I think there are, happily, voices being raised that are counter to Professor Geist's. There are lots of arguments on the other side, as you can read in other blogs by people such as Hugh Stephens and Barry Sookman.
That said, there is an enormous amount of due process built into the application. The organization that would be set up is to be set up thus because it is an expedient way, with experts, to deal with the triage of the applications that would come in. There would be transparency and there would be a public proceeding in that process, but ultimately the Internet piracy review agency would make a recommendation to the CRTC, and the CRTC itself would make the decision as to whether a website should be put on the blocked list and therefore be required to be blocked by the ISPs.
The alleged pirate would have the full panoply of remedies available to him, if he or she disagreed with the determination of the commission: they could ask for a “review and vary” or they could appeal the decision to the Federal Court of Appeal, just as in any other case that comes before the CRTC.
