Insurer's Statutory Defences: Section 150 MV Act Explained

Against a third party's claim, the insurer is not an ordinary contracting party free to plead every term of its policy: section 150 lists the only defences it may raise, and the Supreme Court has spent six decades narrowing even those. Itbar Singh closed the list, Skandia read breach to mean wilful breach, and the modern law leaves the insurer defending rarely and recovering afterwards more often.

1. The statutory list: section 150(2)

• Use conditions: the vehicle used for hire or reward without a permit to ply for hire, for organised racing or speed testing, for a purpose not allowed by the permit (transport vehicles), or a two wheeler driven without the side car the policy requires attached.
• Driver conditions: driving by a person named as excluded, by one not duly licensed or disqualified, or under the influence of alcohol or drugs within section 185.
• War family: liability caused by war, civil war, riot or civil commotion.
• Policy attacks: the policy obtained by non disclosure or false statement of a material fact, and non receipt of the premium under the Insurance Act's section 64VB.
• Procedure: the insurer must receive notice of the proceeding and may be made a party to defend on these grounds; awards against the insured otherwise bind it.

• Onus on the insurer: each defence must be pleaded and proved by the insurer, fake licence cases included, with the owner's reasonable care the standard on that branch.
• Materiality and causation: the breach must bear on the accident in the manner the case law requires; a technical breach unconnected to the harm does not shift the loss.
• Effect of success: even a proved defence rarely sends the victim away; the standing practice directs the insurer to satisfy the award and recover from the insured, the pay and recover doctrine in operation.
• Against the insured himself, none of this protection applies: the own damage layer is ordinary contract, and the same breach that failed against the victim may succeed against the owner.

4. Quick Revision

1. Shut out every unlisted defence at the threshold.
2. Demand proof of wilfulness, not bare breach.
3. Test the breach's bearing on the accident.
4. Notice to the insurer before any binding award.
5. Reserve contract rigour for the own damage layer.

5. Frequently Asked Questions

Why can the insurer not rely on every clause of its own policy?

Because the policy serves a statute, not only a bargain. The cover exists by compulsion for the protection of people who never saw the contract, and if every exclusion and warranty bound them, the compulsion would protect no one: insurers would draft their way out of the very risk the law makes them carry. The statute therefore strikes the deal Itbar Singh enforced, a short list of defences reflecting serious misuse, and full freedom of contract preserved in the insurer's recourse against its own insured. The same structure explains why terms like depreciation, garaging warranties or geographical limits never appear in third party litigation: they are real terms, enforceable in the contractual relationship, and simply irrelevant to the statutory one.

Is drunk driving by the owner's driver a sure defence for the insurer?

It is a listed defence, but the Skandia gloss still applies. Driving under the influence within section 185 appears in the statutory list, yet what defeats cover is the insured's breach, so the insurer must connect the drunkenness to the insured's knowledge or connivance, an owner who knowingly sent out a drinking driver standing differently from one whose employee drank secretly on the route. Tribunals also require proof of the influence itself to the section's standard, breath or blood evidence or convincing testimony, not the bare smell of alcohol in a police report. And as everywhere in this chapter, success usually means recovery rights rather than the claimant's dismissal: the drunk driving goes to who finally bears the award, not to whether the widow is paid.

What notice must the insurer get, and what if it was never made a party?

The section conditions the award's binding force on notice: the insurer must receive notice of the proceeding through the court or tribunal, and on notice it may apply to be joined and defend on the listed grounds. An award passed without notice does not bind the insurer, which can resist execution and compel a rehearing on its defences, so claimants' counsel implead the insurer as a matter of course and the DAR regime routes the papers to its nodal officer early. The converse is equally settled: an insurer duly noticed and joined cannot later complain, and its statutory right to defend does not extend to contesting quantum or negligence at large except where it obtains the special permission the Act provides for cases of collusion or the insured's absence.
