Eric Eldred, et al. v. John D. Ashcroft, Attorney General

The Supreme Court rejects constitutional challenges, including one based on the First Amendment, to the Copyright Term Extension Act, which extended the copyright protection term by 20 years. The Court reasoned in Eldred v. Ashcroft that copyright law already has built-in First Amendment protections in the fair-use doctrine and the expression-idea dichotomy principle (providing that copyright protects expressions, not ideas).
