The Supreme Court invalidated an injunction set by the lower courts on Wednesday and will allow the Trump administration to continue holding migrants in Mexico who show up at the border and attempt to gain asylum.

SCOTUS has saved the Migrant Protection Protocols (MPP), at least temporarily, from being ended by left-wing judicial activism. The Trump administration policy has kept tens of thousands of migrants in Mexico, which has helped to combat the national emergency at the border caused in part by the migrant caravans funded by the likes of George Soros.

However, there are still lawsuits that are active to defeat the common-sense policy, as the court battle against the MPP continues. A Justice Department agreed with the decision, saying that SCOTUS saved a policy that is “critical to restoring the government’s ability to manage the Southwest border.”

The extremists at the American Civil Liberties Union (ACLU) are angry that SCOTUS is allowing the Trump administration to protect the border. Judy Rabinovitz, a top attorney with the ACLU who is also the Deputy Director of the group’s Immigrants’ Rights Project, said the MPP is an “illegal” policy and whined that migrants “face grave danger and irreversible harm every day this depraved policy remains in effect.”

Previously, the MPP was under assault by the lower courts. An appeals court panel in San Francisco, Calif. made a 2-1 ruling to issue an injunction against the MPP last month.

U.S. Circuit Judge William Fletcher, a Clinton-era appointee, opined in his ruling that he had seen “uncontested evidence” showing that migrants “risk substantial harm, even death, while they await adjudication of their applications for asylum.” That ruling is no longer valid because of the SCOTUS decision.

The open borders proponents have been rebuked by SCOTUS, and the Trump administration will be allowed to stop the migrant invasion at least for the time being.
