Massachusetts has a unique system for certain criminal complaints, where both a police officer or private individual can apply for a criminal complaint and a clerk magistrate will decide whether there is probable cause for a criminal complaint to be issued. This process is available for most misdemeanor crimes and some felony crimes where an individual has not been arrested. A hearing before a clerk magistrate—also known as a “show cause” hearing—serves an important function in the Massachusetts criminal justice system because it screens out certain potential complaints at an early stage without creating a criminal record for the accused. If the clerk magistrate does not find probable cause, the clerk magistrate will not issue a criminal complaint. If the clerk magistrate finds probable cause, he or she can either issue a criminal complaint or exercise discretion and decide not to issue a complaint.
