The criminal justice system is currently failing victims and witnesses with mental health problems. Last year, the influential House of Commons Justice Committee published their report into the Crown Prosecution Service (CPS) and identified mental health as a key area of weakness. They highlighted lack of support provided to victims and witnesses with mental health problems during the court process and an “institutional reluctance around being prepared to believe people with mental health problems as credible witnesses”, as I described it when I was called upon to give evidence to the Committee’s inquiry. In this article I outline the considerable barriers to justice faced by people with mental health problems, and what needs to change to ensure the justice system upholds everyone’s right to seek legal redress for crimes committed against them.
