On Wednesday, the U.S. Supreme Court made a shocking decision on immigration, giving Joe Biden’s administration a win over its attempt to suspend 45th President Donald J. Trump’s “remain in Mexico policy.

According to SCOTUSBlog, “The Supreme Court ALLOWS the Biden administration to terminate the controversial Trump-era asylum policy known as ‘remain in Mexico.’ Red states argued that Biden was obliged to keep the policy, but SCOTUS says in a 5-4 ruling that the administration can end it.”

The Biden administration has been trying to dismantle the agreement made by Trump and Mexico, which has helped quell illegal immigration into America.

According to Fox News:

Under that policy, migrants seeking entry into the U.S. had to stay in Mexico as they awaited hearings. The Trump administration put the policy in place so that migrants would not be released into the U.S. The Biden administration had tried to repeal the policy but was previously blocked by a lower court.

At issue was whether the Department of Homeland Security’s suspension and subsequent termination of the policy violated a federal law that requires that migrants be detained or, if they arrived from a contiguous country, sent back.

The key statute is 8 U.S.C. Section 1225, part of which says someone applying for admission “shall be detained for a proceeding” unless they are “clearly and beyond a doubt entitled to be admitted,” and part of which says if they are from a contiguous territory like Mexico, “the Attorney General may return the alien to that territory” as they await a hearing.

Without the ability to detain everyone, Texas and Missouri argued in their lawsuit, sending them back when possible is necessary.

Since Biden took office, the U.S. has seen some of the highest levels of illegal immigration in years through the Southern Border.
