The Illinois Appellate Court ruled on June 26, 2026, in the case of Berrigan v. City of Chicago Department of Animal Care and Control, reversing a previous dangerous dog designation and restitution order against Derry Berrigan. This decision affects pet owners and animal control regulations in Chicago, highlighting the complexities of animal behavior and legal responsibility.

The case began when Berrigan's dog, Ella, was involved in a fight with another dog in a Chicago park, leading to citations from the City of Chicago Department of Animal Care and Control (CACC). Following an administrative hearing, an administrative law judge (ALJ) found Berrigan liable for failing to control her dog and declared Ella a dangerous animal. Berrigan contested these findings, leading to a review by the circuit court, which upheld the fine but reversed the dangerous animal designation and vacated the restitution order.

The dispute arose after an incident on December 12, 2020, when Ella attacked a dog owned by Carter Yeatman in Solti Garden, a dog-friendly area in Grant Park. Yeatman claimed his dog, Josie, suffered severe injuries requiring surgery, leading to veterinary bills totaling over $2,600. Berrigan, who represented herself during the hearings, argued that Yeatman provoked the encounter and that she had offered to share the veterinary costs.

The case progressed through the administrative process, where the ALJ found Berrigan liable for not restraining her dog and upheld the dangerous animal designation. However, the circuit court later reviewed the case and found that the investigation conducted by CACC was not thorough enough to support the dangerous animal designation. The court stated, "I believe the investigation was not thorough... it’s hard for me to be comfortable with the conclusion that the City reached in terms of its filing of the claim here."

In its ruling, the Appellate Court agreed with the circuit court's assessment regarding the dangerous animal designation, stating that the evidence did not support the conclusion that Ella was a dangerous animal as defined by the municipal code. The court emphasized that the definition of a dangerous animal requires an absence of provocation, which was not sufficiently considered in the ALJ's findings.

The court also addressed the issue of restitution, which the circuit court vacated, stating that Berrigan's prior payment of part of the veterinary bill effectively satisfied the restitution claim. The Appellate Court ruled that the ALJ's restitution order was valid under the municipal code and that the circuit court had erred in vacating it. The court noted, "The ALJ's restitution order was authorized by Code section 7-12-030 and supported by the record. The sanction was neither arbitrary nor unreasonable."

The ruling from the Appellate Court has significant implications for pet owners and animal control policies in Chicago. It clarifies the standards for determining dangerous animals and the responsibilities of pet owners in controlling their pets. The decision also underscores the importance of thorough investigations in administrative proceedings to ensure fair outcomes.

Going forward, this ruling may influence how similar cases are handled in the future, particularly regarding the definitions of dangerous animals and the responsibilities of pet owners. The case highlights the need for clear guidelines in animal control laws to balance public safety with the rights of pet owners.

As for next steps, the City of Chicago Department of Animal Care and Control may consider appealing the Appellate Court's decision. However, details regarding any potential appeal or related cases were not available in the court filing.
