This is not just a plug, but based on your question, we have released just this week, with our international partners, a report on information sharing and surveillance. The CCLA has included a chapter in that report on the Re (X) case. The other partners who have written include information sharing laws in the United States, Russia, Kenya, South Africa, and India. We'd be happy to make that report available to you.
On November 3rd, 2016. See this statement in context.
