All proceedings in which the insolvent insurer is a party in any court in this territory shall be stayed for 60 days from the date the insolvency is determined to permit proper defense by the Association of all pending causes of action. As to any covered claims arising from a judgment under any decision, verdict, or finding based on the default of the insolvent insurer or its failure to defend an insured, the Association, either on its own behalf or on behalf of such insured, may apply to have such judgment, order, decision, verdict, or finding set aside by the same court or administrator that made such judgment, order, decision, verdict, or finding and shall be permitted to defend against such claim on the merits.
