Silence Matters: A survey of the right to silence in the summary jurisdiction of New South Wales

There is a scant existing literature on the relationship between the right to silence and its effect on convictions in Australia and comparable jurisdictions. Existing research has downplayed its significance in the face of various ‘law and order’ interventions seeking to limit its operation. This study is one of the largest of its kind, surveying over 1,000 charges to empirically assess the frequency of use and the effects of silence rights (the right to silence, privilege against self-incrimination and burden of proof) on conviction, in relation to a particular set of charges laid against a specific group of marginalised defendants in the Local Court summary jurisdiction of NSW. Adding to the existing literature, this study shows empirically how silence rights operate within an Australian summary jurisdiction for a specific group of criminal defendants who are significantly socially marginalised. In the process, it demonstrates that the use of silence rights is significant for this group, mostly in non-regulatory criminal matters. In this respect, silence rights can be understood to correlate with rates of conviction, mitigation of criminal sentencing and the practice of charge-bargaining.
