Executive Order 12888: 1993 Amendments to the Manual for Courts-Martial, United States, 1984
President: Bill Clinton
Revised military-justice procedure, evidence and offense explanations in the 1984 Manual for Courts-Martial; later editions and executive orders superseded the operative text.
Status: In effect. Is Executive Order 12888 still in effect? Yes. Executive Order 12888 remains in effect. See Federal Register record.
What does Executive Order 12888 do?
EO 12888 amended the 1984 Manual for Courts-Martial across pretrial confinement, judicial discipline, immunity, pleas, findings, classified information, impeachment evidence and controlled-substance offenses. It supplied notice and hearing protections for professional discipline and revised several evidentiary standards. These changes became part of the evolving Manual, but current courts-martial use the current Manual and later amendments, not the 1993 text alone.

Legal and source detail
How it works legally
Article 36 of the UCMJ authorizes presidential procedural rules, but constitutional and statutory law control. Later Manuals and executive orders supersede inconsistent 1993 text, and the order preserved prior proceedings where its transition clauses applied.
