1. What was the basis for Gonzalez’s appeal?
2. How did the U.S. Court of Appeals for the Seventh Circuit respond to Gonzalez’s claim?

Easterbrook, Circuit Judge.
Last June the Supreme Court held in MGM Studios, Inc. v. Grokster, Ltd. .

The foundation of this holding is a belief that people who post or download music files are primary infringers.
