On April 7, 2023, Katsas authored a dissent in Fischer v. United States, a case interpreting whether January 6 participants could be charged under 18 U.S.C. § 1512(c), a provision of the Sarbanes–Oxley Act enacted to combat corporate fraud that penalizes anyone who “otherwise obstructs, influences, or impedes any official proceeding.” Rejecting the government's argument, Katsas argued that interpreting “the structure and history of section 1512, and with decades of precedent applying section 1512(c) only to acts that affect the integrity or availability of evidence” suggest that the government's reading is “implausibly broad and unconstitutional in a significant number of its applications.” and also a member of the American Academy of Appellate Lawyers.
Awards In 2009, he was awarded the Edmund Randolph award for outstanding service, the highest award bestowed by the United States Department of Justice.
