The Costa Rican Supreme Court ruled that illegal immigrants deported to the country by the United States must be released.

In February, Costa Rica accepted deportation flights totaling around 200 migrants after pressure from the Trump administration. The group was taken to the Temporary Migrant Care Center, a temporary shelter, close to the border with Panama, where they were made to stay or leave for their home countries. On Thursday, in a 4-3 vote, the Central American nation’s highest court ruled that the 28 remaining migrants must be released.
