The Supreme Court of Canada has agreed to look at the question of copyright on material downloaded from the Internet.
The justices have granted leave to appeal in a case involving music in video game downloads and another brought by the major Internet service providers.
They both stem from a 2007 Copyright Board decision setting royalty scales for downloads.
The Federal Court of Appeal refused last fall to review the board's decision and the video game industry and the big service providers went to the Supreme Court.
Their cases will be heard alongside a third case pitting composers, authors and music publishers against the big Internet companies over payments for downloading previews.
The court also says it will hear a fourth Internet case in which actors, producers and writers seek to overturn a Federal Court of Appeal definition of broadcasting.
The appeal court ruled that Internet service providers aren't in the broadcasting business when they provide access to TV programs, movies and made-for-Web material.
As usual, the justices gave no reasons for their decisions.
The three cases being heard together all involve copyright and, by extension, who gets what from revenues from Internet downloading.
In the "broadcasting" case, the creative groups want the big ISPs to come under the Broadcasting Act because they would then have to contribute to programming.
