The same court decided to keep another major change on hold, one that denies asylum to anyone who enters the US illegally from Mexico.Opponents, including the American Civil Liberties Union, argued that the administration violated US law and obligations to international treaties by turning back people who will likely be persecuted because of their race, religion, nationality or political beliefs.
Its expansion coincided with a sharp drop in Border Patrol arrests from a 13-year high in May, suggesting it may have had its intended effect.Opponents say it has exposed asylum seekers to extreme danger in violent Mexican border cities while they wait for US court hearings. The policy was introduced at the border crossing in San Diego in January and initially focused on asylum seekers from Guatemala, Honduras and El Salvador.
