In a pair of Federal Register notices available here and here, the JSC publishes its final proposed amendments to the MCM (initial proposal discussed here) and also publishes revised supplementary materials.
The proposed amendments make a number of changes that are relatively unsurprising considering recent caselaw.
The revised supplementary materials continue the positive trend (previously noted and discussed here) of the JSC independently publishing these non-binding materials. They include new Part IV discussion sections that state that bona fide suicide attempts should not be charged as criminal offenses (see United States v. Caldwell, 72 M.J. 137 (C.A.A.F. 2013) (CAAFlog case page)), and additions to the analysis of the Military Rules of Evidence that primarily identify which of the 2013 changes were merely stylistic (see my note here).
