What procedure must be followed to challenge legislative actions in Illinois?

To challenge legislative actions in Illinois, the proper procedure is to file a suit in an appropriate court for judicial review. This process allows individuals or entities to question the legality or constitutionality of legislation in a judicial setting. The courts then examine the legislative action to determine if it complies with the Illinois Constitution and relevant laws.

Judicial review is a fundamental aspect of the checks and balances within the government, ensuring that no branch exceeds its authority. By bringing the issue before the courts, plaintiffs can seek a definitive ruling on whether the legislation in question aligns with constitutional provisions, which ultimately safeguards citizens' rights and maintains the rule of law.

The other options do not serve as appropriate procedures for this purpose. A direct appeal to the Governor does not provide a mechanism for legal review, while a referendum vote is a process for the public to decide on specific laws or amendments rather than challenge existing legislative actions. Review by the Attorney General may address specific legal concerns or provide legal opinions but does not constitute a formal challenge to legislation.
