A new lawsuit filed in federal court on April 4 seeks to compel federal officials to keep a pandemic-era order in place to help manage the crisis at the U.S. Mexico border.

If the Biden administration is allowed to rescind the Title 42 order next month, it will lead to a spike in illegal immigrants flooding across the border, the new suit asserts.

“Defendants’ unlawful termination of the Title 42 policy will induce a significant increase of illegal immigration into the United States, with many migrants asserting non-meritorious asylum claims,” the attorneys general of Arizona, Louisiana, and Missouri, who brought the suit, said in the filing.
