The U.S. Supreme Court saw a rare personnel change in the past year, as Associate Justice Neil Gorsuch took the seat vacated when Antonin Scalia died in 2016.

Ilya Shapiro, senior fellow in constitutional studies at the libertarian Cato Institute and editor-in-chief of the Cato Supreme Court Review, used a presentation Wednesday to the Triangle Lawyers Chapter of the Federalist Society to detail Gorsuch’s impact and analyze other key developments during the high court’s 2016-17 term.
