In this letter, the American Civil Liberties Union expresses its opposition to efforts to include S. 1273/H.R. 2426, the CASE Act in upcoming legislation to fund the government. The CASE Act is a controversial provision that would significantly alter the enforcement of copyright law and would have the unintended consequence of undermining free expression online. Because we recognize that it is essential to fund the federal government, particularly during the ongoing public health crisis, we ask that you decline to include the CASE Act in the upcoming funding bill and instead allow that provision to proceed through regular order where Members will have an opportunity to address the significant concerns raised by the bill before it passes into law.
