Peterson's attorneys were in Twin Falls County's 4th District Court on Tuesday. They are representing Peterson in a lawsuit he brought against two party officers to maintain control of Idaho's divided GOP.
Those defending the officers say Peterson no longer is the party chairman because his two-year term ended when the GOP convention adjourned earlier this year without electing a new leader. The officers scheduled a meeting on Aug. 2 to elect a new leader.
Peterson contends that that action was illegal under the party rules, despite the Republican National Committee endorsing the meeting.
Instead, Peterson has scheduled an Aug. 9 meeting to determine party leadership.
