India’s Judiciary on Unfair Trade Practices: From Passing Off to Comparative Advertising

When a business competes unfairly – by imitating a rival’s brand, spreading false claims, or leaking stolen trade secrets – the damage extends beyond just the affected company. Consumers are deceived, market trust erodes, and honest players are penalised for playing by the rules. In India, where there is no single unified statute against unfair competition, the judiciary has carried much of this weight. Through decades of landmark rulings, Indian courts have developed a sophisticated body of case law that defines, limits, and penalises specific categories of unfair trade practices – from classic passing off and misleading advertising to trade secret misappropriation and disparaging comparative ads.

The foundational role of the judiciary in regulating unfair competition 🔗

India’s legal framework against unfair competition is fragmented across several statutes – including the Trade Marks Act, 1999, the Consumer Protection Act, 2019, and the Competition Act, 2002 – with no single overarching unfair competition law. As the Oxford Journal of Intellectual Property Law & Practice notes, India offers a menu of specific statutory options, common law torts, and equitable actions to address unfair competition. This means courts must actively interpret and apply these tools to each new situation that arises. The result is a rich judicial tradition where the contours of unfair trade practice have been drawn almost entirely through case law.

Passing off: protecting goodwill without a registered trademark 🔗

Passing off is the most frequently invoked common law tort in Indian unfair competition litigation. Its core principle – that no one may sell their goods under the pretence that they are someone else’s – has ancient common law roots but continues to be actively applied by Indian courts today.

The classic trinity: goodwill, misrepresentation, damage 🔗

The Supreme Court in Laxmikant V. Patel v. Chetanbhai Shah (2002) clarified the three essential elements a plaintiff must establish to succeed in a passing off action: first, the existence of goodwill or reputation attached to their goods or services; second, a misrepresentation by the defendant that is likely to cause consumer confusion; and third, actual or potential damage to the plaintiff’s goodwill resulting from that misrepresentation. These three elements – often called the classical trinity – provide the structural test that courts have consistently applied across sectors.

Transborder reputation and the Whirlpool principle 🔗

A particularly significant development came in N.R. Dongre v. Whirlpool Corporation (1996), where the Supreme Court upheld Whirlpool’s passing off claim against a local manufacturer using the same trademark – even though Whirlpool had no manufacturing presence in India at the time. The court recognised Whirlpool’s transborder reputation built through international magazine circulation among Indian consumers. This ruling significantly expanded the scope of passing off protection beyond businesses with a direct commercial footprint in India.

Similarly, in Honda Motors Co. Ltd. v. Charanjit Singh, the Delhi High Court restrained an Indian manufacturer from selling pressure cookers under the “Honda” name. The court reasoned that the name had become so associated with the Japanese automobile brand that any use of it on unrelated goods would mislead consumers and damage the plaintiff’s goodwill. These cases together demonstrate that passing off protects reputation as a business asset, regardless of whether a trademark is registered.

Misleading representation: when false claims become actionable 🔗

Misleading representation covers a wider and more consumer-facing set of practices. Courts have consistently held that false or deceptive claims about a product’s quality, composition, certification, or characteristics constitute both an unfair trade practice and a harm to the consuming public.

Statutory backing under the Consumer Protection Act, 2019 🔗

The Consumer Protection Act, 2019 defines misleading advertisement under Section 2(28) as any advertisement that falsely describes a product’s qualitative characteristics, makes representations amounting to unfair trade practice, or withholds information that consumers need to make informed choices. Under Section 89 of the Act, manufacturers who promote false or misleading advertisements face imprisonment up to two years and fines up to ten lakh rupees. The Central Consumer Protection Authority (CCPA) established under the Act is further empowered to investigate and issue directions against such practices.

Judicial application: institutions misleading consumers 🔗

The courts have applied this framework to diverse factual situations. In Miss Sonika Tandon & Ors. v. Rauf Muslim Jamia Bahera, a dental institute advertised recognition by the Dental Council of India and adequate facilities – none of which existed in reality. The court held this to be a clear case of misleading representation. Judicial intervention in such cases has a dual purpose: protecting the competitor who loses business unfairly, and protecting the consumer who has been deceived into relying on false information. Indian courts have consistently treated these two interests as interlinked.

Discrediting competitors: where competition becomes defamation 🔗

Competition law recognises that businesses will promote their own products – sometimes aggressively. But the law draws a firm line between legitimate promotion and malicious disparagement of a competitor’s goods. Indian courts have developed a nuanced framework to identify where that line falls.

Trade dress and product packaging 🔗

In Colgate Palmolive Company v. Anchor Health & Beauty Care Pvt. Ltd. (2003), the Delhi High Court held that a product’s distinctive packaging, colour combination, and overall presentation – known as trade dress – is entitled to protection against deceptive imitation. When a competitor copies trade dress to create consumer confusion, it amounts to unfair competition even if individual elements of the packaging might not independently qualify for trademark protection.

The principle was reaffirmed in ITC Limited v. Philip Morris Products SA & Ors. (2010), where the court prevented the use of packaging that could mislead consumers about the product’s origin. These decisions confirm that the overall commercial impression a product creates is a protectable asset, and courts will intervene when a competitor deliberately replicates that impression.

Trade secret misappropriation: breach of confidence as judicial remedy 🔗

India does not have a dedicated trade secret statute. Instead, courts have built protections through the equitable doctrine of breach of confidence, contractual obligations, and copyright principles applied to confidential information. The judiciary’s role here is especially important because, without legislative guidance, it has had to define the boundaries of protection on a case-by-case basis.

Diljeet Titus v. Alfred A. Adebare (2006): confidential data as intellectual property 🔗

This Delhi High Court decision is foundational. When associates left a law firm and took client lists, proprietary documents, and business data with them, the court held that the confidential information constituted intellectual property of the employer and restrained the defendants from using it – even in the absence of a formal NDA. Crucially, the court did not bar the defendants from practising law; it only stopped them from using the specific material they had taken. This distinction between an individual’s skills and knowledge (which they may carry) and an employer’s confidential data (which they may not exploit) remains a guiding principle in trade secret litigation.

Burlington Home Shopping Pvt. Ltd. v. Rajnish Chibber (1995) and John Richard Brady v. Chemical Process Equipments Pvt. Ltd. (1987) 🔗

In Burlington, the Delhi High Court treated a customer database as confidential business property and restrained a former employee from using it. In John Richard Brady, the court went further and held that regardless of whether a formal contract exists, no one may take unfair advantage of information received in confidence. Together, these rulings establish that the obligation of confidentiality is not purely contractual – it is an independent equitable duty that courts will enforce.

Comparative advertising and disparagement: puffery vs. denigration 🔗

Comparative advertising – where one brand explicitly compares itself to a competitor – occupies a contested space in Indian law. Courts have confirmed that such advertising is legally permitted. However, a clear boundary exists between permissible promotion and unlawful disparagement.

The Pepsi v. Coca Cola framework 🔗

The landmark case of Pepsi Co. Inc. & Ors. v. Hindustan Coca Cola Ltd. (2003) is the most cited authority on this issue. Coca Cola ran advertisements where children were shown preferring a cola that closely resembled Pepsi’s packaging – only to be told they had made a “wrong choice” and that the drink was “meant for kids.” The Delhi High Court held that while a trader may assert their goods are better, they cannot, through comparison, slander, defame, or call a competitor’s goods bad or inferior. The court found that the advertisement, under the guise of puffery, crossed into denigration of Pepsi’s product and granted an injunction.

The court articulated the key test: whether the advertisement merely promotes the advertiser’s product, or whether – directly or indirectly – it portrays the rival’s product as inferior. Truthful comparative claims are permitted; untruthful or grossly misleading disparagement is not.

Reckitt & Colman cases: building the disparagement doctrine 🔗

Earlier cases set the doctrinal groundwork. In Reckitt & Colman of India Ltd. v. M.P. Ramchandran (1999), the Calcutta High Court established the principles for granting injunctions in disparagement cases, focusing on whether the advertisement’s overall effect was to promote the advertiser’s own goods or to demean the competitor’s. In Reckitt & Colman of India v. Kiwi TTK Ltd. (1996), the court restrained an advertisement where “Brand X” – identifiable as the plaintiff’s product – was shown cracking and dripping to imply inferiority, while the defendant’s product appeared flawless.

More recently, in Reckitt Benckiser (India) Pvt. Ltd. v. Hindustan Unilever Limited (2022), the Delhi High Court granted an injunction against an advertisement for Domex that did not merely claim superiority over Harpic but sent a clear message that Harpic failed entirely at addressing toilet odour. The court noted that the advertisement crossed from comparison into denigration.

The digital frontier: new forms of unfair practice 🔗

The rise of e-commerce and digital advertising has introduced new modes of unfair competition that courts are increasingly being called upon to address. In Marico Limited v. Adani Wilmar Ltd. (2021), the court tightened standards for misleading comparative advertisements circulated on digital platforms, recognising that social media and influencer marketing create a far wider consumer impact than traditional advertising. Domain squatting, keyword advertising abuse, and fake reviews are among the digital practices that Indian courts and regulators are progressively recognising as actionable unfair trade practices.

The Consumer Protection Act, 2019 specifically addresses e-commerce through its expanded definition of unfair trade practices and the CCPA’s mandate to investigate digital violations. This legislative-judicial coordination signals that India’s framework, while still evolving, is responsive to the realities of the digital marketplace.

What the case law tells us about India’s approach 🔗

Taken together, India’s judicial decisions on unfair trade practices reveal a consistent philosophy. Courts protect goodwill and reputation as commercial assets deserving legal recognition. They maintain a clear distinction between vigorous but honest competition and conduct that deceives, defrauds, or denigrates. They fill legislative gaps – particularly in trade secret law – through equitable principles. And they have shown willingness to adapt existing doctrines to new commercial environments, including the digital space. As the Oxford Academic analysis of Indian unfair competition law observes, the courts have developed a considerable body of jurisprudence that, while fragmented across different legal theories, collectively provides meaningful protection against a wide range of competitive abuses.

What do you think? Given that India still lacks a unified trade secret statute, should courts continue to rely on breach of confidence and contractual principles, or is there a stronger case for comprehensive legislation? And as comparative advertising on social media becomes increasingly difficult to regulate, do you think India’s current judicial framework is equipped to handle the scale and speed of digital disparagement?
