In a significant ruling, the US Supreme Court announced its decision against former President Donald Trump's global tariffs, which he had sought to implement without congressional approval. Six of the court's nine justices sided with businesses from twelve predominantly Democrat-led states that challenged the president's tariffs. The businesses argued that these country-specific taxes were not imposed following the lawful process, which traditionally requires congressional action, thus highlighting a major constitutional conflict between executive powers and legislative authority.

The court's judgment emphasized that the US Constitution explicitly entrusts Congress with the responsibility for taxation, stating that the framers 'did not vest any part of the taxing power in the executive branch.' This ruling not only represents a significant legal defeat for Trump but also emphasizes the critical checks and balances that exist within the framework of US governance, particularly concerning economic and tax policy decisions.

President Trump expressed his disappointment, labeling the justices who voted against him as lacking the bravery to do what he deemed was right for the country. This ruling has broader implications for future presidential actions concerning economic policy, as it reinforces the principle that significant measures like tariffs cannot circumvent the legislative process, potentially shaping how future administrations approach similar issues in light of constitutional constraints.
