(a) Commencing July 1, 1987, the circuit judges and District Attorney of the Twelfth Judicial Circuit shall each receive a local salary supplement in the amount of one thousand one hundred seventy dollars ($1,170) per month to be paid on a share and share alike basis from county funds belonging to the two counties comprising the circuit.
(b) Commencing October 1, 1988, and on the first day of October of the years 1989, 1990, 1991, and 1992, the circuit judges and the District Attorney of the Twelfth Judicial Circuit shall each be entitled to receive an annual increase in local salary supplement in an amount equal to two percent of the total amount of any state salary plus any local salary supplement that each circuit judge is receiving on the first day of the aforementioned fiscal years. Such local salary supplements shall be paid on a share and share alike basis from county funds belonging to the counties comprising the circuit. Provided, however, that in any year that funds generated to the counties general fund from the worthless check fees shall be terminated for any reason, or the amount generated the previous year is not sufficient to cover a two percent increase, then under those standards, a county governing body of either of the two counties in the circuit is hereby authorized and empowered to either delay for a time certain or totally nullify an increase in any local salary supplement, as provided herein, by duly adopting and spreading upon its minutes a resolution stating its intent to so delay or nullify such increase. Provided further, that the judges and the district attorney shall not be entitled to receive more than one local salary supplement increase, as herein provided, during the fiscal year regardless of any portion or the whole of any local salary supplement increase that may have been delayed or nullified by appropriate aforementioned action by a county governing body. The total amount of any local salary supplements for the judges and the district attorney that is in effect on October 1, 1993, shall remain operative until the Legislature provides further for such local supplements.
(c) All local salary supplements and any increases therein provided by this section for the judges and District Attorney of the Twelfth Judicial Circuit shall be in lieu of any local salary supplements heretofore provided by law for such judges and district attorney.
