Article 5
Section 19

The determination of guilt or innocence, the detention, and the custody of a person who is alleged to have committed a crime prior to his seventeenth birthday shall be pursuant to special juvenile procedures which shall be provided by law. However, the legislature may (1) by a two-thirds vote of the elected members of each house provide that special juvenile procedures shall not apply to juveniles arrested for having committed first or second degree murder, manslaughter, aggravated rape, armed robbery, aggravated burglary, aggravated kidnapping, attempted first degree murder, attempted second degree murder, forcible rape, simple rape, second degree kidnapping, a second or subsequent aggravated battery, a second or subsequent aggravated burglary, a second or
subsequent offense of burglary of an inhabited dwelling, or a second or subsequent felony-grade violation of Part X or X-B of Chapter 4 of Title 40 of the Louisiana Revised Statutes of 1950, involving the manufacture, distribution, or possession with intent to distribute controlled dangerous substances, and (2) by two-thirds vote of the elected members of each house lower the maximum ages of persons to whom juvenile procedures shall apply, and (3) by two-thirds vote of the elected members of each house establish a procedure by which the court of original jurisdiction may waive special juvenile procedures in order that adult procedures shall apply in individual cases. The legislature, by a majority of the elected members of each house, shall make special provisions for detention and custody of juveniles who are subject to the jurisdiction of the district court pending determination of guilt or innocence.
