Section 810 ILCS 5/9-709 - Priority(a) Law governing priority. This Act determines the priority of conflicting claims to collateral. However, if the relative priorities of the claims were established before the effective date of this amendatory Act of the 91st General Assembly, Article 9 as it existed before the effective date of this amendatory Act of the 91st General Assembly determines priority.(b) Priority if security interest becomes enforceable under Section 9-203. For purposes of Section 9-322(a), the priority of a security interest that becomes enforceable under Section 9-203 of this Act dates from the effective date of this amendatory Act of the 91st General Assembly if the security interest is perfected under this Act by the filing of a financing statement before the effective date of this amendatory Act of the 91st General Assembly which would not have been effective to perfect the security interest under Article 9 as it existed before the effective date of this amendatory Act of the 91st General Assembly. This subsection does not apply to conflicting security interests each of which is perfected by the filing of such a financing statement. P.A. 91-893, eff. 7/1/2001.
