The influential Victorian appellate judgment of R v Verdins [2007] VSCA 102 provided a sentencing framework for "impaired mental functioning" not only in Victoria but in other Australian jurisdictions. Following the judgment of Director of Public Prosecutions (Vic) v O'Neill (2015) 47 VR 395; [2015] VSCA 325, it appeared that personality disorders were not considered within the scope of the Verdins principles. In Brown v The Queen [2020] VSCA 212, the decision of the Victorian Court of Appeal broadened the potential for impaired mental functioning to include personality disorders as relevant to moral culpability. However, it is also noted that there are several limits on this.
