What does Executive Order 13086 do?
EO 13086 made a broad 1998 update to the Manual for Courts-Martial under Article 36 of the UCMJ. Among other changes, it prescribed 48-hour probable-cause and seven-day pretrial-confinement review, procedures for an accused who was incompetent to stand trial, government appeals involving classified information, contempt proceedings, sentence deferment and waiver of automatic forfeitures. It also revised offense explanations and maximum punishments. Later annual amendments and the Military Justice Act of 2016 substantially reorganized the Manual, so current cases must use the edition and transition rules applicable to them.

Legal and source detail
How it works legally
Article 36 permits the President to prescribe court-martial procedure, but the UCMJ and constitutional protections control. The order preserved prior proceedings and barred ex post facto punishment increases.
