Wirtz v. Quinn

Taxpayers challenged three substantive bills and one appropriation bill, part of capital projects, signed by the governor in July 2009. The appellate court held that Public Act 96–34 violated the single-subject clause of the Illinois Constitution, and that the other acts were invalid because they were contingent on enactment of Public Act 96–34. The supreme court reversed, reinstating the trial court's dismissal. All of the substantive provisions in Act 96–34 are connected to capital projects; they establish revenue sources to be deposited into the Capital Projects Fund or are related to the overall subject of the Act in that they help implement other provisions. The court upheld the other acts against single-subject challenges, including challenges based on the contingency clauses. Nothing in the state constitution prohibits making legislation contingent on a separate legislative enactment. The enactments did not violate the separation of powers doctrine, public funds clause, uniformity clause, or run afoul of constitutional veto procedures. An enactment that authorizes expenditure of public funds for a public purpose is not unconstitutional for incidental benefit to private interests. There is nothing constitutionally impermissible about the inclusion of the "as approximated below" language.
