The National Conference of the Commissioners on Uniform State Laws (NCCUSL) is a legislature in every way but one. It drafts uniform acts, debates them, passes them, and promulgates them, but that passage and promulgation do not make these uniform acts law over any citizen of any state. These acts become the law of the various states only ex proprio vigore - only if their own vitality influences the legislators of the various states to pass them.
