Fallback Tariffs as Executive Tool

A president can resurrect little‑used statutory authorities (e.g., Section 122 of the Trade Act of 1974) to impose near‑global tariffs as a 'fallback' after courts restrict other emergency powers. Such invocations buy short‑term policy space (here 150 days) but create predictable legal, economic, and diplomatic frictions that force follow‑on statutory or negotiating strategies. — If presidents can routinely switch to dormant tariff statutes to skirt judicial limits on other powers, that practice reshapes executive authority over trade, markets, and international relations and will be litigated and politicized rapidly.
