Delay in notification is acceptable where notification would frustrate the purpose of communication surveillance and authorization is granted by a competent judicial authority. Transparency Information about use and amount of Communication Surveillance should be available to those who request it. States should provide the requestor with information sufficient to ascertain the nature of the request and determine the size of both the request and those who will be affected by it. Records of requests for communications surveyed should also be published. Public Oversight States should establish an independent position to oversee the use of Communications Surveillance and to ensure transparency and accountability. The person(s) in this position would have sufficient authority to access all potentially relevant information, to assess whether the State is making legitimate use of its lawful capabilities, to evaluate whether the State has met its transparency obligations, and to make public determinations as to the lawfulness of those actions.

Integrity of communication and systems States should not require those service providers or software/hardware vendors to build surveillance/monitoring capability into their systems. People have a right to express themselves anonymously. Safeguards for International Cooperation Where a state has entered into a mutual legal assistance treaty(MLAT) or other multi-jurisdictional agreement where more than one legal jurisdiction overlaps, the laws that apply are those which have the higher level of protection for the individual. MLAT's should also be transparent, publicly available and subject to guarantees of procedural fairness Safeguards against illegitimate access and right to effective remedy Communications surveillance by third parties should be prohibited with sufficient penalties. Protection for whistle-blowers should be enacted. Any information obtained by means not consistent with these principles should be inadmissible as evidence. Once information collected by communications surveillance has been used for the purpose for which it was collected it should be promptly destroyed or returned. Response In October 2013, The Principles were promoted in a brief filed before the President's Review Group on Intelligence and Communications Technologies. They claim that "In a world of ever more complex technology, it is increasingly unclear whether the distinction between "meta-data" and other information carries much weight." The Center for Democracy and Technology released a report noting overlap between the Principles and a December 9, 2013 proposal by tech groups such as
