• Supreme Court schedules November 5 for arguments on Trump's tariffs.
• Challenges from small businesses and 12 states claim Trump overstepped authority.
• Tariffs remain in effect during the appeal process.
• The case tests Trump's use of emergency powers to levy import taxes.
• Lower courts have aligned with challengers but upheld most tariffs.

The U.S. Supreme Court has announced that it will hear arguments on November 5 regarding the legality of President Donald Trump's sweeping tariffs. This case represents a significant examination of Trump's assertion of executive power, which has been a cornerstone of his trade agenda. The court's decision follows a ruling by a lower court that found Trump had exceeded his authority under a federal law intended for emergencies, according to Newsweek, Reuters, and Channel News Asia.

This legal challenge has been brought forth by small businesses and 12 states, primarily governed by Democrats, including Arizona, New York, and Colorado. These challengers argue that the tariffs have pushed them to the brink of collapse. The Supreme Court will also consider a separate case filed by the family-owned toy company, Learning Resources, regarding the tariffs, as noted by Reuters and Channel News Asia.

Despite the ongoing legal proceedings, the tariffs remain intact, a fact emphasized by the courts during the appeal process. The U.S. Court of Appeals for the Federal Circuit recently upheld the tariffs while marking Trump's invocation of the International Emergency Economic Powers Act (IEEPA) as overreach. This law, traditionally applied to sanctions and asset freezes, had never been used for imposing tariffs before Trump, according to Newsweek and Channel News Asia.
