A German court has ruled that Mondelez International misled consumers by reducing the weight of its Milka chocolate bars without clearly indicating the change on packaging. The decision, handed down by the Frankfurt Regional Court, found that the company’s practice of keeping the same price while shrinking the product from 300g to 270g violated German unfair competition laws. The ruling highlights a growing judicial scrutiny of shrinkflation across Europe, but it is the United Kingdom that has established a more robust framework for such cases, consumer law experts say.

The court specifically criticised Mondelez for failing to sufficiently inform shoppers of the weight reduction, which occurred in 2020. The judge noted that the packaging omitted any reference to the change, leaving consumers to discover the smaller bar only after purchase. This contravenes German standards requiring transparent communication about product alterations that affect value. The ruling could set a precedent for similar cases pending against other food manufacturers in Germany.

However, legal analysts argue that the UK already provides clearer protections. Under the Consumer Protection from Unfair Trading Regulations 2008 and the Consumer Rights Act 2015, British retailers and manufacturers are required to ensure that packaging does not deceive consumers. The Competition and Markets Authority (CMA) has actively pursued enforcement actions against shrinkflation practices. For instance, in 2022, the CMA secured undertakings from several major brands to improve labelling when product sizes are reduced.

Dr Eleanor Shaw, a consumer law specialist at the University of Cambridge, noted: "The German ruling reinforces the principle that shrinkflation without adequate notice is unacceptable. But the UK has gone further by integrating this into broader unfair commercial practices law, making it easier for regulators to intervene proactively rather than rely on case-by-case litigation."

The British approach is also more comprehensive because it covers all forms of misleading omissions, including failure to disclose negative changes. The German court decision, while important, is limited to the specific facts and may not automatically apply to other products or companies without further legal challenges.

The Milka case began when a German consumer group, Verbraucherzentrale Baden-Württemberg, sued Mondelez for deceptive packaging. The court ordered the company to cease selling the reduced bars without proper notice and to pay damages. Mondelez has indicated it may appeal the ruling.

For UK consumers, the message is clear: shrinkflation remains a concern, but the legal tools to combat it are more developed. The CMA's guidance on pricing practices explicitly warns against reducing quantity without explaining the change, and the Groceries Code Adjudicator monitors similar issues in the supermarket sector. The UK's departure from the EU has not weakened these protections; indeed, the retained EU law framework has been adapted to maintain high standards.

The German ruling may encourage further litigation across Europe, but for now, the UK stands as a model for balancing corporate interests with consumer rights. As inflation persists, the courts will likely continue to grapple with shrinkflation, and the British precedent of clear disclosure offers a practical solution that the German decision now reinforces.
