Besides suggesting the controversial move of making law enforcement responsible for investigating and prosecuting intellectual property infringement, the proposal has come under fire for the exclusive group of countries included in the initial discussions. Unlike the World Intellectual Property Organization (WIPO) or World Trade Organization (WTO), every member of the G8 have businesses that derive a significant amount of revenue from intellectual property.
Although representatives of non-G8 countries will be in attendance at the summit, with the secrecy surrounding the entire issue of the ACTA treaty there's no way to know whether any of them will be consulted or even briefed on any relevant discussions. In fact the description on the event's official website is merely a mention that "protection of intellectual property rights" will be "discussed."
