A. Notwithstanding the provisions of any other law or of any charter or any ordinance, any school board may, by resolution, authorize the acquisition and purchase from the United States or any agency thereof of any equipment, supplies, materials, or other property, real or personal, in such manner as such school board may determine.
B. It is the purpose of this section to enable school boards to secure from time to time promptly the benefits of acquisitions and purchases as authorized by this section, to aid them in securing advantageous purchases, to prevent unemployment and thereby to assist in promotion of public welfare and to these ends school boards shall have power to do all things necessary or convenient to carry out such purpose, in addition to the expressed power conferred by this section. This section is remedial in nature and the powers hereby granted shall be liberally construed.
