Notwithstanding any other provision of law, any organization that meets the requirements of section 170 (c) of the federal "Internal Revenue Code of 1986", as amended, may own or purchase life insurance on an insured who gives written consent to the ownership or purchase of that insurance. The provisions of this section do not limit or abridge any insurable interest or right to insure now existing at common law or by statute, shall be construed liberally to sustain the existence of an insurable interest, and shall stand as a declaration of existing law applicable to all life insurance policies whenever issued, in existence on or after March 20, 1992.
