Legal Commentary & Landmark Judgments: Section 153
Section 153 of the Motor Vehicles Act, 1988 establishes a strict statutory bar against bilateral or private settlements between insurers and insured persons that prejudice or extinguish third-party claims, mandating that no compromise regarding third-party liability is legally valid unless the third-party victim or legal representatives are consenting parties thereto, subject to mandatory Claims Tribunal scrutiny.
In MACT Lok Adalats or pre-trial settlement negotiations, claimants' counsel must ensure that any joint memo of compromise is formally presented before the Tribunal under Section 153(2) with full verification of the victim's identity and banking particulars. For insurers, never execute bilateral discharge vouchers with the insured without impleading the victim, as such instruments are void against third parties and will be summarily rejected by the Tribunal.
