This article from NBC says this (emphasis mine):
A three-judge panel of state judges issued an order Monday barring state officials from using the current map for the coming elections, including the March presidential primary. The panel stopped short of ordering the legislature to draw new maps but said disruptions could be avoided "should the General Assembly, on its own initiative, act immediately and will all due haste to enact new congressional districts."
What is the distinction here? What does it mean that they didn't tell the assembly to redraw maps, but they also threw them out?
