A federal judge found no probable cause to believe that the migrants knew they were entering a military zone and thus “willfully” trespassed onto land the Trump administration declared “national security areas” earlier this month.

Chief U.S. Magistrate Judge Gregory Wormuth began filing the dismissals late on Wednesday, ruling that migrants did not know they were entering the military zone in New Mexico and therefore could not be charged, according to court documents and a defense attorney.

A federal judge has dismissed trespassing charges against nearly 100 migrants arrested along the Mexican border under a policy from the Trump administration.
