'Incredible': Expert warns Trump admin just signaled 'open defiance' of Supreme Court

The Trump administration is flagrantly ignoring a directive from the Supreme Court, a prominent immigration rights attorney warned Thursday afternoon.

The revelation came from a court document that revealed the Trump administration plans to slash the amount of time people have to seek federal relief before being subject to immediate deportation.

"BREAKING: The US is now only giving migrants 12 hours to decide whether they want to contest under the wartime authority, Alien Enemies Act, down from 24 hours," wrote Valerie Gonzalez, an Associated Press reporter covering border security issues, in a post on X. She added that "the government attempted to seal the document but judge just unsealed it."

This order alarmed attorney Aaron Reichlin-Melnick of the American Immigration Council.

"WOW. This is incredible. It signals open defiance of the Supreme Court, which ruled that the government MUST give people 'reasonable time' to be able to 'actually seek habeas relief' — to be able to ACTUALLY, not theoretically, sue. 12 hours is not enough for that. Period," wrote Reichlin-Melnick.

The standard notice the government will send not only gives people just 12 hours, but doesn't even inform them of their rights, he noted.

"This is an important part of understanding why DHS's process is openly defiant of the Supreme Court, which said notice 'must be afforded ... in such a manner as will allow them to actually seek habeas relief.' This notice doesn't even MENTION court!" he wrote. "Also, the DHS notice is entirely in English and does not even mention the POSSIBILITY of challenging the designation as an 'alien enemy,' so how would anyone even know to tell DHS within 12 hours?! The closest thing on here is a bit saying a person can 'make a phone call.'"

There isn't even a box on the form they can check to request a hearing, Reichlin-Melnick added.

"Nothing on the form would give any person the idea that they can go to a DHS agent and say 'I am formally opposing this, please delay my removal for 24 hours so I can file a habeas corpus lawsuit.' It's just a ridiculous claim by ICE officials."

Trump's administration has increasingly come under fire for clashing with courts over their ability to conduct mass deportations to a foreign megaprison in El Salvador, with one of the most prominent cases being a Maryland father who was disappeared overseas despite a protective order barring his removal to that country.
