Notwithstanding any other Act to the contrary, each State agency that is subject to contingency reserves under Section 1-10 is authorized to promulgate emergency rules pursuant to subsection (n) of Section 5-45 of the Illinois Administrative Procedure Act to limit, reduce, or adjust services, payment rates, expenditures, transfers of funds, and eligibility criteria as necessary to implement the fiscal year 2010 budget and any contingency reserves designated by the Governor, to the extent permitted by federal law. Any such adjustment, reduction, or limitation shall expire on July 1, 2010. Nothing in this Section shall require rulemaking if the limitation, reduction, or adjustment would otherwise be within the authority of the agency without rulemaking.
