Relevance to Claims
- CLAIM-008-trump-technate: CONTRADICTS partially. Supreme Court striking down IEEPA tariffs is a significant constraint on Trump’s ability to use emergency powers to rebuild a protectionist Technate. Section 122 also struck down. Trump’s legislative path is much narrower than Jiang assumed.
- CLAIM-012-regional-mercantilism: MIXED. Tariff legal setbacks weaken the US protectionism pillar. But the broader global trend (Hormuz bifurcation, BRICS/West split) continues. Regional mercantilism driven by multiple actors, not just US policy.
