By EditorApr 14, 2021

Ohio’s Lawsuit Over Census Data Delay is Dismissed by Federal Court

By EditorMar 24, 2021
Earlier today, the U.S. District Court for the Southern District of Ohio denied Ohio's request to the court for an order compelling the U.S. Census Bureau to deliver redistricting data to the state by the statutory deadline of March 31. Ultimately the court denied the request for a preliminary injunction for lack of standing because the Census Bureau's failure to meet its deadline in and of itself does not constitute a redressable injury, explaining that "A litigant is not concretely injured and standing is not met simply because a statute creates a legal obligation that goes unfulfilled." In an opinion…

By Jeffrey M. WiceMar 24, 2021
