The legal confusion over tariffs has buffeted U.S. trading partners around the world, casting doubt on the durability of Trump’s favorite bargaining tool.

India is reviewing the impact of a US court ruling that blocks President Donald Trump from imposing sweeping tariffs on imports, sources said. The US court found the 1977 International Emergency Economic Powers Act, which Trump has cited as his basis for ordering massive increases in import duties, does not authorise the use of tariffs.

Indian trade negotiators are “studying the implications” of the US Court of International Trade that has significantly curbed US President Donald Trump to impose sweeping tariffs as US trade negotiators are set to arrive in India for two-day talks on June 5 and 6, a senior government official said on Thursday.
