Sutton and East Surrey Water Plc v Monarch Chemicals Limited & Anor

Summary

After a chemical incident at a water treatment works, a chemical supplier settled the water company's claim for just over 5.6 million pounds and then sought a contribution from the haulier that had delivered the chemicals. The main claim settled shortly before trial, and the trial continued only on the contribution claim.

The supplier said the haulier shared responsibility for the incident and should contribute. The haulier said it owed the water company no duty, was not liable for the same damage, and in any event was protected by its standard conditions of carriage.

Adrian Williamson KC dismissed the contribution claim. The haulier owed the water company no duty of care in tort, was not vicariously liable for the driver, and was not liable in respect of the same damage. Even if it had been, its standard conditions of carriage excluded, limited or time-barred the claim.

Background and facts

On 2 February 2017 an incident occurred at Sutton and East Surrey Water's Elmer Water Treatment Works at Leatherhead in Surrey. A delivery vehicle was carrying more than one chemical, including ferric sulphate and a sodium hypochlorite mixture. The driver connected and pumped over the wrong drum, the chemicals reacted, and a chlorine gas cloud was released. The driver was employed by the haulier, Muztrans, but had been seconded to the supplier, Monarch, under a long-term arrangement.

The water company brought a substantial claim for its losses. The chemical supplier, Monarch Chemicals, settled that claim shortly before trial by paying just over 5.6 million pounds, and the water company discontinued its claim against the haulier, Muztrans.

The trial then continued on Monarch's Part 20 claim for a contribution from Muztrans. The factual evidence was limited, and the water company's own witnesses were not called, so the issues were largely ones of law.

The issue

The central question was whether Monarch could recover a contribution from Muztrans under the Civil Liability (Contribution) Act 1978. That required Muztrans to be liable to the water company in respect of the same damage as Monarch.

If Muztrans was so liable, the further question was whether any liability was excluded, limited or time-barred by the contract between Monarch and Muztrans and by the standard road haulage conditions.

The decision

Adrian Williamson KC dismissed the contribution claim. Contribution under the 1978 Act depends on the party from whom it is sought being liable to the injured party for the same damage. Muztrans was not.

"Muztrans did not owe SESW a duty of care in tort."Adrian Williamson KC, paragraph 86

Because the driver was Muztrans's employee seconded to Monarch, the haulier could be liable at all only on the principle of dual vicarious liability, where two parties share vicarious responsibility for the same employee. The judge held there was no dual vicarious liability here. The supplier had day-to-day operational control of the delivery, so the haulier was not vicariously liable for the driver jointly with the supplier, and it followed that it was not liable to the water company for the same damage:

"Muztrans is not liable to SESW in respect of 'the same damage' as Monarch."Adrian Williamson KC, paragraph 86

That was enough to defeat the contribution claim. The judge went on to hold that, even if there had been a liability to contribute, it was excluded, limited or time-barred by the contract between Monarch and Muztrans and by conditions 9, 11, 12 and 13 of the standard road haulage conditions of carriage. Those conditions had been fully incorporated into the contract and were reasonable within the meaning of the Unfair Contract Terms Act 1977.

The judge also found substantial contributory fault on the part of the water company itself, whose own procedures for the delivery were criticised in the contemporaneous investigations. Had contribution been due, he would have placed the lion's share on the supplier, given its day-to-day direction of the driver, leaving the haulier with only a small share of the responsibility.

Practical implications

A contribution claim is not a free-standing right to share a settlement. Under the 1978 Act it depends on the party you pursue being liable to the original claimant for the same damage. If that party owed the claimant no duty, or is not liable for the same loss, there is nothing to contribute to, however much the paying party feels the burden should be shared.

A carrier or haulier usually owes no duty of care in tort to the customer at the end of the supply chain for a delivery gone wrong. Vicarious liability for the driver turns on who engaged and directed the driver, and a party that controlled the delivery on the ground may carry the responsibility that it hoped to pass on.

Standard conditions of carriage do real work. The road haulage conditions of carriage, where properly incorporated, exclude, limit and time-bar a carrier's liability, and the court found them reasonable under the Unfair Contract Terms Act 1977. A party contracting with a haulier on those terms should assume that its recourse against the haulier is narrow and short-lived, and price and insure accordingly.

Settling the main claim does not settle contribution. A defendant that pays to settle should think about its contribution position before it does so, including whether the target is actually liable to the claimant, whether contractual conditions bar the claim, and what apportionment a court would reach. A generous settlement does not translate into a matching recovery from a co-defendant.
