(g) Notwithstanding Section 455.5 or 1708, or any other provision of law, except as otherwise provided in Section 848.7 or in this subdivision with respect to recovery property that has been made the basis for the issuance of recovery bonds and with respect to any associated fixed recovery tax amounts, the financing order, the fixed recovery amounts and any associated fixed recovery tax amounts shall be irrevocable, and the commission shall not have authority either by rescinding, altering, or amending the financing order or otherwise, to revalue or revise for ratemaking purposes, the recovery costs or the costs of recovering, financing, or refinancing the recovery costs, determine that the fixed recovery amounts, any associated fixed recovery tax amounts or rates are unjust or unreasonable, or in any way reduce or impair the value of recovery property or of the right to receive any associated fixed recovery tax amounts either directly or indirectly by taking fixed recovery amounts or any associated fixed recovery tax amounts into account when setting other rates for the recovery corporation or when setting charges for the Department of Water Resources; nor shall the amount of revenues arising with respect thereto be subject to reduction, impairment, postponement, or termination.
