More than 100 companies have filed lawsuits challenging President Trump's global tariffs after the Supreme Court declared most of them illegal, with legal experts estimating the total could reach 2,000 cases. The litigation surge reflects mounting frustration over the administration's reluctance to refund the billions in tariffs already collected from businesses.

The legal battle stems from Trump's aggressive trade policies, which imposed sweeping tariffs on imports from China and other trading partners. Companies argue they've been unfairly burdened by these duties, which the Supreme Court found exceeded presidential authority. The administration has collected billions of dollars in tariff revenue, creating a massive pool of disputed funds.

Business groups warn the litigation could drag on for years, creating uncertainty for companies trying to recover costs. Legal experts say the sheer volume of cases suggests a coordinated industry pushback against what many view as an overreach of executive power. The outcome could have significant implications for future trade policy and presidential authority over tariffs.
