(ILCS Ch. 5, Act 70, § 3)
(B) No new law shall be construed to repeal a former law, whether such former law is expressly repealed or not, as to any offense committed against the former law, any act done or penalty, forfeiture, or punishment incurred, any right accrued, or claim arising under the former law, or in any way whatever to affect any such offense or act so committed or done, or any penalty, forfeiture or punishment so incurred, or any right accrued, or claim arising before the new law takes effect, except only that the proceedings shall, as far as practicable, conform to the law in force at the time of the proceeding. If any penalty, forfeiture or punishment be mitigated by any provisions of a new law, such provision may, by the consent of the party affected, be applied to any judgement pronounced after the new law takes effect. This section shall extend to all repeals, either by express words or by implication, whether the repeal is in the act making any new provision upon the same subject or in any other act.
