On Wednesday, Nov. 28, the US Supreme Court heard oral arguments in a major test of free speech online. In the case of Ashcroft v. ACLU, the court is considering the constitutionality of the 1998 Child Online Protection Act (COPA). COPA imposes criminal and civil sanctions on any person who uses the Web to display "any material that is harmful to minors" to anyone under the age of 17. Two federal courts have prohibited enforcement of COPA because it violates the First Amendment. CDT filed briefs in the case, which could test the Court's landmark 1997 Internet free speech ruling in Reno v. ACLU.
