Supreme Court Curbs Trump's Tariff Powers, Reasserts Constitutional Limits

• The US Supreme Court rejected Trump's claim of unbridled power to impose and remove tariffs, setting new limits on presidential authority.
• The 6-3 ruling, with three Republican appointees in the majority, emphasized constitutional boundaries and faulted Trump for seeking a "transformative expansion" of power.
• This decision signals the justices will not be a "rubber stamp" for Trump's actions, despite largely accommodating his administration in the past year.
• Chief Justice John Roberts highlighted that the Constitution grants taxing power to Congress, not the executive branch, broadening the clash over the 1977 emergency-powers law.
• The ruling also invoked the major questions doctrine, requiring clear congressional authorization for far-reaching executive actions, applying it to Trump's tariffs.
