Langkawi Yacht Club Bhd v Suzannah Helen Harvey & Anor

Appellant(s): Langkawi Yacht Club Bhd

Respondent(s):

• Suzannah Helen Harvey
• Ronan Francis Harvey

• YA Datuk Azimah binti Omar
• YA Datuk Wong Kian Kheong
• YA Datuk Ismail Bin Brahim

• The respondents initiated an action against the appellant, a yacht club operator, alleging that contaminated diesel supplied by the appellant caused engine damage to their vessel during a voyage from Langkawi to the Maldives.
• The High Court allowed the claim and awarded damages for repair costs, loss of use, and mental distress, primarily relying on the temporal proximity between the refueling and the engine failure despite a lack of direct evidence of contamination.
• Evidence at trial revealed that the respondents failed to maintain objective bunkering logs, mixed the appellant's fuel with diesel from other sources, and could not account for a significant "phantom" excess of fuel found in their own calculations.

• Whether the High Court erroneously reversed the legal burden of proof by requiring the appellant to prove an alternative cause of damage before the respondents had discharged their primary burden of proving the appellant’s fuel was the *causa causans*.
• Whether the High Court erred in admitting and preferring the opinion evidence of a witness of fact on scientific matters (hydrodynamics and fuel chemistry) without the witness being qualified or tendered as an expert under Order 40A of the Rules of Court 2012.
• Whether the High Court failed to properly appreciate contemporaneous documentary evidence and independent witness testimonies which contradicted the respondents’ self-serving and "backwards-engineered" recollections.

• The Court allowed the appeal and set aside the High Court’s decision, ruling that the legal burden of proof remains on the plaintiff throughout and cannot be discharged by merely pointing to the perceived weaknesses of the defense.
• The Court held that the High Court committed a grave error by admitting expert opinions from the second respondent, a plain witness of fact, in breach of the mandatory procedures for expert evidence, especially when his "theories" were debunked by the respondents' own actual expert chemist.
• The Court found the respondents’ case unreliable due to a broken chain of custody regarding fuel samples and the fact that fuel tests showed the appellant’s storage tanks were not contaminated, suggesting any ingress occurred while the fuel was under the respondents' sole control.
