President Donald Trump's tariffs suffered a "big blow" in court on Friday, and critics could not hide their satisfaction.

A federal appeals court ruled Trump had no legal right to impose sweeping global tariffs using emergency authority, finding those tariffs unconstitutional. However, the court left the tariffs in place temporarily while the matter is appealed further, likely to the Supreme Court.

The ruling largely upheld a May decision by a specialized federal trade court in New York. It comes as experts warn of "staggering" price hikes that could hit Americans.

CNN's Jake Tapper called it a "big blow" on air to Trump's agenda. New York Times reporter Maggie Haberman told Tapper the same during a brief interview after the ruling dropped.

Reaction was swift across the internet.

Frank Amari‪, a former public defender, joked on Bluesky, "So much winning!!"

Historian and writer Trent Nelson wrote on Bluesky, "Yea. Obviously."

Economist Justin Wolfers‪ cheered the ruling on Bluesky, but warned the fight isn't over.

"BOOM. The federal appeals court rules Trump's tariffs illegal, because they are. There's no national emergency, and so the power to tariff a country rests with Congress. Trump admin has lost at every stage of the process, but stay tuned for the Supremes to chime in."

He noted, "This won't end all tariffs. This ruling applies to tariffs applied to entire countries (which is most of the tariff agenda). The industry-specific tariffs use a different legal authority, and will remain. The White House has other (more limited) tariff powers it'll dust off."

Dmitry Grozoubinski‪, author of "Why Politicians Lie About Trade," wrote on Bluesky, "Appeals court says Trump's fentanyl and reciprocal tariffs are unlawful. Looking forward to the 6-3 SCOTUS decision which upholds them anyway because the Constitution clearly states Trump is an omnipotent God-Emperor destined to reign upon the Golden Throne until all is returned to dust."

Analyst and writer Christian Roselund‪ wrote on Bluesky, "This is the second court ruling to affirm that #Trump 's use of the International Emergency Economic Powers Act (IEEPA) to set sweeping, economy-wide tariffs is illegal. The Trump Admin will almost certainly appeal. Not sure what the next stop is."
