You may remember that soon after the entertainment industry provided The Pirate Bay with a ton of free publicity by getting the site (oh so briefly) shut down, its next target was isoHunt, which similarly backfired
. While isoHunt is still involved in litigation in the US with the MPAA, up in Canada, the Canadian Recording Industry Association (CRIA) has sent it a threatening letter demanding that it shut down. Similar threats have worked against other BitTorrent tracker sites, but isoHunt feels that it's on pretty firm legal grounds, and has filed a lawsuit against the CRIA, asking for a declaratory judgment that its service doesn't infringe on copyrights
. It's using a similar explanation as its US lawsuit, noting that it's no different
than a search engine. It also points out that when given evidence of infringing content, it takes down the related trackers -- which again should help put the site on pretty strong legal ground. While Canadian copyright law is different than US law, this is an important case to watch.
