Key concepts in the case
Equitable recoupment
This is an equitable ‘self-help’ remedy that can be used by trustees to recover overpaid pension benefits by reducing or suspending future instalments of pension. It is how the trustees intended to recover Mr E’s overpaid benefits.
Repayment
Repayment is different to recoupment – it is where the overpaid beneficiary would repay the overpaid amount under the legal principles of unjust enrichment. Repayment was not applicable in this case.
Laches
Although a limitation defence is available in repayment cases, it does not apply to recoupment. However, the equitable doctrine of laches is applicable. It can act as a defence to an attempt to recoup overpaid benefits where the trustee knows about a benefit issue, has delayed, and it would be unconscionable to allow recovery. Some form of detrimental reliance is usually needed. Relevant factors include the length of the delay and what was done or not done during the applicable period.
Change of position
For change of position defence, the member must be able to demonstrate the following.
Good faith: The member must have acted in good faith and not have actual or ‘Nelsonian’ knowledge of the overpayment – that is knowing that they had been overpaid or being aware that this was a possibility but not clarifying the position.
Detriment and causation: The overpayment must have caused the member to detrimentally change their circumstances – usually, because they have spent money which they would not otherwise have done but for the overpayment (a causal link between the change of position and the overpayment is required).
Detriment can encompass modest improvements in lifestyle and a rise in the general standard of living. Broadly, the member must have spent the money, and this must be irreversible.
Estoppel by representation
A representation may mean that a party will be held to the representation made (they are ‘estopped’ from going back on it). Three tests must be satisfied.
- Test 1: There must be a clear representation (or promise) upon which it is reasonably foreseeable that the claimant will act.
- Test 2: The claimant must act and do so reasonably in reliance on the representation.
- Test 3: They must suffer detriment if the defendant is not held to the representation.
Estoppel by convention
If parties act on common assumption that a particular set of circumstances is true, a party will not be permitted to go back on that agreed assumption if it would be unfair to do so.
