The following paragraphs provide an outline of the specialist courts and a guide to the referral processes for each court. Whilst the legislation (as cited above) provides the foundation for practices and procedures in specialist courts, a number of these courts are in the process of restructure which may affect the current and future assessment procedures, eligibility criteria, and availability of interventions, treatment and other services. As specialist courts operate on the principles of evidence-based and best practice, they are necessarily subject to change from time to time.
