A discovery recount will begin Monday but won't likely end until the first full week in May for the Republican nomination for circuit judge in Kane County.
Geneva attorney D.J. Tegeler holds a seven-vote lead over Associate Judge Marmarie Kostelny for the GOP nomination.
The results of the March 18 primary election were certified by state officials last week and Kostelny asked for a discovery recount, which will include 25 percent of precincts.
The first part of the recount will be held Monday afternoon at the Aurora Election Commission Offices.
Linda Fechner, the commission's executive director, said two precincts will be counted again.
In nine total precincts in Aurora, Kostelny edged Tegeler by 69 votes.
On May 5, officials at the Kane County clerk's office will begin recounting 16 precincts specified by Kostelny's camp.
Kane County Director of Elections Suzanne Fahnestock, said the recount could take at least two days as officials must count absentee, military, grace period and provisional ballots, along with early votes and votes cast March 18.
"It's a lot of information to go through," she said.
In 65 precincts in Kane County, Tegeler took home 76 more votes than Kostelny.
Kane County Clerk Jack Cunningham noted early votes for a particular precinct could have been cast anywhere in the county.
"We have to track those down," Cunningham said. "This is really a discovery (recount). A person would have to take it to court and get a court order for a full recount."
The winner will advance to the Nov. 4 election. No Democrat has filed for the seat.
