(a) All laws or parts of laws, both general and local, and any rules or portions of rules adopted by the Supreme Court which conflict with this chapter are expressly repealed. The provisions of this chapter are cumulative and shall not be construed to repeal or supersede any laws not inconsistent herewith.
(b) The provisions of this chapter are severable. If any part of this chapter is declared invalid or unconstitutional, that declaration shall not affect the part which remains.
(c) The provisions of this section shall not be construed as repealing any local act which is in effect upon the passage of this chapter and which provides for the collection of additional court costs to be placed in a fund in the county treasury for the general use and maintenance of the juvenile probation office. Any local acts are amended so as to provide that the funds so collected and deposited in the county treasury shall not be utilized for the purpose of supplementing the salary of any juvenile probation officer, but shall, after the effective date of this chapter, be utilized for probation service activities as may be directed by the juvenile court judge, the provisions of any local act to the contrary notwithstanding.
