"The court found that Bredbandsbolaget's operations do not amount to participation in the copyright infringement offences carried out by some of its 'pirate' subscribers.
The action was brought by Universal Music, Sony Music, Warner Music, Nordisk Film and the Swedish Film Industry, who teamed up in a lawsuit last year designed to force Bredbandsbolaget to block the site. They claimed that, unless it blocks Pirate Bay, Bredbandsbolaget should be held responsible for the copyright infringements of its customers".
