P Cooper and M Mattison, “Intermediaries, vulnerable people and the quality of evidence: an international comparison of three versions of the English intermediary model” (2017) 21(4) The International Journal of Evidence & Proof 351.

Since 2004, witness intermediaries have been utilised across the justice system in England and Wales. Two witness intermediary schemes based on the English model have also been introduced in Northern Ireland (2013), and more recently, in New South Wales, Australia (2016). The purpose of the intermediary in these jurisdictions is to facilitate the questioning of vulnerable witnesses, but there are clear differences in the application of the role. This paper presents the first comparative review of the three related intermediary models, and highlights the pressing need for further research into the efficacy and development of the role in practice.
