Except as herein otherwise provided, if during the pendency of any matter in any other court in which a person is charged with a crime, offense or violation, it is discovered that such person was a juvenile at the time of the commission of the conduct charged, such court shall immediately transfer the action to the Family Part. The action shall not, however, be transferred if it involves any violation by a juvenile of Title 39 of the Revised Statutes (motor vehicles) enumerated by N.J.S. 2A:4A-23.
Upon transfer of an action to the Family Part, a new complaint shall be filed therein and the matter shall thereafter proceed as if the action had been instituted in that court.
