A COS can also decide to do ANYTHING else it wants - all with zero oversight or limits by ANY agency, legislative edict, or even courts - up to an including throwing out the US Constitution and substituting a brand new document in its place (much like happened with the First such calling of a Convention that transitioned the US from the Articles of Confederation to the Constitution.
It is quite literally impossible to put any sort of restraint or limits to a COS -
As much as I would absolutely LOVE having term limits for Congress (and a few other protections) enshrined in the Constitution - the danger is a very real problem that many seem to either be ignorant of - or just don’t care.
Under a COS - you can bet the farm that the 2nd Amendment will be one of the first things assaulted (assuming the COS delegates - led by the vast number of delegates of the most liberal states don’t just trash the whole Constitution to begin with).
Delegates to a COS are limited by their commissions.
