Chapter 17 maps out the key ‘decision points’ in the prosecution of sexual assault offences. These decision points extend from reporting to the police, through the handling of cases by various offices of the Director of Public Prosecutions (DPP) and to procedures involved in the trial of sexual offences. At each of these decision points, cases are filtered out, including because of the demands imposed on complainants. This process—referred to as ‘attrition’—may lead to offences not being reported and cases being unnecessarily withdrawn or dismissed.
