During criminal proceedings, suspects with intellectual disabilities (ID) are confronted with the criminal justice system, whose rules and procedures are difficult to understand even for individuals with no disability. Without assistance and the consideration of their special communicative needs by the involved professionals, they have lower chances of obtaining procedural justice than do individuals with no disability. Moreover, negative attitudes and myths about ID may influence the case assessment by the parties involved, and may thus unnoticedly affect a trial's proceedings and outcome. Hence, the norm of equality before the law depends essentially on it being implemented by the representatives of the forensic and law professions. To date, no study has systematically analyzed the situation of offenders with ID in Switzerland. The goal of the present exploratory study was to fill this gap with respect to sexual offence cases. With a qualitative content analysis records of criminal proceedings in two Swiss cantons concerning sexual offences have been analyzed as to which extent the parties involved in the proceedings refer to myths of ID and sexual violence.
