1. Article 9(1) of the TRIPS Agreement in conjunction with Article 11(1)(ii) of the Berne Convention (1971) requires that authors enjoy the exclusive right of authorizing "any communication to the public of the performance of their works". Section 3(1)(f) of the Copyright Act grants to authors the sole right "in the case of any literary, dramatic, musical or artistic work, to communicate the work to the public by telecommunication". The term "telecommunication" in the Copyright Act is limited to transmissions "by wire, radio, visual, optical or other electromagnetic system". Why does the Copyright Act limit communications to those "by telecommunication"?
