SACRAMENTO, Calif. (AP) – Opponents of an initiative to split California into three states are asking the state Supreme Court to pull the measure from the ballot. The lawsuit filed Monday on behalf of an environmental group argues the measure exceeds the scope of an initiative because it would drastically alter California’s government and constitutional framework. The California Supreme Court has struck down ballot measures in the past after ruling they went too far in changing government structure. The initiative would break the state into Northern California, California and Southern California. Supporters of splitting California argue the nation’s most populous state has become ungovernable because of its size, wealth disparities and geographic diversity. Draper and a spokeswoman for the initiative did not comment on the lawsuit.
