Aug 2, 2023

Summary

Changes the official rulebook for military courts to include new laws and procedures, ensuring the justice system is up to date.

What problem does this solve?

The rules for military courts, known as the Manual for Courts-Martial, were outdated and did not include recent changes made by law. This order updates the manual to match the new laws, making sure all military legal actions follow the correct, current rules.

What does this order do?

Immediate changes to the manual
Updates several parts of the Manual for Courts-Martial (Parts II, III, IV, and V) as detailed in Annex 1. These changes are effective immediately as of the order's date.
New appendices and changes effective late 2023
Adds three new appendices (12B, 12C, 12D) and changes Part II of the manual. These updates, detailed in Annex 3, become effective on December 27, 2023.
Future changes based on NDAA FY 2022
Updates most parts of the Manual for Courts-Martial (Parts I-V and Appendix 12A) based on Annex 2. These changes will take effect on a date set by the 2022 National Defense Authorization Act.
Protection from retroactive punishment
Ensures that none of the new rules can be used to punish someone for an act that was not illegal at the time it was committed.
Ongoing cases are not affected
States that any legal proceedings, such as a trial or hearing, that have already started will not be invalidated by these new rules and can continue as they were.

Who does this affect?

  • U.S. Armed Forces members
  • Military legal personnel

What is the real world impact?

Keeps military law current
Updates the Manual for Courts-Martial to align with new laws passed by Congress, specifically the National Defense Authorization Act for Fiscal Year 2022. This ensures the military's legal system operates under the most current federal law.

Annex 1 amendments
The changes described in Annex 1 take effect on July 28, 2023.
Annex 3 additions and amendments
