Who had to do what
| Agency / office | Action | Timing / position |
|---|---|---|
| Military prosecution | Apply the revised burdens of proof: ordinarily disprove defenses beyond a reasonable doubt, and do so for the specified mistake-of-fact defenses after the accused establishes the initial defense by a preponderance of evidence. | Amendments effective October 1, 2007, subject to the order’s protection of earlier conduct and proceedings. |
| Military judge | Apply the revised instructions on proof and defenses; may convene post-trial Article 39(a) sessions to resolve matters or reconsider rulings affecting legal sufficiency. Before entering an acquittal on the judge’s own initiative, give both parties an opportunity to be heard; pre-authentication acquittals follow the specified limits. For covered sexual-history evidence, conduct a closed admissibility hearing, allow the alleged victim to attend and be heard, seal the materials, and specify any permitted evidence and examination. | Post-trial acquittal power before record authentication; evidence hearing before admitting the covered evidence. |
| Party offering sexual-history evidence | File a written motion describing the evidence and its purpose, serve it on the other party and military judge, and notify the alleged victim or appropriate guardian or representative. | At least 5 days before entry of pleas unless the judge sets another time for good cause or permits filing during trial. |
| Judge Advocate General | Transmit the trial record, criminal-appeals and Armed Forces appeals decisions, and the Judge Advocate General’s recommendation to the Secretary concerned when the affirmed sentence requires presidential approval. | After the Court of Appeals for the Armed Forces affirms a sentence requiring presidential approval before execution. |
| Secretary of the military department concerned | Forward the received record, decisions, and Judge Advocate General’s recommendation to the Secretary of Defense with the department Secretary’s recommendation. | When receiving the materials for a sentence requiring presidential approval. |
| Secretary of Defense | Forward the materials and both Secretaries’ recommendations to the President for presidential action. | Following receipt from the military department Secretary; before execution of the sentence requiring approval. |
| Secretary of Homeland Security | Forward the materials received from the Judge Advocate General directly to the President with the Secretary’s recommendation. | When Homeland Security is the Secretary concerned; before execution of the sentence requiring approval. |
| Courts-martial | Apply the revised offense definitions, elements, evidentiary rules, defenses, and maximum punishments, including the revised sexual-offense and child-endangerment provisions. | From October 1, 2007; earlier nonpunishable conduct cannot become punishable, and proceedings begun earlier remain protected by the savings clause. |
