Market and consumer offences: false advertising, market manipulation and insider trading

Defence for companies and executives, action for consumer groups · Author: Francisco Javier Martín Porras, criminal lawyer and court expert · SCJE team

Between the consumer infringement and fraud there is a little-known criminal strip: offences against the market and consumers. Advertising with false claims capable of causing serious harm, manipulation of measuring devices, billing for services not rendered or the use of inside information are punished with prison. We defend accused companies and executives, and harmed consumer groups.

In brief. In brief. False advertising: prison of 6 months to 1 year or a fine (art. 282). Fraudulent billing with manipulated meters: prison of 6 months to 1 year and a fine. Stock-market insider trading: up to 6 years in aggravated cases. Corporate criminal liability and immediate reputational damage.

What is at stake

6m-1a
prison or fine for false advertising with serious harm aptitude (art. 282)
6m-6a
for market manipulation and insider trading according to gravity
Art. 288
CP: publication of the judgment and corporate liability

The criminal strip of the market: where the fine ends and prison begins

Articles 281 to 288 of the Criminal Code punish the serious pathologies of the market: withdrawing essential goods to force price alterations (art. 281), advertising with false claims capable of causing serious and manifest harm to consumers (art. 282), falsehood in economic and financial information to investors of listed companies (art. 282 bis), fraudulent billing through manipulated measuring devices (art. 283), the dissemination of false news and operations to manipulate prices, including “pump and dump” schemes with listed crypto-assets (art. 284), and the use or supply of inside information (arts. 285 and 285 bis), closing with access-condition services and the common provisions of art. 288, which orders the publication of the judgment and provides for corporate liability.

Our practice: for accused companies and executives, market expert evidence, metrological expert evidence on meters with chain of custody, and the reconstruction of Chinese walls in insider cases; for harmed consumer groups, prior consumer files that prove knowledge, and the criminal action that multiplies the recoverable liability.

Provision by provision

Market offences, article by article

Art. 281 CP

Withdrawal of essential goods

Withdrawing raw materials or basic-need goods from the market with the intention of forcing supply shortages or price alterations, or seriously harming consumers; aggravated in catastrophe situations. The offence requires withdrawal with that purpose: lawful speculative stockpiling does not fit. Its real application is scarce but revives in crises (masks, fuels): the defence runs through freedom of enterprise and the evidence of the real market.

False advertising

Manufacturers or traders who make false claims or state uncertain characteristics in their advertising, in a way capable of causing serious and manifest harm to consumers, answer with prison of 6 months to 1 year or a fine. The criminal filter is the serious harmful aptitude: tolerated advertising exaggeration remains outside.
In practice

The serious-harm filter

The “serious and manifest harm” filter separates the offence from the consumer sanction: miracle products with health risks, invented financial returns. We defend with market expert evidence (the standard advertising exaggeration of the sector) and we prosecute with the prior consumer files that prove knowledge.
Art. 282 bis CP

Falsehood in investor information

Directors of listed companies who falsify economic and financial information in prospectuses and documents to the market: prison of 1 to 4 years, aggravated if the harm materialises. The prospectus offence requires falsehood with aptitude to attract investors: business optimism is not an offence, the invented figure is. The accounting expert evidence on what was known and when (internal emails, drafts) decides between art. 282 bis and simple business misfortune.
Art. 283 CP

Fraudulent billing

Billing higher amounts through the alteration or manipulation of automatic measuring devices (meters, fuel pumps, scales): prison of 6 months to 1 year and a fine. It requires manipulation of the device, not a simple billing error. The metrological expert examination of the meter (seals, software, history) is the only evidence that matters: we request it intact and with chain of custody from day one.
Art. 284 CP

Price alteration and market manipulation

Disseminating false news, using violence or deceit, or carrying out operations to alter the prices of securities or financial instruments: prison of 6 months to 6 years depending on the case and the benefit, with fines and disqualification. It is the criminal provision of “pump and dump”, also with listed crypto-assets. Informational manipulation requires real aptitude to alter prices: in narrow securities and crypto it is easier than in blue chips. Telegram pump-and-dump cases are already prosecuted under this offence: identifiable channel administrators and promoters have direct criminal exposure.
Arts. 285 and 285 bis CP

Insider trading

The use or supply of stock-market inside information with relevant benefit or harm is punished with prison of 6 months to 6 years according to gravity. It reaches executives, advisers and anyone who obtains it through their professional activity. The information must be specific, unpublished and relevant: market rumours do not offend. The classic defence reconstructs the Chinese wall and the exact moment of knowledge; the prosecution, the metadata of emails and purchase orders: it is an offence of timestamps.
Arts. 286 and 288 CP

Conditional-access services and common provisions

Art. 286 punishes the circumvention of access systems to broadcasting and interactive services: pirate IPTV and decoders still generate cases; the end user rarely answers, the reseller always. Art. 288 orders the publication of the judgment and provides the criminal liability of legal persons with fines and the penalties of art. 33.7.
In practice

Pure reputational risk

Corporate liability and the publication of the judgment turn these offences into pure reputational risk: commercial and financial compliance programmes are the structural defence, and in insider matters the Chinese-wall compliance is both the best prevention and the best defence.

Qualification: the seriousness filters (manifest harm, real aptitude to alter prices, relevance of the information) separate fine from prison

Phase 04

Trial or agreement: corporate liability and publication of the judgment weigh on the strategy; reputational management runs in parallel

Who we assist

Situations where this defence is decisive

📢

Companies accused over their advertising

The criminal filter is the serious and manifest harm: standard sector exaggeration remains an administrative matter. Market expert evidence draws that border.

📈

Executives and advisers in insider investigations

The offence requires specific, unpublished and relevant information: the Chinese wall and the exact moment of knowledge, proved with metadata, decide the case.

⛽

Businesses accused of meter manipulation

Without manipulation of the device there is no offence: technical defects and reading errors are contractual and administrative matters. The metrological expert report deactivates the criminal route.

🛒

Consumer groups harmed by serious practices

Miracle products with health risks or invented returns: the criminal action, built on the prior consumer files, multiplies the recoverable liability.

FAQ

Frequently asked questions on market and consumer offences

When does misleading advertising go from an administrative fine to an offence?
When the claims are false or the characteristics uncertain and they also have the aptitude to cause serious and manifest harm to the consumer: “miracle” products with health risks, invented financial returns. Generic commercial exaggeration remains a consumer sanction. That leap in gravity is the axis of the defence.
Is trading on the stock market with confidential data from my company an offence?
Yes, if the data is inside information and its use obtains a relevant benefit or causes relevant harm (art. 285): up to 6 years in aggravated cases, besides the CNMV sanctions. Whoever recommends or passes on the data also offends. Chinese-wall compliance is the best prevention and the best defence.
My company overbilled because of a defective meter. Is that art. 283?
No, if there was no manipulation: the offence requires altering or interfering with the measuring device. A technical defect or a reading error generates the obligation to refund and, where applicable, an administrative sanction, but not an offence. Proving it with expert evidence deactivates the criminal route.
