A federal magistrate judge recommended this month the dismissal of a lawsuit challenging the immigration program in place at the Hall County Jail, according to court documents.. Nicholas Montalvan Ceballos and Jose Santos Delgado, both represented by Gainesville attorney Arturo Corso, were the plaintiffs in a habeas corpus petition regarding the 287(g) program. Hall County entered the program in 2007, a partnership with Immigration and Customs Enforcement at the local law enforcement level.
