The Magistrate hears and determines prosecutions and criminal causes in the Mayor's Court that are within its jurisdiction. In hearing and determining such prosecutions and causes, the Magistrate has the same powers, duties, and authority as does the Mayor if she were to conduct Mayor's Court, including the ability to hear and determine prosecutions and causes in general, including but not limited to the power and authority to decide the prosecution or cause, enter judgment, and impose sentence. The appointment of a Magistrate does not preclude the Mayor from also hearing and determining prosecutions and criminal causes in the Mayor's Court that are within the jurisdiction of the Mayor's Court.
