Sexual Assault Training Oversight and Prevention Act or STOP Act - Establishes a Sexual Assault Oversight and Response Council, composed mainly of civilians, as an independent entity from the chain of command of the Department of Defense (DOD).
Directs the Council to: (1) appoint personnel to the Sexual Assault Oversight and Response Office, and advise such Office; (2) appoint the Director of Military Prosecutions (Director); (3) review each request of the Director with respect to a case stemming from a sexual-related offense that has been referred to a military appellate court or to the Department of Justice (DOJ); and (4) submit to the Secretary of Defense, Congress, and the Attorney General a report on each Director request for referral to a higher court. Requires the Council to advise on the development of sexual assault reporting protocols, risk-reduction and response training, and policy.
Establishes within DOD the Sexual Assault Oversight and Response Office, headed by an Executive Director, to undertake specified duties and responsibilities relating to the investigation, prevention, and reduction of sexual assault incidents within the Armed Forces. Requires the Office to establish protocols to ensure that all reports of sexual assault are taken out of the chain of command and reported directly to the Office.
Establishes the position of Director of Military Prosecutions, appointed by the Council, to have independent and final authority to oversee the prosecution of all sexual-related offenses committed by a member of the Armed Forces, and to refer such cases to trial by courts-martial.
Amends the Duncan Hunter National Defense Authorization Act for Fiscal Year 2009 to require the Secretary to implement a centralized database, known as the Military Sexual Registry, for the collection of information regarding sexual assaults within the military, including the nature of the assault, the victim, the offender, and the outcome of associated legal proceedings. Requires the Registry to be housed and maintained within the Office.
