Three cities have filed an emergency application with the Supreme Court, seeking to overturn a legal agreement that halted a federal immigration regulation. The dispute centers on a Biden-era rule that was challenged by the state of Texas in June. On the same day the lawsuit was filed, the Department of Justice conceded that the regulation was unlawful, leading a federal judge to immediately block its implementation.

The petitioning cities characterize this rapid sequence of events as "egregious collusion" between the state of Texas and the federal government. They argue that the administration effectively abandoned the defense of its own policy without a proper legal contest, bypassing the standard judicial process. By settling the case so quickly, the cities contend that the federal government deprived them and other stakeholders of the opportunity to defend the regulation in court.

The core of the conflict lies in whether the Department of Justice acted within its authority to concede the case or if the maneuver was a strategic effort to bypass administrative requirements. While the federal government and Texas maintain the settlement was a standard resolution to a legal challenge, the cities are asking the Supreme Court to step in and revive the rule, arguing that the process used to invalidate it was fundamentally flawed and lacked transparency.
