President: Barack Obama
Revised military justice procedure, evidence and offenses, including major changes involving sexual assault cases.
Status: Superseded. Is Executive Order 13669 still in effect? No. Executive Order 13669 was superseded. See Federal Register record.
What does Executive Order 13669 do?
EO 13669 amended the Manual for Courts-Martial to reflect legislation and approved rule changes current in 2014. It addressed investigative, trial, evidentiary and punitive provisions, including reforms involving sexual offenses. Later annual executive orders and the Military Justice Act of 2016 substantially revised the system, so current cases require the latest Manual and applicable offense-date rules.
