I’m not sure the rumored/leaked “Anti-Counterfeiting Trade Agreement” (14MB pdf) is really a trade agreement. The provisions receiving attention make it sound much more like an intellectual property enforcement cooperation agreement. David Post says “it is really about is the tighter enforcement of copyright law on the Net.” Margot Kaminski says it “amps up IP protection and criminal sanctions, without respecting existing international institutional process and involving the interests of developing countries.”
I know nothing about ACTA. If posts from Volokh to Balkinization say it’s bad law, there’s a decent chance it is. I haven’t seen any trade bloggers analyzing the proposed deal.
