Swiss Justice Minister Decides That ISPs Should Have To Retain Data Despite No Legal Basis

Thanks for the clarification. I don't understand the exact meaning of "ordinance" in this context. Is this a law that was preceded by a parliamentary vote or just some kind of regulation? (this can make a big difference when determining whether this is compatible with the European Convention on Human Rights)

Surely "all data" cannot be logged, so I assume that you are talking about traffic data. It would be interesting to see this aspect being compared to the EU data retention directive.
