As mentioned last week, the Federal Court issued an order allowing Voltage Pictures to obtain information from ISPs about subscribers who had allegedly downloaded the “Hurt Locker” movie (Voltage Pictures LLC c. Mr. or Ms. DOE, 2011 CF 1024 – Translation). A copy of the supporting affidavit (PDF) providing the plaintiff’s facts linking the downloading of the movie to IP addresses is now available online (thanks @AnthonyHemond).
In BMG Canada v. Doe, 2005 FCA 193, one of the leading cases in this area of the law, the recording companies brought a motion for documents in the possession of the ISPs under Federal Courts Rules, Rule 233. The court ultimately denied the motion in that case and concluded that the supporting evidence connecting the pseudonyms of the P2P users with IP addresses was inadequate. At the time, the Federal Court of Appeal wrote:
 Much of the crucial evidence submitted by the appellants was hearsay and no grounds are provided for accepting that hearsay evidence. In particular, the evidence purporting to connect the pseudonyms with the IP addresses was hearsay thus creating the risk that innocent persons might have their privacy invaded and also be named as defendants where it is not warranted. Without this evidence there is no basis upon which the motion can be granted and for this reason alone the appeal should be dismissed.
From the Federal Court’s ruling in the Voltage proceeding, this does not appear to have been an issue.
