Each senate district created by this title shall be deemed a separate district for the purpose of apportionment of the entire state into senate districts. If one or more senate districts created by this title are judicially found to be invalid or unenforceable for any reason, including but not limited to non-compliance with decisions and mandates of a court of competent jurisdiction, only the defective district or districts and those immediately adjacent or contiguous thereto shall be reapportioned. All other districts shall be deemed to be properly created.
