(Applicable to cases initiated on or after September 7, 2004)
(a) Commencement of Criminal Proceeding. A criminal proceeding shall be commenced in the District Court by a complaint and in the Superior Court by an indictment, except that if a defendant is charged in the District Court with a crime as to which the defendant has the right to be proceeded against by indictment and the defendant has waived the right to an indictment pursuant to subdivision (c), the Commonwealth may proceed in the Superior Court upon the complaint.(b) Right to Indictment. A defendant charged with an offense punishable by imprisonment in state prison shall have the right to be proceeded against by indictment except when the offense charged is within the concurrent jurisdiction of the District and Superior Courts and the District Court retains jurisdiction.(c) Waiver of Indictment.(1) Right to Waive Indictment. A defendant charged in a District Court with an offense as to which the defendant has the right to be proceeded against by indictment shall have the right, except when the offense charged is a capital crime, to waive indictment, unless the Commonwealth proceeds by indictment pursuant to subdivision (e) of this rule.(2) Procedure for Waiving Indictment. The defendant may waive the right to be proceeded against by indictment by filing a written waiver of that right in the District Court prior to the determination to bind the case over to the Superior Court for trial. The District Court may for cause shown grant relief from that waiver. After the determination by the District Court to bind the case over to the Superior Court for trial, the defendant may waive the right to be proceeded against by indictment by filing a written waiver of that right, with the consent of the prosecutor, in the Superior Court.(d) Transmission of Papers. If the defendant is bound over to the Superior Court for trial after a finding of probable cause or after the defendant waives a probable cause hearing, the clerk of the District Court shall transmit to the clerk of the Superior Court a copy of the complaint and of the record; the original recognizances; a list of the witnesses; a statement of the expenses and the appearance of the attorney for the defendant, if any is entered; the waiver of the right to be proceeded against by indictment, if any is executed; the pretrial conference report, if any has been filed; and the report of the department of mental health as to the mental condition of the defendant, if such report has been filed under the provisions of the General Laws.(e) Indictment after Waiver. Notwithstanding the defendant’s waiver of the right to be proceeded against by indictment, the prosecuting attorney may proceed by indictment.(f) Probable Cause Hearing. Defendants charged in a District Court with an offense as to which they have the right to be proceeded against by indictment and defendants charged in a District Court with an offense within the concurrent jurisdiction of the District and Superior Courts for which the District Court will not retain jurisdiction, have the right to a probable cause hearing, unless an indictment has been returned for the same offense. If the District Court finds that there is probable cause to believe that the defendant committed the crime or crimes alleged in the complaint, the court shall bind the defendant over to the Superior Court. If the District Court finds that there is no probable cause to believe that the defendant committed the crime or crimes alleged in the complaint, the court shall dismiss the complaint.(g) The Complaint Process(1) Procedure for Obtaining a Complaint. Any person having knowledge, whether first hand or not, of the facts constituting the offense for which the complaint is sought may be a complainant. The complainant shall convey to the court the facts constituting the basis for the complaint. The complainant’s account shall be either reduced to writing or recorded. The complainant shall sign the complaint under oath, before an appropriate judicial officer.(2) Probable Cause Requirement. The appropriate judicial officer shall not authorize a complaint unless the information presented by the complainant establishes probable cause to believe that the person against whom the complaint is sought committed an offense.
