Tillman v. Pritzker

Summary

The court held that the statutory reasonable-ground inquiry for a taxpayer action permits the circuit court to consider both the legal sufficiency of the proposed complaint and affirmative defenses. Because the taxpayer waited sixteen years to challenge the 2003 bonds and two years to challenge the 2017 bonds, and the State was prejudiced by the delay, laches barred the proposed action. The court therefore reversed the appellate court and affirmed the circuit court's denial of leave to file.
