See: EU: Security Union: Commission recommends negotiating international rules for obtaining electronic evidence (European Commission press release, link):
“With the majority of criminal investigations requiring access to evidence based online and often outside the EU, there is an urgent need to equip police and judicial authorities with quick and efficient tools fit for modern reality.
Following up on the European Council Conclusions from October 2018, the Commission is presenting two negotiating mandates, one for negotiations with the United States and one on the Second Additional Protocol to the Council of Europe “Budapest” Convention on Cybercrime. Both mandates, which need to be approved by the Council, include specific safeguards on data protection, privacy and procedural rights of individuals.”
