Amends Section 1 of SL 1969-1170 to allow the Mecklenburg County Board of Commissioners (BOC) to authorize the police departments of the towns of Cornelius, Davidson, Huntersville, Matthews, Mint Hill, and Pineville, in addition to the existing authorization for the City of Charlotte police, to exercise general policing power throughout the unincorporated areas of Mecklenburg County, as designated by the Board of Commissioners. However, removes service of civil process from the grant of jurisdiction, authority, powers, and rights. Provides that officers will have the same privileges and immunities in this extended jurisdiction as in their respective municipality, as long as the municipality and Mecklenburg County enter into an agreement setting forth guidelines and procedures for implementation of this act. Provides that the BOC cannot approve this extended exercise of power and authority to unincorporated areas of the county that fall within the sphere of influence or extraterritorial jurisdiction of another municipality, unless such a municipality consents in writing. Clarifies that nothing in this section restricts or prohibits the authority already granted to the police officers of the City of Charlotte over unincorporated areas of the county as it stands on or before the date this act becomes effective. Further, clarifies that nothing in this section restricts or prohibits the Sheriff of Mecklenburg County from exercising the powers and authority of the Sheriff's Office. Makes conforming and clarifying changes.
