EL PASO, Texas (Border Report) — A federal judge in Louisiana ruled Friday that the Biden administration must continue expelling migrants at the border under Title 42.

Title 42 is the World War II-era public health order that prohibits entry into the United States if the Centers for Disease Control and Prevention believes it could introduce communicable diseases into the country.

Invoked at the start of the coronavirus pandemic in March 2020, Title 42 has allowed U.S. Border Patrol agents and U.S. Customs and Border Protection officers to immediately expel migrants from the U.S. without giving them a chance to request asylum.

As of the end of April, migrants have been expelled under Title 42 order more than 1.9 million times.

Because the migrants face expulsion without a record of the removal, many attempt to cross more than once, officials say.
