The justices will hear arguments Wednesday on the legality of most of the president’s tariffs — the first in a series of tests of sweeping claims of authority.

US President Donald Trump will not attend the Supreme Court's high-stakes hearing on Wednesday, 5 November, which could determine the legality of his sweeping global tariffs, Reuters reported.

As of September 23, American businesses have paid nearly $90 billion to cover the IEEPA tariffs being challenged, according to US Customs and Border Patrol data.
