In establishing congressional and legislative district boundaries or plans, the state shall apply federal requirements and balance and implement the standards in the State Constitution. The state shall take into consideration the ability of racial and language minorities to participate in the political process and elect candidates of their choice, and communities of common interest other than political parties may be respected and promoted, both without subordination to any other provision of Article III of the State Constitution. Districts and plans are valid if the balancing and implementation of standards is rationally related to the standards contained in the State Constitution and is consistent with federal law.
