The Nebraska Governmental Unit Credit Facility Act shall be independent of and in addition to any other provision of law of the State of Nebraska or provisions of home rule charters, and any credit facility may be obtained under the act for any purpose authorized in the act even though other laws of the State of Nebraska or provisions of home rule charters may provide for the obtaining of a credit facility for the same or similar purposes. The act shall not be considered amendatory of or limited by any other law of the State of Nebraska or provisions of home rule charters, and any credit facility may be obtained under the act without complying with the restrictions or requirements of any other law of the State of Nebraska, except when specifically required by the act, or without complying with the restrictions or requirements of home rule charters. Nothing in the act shall prohibit or limit the obtaining of any credit facility in accordance with other applicable laws of the State of Nebraska or of home rule charters, if the governing body of a governmental unit determines to obtain such credit facility under such other laws or charter or otherwise limit the provisions of any home rule charter.
