The expert witness—psychologists and judicial gatekeepers in the family court.

This article examines the role and challenges of psychologists as expert witnesses in Australian family law custody disputes, focusing on the reliability, admissibility, and potential biases of their testimony. It highlights that judges often rely heavily on expert opinions despite inconsistencies in disciplinary perspectives, lack of standardized methods, and insufficient transparency regarding the experts' specialized knowledge and assumptions. Through analysis of recent Family Court appeal cases, the article illustrates how flawed or biased expert testimony can significantly impact judicial decisions affecting the best interests of children, underscoring the need for clearer standards defining specialist expertise and stricter enforcement of reporting requirements. The study also emphasizes the limitations of the appeals process and calls for improved judicial and regulatory mechanisms to ensure accountability and reduce risks associated with expert evidence in family law proceedings.
