NEW YORK: A divided US appeals court ruled on Friday that most of Donald Trumpâs tariffs are illegal, undercutting the Republican presidentâs use of levies as a key international economic policy tool.
The court allowed the tariffs to remain in place through October 14 to give the Trump administration a chance to file an appeal with the US Supreme Court.
The decision comes as a legal fight over the independence of the Federal Reserve also seems bound for the Supreme Court, setting up an unprecedented legal showdown this year over Trumpâs entire economic policy.
Trump has made tariffs a pillar of US foreign policy in his second term, using them to exert political pressure and renegotiate trade deals with countries that export goods to the United States.
The tariffs have given the Trump administration leverage to extract economic concessions from trading partners but have also increased volatility in financial markets.
Trump lamented the decision by what he called a âhighly partisanâ court, posting on Truth Social: âIf these Tariffs ever went away, it would be a total disaster for the Country.â
He nonetheless predicted a reversal, saying he expected tariffs to benefit the country âwith the help of the Supreme Court.â
The 7-4 decision from the US Court of Appeals for the Federal Circuit in Washington, DC, addressed the legality of what Trump calls âreciprocalâ tariffs imposed as part of his trade war in April, as well as a separate set of tariffs imposed in February against China, Canada and Mexico.
Democratic presidents appointed six judges in the majority and two judges who dissented, while Republican presidents appointed one judge in the majority and two dissenters.
The courtâs decision does not impact tariffs issued under other legal authority, such as Trumpâs tariffs on steel and aluminium imports.
âUnusual and extraordinaryâ
Trump justified both sets of tariffs â as well as more recent levies â under the International Emergency Economic Powers Act. IEEPA gives the president the power to address âunusual and extraordinaryâ threats during national emergencies.
âThe statute bestows significant authority on the President to undertake a number of actions in response to a declared national emergency, but none of these actions explicitly include the power to impose tariffs, duties, or the like, or the power to tax,â the court said.
âIt seems unlikely that Congress intended, in enacting IEEPA, to depart from its past practice and grant the President unlimited authority to impose tariffs.â
The 1977 law had historically been used for imposing sanctions on enemies or freezing their assets. Trump, the first president to use IEEPA to impose tariffs, says the measures were justified given trade imbalances, declining US manufacturing power and the cross-border flow of drugs.
Trumpâs Department of Justice has argued that the law allows tariffs under emergency provisions that authorise a president to âregulateâ imports or block them completely.
Trump declared a national emergency in April over the fact that the US imports more than it exports, as the nation has done for decades. Trump said the persistent trade deficit was undermining US manufacturing capability and military readiness.
Trump said the February tariffs against China, Canada and Mexico were appropriate because those countries were not doing enough to stop illegal fentanyl from crossing US borders, an assertion the countries have denied.
More uncertainty
William Reinsch, a former senior Commerce Department official now with the Centre for Strategic and International Studies, said the Trump administration had been bracing for this ruling. âItâs common knowledge the administration has been anticipating this outcome and is preparing a Plan B, presumably to keep the tariffs in place via other statutes.â
There was little reaction to the ruling in after-hours stock trading.
âThe last thing the market or corporate America needs is more uncertainty on trade,â said Art Hogan, chief market strategist at B. Riley Wealth.
Trump is also locked in a legal battle to remove Federal Reserve Governor Lisa Cook, potentially ending the central bankâs independence.
âI think it puts Trumpâs entire economic agenda on a potential collision course with the Supreme Court. Itâs unlike anything weâve seen ever,â said Josh Lipsky, chair of international economics at the Atlantic Council.
The 6-3 conservative majority Supreme Court has issued a series of rulings favouring Trumpâs second-term agenda but has also in recent years been hostile to expansive interpretations of old statutes to provide presidents newly found powers.
The appeals court ruling stems from two cases, one brought by five small US businesses and the other by 12 Democratic-led US states, which argued that IEEPA does not authorise tariffs.
The Constitution grants Congress, not the president, the authority to issue taxes and tariffs, and any delegation of that authority must be both explicit and limited, according to the lawsuits.
The New York-based US Court of International Trade ruled against Trumpâs tariff policies on May 28, saying the president had exceeded his authority when he imposed both sets of challenged tariffs. The three-judge panel included a judge who was appointed by Trump in his first term.
Another court in Washington ruled that IEEPA does not authorise Trumpâs tariffs, and the government has appealed that decision as well. At least eight lawsuits have challenged Trumpâs tariff policies, including one filed by the state of California.
