I want to know the answer to the following question:
Which organization filed an accessibility lawsuit?
All the background I'm provided with is that "As a result of a 2008 decision in an accessibility lawsuit filed by the American Council of the Blind, the Bureau of Engraving and Printing is planning to implement a raised tactile feature in the next redesign of each note, except the $1 and the version of the $100 bill already in process.". Is that enough to answer the question?
Answer: yes
