Paul M. Schwartz, a law professor at the University of California, Berkeley, said such a blanket agreement could transform international privacy law by eliminating a problem that has led to negotiations of “staggering” complexity between Europe and the United States.
“The reason it’s a big deal is that it is going to lower the whole transaction cost for the U.S. government to get information from Europe,” Mr. Schwartz said. “Most of the negotiations will already be completed. They will just be able to say, ‘Look, we provide adequate protection, so you’re required to turn it over.’”
