Tunk: It will prove interesting if a clever person is the first taken to the tribunal if this becomes law, depending on what service they are accused of downloading on.
For example bittorrent will require a large portion to be downloaded from the accused, IP alone will be ripped apart by anyone who knows anything about trackers (fake IPs from trackers or inserted by 3rd party is common).
I definitely agree with fines for false or baseless accusation/insufficient evidence, as I have received a couple of them myself and had the notices removed from my account which would be easy to look up in ISP logs.
Would be interesting, however I think the clever ones will be using VPN's or Seedboxes.
I'm going to be watching this new course of action with alot of interest.
