Intention to create legal relations; consideration and causa

Parties must intend legal consequences. English law also needs consideration, but Sri Lanka's Roman-Dutch law accepts causa: a serious and deliberate reason for the promise.

Domestic agreementsPresumed not binding (Balfour v Balfour, 1919)
Commercial agreementsPresumed binding unless clearly excluded
ConsiderationSomething of value given in return (Currie v Misa, 1875)
Causa in Sri LankaWider than consideration (Jayawickreme v Amarasuriya, Privy Council, 1918)

Intention to create legal relations

An agreement becomes a contract only if the parties intend it to have legal consequences. Courts start from two presumptions. In social and domestic agreements, the presumption is that there is no such intention: in Balfour v Balfour, a husband's promise to pay his wife a monthly allowance while he worked in Ceylon (as Sri Lanka was then called) could not be enforced. In commercial agreements, the presumption is that the parties do intend to be bound. It can be rebutted only by clear words, as in Rose and Frank Co v Crompton Bros, where the written agreement said it was an honourable pledge and not a legal agreement.

Consideration in English law

RuleMeaningExample
DefinitionSome right, benefit or profit to one party, or some loss or detriment to the other (Currie v Misa)Paying Rs. 50,000 for a laptop
Must move from the promiseeThe person enforcing the promise must have given somethingA stranger to the bargain cannot sue on it
Need not be adequateThe court does not judge whether the bargain was fairSelling a car for Rs. 1,000 is still valid
Must be sufficientIt must have some value in the eyes of the lawA real act, payment or promise
Past consideration is no considerationSomething done before the promise does not count (Re McArdle)Paying for repairs already finished, without an earlier request
Existing duty is not enoughDoing what you are already bound to do is not consideration (Stilk v Myrick)Sailors promised extra pay for doing their contracted work

Causa in Roman-Dutch law

Sri Lanka's general law of contract is Roman-Dutch law, and it does not require consideration. A promise is enforceable if it is made seriously and deliberately, with the intention of being legally bound. This ground or reason is called causa (justa causa, a lawful cause). There need be nothing given in return, so a seriously made promise of a gift can be binding. In Jayawickreme v Amarasuriya (1918), the Privy Council enforced a brother's promise to pay his sister money to settle a family property claim. It held that under the Roman-Dutch law of Ceylon, causa is far wider than English consideration: a promise deliberately made to discharge a moral duty, or out of generosity, can be enforced. Where English law governs a matter through statute, consideration still matters: for example, a bill of exchange needs value.

Consideration and causa compared

PointConsideration (English law)Causa (Roman-Dutch law)
BasisA bargain: something given in returnA serious and deliberate intention to be bound
Promise of a giftNot enforceable (unless made by deed)Enforceable if made seriously and deliberately
Where it applies in Sri LankaMatters governed by English law, e.g. bills of exchangeGeneral contracts governed by Roman-Dutch law
Leading caseCurrie v MisaJayawickreme v Amarasuriya
In Sri Lankan business

If the owner of a hardware business in Kandy seriously promises in writing to donate Rs. 500,000 to a school building fund, Roman-Dutch causa may make the promise enforceable, even though he receives nothing in return. Under English law, the same promise would fail for want of consideration.

Exam angle

Short answer: “What is meant by causa?” In Roman-Dutch law, the serious and deliberate reason or intention behind a promise, which makes it enforceable without consideration.

Structured question: “Explain intention to create legal relations with decided cases.” Domestic agreements presumed not binding (Balfour v Balfour); commercial agreements presumed binding, rebuttable by clear words (Rose and Frank v Crompton).

Essay: “Compare the English doctrine of consideration with the Roman-Dutch doctrine of causa as applied in Sri Lanka.” Define both; give the rules of consideration with cases; explain causa and Jayawickreme v Amarasuriya; compare in a table; show where each applies in Sri Lanka.

Remember it

English law asks 'What did you get in return?' (consideration). Roman-Dutch law asks 'Did you mean it seriously?' (causa).
