On Friday, the U.S. Supreme Court delivered a significant ruling that limits President Donald Trump's authority to impose tariffs based on the grounds of national emergencies. The decision explicitly states that the president can no longer use the International Emergency Economic Powers Act (IEEPA), which previously granted him extensive powers to regulate economic actions following a national emergency declaration. This ruling comes as a setback for Trump, who has relied on such measures to assert his trade policies, effectively stripping him of a key tool in his arsenal to leverage trade negotiations.

Yle's U.S. correspondent, Ilmari Reunamäki, highlights the implications of this ruling, indicating that it compels Trump to adapt his tariff policies to be more predictable and acceptable to the public. Although the ruling is likely to frustrate Trump, who has often utilized tariffs as a means of exerting control over international trade and asserting national interests, it may ironically lead to a more favorable reaction from the American populace, who prefer transparency and predictability in trade matters.

In summary, the Supreme Court's decision is a pivotal moment in Trump's trade policy, with potential repercussions on both domestic and international fronts. As the president re-evaluates his approach to tariffs and economic regulation, the focus will shift towards how his administration manages international relations amid these new legal constraints, especially with an electorate that values clarity and accountability in governance.
