Delegates must apply the version of the GARP M that is in force on the day the MRCA PI claim is lodged. The GARP M 2026, which includes the new baseline impairment rating methodology, only applies to claims for MRCA PI lodged on and after 1 July 2026. Any MRCA PI claims lodged before 1 July 2026 must continue to be assessed under the earlier version of GARP M.
Claims resulting in interim determinations under the MRCA
When delegates are finalising a claim after 1 July 2026 following an interim determination under the MRCA, the version of the GARP M in force on the day the original MRCA PI claim was lodged must be applied to the claim.
