The suit filed by the United Public Servants union said the plan violates a law protecting the pension system as well as constitutional guarantees involving contracts between the government and retirees. The union represents more than 10,000 government workers and 2,300 retired ones.
Comment: The case could eventually set precedent important to Illinois. If Illinois ever amended its constitution to delete the pension protection clause, pension cuts would still be challenged under the Contracts Clause of the U.S. Constitution. That issue could be addressed in this case.
