Since then, the legal team made some amendments to the RIPE 675 document that I had referenced during my talk.
The amendments were presented to the board, which approved them through Resolution EB#179-R-05.
You can read more about this in the board meeting minutes under 9.5 "Update to sharing information with LEAs"
As for your question about discussing the principles on the mailing list, we are still awaiting a legal impact analysis on e-evidence, which is scheduled for later this year. Once we have that we will be in a better position to have a more informed discussion with the community about the principles they would like to see.
In the meantime, we have worked on some guidelines for Law Enforcement Agencies and Competent Authorities, which is planned to be published on our website ahead of the RIPE meeting.
Cheers and hope to see you all at RIPE 90
