Summary

On December 12, 2020, Derry Berrigan's dog Ella attacked and severely injured another dog in Grant Park. The City of Chicago Department of Animal Care and Control (CACC) cited Berrigan for failure to restrain her animal and declared Ella a 'dangerous animal.' Following an administrative hearing, an ALJ found Berrigan liable, imposed a $500 fine, ordered $1,645.18 in restitution, and upheld the dangerous animal designation. On administrative review, the circuit court vacated the restitution award and reversed the dangerous animal determination, finding the investigation insufficiently thorough and the facts inadequate to support liability. CACC appealed.

The Illinois Appellate Court, First District, reversed on all contested issues. First, the court held that the circuit court improperly vacated the restitution award—an action expressly authorized by the ordinance—by substituting its own factual findings for the ALJ's credibility determinations regarding an alleged oral settlement agreement. Even if the award were unreasonable, outright vacatur was improper; remand to the agency was required. Second, applying de novo review, the court held that 'provocation' under Chicago Municipal Code section 7-12-020 is limited by its plain language to human conduct, making animal-on-animal provocation legally irrelevant to a dangerous animal determination. Third, the court held that Berrigan's totality-of-the-circumstances argument was forfeited because she failed to raise it before the ALJ.

This decision is significant for attorneys handling municipal administrative proceedings: it reinforces strict issue preservation requirements, confirms that courts may not engraft exceptions onto unambiguous ordinance language, and clarifies that circuit courts reviewing administrative sanctions must remand rather than independently resolve unaddressed factual questions.

Key Holdings

1. Under Chicago Municipal Code § 7-12-020, 'provocation' is limited by plain language to human conduct; provocation by another animal is not a legally cognizable defense to a dangerous animal determination.

2. A circuit court reviewing an administrative restitution award may not vacate the award outright based on its own factual findings; when the award is challenged as unreasonable or unsupported, the proper remedy is remand to the agency.

3. An argument not raised before the ALJ at the administrative hearing is forfeited and may not be raised for the first time in a specification of errors submitted to the circuit court on administrative review.

4. When a material factual question remains unaddressed by the agency, a reviewing court may not make an independent factual determination; it must remand to the agency for further proceedings.
