My post on the Recess Appointments Clause was cited in a supplemental letter brief that was filed by the Justice Department in a Recess-Appointments case pending in the U.S. Court of Appeals (page 11, footnote 10).
The letter brief also makes several arguments paralleling what my post said; whether those arguments were taken from the post rather than developed independently, I can’t say. (Though I certainly know what I choose to believe.)
