As from now it is available the Cybercrime Office Practical Note 14/2019 [1] regarding the new procedure to request data to Google, within a criminal investigation.
The existing Google system for receiving requests for information via e-mail is being replaced by another system, which entails submitting requests on a web portal accessed through authentication. Such authentication entails the creation of an account, via a Focal Point (currently the Cybercrime Office) that confirms the identity of the prosecutors and clerks.
