Johnson's candidacy was challenged by Matt Metcalf of Roswell, who filed a complaint with the Georgia Secretary of State's Office saying Johnson owed more than $15,000 in state and federal taxes.
According to the Georgia Department of Revenue, Johnson owes $3,638 in taxes. The IRS says he owes $11,447 in taxes.
Johnson admitted that he defaulted on both his state and federal taxes, but said he has entered into a payment plan with the IRS and an installment plan with the state to remedy his liabilities, Malihi said in his order.
The problem, however, is that Johnson failed to take care of the problems before he formally filed his notice of candidacy with the state, Malihi said.
"Accordingly, he did not meet the qualification for office at the time he swore that he was eligible to hold office," Malihi wrote. "... Therefore, he does not meet the constitutional qualifications and is ineligible to be a candidate for Superior Court judge."
