Wichita ? The lawsuit filed by a Wichita mathematician seeking voting machine tapes after finding statistical anomalies in election counts is set to go to trial early next year.

A scheduling order issued Monday sets a one-day bench trial for March 22 to hear the open records case brought by Wichita State University statistician Beth Clarkson.

Sedgwick County Judge Douglas Roth also set deadlines for motions and scheduled a Jan. 14 pretrial conference.

Clarkson wants the tapes to do a statistical model by checking the error rate on electronic voting machines used at a Sedgwick County voting station during the November 2014 general election.

Top election officials for Kansas and Sedgwick County want the court to block the release of tapes, arguing they are not subject to the open records act.
