Businesses Learning Resources Inc. and hand2mind Inc. filed a petition with the Supreme Court on Tuesday, attorney Pratik Shah confirmed to Forbes, which asks the high court to consider whether Trump’s “Liberation Day” tariffs are lawful under the International Emergency Economic Powers Act (IEEPA), the law the president used to impose them.

The Supreme Court on Tuesday received its first request to consider whether President Donald Trump’s tariffs are constitutional. Two educational toy companies, Learning Resources and hand2mind, urged the justices to immediately take up their case rather than letting it play out in the lower court.
