And here's an up-to-date copy of the MCM issued and enforced by the CiC/President. The JSC can make recommendations, but it is up the to President to use an EO to make changes and to see that they are enforced all teh way down the chain.
All authority trickles down from the CiC. Without which, there IS no military command structure that has any force of legality what-so-ever. Deliberately made that way by the Founders to keep the military power subordinate to the civil power.
If there is a question about the CiC's eligibility to enforce the UCMJ and the MCM, then damn straight any courts martial proceedings taking place are called into question.
The UCMJ is a federal law and the basis of our military justice system. It determines what conduct is criminal, establishes the various types of courts, and sets forth the procedures to be followed in the administration of military justice. You can find the UCMJ in Appendix 2 of the MCM, United States, 1984 or in 10 United States Code (USC) §§801-940.
The MCM is an executive order that details the rules for administering military justice. For example, it sets forth the rules of evidence for courts-martial and contains a list of maximum punishments for each offense.
The civil power to which the military power is subordinate per the Constitution is both Legislative and Executive. That means Congress and the President. It's right there in the Constitution.
Honest. Read it. Judge Lind did. She even cited it. So, darn straight, you don't know what you're talking about.
And why do you think the MCM is a clever test? I was in the army.
