U.S. District Judge Daniel Hovland granted a temporary injunction last July that blocked the law from taking effect in August.
The New York-based Center for Reproductive Rights is representing Fargo's Red River Women's Clinic. The center filed the lawsuit after the law was passed last year by the North Dakota Legislature. The law outlaws abortions as early as six weeks into pregnancy and before some women even know they are pregnant.
A spokeswoman for the center says a ruling from the bench is unlikely Friday, but that one could come in a couple of weeks.
