The Cost of justice: vicarious trauma and the legal system's duty of care to jurors

Jurors play a critical role in the administration of justice, yet their compulsory exposure to graphic and distressing evidence during criminal trials is often overlooked in discussions of mental health and legal reform. This paper investigates the psychological impact of jury service in trials involving murder, domestic violence, sexual assault, and child abuse, where laypeople are required to view autopsy photographs, listen to emergency calls, and assess disturbing testimonies without any formal training or mandatory psychological support. While vicarious trauma, secondary traumatic stress, and moral injury are recognised in research on law enforcement, social work, and healthcare, there is limited acknowledgement that no professional group consistently receives adequate trauma prevention or recovery support. This gap is particularly concerning for jurors, who are laypeople compelled to participate in the justice process. Drawing on legal case studies, psychiatric research, and international precedent, this paper argues that the justice system imposes an invisible emotional burden on jurors while offering limited, inconsistent, and mostly reactive support. Although applicable to many countries, particular attention is given to Australian jurisdictions, where counselling services are sparse and optional, and where juror confidentiality laws restrict therapeutic disclosures. This research also considers the legal and ethical implications of exposing untrained civilians to traumatic material and explores whether the state could, or should, bear legal liability for post-trial psychological harm. Ultimately, this paper calls for the introduction of clearly defined trauma-informed jury procedures, including pre-trial psychological briefings, structured debriefings, and systemic reform, to acknowledge juror well-being as a necessary component of fair and ethical justice.
