Neal Katyal, the American lawyer credited with securing a major Supreme Court setback for US President Donald Trump’s tariff policies, has a long record of high‑profile legal victories, including a Supreme Court case defending a Guantanamo Bay detainee who was once Osama bin Laden’s driver.
55-year-old Katyal argued before the United States Supreme Court this week on behalf of small businesses and trade associations challenging Trump’s sweeping tariff actions. The court ruled 6‑3 that the president lacked authority to impose broad tariffs without explicit congressional approval, reaffirming constitutional limits on executive power.
