lower jurisdictions can challenge the necessity or scope of higher jurisdictions. each jurisdiction must be tightly tailored to the needs of a distinct and particular separation. that distinction must be of the most relevant kind, not merely one or some combination of lesser distinctions unless those distinctions are tightly bound or inseparable and significant enough to outweigh a more distinct, larger need.
ex: world government, continental government, geographic area government (based on climate and other geographic issues), breaking down into smaller types of distinctions - previous national culture/language based government, long-registered city-ships government, well-recognized district government, etc.
intent: that each jurisdiction is in charge of the largest issues which concern it and leave all details to lesser jurisdictions except how and where they affect the larger whole.
