• Adds further safeguards for U.S. signals intelligence activities, including requiring that such activities be conducted only in pursuit of defined national security objectives; take into consideration the privacy and civil liberties of all persons, regardless of nationality or country of residence; and be conducted only when necessary to advance a validated intelligence priority and only to the extent and in a manner proportionate to that priority.
• Mandates handling requirements for personal information collected through signals intelligence activities and extends the responsibilities of legal, oversight, and compliance officials to ensure that appropriate actions are taken to remediate incidents of non-compliance.  
• Requires U.S. Intelligence Community elements to update their policies and procedures to reflect the new privacy and civil liberties safeguards contained in the E.O. Creates a multi-layer mechanism for individuals from qualifying states and regional economic integration organizations, as designated pursuant to the E.O., to obtain independent and binding review and redress of claims that their personal information collected through U.S. signals intelligence was collected or handled by the United States in violation of applicable U.S. law, including the enhanced safeguards in the E.O.
• Under the first layer, the Civil Liberties Protection Officer in the Office of the Director of National Intelligence (CLPO) will conduct an initial investigation of qualifying complaints received to determine whether the E.O.’s enhanced safeguards or other applicable U.S. law were violated and, if so, to determine the appropriate remediation. The E.O. builds up the existing statutory CLPO functions by establishing that the CLPO’s decision will be binding on the Intelligence Community, subject to the second layer of review, and provides protections to ensure the independence of the CLPO’s investigations and determinations. 
• As a second layer of review, the E.O. authorizes and directs the Attorney General to establish a Data Protection Review Court (“DPRC”) to provide independent and binding review of the CLPO’s decisions, upon an application from the individual or an element of the Intelligence Community. Judges on the DPRC will be appointed from outside the U.S. Government, have relevant experience in the fields of data privacy and national security, review cases independently, and enjoy protections against removal. Decisions of the DPRC regarding whether there was a violation of applicable U.S. law and, if so, what remediation is to be implemented will be binding. To further enhance the DPRC’s review, the E.O. provides for the DPRC to select a special advocate in each case who will advocate regarding the complainant’s interest in the matter and ensure that the DPRC is well-informed of the issues and the law with regard to the matter. The Attorney General today issued accompanying regulations on the establishment of the DPRC.
• Calls on the Privacy and Civil Liberties Oversight Board to review Intelligence Community policies and procedures to ensure that they are consistent with the Executive Order and to conduct an annual review of the redress process, including to review whether the Intelligence Community has fully complied with determinations made by the CLPO and the DPRC.
