Delegated.

A manufacturer of vaping liquid, invoking the structural limitations imposed on administrative agencies by the delegation doctrine, challenged the FDA’s power to regulate it. The Fifth Circuit observed: “The [Supreme] Court might well decide—perhaps soon—to reexamine or revive the nondelegation doctrine. But ‘[w]e are not supposed to . . . read tea leaves to predict where it might end up.'” (citation omitted). That observation was case-dispositive: “The [Supreme] Court has found only two delegations to be unconstitutional. Ever. And none in more than eighty years.” Under that precedent, Congress’s delegation of authority to the FDA in this area showed a “sufficiently intelligible principle,” constrained by Congress’s definition of “tobacco product,” and by Congress having “ma[de] many of the key regulatory decisions itself.” Big Time Vapes, Inc. v. Food & Drug Admin., No. 19-60921 (June 25, 2020).
