Criminal Defence for Market and Consumer Crimes

What Market and Consumer Crimes Are

Chapter XI of Title XIII of the Spanish Criminal Code groups the offenses relating to the market and consumers (Arts. 278 to 286). These are conducts attacking the proper functioning of the market, the free formation of prices and the rights of consumers and investors. The chapter includes the discovery and disclosure of trade secrets (Arts. 278-280), which has dedicated treatment, and a set of figures protecting confidence in the market: misleading advertising (Art. 282), falsifying the financial information of securities-issuing companies (Art. 282 bis), fraudulent invoicing (Art. 283), market manipulation (Art. 284), insider dealing (Art. 285) and unlawful access to broadcasting services (Art. 286).

These are technically demanding proceedings: the evidence rests on economic expert reports and frequently coexists with administrative files of the Spanish National Securities Market Commission (CNMV).

Misleading Advertising and Fraudulent Invoicing

Article 282 CP punishes manufacturers or traders who, in their offers or advertising of products or services, make false claims or state untrue characteristics such as to cause serious and manifest harm to consumers. The penalty is six months to one year in prison or a fine of twelve to twenty-four months. The defense focuses on distinguishing the punishable conduct from the mere advertising exaggeration tolerated in commerce, and on analyzing the real capacity of the information to cause that serious harm.

Article 283 CP punishes fraudulent invoicing: invoicing higher amounts for products or services whose cost is measured by automatic devices, by altering or manipulating them. The penalty is six months to one year in prison and a fine of six to eighteen months.

Market Manipulation (Art. 284 CP)

Article 284 CP represses various forms of market manipulation: altering the prices that should result from free competition by using violence, threat, deception or any other artifice; spreading news or rumors with false or misleading economic data; and carrying out transactions or orders that give false signals about the supply, demand or price of a financial instrument, or that secure its price at an abnormal or artificial level. The penalty is six months to six years in prison, a fine and special disqualification from intervening in the financial market for two to five years.

Insider Dealing (Art. 285 CP)

Article 285 CP punishes anyone who, directly or indirectly, carries out transactions on a financial instrument —acquisition, transfer, assignment, or cancellation or modification of orders— using inside information to which they had reserved access, or recommends its use to a third party, provided one of the circumstances set out in the provision concurs. The penalty is six months to six years in prison, a fine and special disqualification from the profession or activity for two to five years. Articles 285 bis and following provide for further modalities and aggravations. The defense requires precisely delimiting which information qualified as inside information and whether the investment decision was actually based on it.

Defense Strategy

Defense of these offenses rests on three pillars. First, economic expert evidence: reconstructing the transactions and establishing the true origin of the decisions. Second, the analysis of the causal link between the conduct and the price alteration or the benefit obtained. Third, coordination with the CNMV file, because the administrative and criminal qualifications may not coincide and the non bis in idem principle operates with nuances. In consumer crimes, the actual extent of the harm and the possibility of repairing it are also assessed.

Procedural Stages and the Competent Court

As a general rule, these offences are investigated by the Investigating Courts of the place where the conduct occurs, through the abbreviated procedure where the penalty does not exceed nine years, or through the ordinary procedure for the most serious forms. The investigation usually begins with a complaint from a consumer, an association, the National Markets and Competition Commission or the National Securities Market Commission, or with a formal accusation by the injured party. During this phase the key steps are taken: documentary requests, expert reports and, where appropriate, precautionary measures to secure assets.

The scope of the Audiencia Nacional is limited: in smuggling it hears only cases concerning defence material or dual-use goods (Art. 65 LOPJ), and market and consumer offences are, as a rule, tried before the ordinary territorial criminal jurisdiction, even where they have effects across several provinces. Identifying the competent court from the outset prevents nullity for lack of objective or territorial jurisdiction and allows the defence to be argued before the correct tribunal, which is decisive in cases with cross-border ramifications or complex corporate connections.

After the investigation, the procedure moves to the intermediate stage, where dismissal or the opening of trial is decided, and from there to the trial itself. Each stage offers defence opportunities: challenging the strength of the indicia, disputing the legal classification, opposing pre-trial detention or asset measures, and excluding evidence obtained in breach of fundamental rights. Early and technical intervention shapes the outcome of the entire proceedings.

Economic and Documentary Expert Evidence

In offences against the market and consumers the evidentiary battle is essentially documentary and expert-based. The core of the debate revolves around accounting records, commercial registry entries, emails, contracts, advertising materials, invoicing and securities transactions. The prosecution seeks to reconstruct a narrative of deception, price distortion or misuse of confidential information from this material; the defence, in turn, must analyse it rigorously to show alternative readings, errors of attribution or the absence of the required mental element of the offence.

Accounting and economic expert evidence is decisive in quantifying the harm, verifying the calculation of the profit allegedly obtained, or showing that the prosecution's figures do not hold up. In misleading advertising, technical reports may be relevant and, where the dispute concerns misleading consumers about a product's features or a trademark, specialist opinions or reports from the Spanish Patent and Trademark Office may carry weight. In market manipulation and insider dealing, expert evidence on price formation, traded volumes and the chronology of operations helps to distinguish a legitimate investment decision from criminally relevant conduct.

A sound defence questions the chain of custody of the documentation, the methodology of the prosecution's expert and the representativeness of the data used. Submitting a well-grounded defence expert report, requesting clarifications at trial and highlighting the margins of technical uncertainty are usually effective levers to introduce the reasonable doubt that an acquittal requires or, where appropriate, to steer the classification towards a less serious offence.

Limitation Periods for the Offence

Limitation is a first-rank defence avenue in this field, because many of these conducts are discovered years after they occur. Article 131 of the Criminal Code sets the periods according to the maximum penalty attached to the offence, and in this group there is no three-year bracket: the relevant periods are one, five and ten years.

For misleading advertising under Article 282 and fraudulent invoicing under Article 283, whose maximum penalty does not exceed five years, the offence becomes time-barred after five years. The diversion of raw materials under Article 281 follows the same logic depending on the specific penalty attached to the charged form. By contrast, in market manipulation under Article 284 and insider dealing under Article 285, where the applicable form carries a maximum penalty above five years, the limitation period rises to ten years. If the conduct were downgraded to a minor offence punished only by a fine with the standing of a petty offence, the period would be one year.

The clock generally starts running once the act is completed, and is interrupted when proceedings are formally directed against the person under investigation, restarting if the case stalls. Calculating the start date precisely, identifying the maximum penalty actually applicable to the specific form, and detecting relevant procedural stoppages make it possible to raise limitation as a preliminary issue or as grounds for dismissal, with a potentially decisive impact on the case.

The Boundary with Administrative, Competition and Civil Routes

Not every market breach is a crime. There is a strong boundary between criminal reproach and the administrative, regulatory, commercial or civil response. Unlawful advertising, unfair commercial practices and competition infringements have their own regimes before bodies such as the National Markets and Competition Commission or the National Securities Market Commission, with their own proceedings and penalties. Criminal law should intervene only against the most serious conduct, as required by the principles of minimum intervention and last resort.

This distinction is fertile ground for the defence. Many conducts reported as crimes actually fit an administrative infringement or a purely commercial or consumer dispute that should be resolved in its natural jurisdiction. Demonstrating the absence of the seriousness, the capacity to cause relevant harm, or the specific intent the offence demands supports the argument that the conduct is not criminal and should be redirected to a non-criminal route, avoiding a conviction.

The non bis in idem principle also matters: no one may be punished twice for the same facts on the same grounds. Where there is already an administrative file or a decision by a regulator on the same conduct, the possible breach of this principle should be analysed. A defence that masters this boundary often achieves a resolution outside the criminal process, with far less harmful consequences for the individual or the company.

Corporate Criminal Liability and Compliance

The conduct under Article 286 bis, on corruption in business, and much of this group of offences may give rise to the criminal liability of the company itself under Article 31 bis of the Criminal Code. A legal person is liable for offences committed in its name or on its behalf and for its direct or indirect benefit, by those who manage it or by those under its authority where due control has been lacking. This opens a dual dimension of defence: that of the individuals involved and that of the entity.

The compliance programme is the central tool for both prevention and defence. A suitable organisation and management model, adopted and effectively implemented before the act, with a supervisory body endowed with autonomy and with operational reporting channels, can lead to exemption or at least to a significant mitigation of the company's liability. Demonstrating that the programme existed, worked, and was fraudulently circumvented by the individual offender is a decisive line of argument.

In corporate defence it is advisable to review the risk map, the traceability of decisions and the measures taken after detecting the conduct, such as internal investigations, dismissals or reinforced controls. The mitigating circumstances available to legal persons, including cooperation by providing new and decisive evidence or repairing the harm before trial, should also be assessed. A coordinated strategy that clearly separates the position of the entity from that of the individuals prevents the defence of one from harming the other.
