(AP) Idaho has delivered arguments to the Idaho Supreme Court on why justices should reject a  lawsuit filed by Twin Falls County aiming to have the state’s new legislative boundaries thrown out. Twin Falls County argues the county-splitting map approved Oct. 14 disadvantages its voters.

Idaho counters the plan meets the one-person, one-vote requirement, splits counties only where necessary and joins similar communities. According to the filing, redistricters crafted a plan that’s legally defensible and meets Idaho’s best interests. Secretary of State Ben Ysursa said Tuesday he’s hopeful justices will rule soon after a scheduled Jan. 5 hearing, to give Idaho election officials time to prepare for the May 15 primary. A second, separate lawsuit, filed by northern Idaho counties, is due for oral arguments in state Supreme Court on Jan. 19.
