QUESTION 1
Discuss in general (without reference to a specific enrichment action) how the
extent of enrichment liability (or the quantum of the enrichment claim) will be
calculated.
(15 marks)
The calculation of the extent of enrichment liability, or the quantum of the enrichment
claim, plays a critical role in unjustified enrichment actions. It ensures that a balance is
struck between the unjustified gain of the enriched party and the loss of the
impoverished party, without leading to overcompensation or penal consequences.
1. General Principle
In principle, a claim for unjustified enrichment is limited to the lesser of two amounts:
The amount by which the defendant (enriched party) has been enriched; or
The amount by which the plaintiff (impoverished party) has been impoverished.
This is known as the “double ceiling” rule. The claimant cannot recover more than
their own loss or more than the defendant’s gain.
, 2. Determination of Enrichment
The enrichment is usually determined by assessing the increase in the defendant’s
estate. This can include:
Acquisition of property or money
Discharge of debts
Improvement of property
Provision of services
The enrichment must be actual and measurable, not hypothetical or speculative.
3. Time of Assessment
The enrichment is assessed at the time the legal action is instituted, not necessarily
at the time of the enrichment. However, if the enrichment has ceased through no fault
of the enriched party, there may be no liability unless the enrichment was retained
long enough to create a lasting benefit.
4. Impoverishment
Impoverishment refers to a patrimonial loss suffered by the plaintiff. It must be clear
and quantifiable. For example, if a person pays another’s debt by mistake, they have
suffered a financial loss equal to the payment.
5. Benefits that Have Been Consumed or Lost
If the enriched party has lost the benefit (e.g. spent the money or consumed goods)
and cannot return it, liability will generally not arise unless the benefit was lost through
fault, or the enriched party retained it for an unreasonably long time. This is governed
by the defence of loss of enrichment.
