As in other problem-solving courts, the judge in a mental health court plays a larger role than a judge in a conventional court. Problem-solving courts rely upon the active use of judicial authority to solve problems and to change the behavior of litigants. For instance, in a problem-solving court, the same judge presides at every hearing. The rationale behind this is not only to ensure that the presiding judge is trained in pertinent concepts, such as mental illness, drug addiction, or domestic violence, but also to foster an ongoing relationship between the judge and participants. Although the judge has final say over a case, mental health courts also take a team approach in which the defense counsel, prosecutor, case managers, treatment professionals, and community supervision personnel (for example, probation) work collaboratively to, for example, craft systems of sanctions and rewards for offenders in drug treatment. Many mental health courts also employ a full-time coordinator who manages the docket and facilitates communication between the different team members.
