The Supreme Court has granted an unusually quick hearing on President Donald Trump's sweeping tariffs, setting up a major test of his economic and trade agenda.
The court agreed to take up an appeal from the Trump administration after lower courts found most of his tariffs were illegal.
The small businesses and states that challenged them also agreed to the accelerated timetable.
They say Mr Trump's import taxes on goods from almost every country in the world have nearly driven their businesses to bankruptcy.
The justices will hear the case in November, a lightning-fast timetable by the Supreme Court's typical standard.
The tariffs will stay in place in the meantime.
