This advice will address the two contractual issues Hunter faces with Pamodzi Hotel Ltd. The first issue concerns whether Hunter can legally enforce Pamodzi’s promise to pay an additional K100,000 for the completion of apartment buildings. The second issue is whether Hunter can recover the K30,000 balance from a separate debt, despite having accepted a part-payment of K20,000. This advice will be structured using the Issue, Rule, Application, and Conclusion (IRAC) method for each problem.
The Additional K100,000 for the Apartments
**Issue**
The central issue is whether Pamodzi’s promise to pay Hunter an extra K100,000 to finish the building work on time is legally binding. Pamodzi argues that Hunter provided no valid consideration for this extra payment, as he was already contractually obliged to complete the work by the 4th of May.
**Rule**
For a contract or a contractual variation to be enforceable, there must be consideration from both parties. Consideration is essentially the price one party pays for the other’s promise (Dunlop Pneumatic Tyre Co Ltd v Selfridge & Co Ltd [1915]). A long-standing rule of English contract law is that performance of an existing contractual duty owed to the other party is not good consideration for a new promise from that party (Stilk v Myrick (1809)). In that case, sailors were promised extra wages to sail a ship home after two crew members deserted, but the promise was held to be unenforceable as the remaining sailors were only doing what they were already contracted to do.
Applying this strict rule, Hunter’s promise to finish the building work by the 4th of May would not be good consideration for Pamodzi’s promise of an extra K100,000, as he was already bound by the original contract to do so.
However, the courts have developed an important exception to this rule. In Williams v Roffey Bros & Nicholls (Contractors) Ltd [1991], the Court of Appeal held that if a party promises to pay more for the performance of an existing duty, that promise can be binding if the promisor receives a ‘practical benefit’ or avoids a ‘disbenefit’. The court laid out a five-stage test for this principle to apply:
1. There is a contract for goods or services between A and B.
2. Before performance is complete, B has reason to doubt that A will be able to complete their obligations.
3. B promises A an additional payment to ensure completion on time.
4. As a result, B obtains a practical benefit or avoids a disbenefit.
5. B’s promise was not a result of economic duress or fraud by A.
If all these conditions are met, the performance of the existing duty can be considered good consideration.
**Application**
We can apply the test from Williams v Roffey Bros to Hunter’s situation.
1. There is a contract between Hunter (A) and Pamodzi (B) for Hunter to build apartments. This condition is met.
2. Pamodzi had reason to doubt Hunter would complete the work. Hunter explicitly told Pamodzi’s director that he was “unable to finish the building on the original contract price”. This condition is met.
3. Pamodzi promised an additional payment (doubling the price to K200,000) for Hunter to finish by the original deadline. This condition is also met.
4. Pamodzi obtained a practical benefit. The facts state that Pamodzi had “already let out the apartments to third parties” and feared “facing penalties on its other commitments”. By ensuring Hunter finished on time, Pamodzi avoided these financial penalties and secured the rental income from the apartments. This is a clear practical benefit, similar to how the main contractor in *Williams v Roffey Bros* avoided a penalty clause in their main contract.
5. The final question is whether Hunter exerted economic duress. Economic duress occurs where one party uses illegitimate pressure to force the other into a contract or variation. A threat to breach a contract can be illegitimate pressure. Here, Hunter stated he was unable to finish, which put Pamodzi in a difficult position. Pamodzi agreed because it feared the consequences of late completion. This could be seen as duress. However, Hunter’s statement was that he would be unable to make a profit and therefore could not finish. This might be interpreted not as a bad faith threat, but as a genuine notification of his financial difficulties. If Pamodzi, as a commercial party, then chose to offer more money to secure its own commercial interests, a court might find that the promise was a pragmatic commercial decision rather than the result of illegitimate pressure. The fact that Hunter did not demand the money but simply stated his position might weigh in his favour.
**Conclusion**
Hunter has a strong argument that Pamodzi’s promise to pay the extra K100,000 is legally enforceable. He can rely on the doctrine of practical benefit established in Williams v Roffey Bros. The main risk to his claim is the argument of economic duress. If a court views his statement as a legitimate warning of impending non-performance due to financial hardship, he will likely succeed. If it is viewed as an illegitimate threat to breach the contract, the promise will be voidable, and he will not be able to recover the extra money. On balance, his claim appears to have a good chance of success.
The K30,000 Outstanding Debt
**Issue**
The issue here is whether Hunter can recover the remaining K30,000 of a K50,000 debt after he accepted a payment of K20,000. Pamodzi argues that Hunter is prevented from recovering the balance by the doctrine of promissory estoppel.
**Rule**
The common law rule, established in Pinnel’s Case (1602) and affirmed by the House of Lords in Foakes v Beer (1884), is that part-payment of a debt is not good consideration for a promise to discharge the entire debt. A creditor is therefore generally able to go back on a promise to accept a lesser amount and can sue for the full balance. The courts have explicitly refused to extend the ‘practical benefit’ principle from *Williams v Roffey Bros* to cases of part-payment of debt (Re Selectmove Ltd [1995]). At common law, Pamodzi’s payment of K20,000 is not sufficient consideration for Hunter’s promise (if he made one) to forget the remaining K30,000.
However, Pamodzi may be able to use the equitable doctrine of promissory estoppel as a defence. This doctrine, explained in Central London Property Trust v High Trees House [1947], can stop a promisor from going back on a clear promise to waive their legal rights where it would be inequitable to do so. For promissory estoppel to apply:
1. There must be a pre-existing legal relationship between the parties.
2. There must be a clear and unambiguous promise by the creditor that they will not enforce their strict legal rights.
3. The debtor must have relied on that promise.
4. It must be inequitable (unfair) for the creditor to go back on their promise.
Promissory estoppel acts as a ‘shield, not a sword’, meaning it can only be used as a defence to a claim, not to start one. Here, Pamodzi would use it as a defence against Hunter’s claim for the K30,000.
**Application**
At common law, under the rule in Foakes v Beer, Hunter is entitled to the full K50,000. The payment of K20,000 does not discharge the debt. Hunter can therefore sue for the remaining K30,000.
Pamodzi’s only defence is promissory estoppel. We must analyse if the conditions are met.
1. There is a pre-existing legal relationship (the contract for the “other buildings”).
2. There may not be a clear promise from Hunter. He said “let me have the 20,000 and you can later pay me the full amount”. This was an attempt to reserve his rights. Pamodzi rejected this with a “take it or leave it” ultimatum. Hunter’s subsequent act of taking the money could be seen as an implied acceptance of their terms, but this is arguable.
3. Hunter relied on the situation by taking the lesser sum.
4. The most important point is whether it would be inequitable for Hunter to demand the rest of the money. Equity requires those who seek its assistance to have acted fairly themselves (‘clean hands’). In D & C Builders v Rees [1966], a debtor knew the builders were in financial trouble and offered a smaller sum in full settlement, telling them it was that or nothing. The builders reluctantly accepted. The Court of Appeal held that the debtor could not rely on promissory estoppel because they had not acted equitably; they had taken advantage of the creditor’s financial situation.
The facts here are very similar to D & C Builders. Pamodzi knew Hunter needed money for “more building commitments” and to “purchase material”. They issued an ultimatum: “take it or leave it, we will never have enough to pay you”. This is not a freely negotiated agreement but rather pressure applied to a creditor in a vulnerable position. Because Pamodzi’s conduct was inequitable, a court is highly unlikely to allow them to use the equitable defence of promissory estoppel.
**Conclusion**
Hunter has a very strong claim to recover the outstanding K30,000. The common law rule in Foakes v Beer is clear that the part-payment did not discharge the full debt. Pamodzi’s likely defence of promissory estoppel will almost certainly fail because their conduct in pressuring Hunter to accept the lesser sum was inequitable, following the precedent set in D & C Builders v Rees. Hunter should be advised that he can successfully sue for the balance.
