The lawsuit, filed late on Monday, was the first to challenge President
Donald Trump over asylum since the U.S.
Supreme Court decided last week that an anti-asylum rule will be allowed to take effect while a separate lawsuit on its underlying legality is heard. Unlike other suits that have targeted the asylum rule itself, the latest filing challenges the Trump administration on procedural grounds, saying the government has enacted changes without warning, resulting in elevated rejection rates for asylum-seekers. With the administration rolling out a series of anti-immigration regulations in rapid succession, asylum-seekers are not being told which of the shifting standards will apply to their cases, said Hassan Ahmad, the lead attorney on the lawsuit.
