Rule 30.03 - JOINDER AND TRANSFER OF CASES(a) All criminal charges of all defendants arising out of a single incident, including ordinance violations, shall be written into a single court on a single date. All matters shall be set in the division that would hear the most serious offense.(b) All cases filed against a given defendant at the same time, regardless of case category, shall be assigned to the same courtroom, except as otherwise provided by administrative order.(c) It shall be the responsibility of each judge to identify companion cases and to have them transferred to one courtroom, through the office of the Presiding Judge of the appropriate division.(d) Upon the motion of either the prosecuting authority or the defendant for inter-division transfer of subject type cases for the purpose of proffering a plea agreement and disposition of all cases, the motion shall be made before the assigned judge for transfer to the Presiding Judge of the division in which the most serious charge is pending. The Presiding Judge shall decide the motion to transfer. In the event the motion to transfer is granted, all the cases shall be transferred to the judge assigned to the pending case with the most serious class of offense to accept or reject the proffered plea agreement.(e) Upon the motion of any prosecuting authority or the defendant for intra-division transfer of subject type cases for the purpose of proffering a plea agreement and disposition of all cases, the cases shall be transferred to the assigned judge with the most serious class of offense or if the charges are of equal seriousness, the transfer will be to the assigned judge with the oldest case to decide the motion to transfer and to accept or reject the proffered plea agreement.(f) Cases involving a single defendant shall be randomly assigned, and unless otherwise ordered, shall remain so assigned throughout the pendency of the case, including any term of supervision, conditional discharge or probation. Any single defendant who has a pending case or who is currently on supervision, conditional discharge or probation in a felony courtroom shall have the new felony case assigned to the judge currently assigned to the oldest file.
(g) Felony cases involving co-defendants, defendants jointly charged or indicted, shall be heard by the same judge, and on motion of the court all co-defendants in a single case shall be transferred to the judge to whom the lowest numbered case is assigned. Any recusal or motion for substitution of judge filed by one co-defendant shall act to transfer all codefendants.(h) Failure to transfer cases in accordance with Rule 30.03 shall not be grounds for dismissal of criminal or quasi-criminal charges, unless justice so requires.Ill.
