everything but the girl

Both courts also found that the standards for material that had to be hidden from open browsing were so loosely defined that any content not suitable for a four-year-old would have been hidden behind a age-verification firewall.

"Unlike COPA, filters permit adults to determine if and when they want to use them and do not subject speakers to criminal or civil penalties," the court wrote.

The Justice Department has been defending COPA since its passage in 1998, when the ACLU and others filed suit against the censorship law and won an immediate injunction. Since then, the court battle has made its way twice to the Supreme Court, though the government has never won any clear battles in the dispute.

COPA makes it a crime to knowingly post material that is "harmful to minors" on the web for "commercial purposes" without having some method -- such as a credit card -- to verify a visitor's age.

Critics assailed the law for infantilizing the internet and requiring website operators -- including news sites -- to live in fear of prosecution if even a small part of their website contained adult material.
