The Globe and Mail reports in its Saturday edition that the legal war over President Donald Trump's tariffs is far from finished. A New York Times dispatch to The Globe reports that a year after Mr. Trump imposed illegal duties, his administration returned to court Friday to defend a new 10-per-cent tax on most imports. In February the Supreme Court eliminated his original country-by-country rates. He used an old federal law, one never used by previous presidents. This development has triggered a legal battle that could affect Mr. Trump's tariff powers. Despite concerns that the strategy is raising prices for U.S. consumers and businesses, Mr. Trump and his aides maintain that their actions are legal. But state leaders and small businesses have claimed Mr. Trump overstepped, arguing in two lawsuits that the President wrongly bypassed Congress. The final say belongs to a panel of judges on the Court of International Trade, the same specialized circuit that handed Mr. Trump the first in a series of defeats that would upend his initial roster of tariffs. But the administration has projected a sense of optimism that its updated approach is legally sound, as it seeks to avert another recalibration of its trade strategy.
