625 ILCS 5/20-401
The repeal of any Act by this Chapter shall not affect any right accrued or liability incurred under said repealed Act to the effective date hereof.
The provisions of this Act, insofar as they are the same or substantially the same as those of any prior Act, shall be construed as a continuation of said prior Act. Any license, permit, certificate, registration, registration plate or digital registration plate, registration sticker or digital registration sticker, bond, policy of insurance or other instrument or document issued or filed or any deposit made under any such prior Act and still in effect on the effective date of this Act shall, except as otherwise specifically provided in this Act, be deemed the equivalent of a license, permit, certificate, registration, registration plate or digital registration plate, registration sticker or digital registration sticker, bond, policy of insurance, or other instrument or document issued or filed or any deposit made under this Act, and shall continue in effect until its expiration or until suspended, revoked, cancelled or forfeited under this Act.
Furthermore, when any section of any of the various laws or acts repealed by this Act is amended by an Amendatory Act of the 76th General Assembly, and such amended section becomes law prior to the effective date of this Act, then it is the intent of the General Assembly that the corresponding section of this Code and Act be construed so as to give effect to such amendment as if it were made a part of this Code. Should, however, any such Amendatory Act amend a definition of a word or phrase in an act repealed by this Act, and such becomes law prior to the effective date of this Act, it is the further intent of the General Assembly that the corresponding section of this Code specifically defining such word or phrase be construed so as to give effect to such amendment, and if not specifically defined, that the corresponding section of Chapter 1 of this Code be construed so as to give effect to such amendment. In the event that a new section is added to an act repealed by this Act by an Act of the 76th General Assembly, it is the further intent of the General Assembly that this Code be construed as if such were made a part of this Code.
