EMI subsidiary Capitol Records’ lawsuit against digital music reseller ReDigi has reached court, with the opening arguments for both sides crystallising the debate around the disruptive service. “You are selling and distributing recordings. In order to do that, you have to make a copy and that is a violation of the reproduction right of the Copyright Act,” said Capitol’s lawyer Richard Mandel. “There is no copy involved. The actual file is being transported. That’s how the technology works,” replied ReDigi’s Gary Adelman. Whichever way the ultimate verdict swings, it will have implications well beyond ReDigi.
