Study Notes on Unjustified Enrichment

Professor Mark Godfrey
Lecture 29: Focus on Unjustified Enrichment 5 covering:
  - Enrichment by Imposition
  - Enrichment by Taking
  - Defence mechanisms against unjust enrichment

Excursions on Transfer:
  - Transfer is just one method through which unjustified enrichment can occur.
  - Key recategorization of pre-Shilliday law is as follows:
    - Restitution: Return of a fixed thing.
    - Repetition: Return of a fixed sum of money, synonymous with the term TRANSFER.
    - Recompense: Return of the value of an unquantified benefit, determined by the degree to which it enriched the beneficiary, termed quantum lucratus est, encompassing IMPOSITION and TAKING.

Unauthorised Improvement to Another’s Property - classification as IMPOSITION.
Performance of Another’s Obligation - also regarded as IMPOSITION.
Unauthorised Use of Another’s Property - categorized as TAKING/INTERFERENCE.

Criteria for Unjustified Enrichment:
  - Enrichment of the true owner must be due to unauthorized improvements.
  - The improver must possess the property in good faith.
  - There must be an error on part of the improver, believing themselves to be the omner, indicating a non-transitory imposition of benefit.

Initial Events:
  - Feb 1919: Mr. Newton purchases a house with the title in fiancée’s name.
  - 1919: Mr. Newton finances improvements on the house.
  - April 1920: Mr. and Mrs. Newton marry.
  - May 1920: Mr. Newton demands the title be conveyed to him, but Mrs. Newton refuses, prompting litigation.
Court Proceedings:
- Jan 1923: Court rules Mrs. Newton as the owner.
- June 1923: Mr. Newton seeks recovery of the improvements value.
Legal Question: Can Mr. Newton reclaim the value of improvements under a mistaken belief the house was his?

LJC Alness's Insight:
  - The test for good faith possession does not hinge on the title but rather on the bona fides of the claimant.
  - Mr. Newton previously held a mistaken yet clear belief that he was the rightful owner of the property.
  - Benefits conferred upon the property by Mr. Newton derive from expenditures made due to this mistaken belief.

Mistaken belief of ownership crucial for determining unjustified enrichment.
Focus is on the mental state of the pursuer regarding ownership rather than factual ownership.

Example Fact Situation:
- D owes a debt to T; P discharges this debt.
Claim Result:
- When P pays D’s debt to T, D becomes enriched if T acknowledges the full discharge of the obligation.

Parties Involved:
- Bank of Scotland → Ruthven (debtor) ← Kirk (debtor & guarantor) ← Reid (third party guarantor).
Scenario:
- The Bank collects from Kirk, who owes debts, subsequently settling Reid’s obligations due to Kirk’s estate posthumously.
- Query: Can Reid claim a refund directly from Ruthven or must he pursue Kirk’s estate solely?

Lord Anderson’s Clarification:
- In Scots law, a debt obligation is discharged if paid by another with creditor's consent, regardless of the payer's identity.
- Reid possesses legal rights for money paid towards a third-party debt due to the nature of discharge.

Determining Unjustified Enrichment Through Taking:
- Must involve unauthorized use of property rights.
- Valuation by “just and reasonable consideration” given the hypothetical bargain value.

Background:
- Lease regarding the estate shooting rights contested due to change in ownership.
Court decision mandated recompense due to unjustified benefits enjoyed during contested occupancy.

Key case for reference: Credit Lyonnais v George Stevenson & Co. Ltd (1901).
Circumstances involve erroneous bank remittance due to confusion of names.

Incident:
- Bank inadvertently paid money meant for one company into another with a similar name.
- Recipient assumed the payment to offset debts leading to later claims of change in position after a discovery lapse of 11 months.

G Stevenson rationalized the erroneous payment believing it to be legitimate, resulting in negative financial implications.

Change of position viable under three conditions:
  1. Reasonable belief the benefit belonged to them.
  2. Actions taken based on that belief.
  3. Position is materially worse, rendering reversal of the enrichment unjust.

Findings:
  - Reasonable grounds for belief? NO. Good faith handling? YES.
  - Decision disallowed the defence of change of position due to lack of specific adverse actions tied to the mistaken payment.
  - Result: Credit Lyonnais awarded recovery for the erroneous payment.

Lord Rodger's Declaration in Shilliday v Smith:
- Remedies such as repetition, restitution, reduction, and recompense are instruments courts utilize to rectify unjust enrichment, with their applicability influenced by the enrichment type and situation's complexity, necessitating tailored legal recourse to address the enrichment.
