The rule, from the Department of Justice and Homeland Security, prohibits migrants who have lived or emigrated to third countries from seeking asylum in the US, thus prohibiting people traveling to Mexico from asylum claims.
Justices Sonia Sotomayor and Ruth Bader Ginsburg noted their disobedience. Five justices are required to grant the request; the votes of others have not been made public.
"The Executive Branch again issued a policy aimed at raising long-term practices regarding refugees seeking refuge from persecution," Sotomayor, accompanied by Ginsburg, later points out to "some of the most vulnerable people in the Western Hemisphere."
"Although this country has long maintained the refugee door – and although the stakes for asylum seekers cannot be higher – the Government enforced its rule without first providing it public notice and invited public input as is usually required, "Sotomayor added.  The Supreme Court's order is the latest move in a case bouncing between lower courts.
In the midst of back and forth, the Department of Justice asked the Supreme Court to enter.
In his distinction, Sotomayor criticized both the implementation of the new regulation and the majority for deciding before the 9th Circuit could fully resolve The government's emergency request to uphold the district court's order.
"The court," Sotomayor wrote, "is a step in the ordinary judicial process."
Steve Vladeck, CNN Supreme Court analyst and professor at the University of Texas School of Law, agreed that the reasons allowed the administration to "jump in the queue."
"Again, the Supreme Court has allowed a controversial Trump administration policy to be similar even if legal challenges to the law continue through lower courts," Vladeck said.
The Trump administration is strictly critical of what it sees as a relatively new judicial circuit in which a single district judge has halted a nationwide policy before. it can separate the lower courts and reach the Supreme Court.
He said that national injections, created an "unequal, one-way system through which democratic accountability of the government should save on a case-by-case basis in order to carry out its policy, while policy challenges you just need to find a sympathetic judge. "
The American Civil Liberties Union said in a statement that it would continue to challenge the rule. "We continue to challenge the ban on merits, because it puts countless lives at risk," said ACLU attorney Lee Gelernt.
