Acceptance of Offers Under Contract Law in Ghana: Rules, Methods, and Legal Effects

1. Meaning and Nature of Acceptance

Acceptance is the clear and final assent by the offeree to all the terms of an offer. It converts a mere offer into a legally binding agreement once the other elements of contract formation such as consideration and intention to create legal relations are present.

Under Ghanaian contract law, which draws heavily from English common law principles and statutory interventions such as the Contracts Act, 1960 (Act 25) and the Electronic Transactions Act, 2008 (Act 772), acceptance must be objective, certain, and unequivocal.

Key Features of Acceptance

1. It must correspond exactly with the terms of the offer.
2. It must be unconditional and unqualified.
3. It must be communicated to the offeror unless communication has been expressly or impliedly waived.
4. It may be expressed by words, writing, or conduct.

Ghana Home Loans Ltd v First Ghana Savings & Loans

Facts

The plaintiffs sought to acquire a controlling stake in the Defendant. Plaintiff made an offer which the defendant’s board accepted. The defendant allegedly resiled from the contract. The plaintiffs thus sued claiming a breach of contract. Thereby seeking damages or specific performance. 

Court Reasoning

The court had to determine whether there existed a binding contract between the parties. The defendants alleged that there was no acceptance as acceptance was subject to the approval of shareholders and the Bank of Ghana. The court held that the Turquand rule allows third parties to assume that internal company approvals have been obtained when dealing with the directors of a company. Regulatory approvals do not negate the existence of a binding contract. 

Holding

There was a binding contract when the Board accepted the Plaintiff’s offer. 

2. Forms of Acceptance

(a) Acceptance by Words

Acceptance may be communicated orally or in writing. This includes letters, emails, signed agreements, or verbal statements.

Illustration
A offers to sell a laptop to B for GHS 5,000. B replies by letter or WhatsApp stating “I accept your offer at GHS 5,000.” A valid acceptance has occurred.

(b) Acceptance by Conduct

Acceptance may also be inferred from the conduct of the offeree where the conduct objectively shows assent to the offer.

Brogden v Metropolitan Railway Company

Facts Explained 

Brogden supplied coal to the Metropolitan Railway Company for several years without a formal written contract. The parties later negotiated terms and drafted a written agreement. Brogden signed the document and sent it to the railway company. The company did not sign the document but placed it in a drawer. Despite the absence of a signature, both parties continued trading coal strictly according to the new written terms.

Decision and Reasoning

The court held that a binding contract existed. Although the railway company did not formally sign the agreement, their continued performance of the contract under the agreed terms amounted to acceptance by conduct.

Legal Principle

Where parties act in a manner consistent with the terms of an offer, the law may infer acceptance from their conduct.

Illustration
A landlord sends tenancy terms to a tenant. The tenant moves in, pays rent, and occupies the premises under those terms. Even without signing, acceptance may be inferred from conduct.

Thomas Akyea v Abii National Savings and Loans

The matter arose concerning a loan facility obtained by the plaintiff from the defendant. Plaintiff proposed to pay a certain sum as full settlement, enclosing a cheque with instructions to cash it only if the proposal was accepted. Defendant cashed the cheque but subsequently rejected the proposal, demanding full repayment of the debt. The plaintiff alleged that the cheque constituted acceptance. The defendant was therefore estopped from making further demands. The defendant counterclaimed for the full debt. 

Court Reasoning

The court found on evidence that the defendant cashed the cheque but communicated to the plaintiff that it had rejected the proposal and was thus cashing the cheque in fulfilment of the plaintiff’s debt liability. 

For an acceptance to be binding, it must be clear and unambiguous, unconditional and unqualified. The defendant’s conduct could have amounted to an acceptance had he not clearly communicated to the plaintiff that he did not accept the proposal. 

Holding

There had been no acceptance. 

(c) Acceptance in Writing

Written acceptance is common in commercial and land transactions. It is particularly important where proof of acceptance is required.

Fofie v Zanyo

Facts Explained

There was a dispute as to whether a transaction involved the sale of a building or merely a lease. The plaintiff claimed that he accepted an offer to purchase the building. The defendant argued that no sale contract existed and that the arrangement was only a lease.

Court’s Reasoning

The court applied the objective test and emphasized that acceptance must be proven by clear evidence. The offer to sell the building was made by letter. However, the plaintiff did not communicate acceptance by any written reply or equivalent method. The alleged acceptance existed only in the plaintiff’s mind.

Decision
The court held that there was no valid acceptance and therefore no contract of sale. Mental acceptance without communication is ineffective.

Principles Established

1. Acceptance can be made in writing.
2. Acceptance must be communicated unless waived.
3. Acceptance must be clear, unconditional, and final.

Illustration
If A sends a letter offering to sell land and B merely decides internally to accept without replying, no contract is formed.

3. Acceptance in Unilateral Contracts

A unilateral contract is one where acceptance is made by performance of an act rather than by communication.

Carlill v Carbolic Smoke Ball Company

Facts Explained

The company advertised that it would pay £100 to anyone who used its smoke ball product for two weeks and still contracted influenza. The advertisement stated that money had been deposited in a bank to demonstrate seriousness. Mrs Carlill used the product exactly as instructed but still became ill. She claimed the reward.

The company argued that:

1. The advertisement was not an offer but an invitation to treat.
2. Acceptance was not communicated.

Court’s Reasoning and Decision

The court held that the advertisement was a clear unilateral offer to the public. By performing the required conditions, Mrs Carlill accepted the offer. Communication of acceptance was waived because the company required performance as the method of acceptance.

Principles Derived

1. Acceptance may be by conduct.
2. Where an offer waives the need for communication, performance is sufficient.
3. Acceptance must be final and unqualified.
4. Performance in accordance with the terms creates a binding contract.

Illustration
A company offers a reward for finding a lost document. Anyone who returns it in accordance with the stated conditions accepts the offer by performance.

4. Modification of Offer and Counter Offers

Acceptance must mirror the offer. Any variation or modification is treated as a counter offer.

Hyde v Wrench

Facts Explained

The defendant offered to sell a farm for £1,000. The plaintiff replied offering £950. The defendant did not accept this. The plaintiff later attempted to accept the original £1,000 offer.

Decision
The court held that the counter offer destroyed the original offer. Since the original offer no longer existed, it could not be accepted later.

Legal Principle

A counter offer terminates the original offer.

Illustration
If A offers to sell a car for GHS 20,000 and B responds with GHS 18,000, the original offer is terminated.

5. Mere Enquiry Distinguished from Counter Offer

A request for clarification does not amount to a counter offer.

Stevenson Jacques v McLean

Facts Explained

The defendant offered to sell iron at a fixed price and stated that the offer was open until Monday. The plaintiff sent a telegram asking about delivery terms and payment arrangements. The defendant treated this as a rejection and sold the goods to another buyer.

Decision
The court held that the plaintiff’s message was a mere enquiry, not a counter offer. The original offer was still open.

Legal Principle

Seeking clarification does not terminate an offer.

Illustration
Asking about payment details or delivery time does not amount to rejection.

6. Acceptance and Inquiries in Ghanaian Law

NTHC v Antwi

Facts Explained
The defendant company offered to sell staff bungalows to employees and stated the price and deadline for response. The plaintiff replied accepting the offer and asking about banking and payment details. The company later dismissed the plaintiff and refused to proceed with the sale.

Court’s Reasoning
The court held that objectively, the company made a clear offer. The plaintiff accepted the essential terms, namely the price and the property description. The request for banking details was a mere inquiry and not a counter offer.

Decision
A binding contract existed.

Principles Established

1. Acceptance must be communicated.
2. Counter offers nullify the original offer.
3. Mere inquiries do not affect acceptance.

Illustration
Accepting a house price but asking how payment should be made does not destroy acceptance.

Domins Fisheries Ltd v Bremen-Vegesacker Fisheries

Facts

The plaintiffs entered into a contract with the defendants for the sale of a fishing motor vessel. The defendants sought to revoke the offer stating that there had been no acceptance. The plaintiffs by asking about a three-month moratorium constituted a counter offer which they rejected. 

Court Reasoning

A revocation of an offer can only be effective if communicated to the offeree before the offer is accepted. A request for moratorium on payment installments was a mere enquiry not a counter offer. 

Holding

There was a binding agreement between the parties. 

7. Prescription of Mode of Acceptance

The offeror may prescribe how acceptance is to be communicated.

Reasons for Prescribing Mode

1. Certainty and clarity
2. Ease of proof
3. Speed and efficiency
4. Commercial and industry practice

Alternative Modes of Acceptance

Where the prescribed method is not mandatory, any equally effective method may suffice.

Tinn v Hoffman

Facts Explained

The offer required acceptance by return post. The offeree instead delivered acceptance personally.

Decision
The court held that personal delivery was equally effective and reasonable. A valid contract was formed.

Principle
Where the prescribed method is not exclusive, a reasonable alternative may be used.

8. Postal Rule of Acceptance

Under the postal rule, acceptance is complete when the letter is posted, not when it is received.

Adams v Lindsell

Facts Explained
The defendant offered to sell wool. The plaintiff posted a letter of acceptance. Before receiving the letter, the defendant sold the wool to another buyer.

Decision
The court held that the contract was formed when the acceptance letter was posted. The defendant was liable for breach.

Legal Effect
Once acceptance is posted, the offeror is bound even if the letter is delayed or lost.

9. Silence as Acceptance

Silence generally does not amount to acceptance.

Felthouse v Bindley

Facts Explained
An uncle offered to buy his nephew’s horse and stated that if the nephew did not reply, silence would mean acceptance. The nephew did not respond. The horse was later sold to someone else.

Decision
The court held that silence cannot be imposed as acceptance. There was no contract.

Principle
Acceptance must be actively communicated unless waived in a unilateral contract context.

10. Instantaneous and Electronic Acceptance

With modern communication, acceptance by email, WhatsApp, and online platforms is treated as instantaneous.

Legal Rules

1. Acceptance is effective when received by the offeror.
2. Electronic acceptance is deemed effective when it leaves the offeree’s control and enters the information processing system of the offeror.
3. Delivery to the server or platform is treated as receipt.

11. Digital Signatures and Ghanaian Law

Electronic Transactions Act, 2008 (Act 772) Section 10

Where the law requires a signature, a digital signature is valid if:

1. It is linked to the signatory.
2. It is under the control of the signatory.
3. Any alteration after signing is detectable.

Effect
Electronic acceptance through digital signing is legally enforceable in Ghana.

TERMINATION OF OFFER

An offer may be terminated before acceptance in three main ways.

12. Rejection

Express refusal or counter offer terminates the original offer.

Hyde v Wrench applies.

13. Lapse of Time

An offer must be accepted within a reasonable time.

Aning v Kinful

Facts Explained
A man promised to marry a woman under ordinance marriage. They lived together for six years without fulfilling the promise. The woman sued for breach.

Decision
The court held that the promise should have been performed within a reasonable time. The delay constituted breach.

Principle
Offers and promises are not indefinite. Reasonable time depends on circumstances.

14. Revocation of Offer

Revocation is the withdrawal of an offer before acceptance.

Rules of Revocation

1. Must occur before acceptance.
2. Must be communicated to the offeree.
3. Becomes effective upon receipt, not posting.

Byrne & Co v Leon Van Tienhoven

Facts Explained
The defendant posted an offer on October 1. On October 8, they posted a letter revoking the offer. The plaintiff posted acceptance on October 15 before receiving the revocation. The revocation letter arrived on October 20.

Decision
The court held that revocation was ineffective because it was not received before acceptance. A binding contract existed.

Principle
The postal rule does not apply to revocation.

15. Promise to Keep an Offer Open

Common Law Position

Routledge v Grant

A promise to keep an offer open is not binding unless supported by consideration.

Ghanaian Position

Under Contracts Act, 1960 (Act 25) Section 8(1), a promise to keep an offer open is binding even without consideration. However, the offeror may still revoke but will be liable to pay compensation.
