Auer v. Robbins in Illinois Law

How Auer v. Robbins applies in Illinois: state-specific rules, key cases, and bar exam notes for Administrative Law.

State Approach

Illinois courts recognize the principle of Auer deference, allowing agencies to interpret their own regulations. However, this deference is applied with caution, particularly when agency interpretations can lead to significant changes in policy or when not grounded in the agency's expertise.

State Rule
In Illinois, Auer deference applies only when an agency's interpretation of its regulation is both reasonable and does not conflict with the regulation's text.
Significant State Cases

Comparison to Federal Law

While both Illinois and federal law generally adhere to Auer deference, Illinois courts have demonstrated more scrutiny regarding the reasonableness of agency interpretations. This cautious approach reflects a separation of powers concern that is not always present in federal cases.
