Allen v Sixteen Sterling Investments (Pty) Ltd 1974 (4) SA 164

Allen v Sixteen Sterling Investments (Pty) Ltd 1974 (4) SA 164

Facts

Allen entered into a written agreement to purchase a property from Sixteen Sterling Investments (Pty) Ltd. The agreement was based on a misrepresentation by Sixteen Sterling Investments' agent that the property was a certain size. Allen relied on this misrepresentation and entered into the agreement without inspecting the property.

After Allen had entered into the agreement, he discovered that the property was actually smaller than he had been told. Allen sought to cancel the agreement on the grounds that he had made a mistake. Sixteen Sterling Investments refused to cancel the agreement and demanded that Allen perform his obligations under the agreement.

Issue

The main issue in the case was whether Allen was entitled to cancel the agreement on the grounds that he had made a mistake.

Reasons

The Durban and Coast Local Division of the Supreme Court of South Africa held that Allen was entitled to cancel the agreement. The court found that Allen had made a unilateral error in corpore, which is a mistake about the identity of the subject matter of the contract. The court also found that Sixteen Sterling Investments' agent had been negligent in making the misrepresentation about the size of the property.

Unilateral error in corpore

A unilateral error in corpore is a mistake about the identity of the subject matter of the contract. In this case, Allen made a unilateral error in corpore because he was mistaken about the size of the property.

Negligence

Sixteen Sterling Investments' agent was negligent in making the misrepresentation about the size of the property. The agent had a duty to take reasonable steps to verify the size of the property before making a representation about it. The agent failed to take reasonable steps to verify the size of the property and therefore made a negligent misrepresentation.

Conclusion

The court held that Allen was entitled to cancel the agreement on the grounds that he had made a unilateral error in corpore induced by Sixteen Sterling Investments' agent's negligent misrepresentation.

Summary

The case of Allen v Sixteen Sterling Investments (Pty) Ltd 1974 (4) SA 164 is a landmark case in South African contract law. The case is particularly important for its analysis of the following issues:

• The concept of unilateral error in corpore;
• The effect of negligent misrepresentation on the formation of a contract; and
• The right to cancel a contract on the grounds of unilateral error in corpore induced by negligent misrepresentation.

Concept of unilateral error in corpore

A unilateral error in corpore is a mistake about the identity of the subject matter of the contract. It is a type of material mistake that can render a contract void.

Effect of negligent misrepresentation on the formation of a contract

Negligent misrepresentation is a false statement made by one party to a contract to the other party, without any intention to deceive, but without taking reasonable steps to verify the truth of the statement. Negligent misrepresentation can induce the other party to enter into the contract and, if so, the contract may be voidable.

Right to cancel a contract on the grounds of unilateral error in corpore induced by negligent misrepresentation

If a party to a contract makes a unilateral error in corpore induced by the other party's negligent misrepresentation, that party may be entitled to cancel the contract. This is because the party's consent to the contract was not free and genuine.

Impact of the Case

The case of Allen v Sixteen Sterling Investments (Pty) Ltd 1974 (4) SA 164 has had a significant impact on the law of contract in South Africa. The case has clarified the concept of unilateral error in corpore, the effect of negligent misrepresentation on the formation of a contract, and the right to cancel a contract on the grounds of unilateral error in corpore induced by negligent misrepresentation.

George v Fairmead (Pty) Ltd 1958 (2) SA 465 (AD)

George v Fairmead (Pty) Ltd 1958 (2) SA 465 (AD)

Facts

George was a salesman for Fairmead (Pty) Ltd. One day, he was asked to sign a document that he believed was a receipt for his commission. However, the document was actually a contract of service that gave Fairmead the right to terminate George's employment at any time without notice. George signed the document without reading it carefully.

A few months later, Fairmead terminated George's employment without notice. George sued Fairmead for breach of contract. Fairmead argued that George was bound by the contract of service and that it had therefore not breached its contract with George.

Issue

The main issue in the case was whether George was bound by the contract of service, even though he had signed it without reading it carefully.

Reasons

The Appellate Division of the Supreme Court of South Africa held that George was not bound by the contract of service. The court found that George had made a justus error when he signed the document, and that he was therefore not bound by it.

Justus error

A justus error is a mistake that is made by a reasonable person in the same circumstances. The court found that George had made a justus error when he signed the document because he had believed that it was a receipt for his commission.

Consent

Consent is one of the essential elements of a valid contract. If a party to a contract makes a justus error, then they have not consented to the terms of the contract and the contract is therefore void.

Conclusion

The court held that George was not bound by the contract of service because he had made a justus error when he signed it. The court therefore granted judgment in favour of George.

Summary

The case of George v Fairmead (Pty) Ltd 1958 (2) SA 465 (AD) is a landmark case in South African contract law. The case is particularly important for its analysis of the following issues:

• The concept of justus error in contract law;
• The effect of justus error on the formation of a contract; and
• The requirement of consent in contract law.

Concept of justus error in contract law

A justus error is a mistake that is made by a reasonable person in the same circumstances. The concept of justus error is important in contract law because it protects parties to contracts from being bound by contracts that they have entered into under mistake.

Effect of justus error on the formation of a contract

If a party to a contract makes a justus error, then they have not consented to the terms of the contract and the contract is therefore void. This is because consent is one of the essential elements of a valid contract.

Requirement of consent in contract law

Consent is one of the essential elements of a valid contract. Consent means that both parties to the contract must understand and agree to the terms of the contract. If there is no consent, then there is no contract.

National and Overseas Distributors Corporation (Pty) Ltd v Potato Board (1958 (2) SA 473 (A)

National and Overseas Distributors Corporation (Pty) Ltd v Potato Board (1958 (2) SA 473 (A)

Facts

The Potato Board invited tenders for the erection of a steel shed. The National and Overseas Distributors Corporation (Pty) Ltd (NODC) submitted a tender, which was mistakenly accepted by the Potato Board. The Potato Board later realized its mistake and informed the NODC that it had accepted the wrong tender. The NODC argued that a contract had been formed between the two parties and that the Potato Board was therefore bound to proceed with the contract.

Issue

The main issue in the case was whether a contract had been formed between the NODC and the Potato Board, despite the Potato Board's mistake.

Reasons

The Appellate Division of the Supreme Court of South Africa held that a contract had not been formed between the NODC and the Potato Board. The court found that the Potato Board's mistake was material and that the NODC was aware of the mistake.

Material mistake

A material mistake is a mistake that goes to the root of the contract. In this case, the Potato Board's mistake in accepting the NODC's tender was a material mistake, because it went to the very essence of the contract.

Awareness of the mistake

The NODC was aware of the Potato Board's mistake because the Potato Board had informed the NODC that it had accepted the wrong tender. The NODC therefore could not claim that it had entered into the contract in good faith.

Conclusion

The court held that the Potato Board's mistake was material and that the NODC was aware of the mistake. The court therefore concluded that no contract had been formed between the NODC and the Potato Board.

Summary

The case of National and Overseas Distributors Corporation (Pty) Ltd v Potato Board (1958 (2) SA 473 (A)) is a landmark case in South African contract law. The case is particularly important for its analysis of the following issues:

• The concept of mistake in contract law;
• The distinction between material and immaterial mistakes; and
• The effect of awareness of mistake on the formation of a contract.

Concept of mistake in contract law

A mistake is an erroneous belief about a fact that is relevant to the formation of a contract. Mistakes can be either material or immaterial.

Material and immaterial mistakes

A material mistake is a mistake that goes to the root of the contract and renders the contract void. An immaterial mistake is a mistake that does not go to the root of the contract and does not render the contract void.

Effect of awareness of mistake on the formation of a contract

If a party to a contract is aware of the other party's mistake, then the other party cannot claim that they entered into the contract in good faith. If the other party cannot claim that they entered into the contract in good faith, then no contract will be formed.

Impact of the Case

The case of National and Overseas Distributors Corporation (Pty) Ltd v Potato Board (1958 (2) SA 473 (A)) has had a significant impact on the law of contract in South Africa. The case has clarified the concept of mistake in contract law, the distinction between material and immaterial mistakes, and the effect of awareness of mistake on the formation of a contract.

Bloom v The American Swiss Watch Company (1915 AD 100)

Bloom v The American Swiss Watch Company (1915 AD 100)

Facts

Jewelry to the value of 5,000 pounds was stolen from the American Swiss Watch Company. The following day, the Company offered a reward of 500 pounds for information leading to the arrest of the robbers and recovery of the stolen property. Bloom furnished such information, but it was found by Judge Hopley that Bloom did not know about the reward. It was held that Bloom's case was dependent on establishing a contractual relationship between him and the company. Since the offer was public, it was still required that someone accept it to conclude a contract. Bloom did not give the information on the faith of the offer, so no vinculum could be established.

Issue

Whether Bloom had entered into a contract with the American Swiss Watch Company by providing information leading to the arrest of the robbers and recovery of the stolen property, even though he was not aware of the reward.

Reasons

The Appellate Division of the Supreme Court of South Africa held that Bloom had not entered into a contract with the American Swiss Watch Company. The court found that the offer of a reward was a unilateral offer, and that acceptance of the offer required communication of the acceptance to the offeror. Since Bloom was not aware of the reward at the time he provided the information, he could not have communicated his acceptance of the offer to the American Swiss Watch Company.

Unilateral offer

A unilateral offer is an offer that is accepted by performance of the act requested in the offer. Bloom's performance of the act requested in the offer (providing information leading to the arrest of the robbers and recovery of the stolen property) would have constituted acceptance of the offer, if Bloom had been aware of the offer at the time of performance.

Communication of acceptance

Acceptance of a unilateral offer must be communicated to the offeror. This is because the offeror needs to know that their offer has been accepted in order to be bound by the contract. Bloom did not communicate his acceptance of the offer to the American Swiss Watch Company because he was not aware of the offer at the time of performance.

Conclusion

The court held that Bloom had not entered into a contract with the American Swiss Watch Company because he had not accepted the offer of a reward.

Summary

The case of Bloom v The American Swiss Watch Company (1915 AD 100) is a landmark case in South African contract law. The case is particularly important for its analysis of the following issues:

• The requirements for a valid contract;
• The concept of a unilateral offer; and
• The requirement of communication of acceptance.

Requirements for a valid contract

The case established that there are three requirements for a valid contract:

1. Offer and acceptance;
2. Consideration; and
3. Intention to create legal relations.

Unilateral offer

The case established that a unilateral offer is an offer that is accepted by performance of the act requested in the offer.

Requirement of communication of acceptance

The case established that acceptance of a unilateral offer must be communicated to the offeror.

Impact of the Case

The case of Bloom v The American Swiss Watch Company (1915 AD 100) has had a significant impact on the law of contract in South Africa. The case has clarified the requirements for a valid contract, the concept of a unilateral offer, and the requirement of communication of acceptance.

Vasco Dry Cleaners v Twycross 1979 (1) SA 603 (A)

FIRAC Analysis of Vasco Dry Cleaners v Twycross 1979 (1) SA 603 (A)

Facts

Vasco Dry Cleaners (Vasco) was a dry cleaning business in South Africa. Twycross was a customer of Vasco. Twycross took a pair of trousers to Vasco to be dry cleaned. Vasco lost the trousers. Twycross sued Vasco for the loss of the trousers.

Issues

The main issue in the case was whether Vasco was liable for the loss of the trousers.

Reasons

The Appellate Division of the Supreme Court of South Africa held that Vasco was liable for the loss of the trousers. The court found that Vasco had a duty to take reasonable care of the trousers and that it had breached that duty by losing the trousers. The court also found that Twycross had suffered a loss as a result of Vasco's breach of duty.

Duty of care

The court held that Vasco had a duty to take reasonable care of the trousers. The court found that this duty arose from the contract between Vasco and Twycross. The court also found that the duty of care was a high one, as Vasco was a professional dry cleaner.

Breach of duty

The court held that Vasco had breached its duty of care by losing the trousers. The court found that Vasco had not taken reasonable care of the trousers and that it had failed to take any steps to prevent them from being lost.

Loss

The court held that Twycross had suffered a loss as a result of Vasco's breach of duty. The court found that the trousers were worth R25 and that Twycross was entitled to be compensated for their loss.

Conclusion

The court found in favor of Twycross and awarded him R25 in damages.

Summary

The case of Vasco Dry Cleaners v Twycross 1979 (1) SA 603 (A) is a landmark case in South African contract law. The case is particularly important for its analysis of the following issues:

• The duty of care in contracts;
• The breach of duty; and
• The assessment of damages.

Duty of care in contracts

The case established that parties to a contract have a duty to take reasonable care to avoid causing harm to the other party. The duty of care is a legal obligation that arises from the contract itself.

Breach of duty

The case established that a breach of duty occurs when a party to a contract fails to take reasonable care to avoid causing harm to the other party. The breach of duty must be a cause of the harm suffered by the other party.

Assessment of damages

The case established that the purpose of damages is to compensate the injured party for the loss suffered as a result of the breach of duty. The amount of damages awarded should be enough to put the injured party in the position they would have been in if the breach of duty had not occurred.

Impact of the Case

The case of Vasco Dry Cleaners v Twycross 1979 (1) SA 603 (A) has had a significant impact on the law of contract in South Africa. The case has clarified the duty of care in contracts, the breach of duty, and the assessment of damages.

Saambou- Nasionale Bouvereniging v Friedman (1979 (3) SA 978 (A)

Saambou- Nasionale Bouvereniging v Friedman (1979 (3) SA 978 (A)

Facts

Saambou-Nasionale Bouvereniging (Saambou) was a building society in South Africa. Friedman, a professional golfer, was approached by an advertising agency to endorse Saambou's products. Friedman agreed to endorse Saambou's products, but only on the condition that he would not be personally liable for any debts incurred by Saambou.

The advertising agency created an advertisement that featured Friedman and the following statement: "Saambou-Nasionale Bouvereniging. The bank that's always there for you." The advertisement was published in a number of newspapers and magazines.

After the advertisement was published, Saambou incurred significant losses. Saambou sued Friedman for breach of contract, alleging that he had failed to honour his endorsement agreement. Friedman denied that he had breached any contract with Saambou.

Issues

The main issue in the case was whether Friedman had entered into a contract with Saambou.

Reasons

The Appellate Division of the Supreme Court of South Africa held that Friedman had not entered into a contract with Saambou. The court found that Friedman had consented to the advertisement being published, but that he had not consented to the terms of the endorsement agreement. The court also found that Saambou had made a material mistake when it entered into the endorsement agreement, because Saambou believed that Friedman had agreed to be personally liable for any debts incurred by Saambou.

Mistake

The court held that Saambou's mistake was material because it went to the root of the contract. The court also held that Friedman was not aware of Saambou's mistake and that he had not done anything to induce Saambou's mistake.

Consent

The court held that Friedman had not consented to the terms of the endorsement agreement. The court found that Friedman had only consented to the advertisement being published and that he had made it clear to the advertising agency that he would not be personally liable for any debts incurred by Saambou.

Conclusion

The court dismissed Saambou's claim against Friedman.

Summary

The case of Saambou-Nasionale Bouvereniging v Friedman (1979 (3) SA 978 (A)) is a landmark case in South African contract law. The case is particularly important for its analysis of the following issues:

• The requirements for a valid contract;
• The concept of mistake; and
• The concept of consent.

Requirements for a valid contract

The case established that there are three requirements for a valid contract:

1. Offer and acceptance;
2. Consideration; and
3. Intention to create legal relations.

Mistake

The case established that a mistake can invalidate a contract if it is material and if the other party to the contract is not aware of the mistake.

Consent

The case established that both parties to a contract must consent to the terms of the contract in order for the contract to be valid.

Clipsal Australia Pty Ltd v Trust Electrical Wholesalers [2007] SCA 24 (RSA)

Clipsal Australia Pty Ltd v Trust Electrical Wholesalers [2007] SCA 24 (RSA)

Facts

Clipsal Australia Pty Ltd (Clipsal) was the proprietor of a registered design for a set of electrical accessory plates with surrounds. Trust Electrical Wholesalers (Trust) sold a set of electrical accessory plates with surrounds that Clipsal alleged infringed its registered design.

Clipsal sued Trust for infringement of its registered design. The High Court dismissed Clipsal's claim, finding that the design was not new or original and that it had not been infringed by Trust.

Clipsal appealed to the Supreme Court of Appeal (SCA).

Issues

The main issues in the case were:

• Whether the design was new and original; and
• Whether the design had been infringed by Trust.

Reasons

The SCA held that the design was new and original and that it had been infringed by Trust.

Novelty and originality

The SCA found that the design was new because it had not been disclosed to the public before the priority date of the design application. The SCA also found that the design was original because it was not substantially different from what had gone before.

Infringement

The SCA found that Trust's product infringed Clipsal's registered design because it was substantially similar to the registered design. The SCA found that the differences between the two designs were minor and that they did not alter the overall impression produced by the designs.

Conclusion

The SCA overturned the High Court's decision and found that Trust had infringed Clipsal's registered design. The SCA granted an injunction restraining Trust from infringing the design.

Summary

The case of Clipsal Australia Pty Ltd v Trust Electrical Wholesalers [2007] SCA 24 (RSA) is a landmark case in South African law. The case is particularly important for its analysis of the following issues:

• The requirements for novelty and originality in registered designs; and
• The test for infringement of registered designs.

Requirements for novelty and originality

The case established that a registered design must be both new and original in order to be valid. Novelty means that the design must not have been disclosed to the public before the priority date of the design application. Originality means that the design must be substantially different from what has gone before.

Test for infringement of registered designs

The case established that the test for infringement of registered designs is a visual test. The court must ask whether the infringing design is substantially similar to the registered design. If the infringing design is substantially similar to the registered design, then it will be found to infringe, even if there are minor differences between the two designs.

Impact of the Case

The case of Clipsal Australia Pty Ltd v Trust Electrical Wholesalers [2007] SCA 24 (RSA) has had a significant impact on the law of registered designs in South Africa. The case has clarified the requirements for novelty and originality in registered designs and the test for infringement of registered designs.

Buzbee (Pty) Ltd v Registrar of Patents 2010 BIP 42 (CP)

Buzbee (Pty) Ltd v Registrar of Patents 2010 BIP 42 (CP)

Facts

Buzbee (Pty) Ltd (Buzbee) applied to the Registrar of Patents (the Registrar) for two patents. The Registrar granted the patents, but later revoked them on the grounds that Buzbee had failed to file its counterstatement in time in response to a revocation application filed by a third party.

Buzbee appealed the Registrar's decision to the Cape High Court.

Issues

The main issue in the case was whether the Registrar was entitled to revoke Buzbee's patents on the grounds that Buzbee had failed to file its counterstatement in time.

Reasons

The Cape High Court held that the Registrar was not entitled to revoke Buzbee's patents on the grounds that Buzbee had failed to file its counterstatement in time. The court found that the Registrar's power to revoke patents was limited to the circumstances specified in the Patents Act 57 of 1978 (the Act). The court also found that the Act did not authorize the Registrar to revoke patents on the grounds that the counterstatement in a revocation application had not been filed in time.

The court found that the Registrar's decision to revoke Buzbee's patents was unreasonable and that it had violated Buzbee's right to a fair hearing. The court also found that the Registrar's decision had caused Buzbee commercial harm.

Conclusion

The court overturned the Registrar's decision and ordered the Registrar to reinstate Buzbee's patents.

Summary

The case of Buzbee (Pty) Ltd v Registrar of Patents 2010 BIP 42 (CP) is a landmark case in South African law. The case is particularly important for its analysis of the powers of the Registrar of Patents under the Patents Act 57 of 1978 (the Act).

Failure to file counterstatement in time

The case established that the failure to file a counterstatement in time in response to a revocation application is not a ground for revoking a patent. The Act does not authorize the Registrar to revoke patents on the grounds that the counterstatement in a revocation application has not been filed in time.

Right to a fair hearing

The case established that the Registrar must give patentees a fair hearing before revoking their patents. This includes giving patentees a reasonable opportunity to file a counterstatement in response to a revocation application.

Commercial harm

Payen Components SA Ltd v Bovic Gaskets CC and Others 1995 (4) SA 441 (A) 29

Payen Components SA Ltd v Bovic Gaskets CC and Others 1995 (4) SA 441 (A) 29

Facts

Payen Components SA Ltd (Payen) was a South African company that manufactured and sold gaskets. Bovic Gaskets CC (Bovic) was a South African company that also manufactured and sold gaskets.

Payen had developed a number of unique gasket identification codes, which were used to identify different types of gaskets. Bovic began using Payen's gasket identification codes in its own price lists and catalogues.

Payen sued Bovic for passing off. Payen claimed that Bovic's use of its gasket identification codes was likely to deceive or confuse consumers into thinking that Bovic's gaskets were associated with Payen.

Issues

The main issue in the case was whether Bovic's use of Payen's gasket identification codes was a passing off.

Reasons

The Supreme Court of Appeal held that Bovic's use of Payen's gasket identification codes was a passing off. The court found that the gasket identification codes were distinctive and that Bovic's use of the codes was likely to create the impression in the minds of consumers that Bovic's gaskets were associated with Payen.

Passing off

The court held that the following elements of passing off were present in the case:

• Goodwill: Payen had goodwill in its gasket identification codes.
• Misrepresentation: Bovic's use of Payen's gasket identification codes was likely to misrepresent to consumers that Bovic's gaskets were associated with Payen.
• Damage: Payen was likely to suffer damage as a result of Bovic's misrepresentation.

Conclusion

The court granted an interdict restraining Bovic from using Payen's gasket identification codes.

Summary

The case of Payen Components SA Ltd v Bovic Gaskets CC and Others 1995 (4) SA 441 (A) 29 is a landmark case in South African law. The case is particularly important for its analysis of the following issues:

• The law of passing off;
• The concept of goodwill;
• The elements of passing off; and
• The application of the law of passing off to product identification codes.

Law of passing off

The case established that the law of passing off protects the goodwill of businesses by preventing businesses from misrepresenting their goods or services as being those of another business.

Concept of goodwill

The case established that goodwill is the reputation and standing of a business in the minds of consumers. Goodwill can be attached to a business's name, trade marks, product identification codes, and other business assets.

Elements of passing off

The case established that the following elements must be present in order for a passing off claim to succeed:

• The plaintiff must have goodwill in a particular business asset, such as a trade mark, product identification code, or get-up.
• The defendant must misrepresent its goods or services as being those of the plaintiff.
• The plaintiff must be likely to suffer damage as a result of the defendant's misrepresentation.

The case established that the law of passing off can be applied to product identification codes. The case also established that the courts will consider a number of factors in determining whether the use of a product identification code is a passing off, including the distinctiveness of the code, the extent to which the code is used by the plaintiff and other businesses, and the likelihood of confusion among consumers.
