Lee Castleton v Post Office Limited & Anor

Lee Castleton v Post Office Limited & Anor

The court held that the hybrid approach of assuming POL's knowledge of viable claims for the purposes of the preliminary issues trial, while requiring factual findings on other elements of unconscionability, creates significant practical difficulties and risks inefficiency and unfairness. Therefore, the order for the preliminary issues trial in its current form cannot stand and must be revisited.

Procedural Posture

Civil Appeal / Appeal From High Court Directions Order

Legal Issues

  1. 1 Whether the court erred in adopting a hybrid approach to the trial of preliminary issues by assuming some facts and requiring findings on others

  3. 3 Whether the preliminary issues trial can fairly and efficiently determine the unconscionability issue based on provisional assumptions

Ratio Decidendi

The court held that the hybrid approach of assuming POL's knowledge of viable claims for the purposes of the preliminary issues trial, while requiring factual findings on other elements of unconscionability, creates significant practical difficulties and risks inefficiency and unfairness.
