Guest columnist Gary J. Simson—Macon Chair in Law at Mercer Law School and Professor Emeritus at Cornell Law School—critiques executive orders issued by President Donald Trump that punish specific law firms for their clients or past actions, arguing that these orders resemble historically condemned legislative punishments known as bills of attainder. Professor Simson contends that these orders are fundamentally unconstitutional assaults on the legal system and should be challenged under the Constitution’s Bill of Attainder Clause, which was designed to prevent exactly such abuses of power.
