WASHINGTON (Reuters) -The U.S. Supreme Court declined on Friday to speed up its consideration of whether to take up a challenge to President Donald Trump's sweeping tariffs even before lower courts have ruled in the dispute.

The Supreme Court denied a request by a family-owned toy company, Learning Resources, that filed the legal challenge against Trump's tariffs to expedite the review of the dispute by the nation's top judicial body.

The company, which makes educational toys, won a court ruling on May 29 that Trump cannot unilaterally impose tariffs using the emergency legal authority he had cited for them. That ruling is currently on hold, leaving the tariffs in place for now.

Learning Resources asked the Supreme Court to take the rare step of immediately hearing the case to decide the legality of the tariffs, effectively leapfrogging the U.S. Court of Appeals for the District of Columbia Circuit in Washington, where the case is pending.

Two district courts have ruled that Trump's tariffs are not justified under the law he cited for them, the International Emergency Economic Powers Act. Both of those cases are on appeal. No court has yet backed the sweeping emergency tariff authority Trump has claimed.
