Abstract
This article examines some of the possible harmful effects of regulatory investigations, in particular that of trauma, on persons being investigated and those around them, the legal, ethical or regulatory duties or responsibilities of regulators in the case of such events, and programs currently available to prevent or ameliorate these effects. It concludes by describing what trauma-informed regulatory practice might look like and concludes that a trauma-informed approach to regulation can provide a model of justice that can be applied to persons adversely affected by investigations without derogating from a regulator's statutory purposes.
