32 U.S.C. § 327 — Courts-martial of National Guard not in Federal service: convening authority

(a) In the National Guard when it's not serving under federal control, general, special, and summary courts-martial can be convened the way the laws of the relevant state, Puerto Rico, the District of Columbia, Guam, or the Virgin Islands say. (b) In that same non-federal National Guard: (1) Only the President can convene a general court-martial. (2) A special court-martial can be convened by the commanding officer of a place like a garrison, fort, post, camp, air base, or auxiliary air base where Guard members are on duty, or by the commanding officer of a division, brigade, regiment, wing, group, detached battalion, separate squadron, or similar detached command. (3) A summary court-martial can be convened by the same kind of place-based commanding officer, or by the commanding officer of a division, brigade, regiment, wing, group, detached battalion, detached squadron, detached company, or other detachment. (c) The convening authorities listed in (b) are in addition to — not instead of — the ones listed in (a).
