One of Trump's lifetime appointed judges (who the ABA ranked as totally unqualified) blocked the CDC mask mandate. For all of the wrong reasons.

How a Trump-appointed judge reignited a major debate over power in the courts
Are we comfortable placing such power in the hands of individual, unelected district judges — especially in an age when the federal courts often look just as polarized as the country?

On Monday, Tampa, Florida-based federal District Judge Kathryn Kimbell Mizelle threw out the mask mandate the Centers for Disease Control and Prevention had imposed on all interstate transportation hubs — including commercial airports and airplanes — to suppress the spread of Covid. Mizelle’s analysis, such as it is, focused on two distinct holdings — that the CDC lacked the statutory authority to impose such a mandate (because wearing a mask is unrelated to “sanitation,” a dubious piece of statutory interpretation, to say the least) and that, in any event, the CDC had taken procedural shortcuts in adopting the mandate that also rendered it invalid. Because her decision purports to vacate the entire CDC rule, it has nationwide effect — meaning that, by Monday afternoon, most major airlines and transportation services were no longer enforcing mask requirements.
