CDT has joined Public Citizen and other groups on a "friend of the court" brief urging a U.S. Appeals Court to correct a point in a recent decision regarding "Section 230," a provision which enhances free speech online by protecting service providers from liability for content posted by their users. Section 230 is vital because without it, private sites such as Yahoo! or Youtube could not risk allowing Internet users to freely post content. In its recent decision in Barnes v. Yahoo!, the court incorrectly limited the ability of service providers to assert the protection of Section 230. The brief supports Yahoo’s request to remove the incorrect section of the decision.
