With unfairness, the elements really are whether it causes a significant imbalance in rights and obligations of the parties and whether it isn't reasonably necessary to protect the interests of the benefiting party and whether it would cause detriment. So that is a robust test. It is a clear test on fairness. It is based on the effects on the parties, and it can lead to the Commerce Commission declaration so that a term may not apply. To my mind, that is an equitable approach; it is about equity and it is about fairness.
