A. Torts concerning harm to economic interests and the protection of personal reputation
21.1.1 This section outlines the law in relation to two groups of torts: the first protects a person against harm to his trade and economic interests resulting from the deliberate acts of another; the second, comprising defamation and malicious falsehood, is concerned with the protection of one’s reputation.
B. Local modifications to principles of English law
A. Cause of action: where one party induces another to breach a contractual obligation owed to a third-party
21.2.1 If A knows that B owes a contractual obligation to C, and procures or induces B to breach the said obligation such that C incurs damage as a result, A is liable to C for inducing the breach of B’s contract obligation to C.
(1) Mental element: knowledge of contractual relationship and intention to induce breach
21.2.2 To establish this cause of action, it must be proven that (a) A knows of the existence of B’s contractual relationship with C, and (b) that A has intended the breach of the obligation. A’s knowledge may be inferred from surrounding circumstances, and need not relate to the precise terms of the contract.
(2) Inducement must be a direct and effective cause of breach
21.2.3 Further, A’s action must be a direct and effective cause of B’s breach. This requirement is most obviously satisfied when A directly persuades B, whether with the promise of reward or incentives or otherwise, to commit the relevant breach.
(3) Essential for inducement to result in breach
21.2.4 It is essential that A’s inducement results in the breach of B’s contractual undertaking to C. This does not, however, require proof that the breach in question results in any liability. Thus, it will suffice if it is proven that B is in breach of his contractual obligation, but does not in fact incur any liability by reason, for instance, of an operative exemption clause.
(4) Damage must have been sustained due to breach
21.2.5 The aggrieved party must have sustained damage as a result of the breach of contract. Such damage may be inferred from the surrounding circumstances.
B. Defence of justification operational in exceptional circumstances
21.2.6 A person’s interference with another’s contract may be justified in exceptional circumstances. The precise scope of this defence is unclear, but it is generally thought to be a narrow defence which can only be founded upon a careful examination of all the facts. Some instances in which the defence has succeeded include those where the interference is the inevitable result of asserting a pre-existing legal right, or where it is necessary for the protection of public morals.
C. Tort extended to inducing breach of other non-contractual obligations
21.2.7 The tort of inducing breach of contract has been extended to other types of enforceable obligations. Thus, a person who induces another to breach a statutory or an equitable obligation may also commit an actionable tort.
A. Cause of action: where threat of unlawful conduct is made to prevent another’s conduct, resulting in harm to a third-party
21.3.1 If A makes a threat of unlawful conduct against B so as to prevent B from doing that which he is entitled to do, resulting in harm to C, A is liable to C.
(1) Threat must relate to unlawful conduct and must be compelling
21.3.2 The threat made by A must have the effect of compelling B to comply with A’s wishes so as to avoid the unpleasant consequences threatened by A. It is insufficient if A merely makes idle abuses of which B takes little or no notice. The threat must also relate to unlawful conduct, such as the commission of a crime, tort, or contractual breach.
(2) Tort actionable only where aggrieved party suffers damage due to threat
21.3.3 This tort is only actionable where the aggrieved party, C, has suffered damage as a result of A’s threat. Such damage includes all intended losses as well as damages that are not too remote.
B. Tort actionable in both two-and three-party interference
21.3.4 It is generally accepted that the tort of intimidation may take the form of either a two or three-party interference. In a case involving three parties, A threatens B with a view to cause loss to C. Where there are only two parties, A makes an unlawful threat against B and cause loss to B. However, the imposition of tortious liability in this latter situation is more controversial because it has the tendency to obscure the distinction between the tort of intimidation and the threatened unlawful act.
A. Cause of action: where two or more persons agree on course of conduct to harm another
21.4.1 Two or more persons commit the tort of conspiracy if they agree on a course of conduct to harm another. A conspiracy to commit an illegal act may also amount to a criminal offence. In the civil sphere, the tort of conspiracy may either be a straightforward conspiracy to injure, or a conspiracy using unlawful means.
B. Conspiracy to injure
(1) Conspirators must have shared a common design and acted or taken step to further that design
21.4.2 The agreement or combination between the alleged conspirators is a rudimentary element of the tort of conspiracy to injure. Whether such agreement exists is largely a question of fact. The agreement may either be express or of a tacit nature. However, the mere proof of an agreement is insufficient as it has to be demonstrated that each of the conspirators has acted, or taken some step to further their common design.
(2) Intention to injure must be the predominant purpose of conspirators’ actions
21.4.3 The conspirators’ intention to harm the victim is the gist of this tort. Thus, it is necessary to prove that such ill-intent is the predominant purpose with which the conspirators acted. It follows that where it can be proven that the design of the alleged conspirators is motivated by some legitimate purpose (such as the protection of their own economic interests), the tort is not made out even if injury to the victim is an unavoidable consequence of the scheme.
(3) Damage: victim must have suffered pecuniary loss
21.4.4 The victim of the conspiracy has to prove that he has suffered pecuniary loss. It is generally sufficient if such losses can be inferred from the surrounding circumstances.
C. Conspiracy by unlawful means
(1) Tort characterised by use of unlawful means and intention to harm need not be predominant motive
21.4.5 A conspiracy using unlawful means is unlike the simple conspiracy to injure in two ways: first, it is characterised by the use of unlawful means; and secondly, while it requires proof of the conspirators’ intention to harm the victim, such intention does not have to be their predominant motive.
(2) Unlawful means: concept as yet unsettled but may encompass any illigality that is an effective link between act of combination and injury
A. Cause of action: where a persons intentionally injures another by employing unlawful means against an intermediary
21.5.1 At common law, A commits a tort against B if A (a) commits an unlawful act affecting a third party C (b) with the intention to injure B and (c) such conduct does in fact result in damage to B. Unlike the tort of inducing breach of contract, this tort is not primarily concerned with the protection of pre-existing legal obligations, but with proscribing indirect harm inflicted through the use of unlawful means on an intermediary.
B. Mental element: intention must be to injure victim through conduct
21.5.2 The mental element of this tort appears to be a narrow one: the alleged tortfeasor must have intended to injure the victim as an end in itself or as a means to an end. The fact that the alleged tortfeasor’s (unlawful) conduct would inevitably injure the victim is not, by itself, sufficient.
C. Unlawful means
(1) Unlawful means must be directed at third-party intermediary but unclear as to whether it has to be independently actionable
21.5.3 Since the House of Lords decision in OBG v Allan [2008] 1 AC 1, it is reasonably clear that the illegality must have been applied to a third party intermediary with the result of causing damage to the plaintiff. However, it is unclear whether the illegality must also be separately actionable as a civil wrong. The alternative view is that any legal wrong, even one that is not independently actionable, will suffice so long as it is an effective causative agent of the victim's loss. A number of authorities from other leading jurisdictions (see OBG v Allan [2008] 1 AC 1 and AI Enterprises Ltd v Bram Enterprises Ltd [2014] SCC 12) have adopted the former view – that “unlawful means” should be restricted to independently actionable wrongs. In Singapore, however, our courts have yet to make any definitive pronouncement in this regard.
(2) Breach of statutory duty: tort generally non-actionable unless claimant falls within class of persons that statute was imposed to benefit, or has suffered special damage
21.5.4 As a general rule, statutory duties enforceable by way of criminal prosecution are presumed to be enforceable only in that manner. There are, however, two exceptional situations in which such statutory breaches could constitute ‘unlawful means’ for purposes of civil actions. First, if a statutory provision is, on its true construction, imposed for the benefit of a class of persons, a complainant who falls within that class may plead that his or her interests have been unlawfully interfered with. Secondly, where a statutory provision creates a public right, a complainant may enforce the breach of the provision in a civil suit if he or she has suffered special damage over and above that suffered by the public at large.
A. Cause of action: where two or more persons agree on course of conduct to harm another
21.6.1 A person is liable for malicious falsehood if he or she maliciously makes false representations in respect of another with a view to injure that person’s goodwill or economic reputation.
B. Elements of the tort
(1) Falsehood: false statement is made in respect of complainant’s person, property or trade
21.6.3 The element of falsehood is generally satisfied by proving that the tortfeasor has made a false statement in respect of the complainant’s person, property or trade. The offending representation may be verbal, written, or implied by conduct. It must also have been published to third persons (other than the complainant).
(2) Malice: evidence of personal ill-will and spite, or intention to injure, is sufficient
21.6.4 Malice may be established by proof that the maker of a statement knows of the untruth of a statement, or is reckless as to its truth. Mere negligence is not malice, but evidence of personal ill-will and spite, or an intention to injure, would suffice.
(3) Special damage: generally required except where false statements are in writing or permanent form and calculated to cause pecuniary injury
21.6.5 At common law, the tort of malicious falsehood is only actionable upon proof that the complainant has sustained special damage. This may require, for instance, evidence of quantifiable losses arising from loss of sales or asset devaluation. Note, however, that this aspect of the common law has been modified by section 6 of the Defamation Act (Cap 75, 1985 Rev Ed), such that the proof of special damage may be dispensed with if the false statements are published in writing or permanent form, and are calculated to cause pecuniary injury to the complainant in respect of his or her office, profession, calling, trade or business.
A. Introduction
(1) Competing interests: protection of personal reputation and upholding rights of free speech and public communication
21.7.1 The objectives of the tort of defamation are, on the one hand, to protect personal reputation and, on the other, to ensure that the right of free speech and public communication are not unduly compromised. Within the tort of defamation, these competing interests and rights have to be judiciously balanced.
(2) Two forms: libel and slander
21.7.2 There are two forms of defamation: libel (words in permanent form) and slander (words in temporal or transient form). Libel is actionable per se without proof of special damage whilst slander would require such proof, unless specific common law and statutory exceptions apply. For example, special damage is not required to be proved in respect of words calculated to disparage the plaintiff in any office, profession, calling, trade or business held or carried on at the time of the publication (see section 5 of the Defamation Act).
(3) Criminal defamation: not the focus of this section
21.7.3 Apart from the civil tort of defamation, section 499 of the Penal Code provides for the offence of criminal defamation. For the prosecution of such an offence, it must be shown that the accused made the publication with the intention to harm the reputation of the defamed person, or knows or has reason to believe that such harm would result. The focus of this section is, however, on the civil tort of defamation.
B. Elements of the cause of action
21.7.4 The three main requirements for a cause of action under the tort of defamation are as follows:
  1. The statement must be defamatory in nature;
  2. The statement must refer to the plaintiff; and
  3. The statement must be published.
(1) Defamatory in nature: based on the objective reasonable man test
(a) Defamation found if plaintiff is: lowered in estimation of society, shunned or avoided, or exposed to hatred, contempt or ridicule
21.7.5A statement is defamatory in nature if it tends to (i) lower the plaintiff in the estimation of right-thinking members of society generally, or (ii) cause the plaintiff to be shunned or avoided; or (iii) expose the plaintiff to hatred, contempt or ridicule. This is based on the objective reasonable man test. The judge determines whether the test is satisfied in a particular case upon hearing the evidence adduced at the trial. There are no jury trials in Singapore.
(b) Defamation may be found in natural and ordinary meaning of words or by true or legal innuendo
21.7.6 In terms of construction, a statement may be defamatory in two ways: (i) via the natural and ordinary meaning of the words used or as may be reasonably inferred from the words; and (ii) by way of true or legal innuendo. True innuendo arises from words which appear innocuous, but may be understood to be disparaging of the plaintiff by third parties who have knowledge of special facts which are not generally known. To support a cause of action based on true innuendo, the plaintiff will have to plead those special facts known to such third parties to whom the statement has been published.
(2) Reference to plaintiff: words must be reasonably understood by third party to refer to plaintiff
21.7.7 The plaintiff must show that the third party would reasonably understand the defamatory words to refer to the former. The intention of the defendant to defame the plaintiff is not a prerequisite. Thus, the defamation action may still succeed notwithstanding that the defendant did not intend to refer to the plaintiff, but to some other person or even a fictitious character bearing the same name.
(a) Action by non-natural persons
21.7.8 Apart from natural persons, legal persons such as incorporated bodies (including companies) and some unincorporated bodies (for example, societies registered under the Societies Act (Cap 311, 1985 Rev Ed) with the capacity to sue and be sued in its own name) may also bring defamation actions against persons who have made defamatory statements adversely affecting their commercial, trading or governing reputations.
(b) Group defamation
21.7.9 In class or group defamation actions, the issue is whether the defamatory statement, though targeted at a class or group, is nonetheless reasonably understood by the reasonable third party to refer to the individual claimant(s). To ascertain whether such reference exists, criteria such as the group size, the generality and extravagance of the defamatory statement and other factors may be taken into consideration.
(3) Publication: statement must be communicated to third parties who would reasonably understand it to be defamatory
21.7.10 The defamatory statement must have been communicated to third parties who would reasonably understand the statement to be defamatory of the plaintiff. Thus, the communication of the defamatory statement to the plaintiff alone would not be sufficient.
C. Defences
(1) Justification: where statement is proven to be true in substance and in fact
21.7.11 The plaintiff is not required to prove that the defamatory statement is false. Instead, the defendant may establish the defence of justification by proving that the defamatory statement is true in substance and in fact. Where the allegedly defamatory statement is a comment, both the facts on which the comment is based and the comment itself must be substantiated. Similarly, where an innuendo is pleaded, both the statement and the innuendo have to be justified. Particulars of the statement(s) of fact and the true facts relied upon by the defendant must be pleaded (Order 78 Rule 3(2), Rules of Court). The defendant is not required to substantiate every charge so long as the unsubstantiated charges do not materially injure the plaintiff’s reputation (see section 8 of the Defamation Act). The defence of justification normally constitutes a complete defence against the plaintiff’s claims.
(2) Fair comment: an expression of opinion based on true facts that is fair and relates to a matter of public interest
21.7.12 To succeed in the defence of fair comment, the defendant has to show that
  1. the words complained of are in the nature of a comment (that is, an expression of opinion as opposed to facts);
  2. the comment is based on true facts – it is not necessary to prove the truth of all allegations of facts but only those facts alleged or referred to in the defamatory words which form the basis of the opinion (see section 9 of the Defamation Act);
  3. the comment is fair, that is, it must be an honestly-held opinion of a fair-minded person though some allowance may be given for prejudices and exaggeration; and
  4. the comment relates to a matter of public interest, that is, a matter which the public at large may legitimately be interested in or concerned with.
(3) Privilege
21.7.14 The next defence against the plaintiff’s claim in defamation is based on the concept of privilege. There are two types of privilege: absolute and qualified privilege. Absolute privilege cannot be defeated by the plaintiff’s proof that the defendant’s statements were motivated by malice. On the other hand, qualified privilege can be defeated by proof of malice. A statement is made maliciously if it was actuated by dominant improper motive(s). In addition, a statement which is made without belief in its truth or recklessly (that is, with indifference to its truth or falsity) is one that is published with malice.
(a) Absolute privilege: defence cannot be defeated by proof of defendant’s malice
21.7.15 Absolute privilege arises in the following situations or circumstances:
  1. Parliamentary proceedings – the Members of Parliament are conferred immunity from both civil and criminal actions in respect of defamatory statements made in the course of parliamentary proceedings (see section 6 of the Parliament (Privileges, Immunities and Powers) Act (Cap 217, 2000 Rev Ed)). Similarly, the reports, papers and journals relating to the proceedings the publication of which is authorised by Parliament are immune from suit (see section 7 of the Parliament (Privileges, Immunities and Powers) Act).
  2. Judicial proceedings – immunity is conferred on the judges, counsel, witnesses and parties in respect of statements made in the course of or for the purposes of judicial proceedings, including proceedings conducted by tribunals and bodies recognised by law and acting judicially. The fair, accurate and contemporaneous reports of judicial proceedings which are publicly heard are also absolutely privileged (section 11 of the Defamation Act). This privilege extends to a ‘fair and bona fide’ comment on such report.
  3. Executive matters – this generally covers communications made by ministers and civil servants relating to state affairs.
(b) Qualified privilege: defence can be defeated by proof of defendant’s malice
21.7.16 The defence of qualified privilege arises in the following instances:
  1. Where the defendant has an interest or duty to communicate information and the third party has the corresponding interest or duty to receive the information – for instance, communications made by solicitors for the purposes of advancing clients’ interests and communications between employers and employees in relation to work matters are ordinarily accorded qualified privilege.
  2. Where the defendant makes a statement with a view to protect his or her self-interests (such as when he or she is responding to accusations), such statements are privileged to the extent that they are published bona fide as well as relevant and necessary to protect such interests.
  3. Where reports of parliamentary and judicial proceedings are fair and accurate, qualified privilege arises at common law (that is, outside the scope of the statutory provisions). Newspaper reports of parliamentary and judicial proceedings in the Commonwealth are also accorded qualified privilege statutorily (section 12 of the Defamation Act).
(4) Innocent dissemination: where intermediary did not know publication was libelious, could not have been alerted to libellous content in the circumstances and was not negligent
21.7.17 The defence of innocent dissemination is generally available to intermediaries such as retail vendors, libraries and delivery agents. To avail of such a defence, the intermediary who participated in the distribution of the defamatory statements must show that he or she did not know that the publication was libellous, the circumstances or work could not have alerted the defendant to the libellous content and that such ignorance was not due to his or her negligence.
(5) Offer of amends:: where defendant shows that statement was made ‘innocently’, offers to make a public apology and informs recipients of publication of defamatory content
21.7.18 The Offer of Amends is a procedure which permits a defendant to ward off a potential defamation action (or to procure, if the action has already commenced, its discontinuation thereof). The defendant has to first show that he or she has ‘innocently’ defamed another person and exercised all reasonable care in relation to the publication. The defendant must also offer to make a public apology and to take reasonably practicable steps to inform the persons who have been distributed with the copies of the publication that the contents are defamatory of the aggrieved party. The Offer of Amends constitutes a defence against any defamation action by the aggrieved party. If the offer is accepted by the aggrieved party and its terms are complied with by the defendant, the aggrieved party is precluded from suing the defendant in respect of the defamatory publication (see section 7 of the Defamation Act).
(6) Assent by plaintiff: clear and unequivocal assent to publication of defamatory statement
21.7.19 Where the plaintiff had clearly and unequivocally assented to the publication of the defamatory statement, that constitutes a valid defence to the defamation action.
D. Remedies
21.7.20 A plaintiff who has successfully established a cause of action in defamation against which there are no valid defences may obtain (a) monetary damages; and/or (b) injunctions restraining the publication, and/or (c) in exceptional circumstances, injunctions mandating that the defendant withdraw the defamatory statement.
(1) Damages: for vindicating reputation, providing consolation for distress and hurt and to repair damage to reputation
(2) Aggravated damages: awarded in appropriate cases for additional injury
21.7.22 Aggravated damages may be awarded in appropriate cases. Aggravated damages, which are compensatory in nature, may be awarded in respect of the additional injury caused by the defendant’s conduct or bad motives. For purposes of ascertaining damages, the plaintiff is required to give full particulars in the statement of claim of the details of any conduct by the defendant which has allegedly increased the injury suffered (Order 78 Rule 3(3A), Rules of Court). The amounts for both general compensatory and aggravated damages (if any) are awarded to the plaintiff in one lump sum, though a breakdown of the respective sums should be provided.
(3) Exemplary damages: awarded as a deterrent measure against expectation of profit of gain through publication
21.7.23 Exemplary or punitive damages are less common. Nonetheless, exemplary damages may be awarded as a deterrent measure where the defendant had published the defamatory statement in the expectation of profit or gain beyond the amount of compensatory damages payable and was aware that the publication was untrue.
(4) Mitigation of damages: through apology or undertaking not to republish
21.7.24 The defendant may make or offer an apology with a view to mitigating damages (see section 10 of the Defamation Act). Similarly, an undertaking by the defendant not to republish would generally go towards the mitigation of damages.
(5) Prohibitory Injunctions: to prevent future publication of defamatory materials
21.7.25 Prohibitory injunctions are usually granted to prevent the future publication of defamatory materials only where such further publication is reasonably apprehended. The courts are generally more cautious of issuing interlocutory injunctions, and will do so only where it is clear that the words complained of were libellous and no defence could possibly apply.
E. Internet defamation
21.7.26 With the advent of technology, globalisation and rise in the usage of the Internet, defamation in cyberspace is a real issue today. This problem, though not unique to Singapore, can have a significant impact considering the high proportion of Internet usage within the country for private, commercial and public purposes.
(1) Network service providers: protected if merely providing access to materials
21.7.27 With respect to the role of Network Service Providers (NSPs), section 26 of the Electronic Transactions Act (Cap 88, 2011 Rev Ed) protects a network service provider from liability arising from the making, publication, dissemination or distribution of third party materials, if the NSP were merely providing access to such materials. A third party refers, in this context, to a person over which the NSP has no effective control.
