(a) The Superior Court may, from time to time, adopt and promulgate general rules which prescribe and regulate the form and manner of process, pleading, practice and procedure governing criminal proceedings in the Superior Court from their inception to their termination, including such proceedings before inferior courts and justices of the peace as are preliminary to indictment or information filed in the Superior Court.
(b) Such rules shall not abridge, enlarge or modify the substantive rights of any person, and shall preserve the right of trial by jury as at common law and as declared by the statutes and Constitution of this State.
(c) The Rules of Criminal Procedure for the Superior Court adopted and promulgated by the Supreme Court prior to the enactment of this Code shall take effect upon the enactment of this Code. Any amendments of or supplements to such Rules which the Superior Court may hereafter adopt and promulgate shall take effect upon such date as the Superior Court shall fix in its order adopting and promulgating such amendments or supplements. After the effective date of any rule adopted and promulgated under this section, all laws inconsistent or in conflict therewith shall be of no further force or effect.
(d) Nothing in this title, anything therein to the contrary notwithstanding, shall in any way limit, supersede or repeal any such rules heretofore prescribed under authority of law.
