would support that during flu season.
I respect your consistency. I reject your position absolutely.
Sure, if you live in false choice world. The amount of virus an infected passenger expels is much less if they mask during all the hours they're not eating and drinking than if they don't mask at all.
"much less"? How much less? Or, rather, how much does this "much less" change the risk of infection for others?
For cloth masks and paper masks less than 12-layers, the answer is "indistinguishable from zero".
"Mask mandates are especially reprehensible at a time when vaccination is available to virtually all Americans over the age of 5"
Nonsense, Ilya. While the vaccines do poorly at preventing the spread of diseases as contagious as Omicron variants they do considerably reduce the risks of serious disease. Masks have many flaws but they do reduce probability of transmission in confined spaces when used properly. That consideration is critical to immuno-compromised people.
Your "especially reprehensible " is just your selfish libertarianism screaming out
Don - I am looking at the hard empirical data , not the theorical data.
Absent hard lockdowns, the mitigation protocols did little or nothing to slow the spread.
Joe,
State average data are irrelevant to utility of lower risk of contagion in confined spaces especially with respect to immuno-compromised individuals
My biggest problem with mask mandates is they were not authorized by Congress. The constitution didn't establish an national health police with that power, so it needs to be done by Congress.
There's also the question of whether Congress even has the Constitutional authority to do it in the first place. I'd argue that they don't have the authority to create such a national health police.
KeithK,
The FAA does have responsibility for passenger safety on airplanes. Would that hold up in Court, I have no idea. But if your claim is that Congress has said nothing about passenger safety due to health conditions, you're not correct.
Look at the legislation for yourself. And don't ask me for a citation.
Congress has no constitutional authority to delegate its rule making to administrative agencies. Period.
"they don't have the authority to create such a national health police."
There you go again, making a strawman that no one but yourself has offered
That was me misreading the post I was replying to. Mea culpa.
Is anything more predictable than a comparison of
(1) the list of plaintiffs in this case
and
(2) the list of states ranked by educational attainment?
Roughly as predictable as the course of America's not-quite-concluded-but-settled culture war.
"If you have any poo, fling it now."
I'd be much more interested in the legal questions raised had these suits been filed last summer or in 2020. At this point they're really much more about political pressure. There was little justification for extending this rule in March but the WH did it anyway. There's even less reason to extend it again. But then the WH is filled with "Very Liberal" types who are vastly more likely to still consider the virus a grave threat (see recent polls and pretty much all available evidence) so one can imagine them wanting to continue the rules out of a foolish abundance of caution. The more the political opposition piles up against this the less likely it will be to happen. And that alone is reason to applaud the lawsuits.
I don't have a legal opinion on the validity of the airline mask mandate under federal law. (Obviously I oppose it from a policy perspective.) What I want to know is how the feds can claim any authority over intrastate public transportation systems.
They claim walking across the street is interstate commerce because the next car going by may be going out of state.
The plain text of the law says it's to prevent spread from one state (or country) to another, not to prevent spread in general. There's very little justification for a mandate that applies to even just interstate travel when it's already prevalent in every state, and no justification at all for mandates on intrastate travel. This will get struck down at least partially, and probably entirely (unless, of course, the mandate is magically lifted right before the courts can consider it.)
Well, it's not like an airplane has as good an air filtering system as an operating room or anything.
Long,
The proximity-duration product aboard aircraft in economy class is far higher than in almost any other indoor circumstance. The air filtration systems are good, but the neighboring passenger is cheek by jowl close.
" by the severity of this restriction on liberty, the pain and discomfort caused by mandatory mask-wearing, and the undermining of normal human interaction (which often depends on seeing people's facial expressions)"
Holy fucking hyperbole. Especially compared to the restrictions on liberty you're perfectly fine with.
"Pain and discomfort"? Only because of political delusion caused by too much Fox News.
If you think masks during a pandemic are a big deal, you need to do a complete top to bottom review of all the restrictions on liberty you've defended and apologize for such reprehensible hypocrisy and intellectual dishonesty.
To allow the CDC unchecked masking authority is to accede it unbridled power over the citizenry. There are always diseases spreading about, and the CDC can always claim a national interest for their pronouncements. The judicial branch, at its core, is supposed to exercise a "common sense" check on all government functioning.
In early March of 2020 there was far less Covid virus in the U.S. than there is today. One million people were about to be killed in consequence.
On the other side of the issue, vaccination and prior infection have rendered probably somewhat more than half the population marginally safe, if not immune from infection. That leaves 100+ million still fully vulnerable. Among that 100+ million are some 10– 30-million who cannot be made safe by vaccination, because of either immune compromise or advanced old age.
The virus has shown repeatedly that it is as implacable as a mathematical equation. Supply conditions which allow it to increase, and it does. It is entirely reasonable to conclude that with a laissez faire public health policy about Covid, notably more millions could die. Except for benign happenstance, which no one can reasonably expect, only aggressive public health policy can prevent that.
Suggestions that the pandemic is over are unfounded. Assertions that no one is still vulnerable are lies. Willingness to ignore the fate of 10– to 30-million people who cannot return to normal lives except by suppression of the pandemic—and who will continue at risk of early death until that happens—is morally monstrous.
The frivolous selfishness of anti-public-health advocacy in this nation is the main explanation for why the U.S. shows proportionally more Covid deaths, and notably more economic disruption, than comparable developed nations elsewhere.
Within the U.S., county-by-county mortality data show a malign correlation with partisan politics, with red state citizens dying disproportionately. The NYT publishes daily a county-by-county map to show Covid per-capita death rates. To anyone who knows politics and can read a map, the political effect is clear-cut.
Pro-Covid advocacy, like that published by commenters to this thread—and even by Somin with his disregard for the immune compromised—ought generally to be described as ignorant, or morally degenerate, with the latter far too important in the mix.
The problem with your argument is that you are holding two contradictory beliefs at the same time. On the one hand, you say,
but then later,
Well which is it? Is the virus "implacable" or is it "suppressible"? It can't be both. The correct answer is it is implacable, and some things can be done to reduce it, but it cannot be completely suppressed.
In light of which, the first thing we are obligated to do is to not waste our efforts. I completely disagree that there is even any correlation between politics and the virus' effects, much less evidence of causation. Two years in and we're still arguing over this point? That's a true waste of everyone's efforts.
DaveM, your argument presumes that public health measures to do not reduce opportunities for Covid to increase. Perhaps that is where you want the debate to come out, but assuming it from the beginning is not only bad form, it is also mistaken.
DaveM, your disagreement on the correlation between politics and virus effects cannot survive a forthright inspection of the NYT fatality map. Want to find Biden voters on the fatality map? Look for pale islands surrounded by darker reds and oranges. Almost every such instance will turn out to be a major urban area surrounded by a Trump-voting hinterland. You are in denial about politics and Covid.
"probably somewhat more than half the population marginally safe"
You do realize that even prior to any vaccine, even without any masking or other protocols or literally anything other than ameliorative care for victims, that statement would still be true, right?
No. Acquired immunity fades and gets bypassed just like viral immunity. Relying on either alternative as the sole way to control Covid is foolish, as experience in this nation and abroad has shown.
vaccination immunity, not "viral" immunity
The U.S. and Mexico have proportionally more Covid deaths than other countries because the people are fat. Covid kills people who are old and fat.
Brophy, taking your calumny at face value, red-county voters must be notably older and fatter than blue county voters. That may be true, but I fail to understand on what principle you interpret it as moral justification for letting red-county voters die needlessly.
There are certainly some number of people who remain vulnerable. Let those individuals make risk assessments and take appropriate steps to protect themselves. It's wrong to force the rest of society to suffer under restrictions on their behalf. Particularly because those same people were vulnerable to seasonal respiratory illness prior to the current pandemic and would continue to be vulnerable if we could eliminate Covid entirely. But there is NO WAY to get rid of Covid. It's here with us forever. We have to learn to live with it. I for one reject the idea that wearing masks forever is a reasonable means of living with it.
I for one reject the idea that wearing masks forever is a reasonable means of living with it.
And to be damned certain that you don't have to wear a mask even intermittently, you advocate imposing that requirement full-strength on millions of others who are genetically less fortunate than you. You do that frivolously, without reflection about whether public health measures organized and executed when the virus was at low ebb could make infections so uncommon that everyone, including the immune compromised, could escape customary masking. Worse, the recklessness you claim as a privilege, will predictably lead to deaths among a far larger group than the immune compromised. Those include also the ignorant and doctrinaire, who, whatever their faults, do not deserve to die needlessly.
I and the people whose experience I know of have experienced zero pain from masking and only trivial discomfort (though that damned glasses fogging is aggravating).
The benefits do indeed depend critically on the grade of mask, and "modest" is a charitable word for single-layer cloth. Some numbers have been gathered:
https://www.cdc.gov/mmwr/volumes/71/wr/mm7106e1.htm
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7883189/
Technically, what I wear is not even a "mask", but a "respirator". It cleans up most of the residual risk not covered by my Moderna-trained immune system.
As infringements on liberty go, a mask mandate feels less like a seat belt law and more like a law requiring me to drive on the right hand side of the road.
BTW, my thanks to the people with informative comments about original jurisdiction. It is a treat to learn things.
There are two types of masks: one is designed to keep droplet-sized liquids and particles from escaping from your mouth and nose and infecting others -- these are the "surgical" types of masks. The other is designed to keep dust-sized particles from entering your mouth and nose from your environment. These are the "respirator" type of masks.
So, how big are these things which the masks are designed to block?
Dust particle: 100 micrometers
Water droplet: 50-100 micrometers
The covid virus, however, is airborne. It is not the size of a droplet or a particle of dust. It is not even the size of a smoke particle. If you can smell smoke through a mask, then the particles are entering your body. So, how small of a size are we talking about?
Smoke particle: 1 micrometer
Covid virus: 0.3 micrometers
It should be abundantly clear just from these simple facts alone that it is exceptionally difficult to prevent the spread of any airborne virus with a mask, even under the best of conditions. You'd have to wear an entire filtration system with multiple layers of filters and a forced-fed airflow blower on your head to really do the job.
In other words, a hazmat suit.
Incidentally, there are also two kinds of facts: DaveM 'facts' and actual established facts agreed upon by most everyone else.
Ask yourself which of the two the "masks are useless" fact likely stems from. It's the same one claiming that COVID is transmitted by pores bigger than 0.3 micrometers.
It is also not true that masks can't filter down to that size. N95 masks filter approximately 95% of particles 0.3 microns in size. It's literally in their name.
If you listen to DaveM, you're listening to an uninformed idiot.
Actually, you're both wrong on multiple counts - so you've got that in common.
N95 respirators made by different companies were found to have different filtration efficiencies for the most penetrating particle size (0.1 to 0.3 micron), but all were at least 95% efficient at that size for NaCl particles.
Upon analysis of negative-stained SARS-CoV-2 articles by electron microscopy, different researchers have had varying results, but the diameter of the virus has been found to range between 50 nm to 140 nm.
50 nm = .05 μm, 140 nm= .14 μm. So they're smaller than the vaunted mask filtration rated size.
Want to find out real world mask efficiency? Wear an N95 mask. Find someone with an oil fired boiler. Open the combustion chamber and spend 30 minutes to an hour brushing and cleaning it. Then blow your nose. And tell me how in the real world you expect the magical talisman mask to stop virus transmission dead in it's tracks. I've performed this experiment- except not as an experiment- Little hint- the skin underneath the mask will be slightly less dirty than the skin around it. The inside of your nose will be caked with soot particles far larger than 50-140 nm.
The laboratory test showing the masks 95% efficient at stopping those 3 μm particles was just that- a laboratory test under controlled conditions. My final stage water filtration is 0.5 μm string wound filter. Yet, sand particles get past it. Not many, but they do.
"The Surgeon General, with the approval of the [Secretary of Health and Human Services], is authorized to make and enforce such regulations as in his judgment are necessary to prevent the introduction, transmission, or spread of communicable diseases from foreign countries into the States or possessions"
Let's sue the Surgeon General for not doing his job. He's done nothing "to prevent the introduction, transmission, or spread of communicable diseases from foreign countries into the States or possessions". Just look at the situation on the Southern Boarder.
The Surgeon General should be requiring men who have sex with men to wear condoms. That would do a lot more for public health than face diapers.
So to be clear, Congress never ever passed any law saying that you have to wear a face diaper on planes or other public transit or anywhere else. Federal law requires...riiight.
