Constitutional oligarchy proposals

Some proposals for a Cascadian government would take the form of a constitutional oligarchy, where lieutenants of several sovereigns would exercise foundational and reserve powers for the Cascadian government. A constitutional oligarchy would probably entail recognition of the British monarchy in addition to other foundations of sovereignty in the Cascadian system. Lieutenants could be appointed, like the Canadian Governor General; elected, in the case of a popular sovereign; or technocratic.
