Professor Lessig has sued Australian music label Liberation in the U.S. in relation to a computer generated take down notice sent to YouTube, to take down video of Lessig giving a seminar in Asia that included music licensed exclusively to Liberation in Australia.
If this case proceeds, there are interesting jurisdictional and fair use / fair dealing points that arise. If the use of the music was fair use in the U.S., but not fair dealing in Australia, and the video is available in Australia, one would assume that there is copyright infringement in Australia.
