In the circles in which I used to move, the name of Frank Easterbook, a judge on the Seventh Circuit Court of Appeals, is a name to conjure with. A very big noise indeed, especially in conservative legal circles. One of the biggest of the very big noises.
Judge Easterbrook has just reamed out Bill Barr—who most assuredly needs a good reaming, and who has been begging for it. See Politico, A Conservative Judge Draws a Line in the Sand With the Trump Administration: Outraged the attorney general had ignored a court order, he authors a blistering opinion rebuking William Barr for overstepping his constitutional authority.
Or read the opinion yourself. You might check out the language I have emphasized, beginning at page 3 of the 7 page opinion.
