Who wrote and enacted the Uniform Code of Military Justice?

The Uniform Code of Military Justice (UCMJ) was written and enacted by the United States Congress. This significant piece of legislation provides the legal framework for the military justice system and applies to all members of the Armed Forces. The UCMJ was originally enacted in 1950 as part of the National Defense Authorization Act. It establishes the rules, procedures, and penalties for military personnel, ensuring that service members are held accountable for their actions under a consistent set of laws. Congress has the authority to create and amend federal laws, and the UCMJ is an example of its role in establishing legal standards that govern military conduct. The other options, such as state legislatures, the Department of Defense, and the Supreme Court, do not have the legislative power to enact military codes of justice, making them incorrect choices in this context.
