Led by Colorado Law student attorneys John Jang, Victoria Venzor, and Peter Troupe, the TLPC today filed an amicus brief with the U.S. Court of Appeals for the District of Columbia Circuit on behalf of a coalition of accessibility, security, and repair individuals and organizations, supporting the lawsuit of security researcher Dr. Matthew Green and others, represented by the Electronic Frontier Foundation, over a controversial copyright law. The brief urged the court to conclude that Section 1201 of Title 17 of the U.S. Code, added by the Digital Millennium Copyright Act of 1998, violates the First Amendment by chilling fair uses aimed at making copyrighted works accessible to people with disabilities, researching security vulnerabilities in computer software, and repairing software-enabled vehicles and devices. Section 1201 prohibits the circumvention of technological protection measures (TPMs) on copyrighted works, requiring accessibility, security, and repair organizations to pursue exemptions in a burdensome triennial rulemaking conducted by the U.S. Copyright Office of the Library of Congress. The brief details the substantive and procedural harms of Section 1201 and the rulemaking to the First Amendment rights of people with disabilities, disability services organizations and libraries, security researchers, and ordinary consumers and repair professionals.
