Censorship of the Internet is open to challenge at the World Trade Organization as it can restrict trade in services delivered online, a forthcoming study says. A censorship case at the WTO could raise sovereignty issues, given the clear right of member states to restrict trade on moral grounds -- for example, by blocking access to child pornography websites. But a WTO ruling could set limits on blanket censorship and compel states instead to use more selective filtering, according to the study, to be published on Thursday by think-tank ECIPE. "Censorship is the most important non-tariff barrier to the provision of online services, and a case might clarify the circumstances in which different forms of censorship are WTO-consistent," said the study by Brian Hindley and Hosuk Lee-Makiyama.
