The EU's Article 29 Working Party, which represents data protection rules, has sent a letter (PDF) unsuccessfully trying to persuade Google to temporarily stop implementing its unified privacy policy. Under concerns that the changes may affect much of Europe, the coalition of national and continental regulators wanted a "pause" so that there wasn't any confusion over privacy rights, according to chairman Jacob Kohnstamm. The Article 29 group also said Google would need to talk to France's data regulator CNIL as its main contact for questions.
