plaintiff:
  - HKSAR

defendant:
  - CHAN NAI MING

case_reason: Criminal prosecution for distribution of infringing copies of copyright works using BitTorrent file-sharing system, contrary to section 118(1)(f) of the Copyright Ordinance, Cap. 528. The defendant seeded three films on the Internet without commercial purpose but to an extent prejudicial to copyright owners.

judgment_summary: This landmark case represents the first prosecution in Hong Kong (and possibly worldwide) for copyright infringement using BitTorrent technology. The defendant uploaded three films to the Internet using BitTorrent, creating .torrent files and publishing them on a newsgroup accessible to anyone. He acted as the original seeder, maintaining his Internet connection to enable 35-40 users to download each film. The Magistrate emphasized that Hong Kong's firm deterrent sentencing policy for copyright infringement applies equally to non-commercial distribution via the Internet. Despite the absence of commercial gain, the court found the potential harm to copyright owners substantial due to the insidious nature of Internet distribution and the risk of re-distribution. The defendant was sentenced to three months' imprisonment (concurrent on three charges), with a warning that future offenders may face longer terms comparable to commercial piracy cases.
