MARION, Ind. — A judge says he will no longer conduct Superior Court and Juvenile Court operations at the Grant County Courthouse because of a mold problem that is aggravating his health problems.

Judge Randall Johnson said in a letter to county officials that repairs need to be made to the courthouse to address the mold problem. He said doctors have found high levels of several molds in his blood, and that many were the same kind found in the courthouse during a Department of Labor study in March.

The county council voted last week to accept a 60-month line of credit from a bank to pay for $1.8 million in repairs. Johnson said the process has been long and frustrating.

“It’ll be four more months before we get started on anything,” he said.

Johnson said Superior Court 2 and Juvenile Court need to be moved until repairs are complete.

County Administrator Angela Banter said Juvenile Court will move to the county council chambers. Cases will be heard there beginning Monday, she said.

Officials are still looking for a new venue for Superior Court, which requires special technology, recording equipment, security and a separate jury room. Banter said she is compiling information on locations and will present it to county commissioners Tuesday.

Circuit Court Judge Mark Spitzer said Johnson’s decision likely will not have a major affect on other courts. Spitzer plans to keep his courtroom open.

“I don’t have any plans to close my court, but that doesn’t mean I’m not concerned about the health of my staff and the public,” Spitzer said.

The courthouse roof was damaged and was not repaired, allowing water to seep in and cause mold, Johnson said. He said that courthouse employees have reported health problems including headaches, sinus problems, breathing problems, nose bleeds and dizziness.
