WESLACO - A federal judge blocked an asylum policy known as the Third-Country Rule.

A judge in California made the decision today.

This policy was in place in the Rio Grande Valley.

It requires asylum seekers heading to the U.S. to first request asylum from other countries they pass through.

The CBP acting commissioner Mark Morgan told NPR in July that this rule was piloted in the Rio Grande Valley.

On Monday the court established a nationwide injunction meaning it can't be applied throughout the country.

Morgan expressed frustration and called the decision "judicial activism."

"The unprecedented judicial activism that we experience every single time that this administration comes up with what we believe is a legal rule or policy that we really believe that will address this crisis, we end up getting enjoined. It's very, very frustrating. But, we're just going to keep going," says Morgan.

The judge ruled to have the injunction expand the whole country for uniformity policy, even enforcement and in situations when the agency's actions are found not to be in accordance with law.

During the same press conference, Morgan announced the numbers of migrants detained at the border are down significantly since May.

The policy credited with vastly reducing the number of migrants released to the United States is the migrant protection protocol.

That is currently still in place.

So far, over 40,000 migrants have been returned to Mexico under its implementation.
