Illinois HB 3773
Illinois took a different route from New York City. Under HB 3773, using AI that ends up discriminating on a protected class is a civil rights violation in itself. That covers nine kinds of employment decision. The law names no audit and no assessment. It also bans using zip codes as a stand-in for protected classes.
