"The U.S.Constitution has long prohibited the use of debtors' prisons to incarcerate defendants who cannot afford to pay fines and court costs," Christine Link, executive director of the ACLU of Ohio wrote to O'Brien.
"It is our sincere hope that we can avoid instituting litigation over these issues," Link wrote, asking O'Brien to stop the practice and establish a written policy detailing compliance with the law. She also asked O'Brien to "remove from the total amounts owed by defendants any costs and fees charged to them as a result of warrants based on failure to pay fines and costs."
The letter was copied to Ohio Supreme Court chief Justice Maureen O'Connor.
