In a set of opinions that spans more than 90 pages, took more than seven months to write, references places from Liberia to Cuba to Taiwan to Montreal to Hispaniola, and then ranges across U.S. history from Alexander Hamilton to George W. Bush, the Supreme Court’s opinion in a much-awaited presidential powers case, Zivotofsky v. Kerry, proves that when it comes to frolicking in the deep end of text, history, and statutory construction, nobody does it like a justice does it. By a 6–3 margin, with Justice Anthony Kennedy joining with the court’s liberals and—in part—Justice Clarence Thomas, the court found that Section 214(d) of the Foreign Relations Authorization Act was unconstitutional.
