American small businesspeople likely let out a collective gasp at the Supreme Court’s rejection of President Donald Trump’s tariff regime. Justices on Feb. 20, in a 6-3 decision, struck down the president’s sweeping tariffs. The ruling marked an extraordinary rejection of both his signature economic policy and the lever of power he’s used to bend the global economy to his will.

Among other adverse consequences, the Trump tariffs have, from the start, made business planning difficult. The threat and reality of tariffs have been around since Day One of Trump’s second, nonconsecutive term, over a year ago. So, it might have seemed that there would be a much clearer picture of how such a policy could be affecting the economy, particularly for small- to medium-sized businesses.
