Clarifying Liability: The Case of the Contaminated Chocolate

You open a chocolate bar only to find insects inside. Your first instinct is to hold the manufacturer accountable – and that seems reasonable. But what if the law doesn’t work quite that simply? A consumer complaint involving a Cadbury chocolate allegedly containing worms and fungus reached the National Consumer Disputes Redressal Commission (NCDRC), and the outcome surprised many: the manufacturer walked free – not because insects weren’t found, but because of two critical procedural and evidentiary gaps in the complaint. This case is a textbook illustration of how consumer disputes are actually decided in India.

The facts of the case 🔗

The respondent (consumer) purchased a Cadbury chocolate from a retail shop – M/s Top Stores in Bangalore – on 9 January 2006. The product had been packed in August 2005 and was within its nine-month consumption period. Upon opening the pack, the consumer discovered worms and fungus inside. Some family members who had consumed portions of the chocolate experienced vomiting sensations. A complaint was promptly filed before the District Consumer Forum against Cadbury India Ltd., the manufacturer.

The District Forum ruled in favour of the consumer and directed Cadbury to pay compensation. Cadbury appealed to the State Commission, which dismissed the appeal. Cadbury then filed a revision petition before the NCDRC – and this is where the outcome changed decisively.

What the NCDRC found 🔗

The National Commission examined the complaint carefully and identified two fatal weaknesses that neither the District Forum nor the State Commission had adequately addressed.

The shopkeeper was not made a party 🔗

The consumer had purchased the chocolate from a specific retail shop, but that shop – the actual seller – was never impleaded as a respondent in the complaint. This is not a minor technicality. Under consumer law, the supply chain matters. A product passes through a manufacturer, a distributor, and a retailer before it reaches the consumer. Each link in this chain is a potential point of contamination, damage, or negligence.

The NCDRC observed that, at the most, this appeared to be a case of deficiency attributable to the seller – the shopkeeper who stored and sold the chocolate – rather than a defect that arose at the manufacturing stage. Since the shopkeeper had not been made a party to the proceedings, there was no opportunity to examine the storage conditions at the retail level or to fix liability on the seller. The Commission held that this omission created an unbridgeable gap in establishing who was actually responsible.

No proof of manufacturing defect 🔗

The second and equally important issue was the burden of proof. Under the Consumer Protection Act, a “defect” is defined as any fault, imperfection, or shortcoming in quality, purity, or standard as required by law. When a consumer alleges a manufacturing defect specifically, they must demonstrate that the defect originated at the factory – not somewhere along the supply or storage chain.

In this case, there was no laboratory test, no expert analysis, and no other credible evidence establishing that the insect infestation occurred during production at Cadbury’s facility. Cadbury, in its defence, argued consistently that it followed stringent manufacturing practices and that infestation of this nature was far more likely to result from poor storage conditions at the retail outlet. The Commission found this argument compelling, particularly because the retailer’s storage practices had never been examined – precisely because the retailer was not part of the case.

With no evidence connecting the worms to the manufacturing process, the complaint against the manufacturer could not be sustained. The NCDRC accepted the revision petition, set aside the orders of the lower forums, and dismissed the complaint. It also noted that if any compensation had already been paid, it should not be recovered from the consumer.

Why the retailer’s role matters so much 🔗

Chocolates are food products that are highly sensitive to storage conditions – temperature, humidity, and proximity to other goods all affect their integrity. Industry experience with Cadbury’s 2003 worm controversy had already demonstrated this vividly: when Maharashtra’s FDA seized Cadbury stocks from its Pune plant, Cadbury’s own defence was that insects entered through improper retail storage, not during manufacturing. The FDA disagreed on that occasion and blamed packaging standards, but the core dispute – where exactly did contamination occur? – remained genuinely contested.

That same contestation sits at the heart of the NCDRC case. When the retailer is excluded from the complaint, the forum cannot assess whether the chocolate was stored beside grain sacks, left in warm conditions, or handled carelessly before sale. The chain of custody becomes invisible, and without it, pinning liability exclusively on the manufacturer is legally untenable.

This is precisely why consumer law in India expects complainants to join all parties who may be responsible. Order 1 Rule 10 of the Civil Procedure Code – applicable in spirit to consumer proceedings – allows a forum to implead necessary parties. When a consumer bypasses the retailer entirely, they essentially deprive the forum of the evidence and the party needed to complete the factual picture.

The legal principles this case establishes 🔗

Several important principles emerge from the NCDRC’s ruling in Cadbury India Ltd. v. L. Niranjan that are relevant to any consumer complaint involving allegedly defective goods.

All parties in the supply chain should be made respondents 🔗

If a consumer buys a product from a shop, both the manufacturer and the retailer should ordinarily be named in the complaint. This gives the forum the complete picture – who manufactured it, who stored it, and in what condition it was sold. Omitting the retailer, as happened here, leaves a significant evidentiary and legal gap.

The complainant bears the burden of proving manufacturing defect 🔗

It is not enough to show that a defect existed at the time the consumer opened the product. Under Section 2(10) of the Consumer Protection Act, 2019 (earlier Section 2(1)(f) of the 1986 Act), a defect means any fault in quality or standard as required by law. To attribute that defect to the manufacturer specifically, the consumer must lead evidence – ideally a laboratory test or expert opinion – showing the defect originated at the production stage. In the absence of such evidence, the claim against the manufacturer fails.

Visible contamination alone may not be sufficient 🔗

An interesting contrast exists between this case and another NCDRC ruling – M/s. Cadbury India Ltd. v. Kanteppa & Anr. (2015) – where the District Forum itself opened the wrapper and observed worms with the naked eye, which was considered sufficient evidence of a manufacturing defect. The Kanteppa case shows that courts can, in appropriate circumstances, treat visual evidence of infestation as adequate proof. But the critical distinction is that in that case, the retailer was a party, and the overall evidentiary record was richer. Where there is no retailer in the case and no lab analysis, visual evidence alone may not suffice.

Vicarious liability has limits 🔗

A later NCDRC decision – Mondelez India Foods Pvt. Ltd. v. Kumaraswamy MR (2024) – affirmed that a manufacturer can carry vicarious liability for a defective product until it reaches the consumer. But in that case, both the manufacturer and the retailer were named, giving the forum full visibility into the supply chain. The principle of vicarious liability is not a shortcut that allows a consumer to sue only the manufacturer while ignoring the retailer entirely.

What consumers must do differently 🔗

This case is a practical lesson. Here is what it means for anyone who discovers a defect in a purchased product and considers filing a consumer complaint:

Preserve the evidence immediately. Do not discard the product, the packaging, or the purchase receipt. If possible, have the defective product tested at an approved laboratory. Under Section 38(2)(c) of the Consumer Protection Act, 2019, the forum can direct that samples be sent to a laboratory – but the consumer should proactively seek this where the defect is not visible to the naked eye.

Name all relevant parties. If you bought the product from a shop, include that shop as a respondent. If you know who the distributor was, consider including them too. A complaint directed only at the manufacturer, without the retailer, leaves the forum unable to examine the most proximate point of potential failure.

Establish the origin of the defect. Your complaint should articulate specifically why you believe the defect is a manufacturing one – whether based on the sealed condition of the packaging, the date of manufacture, lab results, or other indicators. A vague allegation that something was “wrong with the product” is insufficient to make out a manufacturing defect claim.

The broader lesson on product liability in India 🔗

India’s consumer protection framework under the Consumer Protection Act, 2019 is designed to be accessible to ordinary people. The three-tier dispute resolution structure – District Commission, State Commission, and NCDRC – ensures that consumers have a relatively affordable and informal avenue for redress. But accessibility does not mean evidentiary standards are relaxed. Product liability claims, particularly those targeting manufacturers, require a minimum level of evidentiary rigour.

The Cadbury chocolate case illustrates that consumer forums are not simply sympathetic to the weaker party by default. They apply legal principles consistently: the party best placed to bear liability must be before the forum, and the complainant must produce credible evidence linking the defect to the specific respondent’s conduct. When those conditions are not met, even a genuinely aggrieved consumer may not succeed.

For manufacturers, the case also underscores the importance of maintaining clear documentation of their quality control processes. Cadbury’s consistent defence – that its manufacturing standards were compliant with the Food Safety and Standards Act and that contamination most likely occurred post-production – was ultimately accepted by the NCDRC because the consumer could not disprove it. Rigorous internal records and compliance with food safety regulations give manufacturers a credible evidentiary base when facing such complaints.

What do you think? If you discovered a defect in a packaged food item, would you know which parties to name in a consumer complaint – and what evidence to collect before filing? And do you think consumer forums should be more proactive in directing complainants to implead missing but necessary parties, rather than dismissing a complaint on that ground alone?
