A good relevant case is Ringrow Pty Ltd v BP Australia Pty Ltd (2005) 222 ALR 306. Ringeow and BP entered an agreement in 2005 to purchase a service station. The agreement required Ringrow to purchase fuel only from BP and allowed BP to buy the service station in case of reach of the agreement. After some time Ringrow decided to buy fuel from another supplier therefore, BP tried to use their option of the agreement. Thus, Ringrow claimed that BPs action was a penalty and therefore enforceable and void.
As a result, the court held that liquidated damages can be valid except if the amount was ‘out of proportion’ with the loss suffered. Also, the court decided that there must be an extravagant or unconscionable difference between the general damages and liquidated damages. The court decided there must be an extravagant or unconscionable alteration between the general damages and the liquidated damages. The difference would have been in the agreement to be paid on breach therefore to make a degree of disproportion that points to oppressiveness amounting to a penalty. The argument that was to terminate the contract for minor breaches was denied and did not reach the penalty
