Trump invoked a zombie statute to justify tariffs on Canada

The world is used to American tariff news daily. A new target is chosen, a new reason is put forward, another legal authority is selected, and a new tariff is put in place, ostensibly to force concessions from a trading partner. But the new tariffs on Canada set a new record for lack of credibility. They invoke a zombie authority found in the notorious and discredited Smoot-Hawley Tariff Act of 1930, which deepened the Great Depression. The courts should reject these tariffs as patently illegal.
