A case pitting undocumented college students against the University System of Georgia began Thursday in DeKalb County Superior Court. The case pivots on whether it’s a violation of federal policy to bar the students from top public colleges. The first court appearance concerned one simple question: whether the case should proceed in Fulton or DeKalb County. Speaking to a packed courtroom, Judge Mark Anthony Scott noted a “strong interest” in the case. But he said he needs more time to decide where it should proceed.
