VERNON HILLS, Ill. (WLS) — A prominent toy manufacturer based in Vernon Hills finds itself at the heart of a high-profile legal battle currently unfolding in the U.S. Supreme Court.

The core issue revolves around the extent of a president’s power to impose tariffs without restriction.

During the Supreme Court session on Wednesday morning, a number of justices, including some of the court’s staunch conservatives, expressed doubts about the president’s tariff authority.

Former President Donald Trump has argued that the ability to enforce tariffs is essential for the nation’s survival.

Hand2mind, a company owned by local entrepreneurs, is among the plaintiffs challenging this presidential power.

“There are hundreds and thousands of businesses in the U.S. that are impacted by this policy. They’re impacted either because they they’re manufacturing it, they have to pay tariffs or they’re impacted because they have to buy things. So, people who are out there shopping for Christmas presents right now, maybe noticing that prices are a little higher or inventories a little short,” said Elana Ruffman, vice president of marketing and product development for hand2mind.

The Supreme Court’s decision could cost Americans thousands or trigger tens of billions in refunds.

A ruling is expected before next summer.
