Estragos (Mass Destruction) Defence Lawyers

The offence of estragos (mass destruction) punishes causing large-scale destruction that creates a danger to the life or safety of people. Regulated in Articles 346 and 347 of the Criminal Code (CP), it is one of the most serious endangerment offences in Spanish criminal law, with penalties reaching 20 years' imprisonment in its intentional form. It protects both collective safety and the integrity of people against man-made catastrophic events.

Typical Conduct

Art. 346 CP lists the means of commission: causing destruction by fire, explosion, collapse, flooding or by tampering with machinery at an installation. The central requirement is that the destruction create a general danger to the life or safety of people. It is not necessary that anyone is actually injured or killed; it is enough that a situation of risk was objectively created. Where there are victims, estragos concurs with the corresponding offences of homicide or injury.

Penalties by Modality

Intentional estragos carries prison of 10 to 20 years, one of the highest penalties in the Criminal Code. Negligent estragos (Art. 347 CP), caused by gross negligence —such as a collapse due to construction defects or an industrial explosion caused by poor maintenance— is punished with prison of 1 to 4 years. Where the negligence is professional, special disqualification from the relevant profession or trade for 3 to 6 years is added.

Estragos by Professional Negligence

The negligent form is particularly relevant in regulated sectors: construction (collapses due to structural defects), the chemical industry (toxic leaks or explosions from breached protocols), mining (gallery collapses), pyrotechnics (explosions in stores of flammable products), energy (incidents at electrical installations or gas pipelines) and hospitality (fires in premises with deficient evacuation). Liability falls on the professionals who breached the applicable technical safety rules.

Distinction from Related Crimes

Estragos is distinguished from related offences: from arson (Arts. 351-358 CP), which focuses on the spread of fire rather than structural destruction; from homicide, which requires that someone actually dies; from criminal damage (Art. 263 CP), which protects property without requiring danger to people; and from terrorism (Art. 573 CP), which adds an ideological, religious or political purpose. Intentional estragos is both a result offence (the destruction) and an endangerment offence (the risk to people).

Corporate Liability

Where estragos occurs in a corporate setting (an industrial explosion, the collapse of a building site), the legal entity may be convicted if the catastrophe stemmed from organisational failings or breaches of industrial safety rules. Sanctions on the company include fines, judicial intervention, suspension of activities and, in serious cases, dissolution. The existence of an effective risk-prevention programme is relevant as a mitigating circumstance.

Forensic Investigation

Investigating estragos requires multidisciplinary technical expert evidence: structural engineers (collapses), forensic chemists (explosions), fire investigators (fires) and forensic doctors for the victims. The Forensic Police and criminalistics laboratories analyse the debris to determine the cause of the destruction (explosive, negligence, spontaneous combustion). The chain of custody of the remains of the incident is critical to the validity of the evidence.

Defence Strategies

The defence may be built by showing: that the destruction was accidental and without negligence (unforeseeable event, force majeure); that all applicable safety rules were complied with (industrial regulations, building code); that the risk to people was non-existent or insignificant; that the chain of causation was broken by the intervention of a third party; or that the prosecution's expert report suffers from methodological flaws. Recharacterising intentional estragos as the negligent form, with markedly lower penalties, is often the central objective. We act before the Investigating Courts, the Provincial Courts and, where appropriate, before specialised courts.

Procedural Stages and the Competent Court

A criminal case for the offence of causing havoc (estragos) almost always begins with the urgent intervention of emergency services and the judicial police, who secure the scene, set a perimeter and preserve the point of origin of the explosion, collapse or flooding. The investigative phase is led by the Investigating Court of the district where the events occurred: it orders the on-site inspection, gathers fire-service and technical reports, takes statements from witnesses and injured parties and, where appropriate, adopts personal or property precautionary measures. The defence should be involved from the very first moment, because the inspection record and the chain of custody of the debris shape all subsequent evidence.

Jurisdiction over the trial is determined by the penalty. Where the facts are reclassified into forms carrying a prison sentence not exceeding five years, the Criminal Court (Juzgado de lo Penal) hears the case. For estragos under Article 346 involving danger to life (ten to twenty years' imprisonment), or for the more serious forms of Article 346 without that danger (four to eight years, which exceeds the five-year threshold), the Provincial Court (Audiencia Provincial) tries the matter. A common misconception should be dispelled: the National Court (Audiencia Nacional) is not competent merely because the havoc is severe; it would be so only where an express statutory connection applies, such as a terrorist purpose, which is a different offence.

Correctly identifying the competent court is no minor technicality. It governs the appeal regime, the composition of the tribunal and the time limits. A charge inflated at the outset by the prosecution may drag the case to the Provincial Court when the facts, properly analysed, fit a lesser form. Raising the question of jurisdiction at the appropriate procedural moment, or seeking reclassification to criminal damage under Article 266 or to the negligent figure of Article 347, can return the proceedings to their proper channel and rebalance the position of the accused.

Limitation Period for the Offence of Estragos

Limitation is governed by Article 131 of the Criminal Code, which sets the periods according to the maximum penalty attached to the offence. Following the reform introduced by Organic Law 5/2010, the old three-year bracket no longer exists: the minimum period is five years for offences whose maximum penalty does not exceed five years. From there, the brackets are ten years (maximum penalty over five and up to ten), fifteen years (over ten and up to fifteen) and twenty years where the maximum penalty exceeds fifteen years' imprisonment.

In the offence of estragos this scale has very significant consequences. Article 346 with danger to life carries ten to twenty years' imprisonment; because its maximum penalty exceeds fifteen years, it becomes time-barred after twenty years. This is a long period worth bearing in mind: criminal liability for these facts can be pursued for two decades. The form without danger to life (four to eight years' imprisonment) becomes time-barred after ten years, and estragos by gross negligence under Article 347 (one to four years' imprisonment) after five years.

The clock starts on the day the offence was committed and is interrupted only when the proceedings are effectively directed against the specific person, not by mere undefined enquiries. In complex incidents, where the cause of the fire or the blast takes time to establish, the debate over the dies a quo and over which acts genuinely interrupt the period carries great weight. The defence must rigorously verify the period applicable to the true classification of the facts, because a charge under the most serious offence may improperly carry a limitation period that would correspond only to that form.

Civil Liability, Restitution and Repair of the Harm

Every offence of estragos generates, alongside criminal liability, civil liability covering restitution, repair of the harm and compensation for the material and moral damage caused. Where the destruction affects public infrastructure, transport routes, essential supplies or third-party property, the quantification of the harm may be very high and requires a contested expert valuation of the cost of replacement or reconstruction, rather than mere acceptance of the figure proposed by the prosecution or the injured entity.

Here the defence has technical ground to work on. It is appropriate to challenge the real scope of the damage attributable to the conduct, to separate pre-existing deterioration, to discount improvements or overvaluations and to specify which items correspond to actual repair and which to a loss of profit that must be proven. In incidents with environmental or structural impact, an independent report is advisable to define rigorously the perimeter of recoverable harm against loosely supported global estimates.

Repairing the harm before trial also has a mitigating effect. Article 21.5 of the Criminal Code provides for the mitigating circumstance of the offender having repaired the harm caused to the victim, or having reduced its effects, at any stage of the proceedings before the oral trial. In offences carrying penalties as high as Article 346, a serious and documented repair, whether full or partial, can have a decisive influence on the individualisation of the sentence and, where appropriate, on negotiating a plea agreement.

Plea Agreements, Mitigating Factors and Suspension of Sentence

Not every estragos case need reach trial on the harshest terms. Where the evidence is strong or the classification is reduced to a less serious form, it may be more beneficial for the accused to explore a plea agreement (conformidad). A plea agreement requires a cool assessment of risk: weighing the sentence the prosecution is willing to accept, the presence of mitigating factors and the likely outcome of an uncertain trial. In estragos by negligence under Article 347, or in intentional forms without danger to life, a well-negotiated agreement recognising mitigating factors can place the sentence within reasonable bands.

The individualisation of the sentence depends on the modifying circumstances. Alongside repair of the harm (Article 21.5), consideration may be given to confession of the offence before the person knows that proceedings are directed against them (Article 21.4), extraordinary and undue delay in the process or, in cases of negligence, the degree of the lack of diligence and the foreseeability of the result. The line between gross negligence under Article 347 and less serious negligence, or between conditional intent and mere negligence, is often the real technical battleground of the case.

Suspension of the execution of a custodial sentence, regulated in Articles 80 and following, generally applies only where the imposed sentence does not exceed two years. In estragos under Article 346, with much higher penalties, ordinary suspension is unavailable, which reinforces the importance of contesting the classification and pursuing the correct form. By contrast, in estragos by gross negligence under Article 347, a sentence finally fixed in its lower band may open the door to suspension, especially where mitigating factors and repair of the harm concur and the person has no prior record.
