Instead of Keyzer, a lawyer who works for the IFPI testified to downloading infringing content using a Pirate Bay tracker. But when questioned by the defense he admitted to using a feature of BitTorrent that would allow him to download with no tracker whatsoever.
Referring to screenshots he took as evidence, he acknowledged that he assumed The Pirate Bay was used because the address of a tracker he found there was shown on the screen.
