Supreme Court Justice Neil Gorsuch issued a dire warning on the dangers arising from federal agencies acting as “prosecutor and judge,” pointing to data showing an alarming trend of cases effectively barred from public jury trials.

In an excerpt of his new book, Over Ruled: The Human Toll of Too Much Law, obtained by the Washington Examiner, Gorsuch criticized how federal agencies not only create and enforce binding rules but also often play the role of both prosecutor and judge. His book follows the most recent Supreme Court term that dealt several blows to administrate agency powers, including the overturning of the Chevron doctrine and a case that limited in-house adjudications at the Securities and Exchange Commission.
