The US Supreme Court has heard the first evidence in the court case that will decide the legality of the Communications Decency Act (CDA).
The case, which is an appeal against a Philadelphia court's ruling that the Act is unconstitutional, will hear both sides of the argument over the next 10 to 12 days. Final deliberations will take place on 19 March.
The American Civil Liberties Union (ACLU), which has already had dealings with president Clinton in court, warned: "Because there is no way for the vast majority of Internet speakers to distinguish between adults and minors in their audience, the CDA is the most restrictive censorship scheme imposed on any medium."
