A federal judge granted a motion on Friday to expand the class definition in a class action lawsuit against the Immigration and Custom Enforcement agency.

In the original complaint, the plaintiff, Ms. L, sought to reunite with her seven-year-old daughter after they both fled violence from the Democratic Republic of Congo. Upon seeking asylum in the US, the two were separated.

After the Department of Justice and Attorney General announced their zero-tolerance policy against undocumented immigrants crossing the border, mass amounts of parents and children were separated from one another. The plaintiffs in the class action were granted an injunction to prevent the Department of Homeland Security from separating families while making efforts to reunite those impacted by the Attorney General’s orders.

The petitioners sought to expand the definition in the class categorization to include families released by the Office of Refugee Resettlement before the injunction was granted. Following the Office Of Inspector General report on the impact of the zero-tolerance policy, thousands of families were impacted, but would not have been included in the original class certification of the lawsuit and injunction.
