(a) Any side letter, appendix, or other addendum to a properly ratified memorandum of understanding that requires the expenditure of two hundred fifty thousand dollars ($250,000) or more related to salary and benefits and that is not already contained in the original memorandum of understanding or the Budget Act, shall be provided by the Judicial Council to the Joint Legislative Budget Committee. The Joint Legislative Budget Committee shall determine within 30 days after receiving the side letter, appendix, or other addendum whether it presents substantial additions that are not reasonably within the parameters of the original memorandum of understanding and thereby requires legislative action to ratify the side letter, appendix, or other addendum.
(b) A side letter, appendix, or other addendum to a properly ratified memorandum of understanding that does not require the expenditure of funds shall be expressly identified by the Judicial Council if that side letter, appendix, or other addendum is to be incorporated in a subsequent memorandum of understanding submitted to the Legislature for appropriation or statutory amendment.
