Triple riding alone does not establish contributory negligence absent proof that it caused the accident.

On 30 June 2015, Mathankumar was riding a motorcycle bearing Registration No. TN-48-AX-1081 on the Trichy–Salem Main Road, with Nagarajan and Muruganandam as pillion riders. Near Padhanithoppu, a lorry bearing Registration No. TDY-5297 allegedly struck the motorcycle from behind due to the rash and negligent driving of its driver. Mathankumar and Nagarajan sustained grievous injuries, while Muruganandam died in the accident.

The driver and owner of the lorry remained ex parte before the Claims Tribunal. The insurer disputed the manner of accident, negligence, liability and quantum, contending, inter alia, that three persons were travelling on the motorcycle, that the motorcycle rider lacked a valid driving licence, and that the alleged overloading contributed to the accident.

The Motor Accidents Claims Tribunal awarded Rs.15,73,000 to the legal heirs of Muruganandam in MCOP No.1279 of 2015, Rs.5,01,900 to injured claimant Nagarajan in MCOP No.1311 of 2015, and Rs.27,14,295 to injured claimant Mathankumar in MCOP No.242 of 2018.

The insurer filed CMA Nos.884/2018, 885/2018 and 301/2021 challenging liability and quantum, while the claimants filed CMA No.1520/2021 and Cross-Objections Nos.22/2020 and 67/2026 seeking enhancement.

Whether the fact that three persons were travelling on the motorcycle established contributory negligence or otherwise exonerated the insurer from liability, in the absence of evidence that such overloading caused or materially contributed to the accident?

Whether the finding that the lorry driver alone was negligent was supported by the evidence and the police final report?

Whether the compensation awarded to Mathankumar for permanent disability and loss of future earning capacity required enhancement?

Whether the compensation awarded to the legal heirs of Muruganandam required enhancement on account of his income, future prospects and conventional heads?

Whether Nagarajan’s compensation required enhancement by reassessing his income, functional disability and loss of earning capacity?

The Court exercised appellate jurisdiction under Section 173 of the Motor Vehicles Act, 1988 over the awards of the Motor Accidents Claims Tribunal.

The mere presence of three persons on a two-wheeler does not, by itself, establish contributory negligence; the insurer must prove by cogent evidence that the violation materially contributed to the accident.

Negligence must be determined on the evidence as a whole, including the claimant’s testimony and the police final report, and cannot be inferred solely from a policy or traffic violation.

For computation of compensation, the Court applied the multiplier method, assessed functional disability according to the claimant’s actual impairment and occupation, and added future prospects where appropriate.

It also relied on National Insurance Co. Ltd. v. Pranay Sethi, AIR 2017 SC 5157; (2017) 16 SCC 680, particularly for future prospects and conventional heads such as consortium and funeral expenses.

The Court upheld the finding that the lorry driver was solely negligent because Mathankumar’s evidence, the absence of contrary evidence from the insurer, and the final report in Crime No.205 of 2015 supported the case that the lorry struck the motorcycle from behind.

Although three persons were travelling on the motorcycle, the insurer did not establish that the additional passenger materially affected the motorcycle’s stability or caused the collision. Accordingly, no contributory negligence could be imposed merely on the basis of the number of occupants.

For Mathankumar, aged 22 and holding a Diploma in Mechanical Engineering, the Court found the Tribunal’s notional income of Rs.10,000 per month inadequate. It fixed the income at Rs.15,000 per month, added 40% towards future prospects, applied a multiplier of 18, and treated the disability as 100% functional disability because the amputation of his right arm prevented him from continuing as a mechanic.

His loss of future earning capacity was therefore enhanced from Rs.20,40,000 to Rs.45,36,000, resulting in total compensation of Rs.52,10,295.

For Muruganandam, aged 35 and working as a carpenter, the Court fixed the monthly income at Rs.10,000, added 40% towards future prospects, applied a multiplier of 16, and deducted one-third towards personal expenses. It calculated loss of income at Rs.17,92,000.

Applying Pranay Sethi, it revised the amounts for consortium, loss of love and affection, and funeral expenses, fixing the total compensation at Rs.19,27,000.

For Nagarajan, an agricultural coolie aged 38, the Court reassessed the income at Rs.10,000 per month, added 25% towards future prospects, applied a multiplier of 15, and reduced the functional disability from 35% to 25%, considering the nature of his injuries and treatment.

His loss of earning capacity was calculated at Rs.16,87,500, and the total compensation was enhanced to Rs.17,79,947.

CMA No.1520/2021 filed by Mathankumar was partly allowed, and Cross-Objections Nos.22/2020 and 67/2026 were allowed.

The compensation was modified as follows: Rs.52,10,295 to Mathankumar, Rs.19,27,000 to the legal heirs of Muruganandam, and Rs.17,79,947 to Nagarajan, in each case with interest at 7.5% per annum from the date of petition until deposit.

The insurer was directed to deposit the amounts within twelve weeks, subject to adjustment of any amount already deposited. The claimants were directed to pay the deficit court fee and could thereafter withdraw the amounts with accrued interest in accordance with the Tribunal’s apportionment orders.
