Youngstown Sheet and Tube Co. v. Sawyer, famously known as the Steel Seizure Case, is a landmark decision that belongs in the pantheon of great constitutional law cases. The case generated high political drama, sharp legal conflict, and tides of public opinion, with the U.S. Supreme Court facing issues of surpassing importance for a nation committed to the rule of law. The defining issue in the case—whether the president possesses an inherent or emergency power to seize control of an industry, such as the steel mills, in the midst of a crisis—compelled the Supreme Court to engage in the most penetrating examination of executive power in the country’s history.
