U.S. paper money discriminates against the blind and must be redesigned to help sight-impaired people distinguish among dollar bills, tens, twenties and other amounts, a federal appeals court ruled.

The U.S. Court of Appeals for the District of Columbia Circuit, in a 2-1 ruling today, rejected Treasury Secretary Henry Paulson’s contention that changing the bills to differentiate the denominations would be too expensive.

“A large majority of other currency systems have accommodated the visually impaired, and the secretary does not explain why U.S. currency should be any different,” Judge Judith Rogers wrote for the majority. “The financial costs identified by the secretary are not out of line with the costs of other currency changes the secretary has made”, she said.

U.S. District Judge James Robertson in Washington ruled in 2006 that the same-size paper currency violates the Rehabilitation Act of 1973, which prohibits discrimination based on disability. An inability to identify the value of paper money without help from others leaves blind and sight-impaired people at risk of being cheated, he said.

Of 180 countries that issue paper money, only the U.S. prints bills that are identical in size and, until recently, color for all denominations.
