But...Legislatures and courts designate regulatory agencies, through enabling acts[1] that allows said agency to exist and which lists its jurisdiction and areas of responsibility. That's how regulatory bodies exist, it's what they're for. A court established regulatory body defining what it regulates is 100% within the scope of that body under the law. So in a way, this already happens. I'm not exactly seeing the issue here. Regulatory bodies don't just appear out of nowhere, they have to be established by a legislature or a court. You're asking for a feature that already exists. [1] https://en.wikipedia.org/wiki/Enabling_act#United_States https://en.wikipedia.org/wiki/Enabling_act#United_States
