Background

Dolton police officer Theresa Guess was injured in a September 2018 on-duty vehicle collision while responding to a call with lights and sirens activated. Before the collision, she had no history of seizures or neurological or psychological conditions affecting her police work. Soon afterward, she began experiencing headaches, loss of consciousness, shaking, confusion, and other seizure-like symptoms that prevented her from returning to duty.

Guess initially received treatment for epilepsy, but later testing supported a diagnosis of psychogenic nonepileptic seizures rather than epileptic seizures. The Pension Board found her disabled but concluded that the collision did not cause or contribute to her disability, finding her entitled to nonduty rather than line-of-duty disability benefits. On administrative review, the circuit court reversed that decision.

The Court’s Holding

The appellate court affirmed the circuit court and reversed the Pension Board’s administrative decision. It held that the Board’s finding that Guess’s on-duty collision was not a causative factor contributing to her disability was against the manifest weight of the evidence.

The court emphasized that Illinois law does not require an on-duty accident to be the sole, primary, or direct cause of a disability; it need only be a contributing causative factor. The Board’s psychiatrist, Dr. Weine, expressly linked Guess’s psychiatric disabilities to the collision. By contrast, the court found the neurologists’ causation statements either focused primarily on whether Guess had epilepsy, ambiguous as to the cause of her psychogenic seizures, or insufficient because they addressed only whether the accident was the disability’s direct cause. The court also found no evidentiary basis for treating Guess’s later misdiagnosis or medical treatment as negating causation.

Key Takeaways

  • A police officer seeking line-of-duty disability benefits need not prove that an on-duty accident was the sole, primary, or direct cause of the disability.
  • A pension board’s causation finding may be reversed under the manifest-weight standard when the opposite conclusion is clearly evident from the medical record.
  • On this record, the Board unreasonably discounted its psychiatrist’s express causation opinion while relying on neurologists’ statements that the court considered ambiguous or legally insufficient.

Why It Matters

The decision illustrates that a psychiatric condition, including psychogenic nonepileptic seizures, may support line-of-duty disability benefits when an on-duty event contributed to the disabling condition. The psychological nature of the diagnosis does not itself sever the causal connection to a workplace accident.

The order also shows that deferential administrative review is not a rubber stamp. A reviewing court may reject a pension board’s factual determination when its treatment of the medical evidence leaves the contrary conclusion clearly evident.
