The 11th Circuit is one of the most conservative federal appeals courts in the country, with seven judges appointed by Republican presidents and four by Democrats. It sets precedent for much of the Southeast. Any ruling it makes could be appealed to the Supreme Court.
If that happened, what the justices would do is also not clear. They have ruled against some Biden administration pandemic policies. For instance, the court said the CDC did not have the power to extend an eviction moratorium to prevent the interstate spread of disease. The Biden administration also lost a challenge to a rule that set vaccinate-or-test requirements for large employers’ workers. However, the court upheld the administration’s vaccine requirement for healthcare workers.
“It’s not like there is a clear path that the Supreme Court would take the government side on this,” said Fuse Brown. “But enough people say the risk is worth taking because right now the CDC is neutered.”
Experts also pointed out that because of how the judge’s decision was developed, the dictionary could become a star witness in future proceedings.
In her ruling, District Court Judge Kathryn Kimball Mizelle, an appointee of President Donald Trump’s, spent several pages discussing the meaning of “sanitation.”

That word is part of the Public Health Service Act of 1944. It says the surgeon general has the power to make regulations deemed necessary to prevent the spread of communicable diseases. The statute goes on to suggest several ways of doing that, including “disinfection,” “fumigation,” and, Mizelle’s focus, “sanitation.”
Mizelle’s decision said her court researched present and historical dictionary definitions of the word and selected one. Mask-wearing, Mizelle said, did not meet that narrow definition because it “cleans nothing.” (She rejected another definition, which meant to keep something clean, which might have included wearing protective masks.)
Her definition could be challenged, said Lawrence Gostin, who is a professor and directs the O’Neill Institute for National and Global Health Law at Georgetown University. “If you look at the historic meaning in 1944 and before, sanitation was for hygiene and public health,” said Gostin.
Even some critics of the mask mandate, such as Somin, said Mizelle’s definition of “sanitation” may be too narrow. It would also preclude, he noted in a blog post for Reason magazine, a hypothetical CDC ban on “defecation” on the floor of a bus or airplane, since such a ban “does not clean anything.”
Other elements of the public health statute create potential lines of argument, particularly a part saying government health officials can take “other measures” they deem necessary.
The Justice Department is likely to make the case that a mask mandate for interstate travel clearly fits into this category, said Hodge. But that would require the Biden administration to convince the court that Mizelle’s decision was a “gross misinterpretation” of statutory law.
“If they nailed it on that, they could win the case straight up,” Hodge said.
Not so fast, said Somin.
The law should be read in a way “narrow enough to avoid giving the CDC power to restrict virtually any human activity that might potentially spread disease – which the Supreme Court (correctly) ruled is unacceptable” in the eviction moratorium case, he wrote in another recent blog post.
A second, very separate statute could also come into play.
One of the wonkiest elements of Mizelle’s decision is her assertion that the government failed to follow the Administrative Procedure Act, a law that spells out how the federal government is to go about creating rules, including a requirement that it generally seek comments from the public on a proposed rule for at least 30 days. The mask rule was advanced without a public comment period.
“This is the strongest argument against the government in this case,” Somin said.
The government has maintained that it had to move fast as the pandemic raged and that it is allowed a “good cause” exemption in such circumstances.
Deaths from COVID in January 2021 were at record highs when the mask order was put forth, averaging more than 3,000 a day, and new variants were springing up.
The order took effect on Feb. 1, 2021.
Now, it all comes down to “either the CDC has the power or it doesn’t,” said Gostin. “It’s hanging like a black cloud over the CDC. They want to get a ruling. ”
