The Gauhati High Court has underscored the doctrine of estoppel in motor accident claims, setting aside a compensation award where the insurer adopted mutually exclusive positions in two parallel cases arising from the same fatal accident. The judgment reinforces that litigants cannot approbate and reprobate, especially when the same tribunal adjudicates overlapping claims with identical facts.
Background & Facts
The Dispute
On 20.09.2011, Prasanta Boro, a carpenter, was fatally injured when a Tata Dumper Tipper Truck bearing registration No. AS-01-DC-9740, driven by Sri Tutumoni Gharphalia, collided with his motorcycle on National Highway near Kamarkuchi, Kamrup (R), Assam. Prasanta Boro died on the spot. His co-rider, Babul Sonowal, succumbed to injuries the next day. A criminal case under Sections 279, 338, and 304(A) IPC was registered at Sonapur Police Station as Case No. 211/2011. Two Motor Accident Claims (MAC) were filed before the Motor Accident Claims Tribunal No. 1, Kamrup: MAC Case No. 1747/2011 by the dependants of Prasanta Boro and MAC Case No. 2257/2011 by the dependants of Babul Sonowal.
Key Facts
- The offending vehicle, AS-01-DC-9740, was owned by M/s MBL Infrastructure Ltd.
- The driver, Sri Tutumoni Gharphalia, was employed by the owner.
- The claimant in MAC Case No. 1747/2011 alleged the vehicle was insured with National Insurance Company Limited under Policy No. 101800/31/11/6300002124.
- The insurance company filed an additional written statement in MAC Case No. 1747/2011 asserting that the vehicle AS-01-DC-9740 was not insured under that policy, claiming the policy number corresponded to a different vehicle, MP-19-HA-1203.
- In MAC Case No. 2257/2011, filed by the dependants of the co-rider, the same insurance company, represented by the same officer, did not dispute insurance coverage and admitted liability.
- The Tribunal in MAC Case No. 2257/2011, by order dated 03.06.2016, held the insurer liable and awarded Rs. 15,17,500/- with 6% interest.
- The insurer did not appeal that award and paid the compensation.
- In MAC Case No. 1747/2011, the same Tribunal, by order dated 06.03.2017, absolved the insurer and imposed liability on the vehicle owner, awarding Rs. 11,90,000/-.
- The seizure list (Exhibit-3) revealed that the engine number and chassis number of the offending vehicle matched those in the insurance policy (Exhibit A) issued for MP-19-HA-1203.
- The seizure list also recorded a different policy number, 101800/1/11/0300002174, issued by National Insurance Company for AS-01-DC-9740, valid until 30.08.2012 - a fact overlooked by the Tribunal.

The Parties' Positions
For the Appellants
- The insurer’s contradictory stance in twin cases violates the principle of estoppel and approbation and reprobation.
- The Tribunal failed to reconcile the discrepancy between the policy number in the claim petition and the one recorded in the seizure list.
- The engine and chassis numbers matched between the seized vehicle and the policy document, indicating a clerical error in registration number, not lack of insurance.
- The insurer’s prior admission of liability in the other case binds it under the doctrine of judicial estoppel.
For the Respondent (Insurance Company)
- No appearance was made by the insurer’s counsel in the appeal.
- The insurer had denied coverage in MAC Case No. 1747/2011 based on verification of policy records.
- The policy number cited in the claim petition did not match the policy issued by the insurer.
Relief Sought
The appellants sought:
- Setting aside of the Tribunal’s order dated 06.03.2017
- Holding the insurer liable for compensation
- Enhancement of compensation to Rs. 17,42,000/- with 6% interest from the date of filing
- Alternatively, remand for fresh adjudication
The Legal Issue
Can a motor insurance company be absolved of liability in a MAC claim when it has previously admitted the same vehicle’s coverage in a parallel claim arising from the same accident, and when documentary evidence suggests a clerical mismatch rather than absence of insurance?
Arguments Presented
For the Appellant
The learned counsel relied on the settled legal principle that a party cannot take inconsistent stands in judicial proceedings. Citing State of U.P. v. Mohd. Noor and S. P. Chengalvaraya Naidu v. Jagannath, the appellant argued that the insurer’s contradictory positions in twin cases before the same Tribunal vitiated the fairness of the proceedings. The insurer’s prior admission of liability in MAC Case No. 2257/2011, followed by its denial in MAC Case No. 1747/2011, amounted to judicial approbation and reprobation. The Tribunal’s failure to investigate the discrepancy between the policy number in the seizure list and the claim petition rendered the award unsustainable.
For the Respondent
No arguments were presented by the insurer or the owner/driver, as none appeared before the High Court.
The Court's Analysis
The Court observed that the same Presiding Officer of the Tribunal had adjudicated both MAC cases, and both records were before him. The insurer’s admission of liability in MAC Case No. 2257/2011 - which was not appealed and was fully satisfied - created a binding precedent on the same facts. The Court emphasized that the doctrine of estoppel applies with greater force when the same tribunal is seized of overlapping claims.
"The insurer cannot be permitted to approbate and reprobate - first accepting liability in one case and then denying it in another, on identical facts, before the same adjudicatory forum."
The Court further noted that the seizure list recorded a valid policy number (101800/1/11/0300002174) for AS-01-DC-9740, issued by the same insurer, valid until 30.08.2012 - a fact the Tribunal failed to consider. The engine and chassis numbers in the policy document (Exhibit A) matched those of the offending vehicle, indicating that the policy was likely issued for AS-01-DC-9740 but misrecorded as MP-19-HA-1203 due to administrative error.
The Court held that the Tribunal’s conclusion that the vehicle was uninsured was based on a superficial comparison of registration numbers, ignoring the more critical identifiers - engine and chassis numbers - which are unique and immutable. The failure to investigate the source of the discrepancy, or to verify whether the policy number in the seizure list was genuine, rendered the finding arbitrary.
The Court concluded that the insurer’s conduct was inconsistent, misleading, and prejudicial to the claimants. The Tribunal’s award, therefore, was legally unsustainable.
The Verdict
The appeal was allowed. The impugned judgment and award dated 06.03.2017 was set aside. The matter was remanded to the Motor Accident Claims Tribunal No. 1, Kamrup, for fresh adjudication in light of the insurer’s contradictory stance and the documentary evidence of a valid policy. The Tribunal was directed to determine whether the policy number recorded in the seizure list (101800/1/11/0300002174) was issued by the insurer for AS-01-DC-9740 and, if so, to hold the insurer liable. The Tribunal was directed to complete the proceedings within three months of receipt of the TCR. The question of compensation amount was left open for reconsideration on remand.
What This Means For Similar Cases
Contradictory Insurance Stands Are Judicially Unacceptable
- Practitioners must raise estoppel as a ground of challenge whenever an insurer takes inconsistent positions in parallel MAC claims.
- The same tribunal’s prior finding of liability in a related case creates a binding presumption that must be rebutted with cogent evidence.
Engine and Chassis Numbers Trump Registration Numbers
- In MAC claims, registration number mismatches are not conclusive if engine and chassis numbers match the policy document.
- Courts must prioritize unique vehicle identifiers over registration numbers, which are prone to clerical errors.
Administrative Errors Cannot Defeat Victim Compensation
-
Insurance companies cannot exploit typographical errors in policy records to deny liability.
-
The burden shifts to the insurer to prove the policy was issued for a different vehicle, not merely to assert a mismatch.
-
Always cross-check seizure lists, RC books, and policy documents for engine/chassis number consistency.
-
Where an insurer admits liability in one case, treat its denial in another as a potential abuse of process.
-
File applications under Section 166(3) MV Act to compel insurers to produce policy records from their central offices.
