Markets were boosted this week after the U.S. Court of International Trade said that the 1977 International Emergency Economic Powers Act that Trump cited for ordering massive increases in taxes on imports from around the world does not authorize the use of tariffs.

But the tariffs remain in place for now while the White House appeals the ruling, and the ultimate outcome is still uncertain.

Earlier this week, The court’s ruling also affects only some of Trump’s tariffs, not those on foreign steel, aluminum and autos, which were invoked under a different law.

The Court of Appeals for the Federal Circuit on Thursday allowed the president to temporarily continue collecting the tariffs under the emergency powers law while he appeals the trade court’s decision.
