Subdivision 1. Generally. This rule is applicable when the prosecutor moves for certification and a child is alleged to have committed, after becoming fourteen (14) years of age, an offense that would be a felony if committed by an adult.
Subd. 2. First Degree Murder Acquisition. The district court has original and exclusive jurisdiction in criminal proceedings concerning a child alleged to have committed murder in the first degree after becoming sixteen (16) years of age. Upon the filing of a complaint or indictment charging a sixteen (16) or seventeen (17) year old child in adult court proceedings with the offense of first degree murder, juvenile court jurisdiction terminates for all proceedings arising out of the same behavioral incident.
