Once the attorney general issues a certificate of no objection pursuant to RCW 29A.93.020, or once the attorney general's certificate of no objection of a covered policy is upheld by a court in the case of an appeal under RCW 29A.93.030(1)(a), whichever is later, an action against the political subdivision based on the same covered policy may not be brought within four years of the approval of that covered policy so long as the political subdivision does not enact a change to or deviation from the approved covered policy during the four-year period that would otherwise give rise to an action under this chapter or chapter 29A.92 RCW. This section does not preclude an appeal under RCW 29A.93.030(1)(a) or an action by the attorney general under RCW 29A.93.020(3)(d).
