It’s back to the drawing board for creating legislative districts in Idaho. The Idaho Supreme Court has ruled 4-1 against the state’s second legislative redistricting plan. The Plan was developed by Idaho's second bipartisan redistricting commission. The court found that since the plan's unconstitutional, it “must be revised,” The plan was challenged by Twin Falls County, which said the plan was unconstitutional because it unnecessarily split counties. Idaho's legislative district boundaries are redrawn once every 10 years to reflect population changes following the U.S. census. The court’s justices could have redrawn the districts themselves but  chose instead to send the plan back to the commission to amend.
