Factual and Procedural Background
On 6 November 1995 the Plaintiff was driving his motor car on a public road near The City in The State. He alleged that a patch of oil on the carriageway caused him to lose control of his vehicle and collide with an on-coming car. The Statement of Claim asserted that the oil had been spilled by an unidentified motor vehicle whose owner or user remained untraced.
The Defendant was sued under an agreement dated 21 December 1988 between the Minister for the Environment and the Defendant (“the MIBI Agreement”). In the High Court, the trial judge accepted expert evidence that the spill most likely came from a lorry or truck with a missing, defective, or improperly fitted fuel-tank cap, but held that the spill could have occurred with or without negligence. Despite that finding, the High Court held the Defendant liable, reasoning that the purpose of the MIBI Agreement was to ensure compensation where no insured driver could be identified.
The Defendant appealed to the Supreme Court. On 24 February 2003, Judge Hardiman (with Judges Murray and Geoghegan concurring) delivered judgment.
Legal Issues Presented
- Whether, under Clause 6 of the MIBI Agreement, a plaintiff must prove negligence in the driving of an unidentified vehicle before the Defendant can be held liable.
- Whether the doctrine of res ipsa loquitur or any shifting of the burden of proof relieved the Plaintiff from establishing negligence.
- Whether European Union directives require compensation for damage caused by an unidentified vehicle irrespective of proof of negligence.
Arguments of the Parties
Plaintiff's Arguments
- The unexplained fuel spill should invoke res ipsa loquitur, shifting the burden to the Defendant to disprove negligence.
- Alternatively, under the relevant EU Directive, compensation is due for injury caused by an unidentified vehicle without the need to prove negligence, and the MIBI is an emanation of the State bound by that obligation.
Defendant's Arguments
- Negligence is a condition precedent to liability under Clause 6; the Plaintiff bears the burden of proof and failed to discharge it.
- Res ipsa loquitur does not apply because the evidence shows the spill could have occurred without negligence and is not peculiarly within the Defendant’s knowledge.
- The EU Directive argument was not pleaded at trial and, in any event, does not eliminate the requirement to prove negligence.

Court's Reasoning and Analysis
1. Requirement of Proved Negligence. Clause 6 of the MIBI Agreement expressly conditions liability on “negligent driving” by an unidentified motorist. The Court held that this contractual prerequisite cannot be ignored.
2. Findings of Fact Do Not Establish Negligence. The High Court had found that the spill could have occurred either with or without negligence. Accepting those findings, the Supreme Court concluded that negligence remained unproven.
3. No Shift in the Burden of Proof. Drawing on Hanrahan, the Court stated that the evidential burden shifts only where the relevant facts lie peculiarly within the defendant’s knowledge. Here, neither party knew how the spill occurred; therefore, the burden stayed with the Plaintiff.
4. Limits of res ipsa loquitur. Reviewing Byrne and Scott, the Court emphasised that the doctrine applies only when an accident is of a kind that ordinarily does not happen without negligence. The possibility of a non-negligent spill prevented its application.
5. EU Directive Argument Rejected. The alternative submission—that EU law provides a strict-liability right to compensation—had not been pleaded below and, if accepted, would create an anomalous preference for claims against unidentified drivers. The Court therefore declined to entertain it.
6. No Policy-Based Expansion of Liability. Judge Hardiman disagreed with the High Court’s view that denying recovery would defeat the Agreement’s purpose. The contractual text, not broader policy considerations, governed liability.
Holding and Implications
Appeal allowed; the Plaintiff’s claim is dismissed.
The decision confirms that, under the MIBI Agreement, a claimant must prove negligent driving by an unidentified motorist; mere proof of an unidentified vehicle’s involvement is insufficient. The ruling also delineates the narrow scope of res ipsa loquitur and affirms that the burden of proving negligence remains with the plaintiff unless the factual circumstances squarely justify shifting it. No new precedent was set, but the judgment provides clear guidance for future claims against the Motor Insurers’ Bureau.
