Holding

Held that while the appellant's pump attendant was negligent in refuelling a petrol-powered vehicle with diesel fuel, the respondent failed to prove on a balance of probabilities that this negligence caused the subsequent engine breakdown. The court found that the respondent did not adduce evidence sufficient to eliminate other possible causes of the damage, particularly natural wear and tear on piston number three, as testified by the appellant's mechanic. Where it is equally probable that damage resulted from a cause for which the defendant was not responsible, the plaintiff cannot recover. The appeal was allowed, the trial court judgment set aside, and the suit dismissed.

Outcome

Suit dismissed with costs to the appellant

Facts

The respondent owned a Toyota Noah motor vehicle registration number UAM 357 Z which he operated as a commuter taxi. On 3 May 2017, the respondent's driver branched into the appellant's fuel station at Lacor to refuel with petrol but the pump attendant refuelled the vehicle with diesel instead. The vehicle stalled about 150 meters away. The appellant's mechanic drained the diesel, flushed the fuel system, replaced spark plugs, and refilled the tank with petrol. The driver conducted a road test and drove the vehicle away. Three days later, the respondent claimed the vehicle had developed mechanical problems including excessive smoke and loss of power, and eventually parked it at the appellant's fuel station demanding a complete engine overhaul. The respondent sued for damages claiming the refuelling mishap caused engine damage including an engine knock. The trial Magistrate found the appellant negligent and awarded shs. 13,000,000 special damages and shs. 7,000,000 general damages.

Issues

  1. Whether the appellant was negligent in refuelling the respondent's petrol-powered vehicle with diesel fuel.
  2. Whether the respondent proved on a balance of probabilities that the appellant's negligent act caused the engine damage claimed.
  3. Whether the trial Magistrate properly evaluated the evidence as to the cause of the vehicle's breakdown.
  4. Whether the awards of special and general damages were justified and within the trial court's pecuniary jurisdiction.

Orders

  • Appeal allowed.
  • Judgment of the court below set aside.

Rules and key headnotes

Negligence — Three-Part Test — Duty of Care, Breach, and Causation
Negligence is proved by satisfying a three-part test: the existence of a duty of care owed to the plaintiff by the defendant; a breach of that duty by falling below the appropriate standard of care; and damage caused by the defendant's breach of duty that is not too remote a consequence of the breach.
Negligence — Duty of Care — Foreseeability and Proximity
Where possible harm is foreseeable and there exists sufficient proximity between the defendant and the plaintiff such that in the reasonable contemplation of the former, carelessness on his part may be likely to cause damage to the latter, a duty of care exists.
Negligence — Standard of Care — The Reasonable Person Test
The standard of care in negligence is that of the reasonable person: negligence is the omission to do something which a reasonable person, guided upon those considerations which ordinarily regulate human affairs, would do, or doing something which a prudent and reasonable person would not do. The reasonable person only has to do what is reasonable to avoid risks of harm and there is no obligation to go to extraordinary lengths, particularly if the risk is slight.
Negligence — Pump Attendant's Duty — Dispensing Correct Fuel Type
A pump attendant has a duty to be proficient in the operation of dispensing equipment and capable of discerning the correct motor fuel for all types of vehicles requiring to be refilled. With safety measures including separate diesel dispensers, colour-coded handles, and differently sized nozzles designed to prevent fuel mixing, the burden of refuelling with the correct type of fuel lies with the pump attendant and not the customer.
Causation — But For Test — Balance of Probabilities
The defendant will only be liable in negligence if the plaintiff would not have suffered the damage but for the defendant's negligent act or omission. The plaintiff must prove causation on a balance of probabilities by adducing evidence tending to eliminate other possible causes of the damage so as to indicate that the negligence speaks is probably that of the defendant.
Causation — Multiple Possible Causes — Failure to Eliminate Alternatives
Where the facts proven show that there are several possible causes of the damage in issue, for one or more of which the defendant was not responsible, and it is a pure matter of guesswork where the greater probabilities lie, the plaintiff will not recover since he has failed to prove that the negligence of the defendant caused the damage. A court will not guess between two equally probable causes.
Weight of Evidence — Factual Allegations Distinguished from Conclusions
Courts treat differently allegations of fact made by a witness from conclusions drawn by the witness. A court is not bound to accept as true a conclusion couched as a factual allegation. It is open to the court to prefer the testimony of certain witnesses over others and to place more weight on some parts of the evidence than others, particularly where there is conflicting evidence.
