A patient who says she was sexually assaulted by an employee at an Illinois residential treatment facility can proceed with direct liability claims against the facility, a state court ruled. The woman, suing as Jane Doe, alleged the facility failed to properly train, monitor, or supervise the employee or warn patients of a risk posed by him.

Why it matters

This case highlights the importance of behavioral health facilities ensuring proper protocols are in place to protect vulnerable patients from potential abuse or misconduct by staff members. The ruling allows the patient to pursue claims that the facility itself was negligent in its oversight and training.

The details

The Illinois Court of Appeals, First District, revived the woman's claims under the Illinois Gender Violence Act, saying the worker's alleged actions fell within the scope of his employment for purposes of the law. The facility had argued the worker's actions were outside the scope of his duties, but the court disagreed, allowing the direct liability claims to move forward.

  • The alleged sexual assault incident occurred at the Lemont, Illinois behavioral health facility.
  • The Illinois Court of Appeals, First District, issued its ruling on March 19, 2026.
