The legality of United States President Donald Trump's global tariffs has come under sharp scrutiny from the Supreme Court.
On Wednesday, the case was examined critically by justices from across the political spectrum, bringing into question the legality of Trump's sweeping global tariffs that he began to implement earlier this year.
Currently, conservatives hold the majority in the Supreme Court, with 6 conservative judges to 3.
The case put forward by the Trump administration relies on a 1977 law, meant for use during national emergencies, giving the President the power to impose the tariffs.
However, the lawyer representing the case was questioned heavily on the legitimacy of the law being used in this case, and whether or not Trump was, in fact, intruding on the powers of Congress instead.
The hearing saw arguments that ran for over two and a half hours, part of the administration's appeal, following a ruling from lower courts that the use of the 1977 law was beyond its authority.
If the Trump administration loses the case, billions of dollars in tariff revenue could have to be refunded.
"The White House is always preparing for Plan B," White House press secretary Karoline Leavitt said before the hearing.
