The move follows a court ruling in May that decided U.S. paper currency discriminates against the blind.
Treasury officials have hired a contractor to look into ways to help the blind differentiate between bills. Some ideas include printing different sizes or including raised numbers. The government has urged U.S. District Judge James Robertson not to interfere with anti-counterfeiting redesigns of money that are already in progress.
But in a ruling today, Robinson said the Treasury Department won't conduct the changes on its own schedule and terms.
He's ordered government lawyers to meet with the American Council of the Blind to come up with a schedule that requires changes in the next generation of bills.
