The accused sought disclosure of operational copies of BitTorrent investigative software, related manuals, source code, and associated materials used in a child pornography investigation.
The court held that operational copies of the software were relevant to anticipated Charter and Garofoli applications and to an issue at trial, but nevertheless refused production after balancing the accused’s interests against the public interest in preserving investigative technique privilege.
The court found that certain narrow categories of private information, including peer identification data and methods by which the software identified itself on the network, were not relevant and were privileged.
Most Crown redactions to manuals, logs, transcripts, and validation materials were upheld, although some were ordered removed where the information was relevant and non-privileged.
