Litigation
The Institute defends the freedoms of speech and of the press through strategic litigation designed to have a meaningful impact on the law, on public policy, and on public opinion. We litigate cases that have the potential to establish important new legal principles concerning the system of free expression, to influence the practices of powerful actors in that system, and to raise public awareness about contemporary structural threats to that system. We focus especially on complex and challenging cases that relate to new technology, including new communications platforms, and we favor cases that afford us the opportunity to draw on insights generated by our research program.
Our litigation prioritizes cases in our three focus areas, Free Speech & Social Media, Transparency & Democracy, and Privacy & Surveillance.
