Motor Accident Compensation| Original Wrongdoer Liable For Entire Injury Despite Intervening Act Contributing To Final Damage: Delhi High Court

The Court was considering an appeal by an insurance company challenging an award of compensation made on the footing that the victim's death was attributable to injuries sustained in a motor accident.

A Bench of Justice Anish Dayal observed: "The issue in this case relates to the chain of causation set in motion by the wrongful act of the driver/owner which allegedly is interrupted or snapped by intervening events. This introduces the problem of determining whether damage resulting after the intervention of the new act or event qualifies for an award of damages. An intervening act or human action, as opposed to intervening events/natural events, does not per se sever the chain of causation. The plaintiff can still be entitled to claim damages for all injury caused by the original wrongdoer, the person who set the chain in motion, even though the intervening act is one of the elements contributing to the final injury. An intervening act breaks the chain of causation only if it is in the nature of something unwarrantable, unreasonable, extraneous or extrinsic."

Advocate Pankaj Seth appeared for the appellant. Advocate Pankaj Gupta appeared for the respondent.

Background

The appeal arose from an award of the Motor Accident Claims Tribunal treating the proceedings as a death claim instead of an injury claim. The insurance company contended that the victim's death was not legally attributable to the injuries sustained in the accident, asserting that complications allegedly resulting from pain medication administered during treatment constituted an intervening cause breaking the chain of causation.

The claimants, on the other hand, maintained that the victim remained under continuous treatment following the accident and that the subsequent deterioration of his condition and eventual death formed part of the same uninterrupted causal chain.

The Court noted that the controversy was essentially one of tortious liability. It therefore proceeded to examine the principles governing causation, remoteness of damage and novus actus interveniens before applying them to the evidence on record.

Court's Observations

The Court observed that although claims under the Motor Vehicles Act arise under a statutory framework, they remain claims for damages founded upon tortious liability. Accordingly, the first inquiry is whether the defendant's wrongful act actually caused the damage, while the second concerns the extent to which the law regards that damage as sufficiently connected with the wrongful act to justify recovery.

It explained that factual causation is determined through the "but for" test, whereas legal causation depends upon the principle of reasonable foreseeability. The Court referred to The Wagon Mound and the Supreme Court's decision in Rajkot Municipal Corporation v. Manjulben Jayantilal Nakum to reiterate that foreseeability governs the issue of remoteness of damage.

The Bench explained that the dispute before it centred on the doctrine of novus actus interveniens, namely, whether a subsequent event had displaced the original wrongful act as the effective cause of the damage. Referring to Halsbury's Laws of India, the Court held that the mere existence of an intervening human act does not automatically sever liability.

The Court further observed: "The chain of causation may break when the third-party acts with unconstrained choice to commit the intervening act and the defendant is less likely to be liable. But if the act of the third party is lawful, generally damage will not result. If the act of the third party is wrongful, negligent or intentional, then it is less likely that the defendant will be liable and the damage will be considered remote and unrecoverable."

The Court also discussed the "eggshell skull rule", observing that a defendant takes the victim as found and cannot avoid liability merely because the claimant possesses an unusual physical or mental susceptibility that aggravates the consequences of the injury. It held that legal causation is determined by examining whether the original wrongdoing remained sufficiently connected with the damage, applying foreseeability together with the eggshell skull principle.

The Bench surveyed several authorities from England, Australia and the United States dealing with intervening acts, medical negligence and aggravated injury. Analysing decisions such as Smith v. Leech Brain, Robinson v. Post Office, Pigney v. Pointers Transport Services, Webb v. Barclays Bank, Looney v. Davis, and Jenkinson v. Hertfordshire County Council, the Court noted a consistent judicial approach that medical treatment required because of the original injury ordinarily remains a foreseeable consequence of that injury.

Consequently, it held that aggravation arising during such treatment generally does not break the chain of causation unless the subsequent medical intervention is so extraordinary or wholly inappropriate that it eclipses the original wrongdoing as the effective cause of the damage.

Applying the above principles, the Court held that there was no dispute that the injuries suffered by the deceased were the direct result of the motor accident. The real question was whether the subsequent medical complications and eventual death constituted an independent, unforeseeable intervening event sufficient to displace the original wrongful act as the effective cause of the damage. In answering that question, the Court found the medical evidence led by the claimants to be decisive.

The Court relied upon the testimony of the treating surgeon, who stated: “The cause of death of the patient is his suffering from ileal perforation peritonitis and septicemia which can be the result of the patients taking NSAIDS (group of medicines used as pain killers) which were given to the patient as a result of the accident in question.”

The witness further categorically stated: “It is wrong to suggest that death in this case, is not related to the accident in question in any manner.”

The Bench observed that this constituted the only relevant medical evidence on record and remained completely uncontroverted. Although the Insurance Company sought to attribute the death to other medical conditions, the Court found that the medical records themselves showed that the painkillers had been administered because of the fractures sustained in the accident. It accepted the medical expert's opinion that the medication would not have been prescribed but for the injuries suffered in the accident and that there was no evidence establishing any independent cause of death.

The Court further noted that the Insurance Company neither adduced any evidence before the Tribunal to rebut the medical testimony nor objected to the amendment converting the proceedings into a death claim. Even in appeal, it rested its challenge on legal principles rather than any contrary medical evidence. In those circumstances, the Tribunal's finding on causation, based on uncontroverted medical evidence, did not warrant interference.

Examining the factual chain of events, the Court observed that the deceased remained under continuous treatment following the accident and underwent repeated hospitalisation over several months. The administration of NSAIDs was found to be a normal component of treatment for fractures, and there was no evidence that the treating doctors had acted negligently or that the treatment was so extraordinary as to constitute a novus actus interveniens.

The Bench held: “There was no unwarranted or exceptional intervening act which would break the chain of causation. If there was some unusual susceptibility to NSAIDS, neither was it recorded by any hospital nor any evidence has been produced in that regard.”

The Court concluded that the original negligence continued to operate throughout the sequence of events. The injuries sustained in the accident necessitated prolonged medical treatment; the treatment involved the administration of ordinary pain medication, and the subsequent complications arose in the course of that treatment.

Since the medical treatment was itself a natural and foreseeable consequence of the original injuries, it could not be regarded as an independent cause displacing the liability of the original wrongdoer. The Court therefore held that the doctrine of novus actus interveniens had no application to the facts of the case.

The Bench also rejected the contention that the conclusion was founded merely upon the beneficial object of the Motor Vehicles Act. It clarified that the result flowed from the settled principles governing causation, foreseeability and remoteness of damage, holding that the appeal was devoid of merit.

Conclusion

The High Court upheld the Tribunal's finding that the victim's death remained causally connected to the injuries sustained in the motor accident and that the original wrongdoer continued to be liable notwithstanding complications arising during medical treatment.

Holding that there was no independent or extraordinary intervening event capable of breaking the chain of causation, the Court dismissed the appeal and directed the release of the balance compensation along with accrued interest in accordance with the Tribunal's award.
