Prosecutorial Decisions in Adult Sexual Assault Cases

Prosecution agencies are often criticised for their performance in prosecuting sexual assault. A lack of external transparency means there is little knowledge about the specific criteria used in decisions to proceed with or discontinue prosecutions. Understanding the factors that impact on the exercise of prosecutorial discretion therefore constitutes an important step towards improving criminal justice outcomes in sexual assault prosecutions. This paper analyses prosecutorial decisions to proceed with or discontinue prosecution in a sample of adult sexual assault cases. The results indicate that case decisions are primarily based on evidentiary considerations related to the ability to secure a conviction, but they also raise questions about the handling of cases involving prior relationships.
