Arson and Wildfire Defense Lawyers

Legal Framework of the Arson Offenses

The Spanish Criminal Code devotes a specific title to the arson offenses (Articles 351 to 358). Article 351 CP punishes arson that endangers the life or physical integrity of persons with imprisonment of 10 to 20 years. Where that danger does not concur, the facts are reclassified as criminal damage. Correct classification is therefore decisive.

Wildfires (Art. 352 CP)

Article 352 CP specifically punishes wildfires with imprisonment of 1 to 5 years and a fine. The penalty is aggravated where the fire endangers the life or integrity of persons, or where it reaches special gravity due to its extent or the serious deterioration or destruction of the natural environment. It is one of the areas with the most litigation in the summer months.

Arson by Negligence

Article 358 CP punishes arson caused by gross negligence. It is a very frequent form: agricultural burns that get out of control, negligence in the use of fire or in rural work. The defense focuses on distinguishing gross negligence — criminally relevant — from slight negligence or accident, which fall outside the criminal offense.

Expert Evidence and Cause Investigation

In arson offenses, the expert evidence on the origin and cause of the fire is almost always the decisive element. Fire investigation reports determine the point of origin, the causing agent and possible human intervention. The defense analyzes this expert evidence rigorously, and may submit a party-appointed expert report to challenge its conclusions.

Defense Strategies

The defense is built on the discussion of authorship and the origin of the fire, the distinction between intent and negligence, the delineation between gross and slight negligence, the assessment of the real danger to life and the challenge to the prosecution's expert evidence. Each front may lead to dismissal, reclassification or a relevant reduction of the penalty.

Procedural Stages and the Competent Court

The investigation of a fire offence usually begins with a police report from the Guardia Civil (often its environmental unit, SEPRONA, or the specialist forest-fire investigation teams) or with a complaint from the regional forestry authority. The Investigating Court for the district where the fire occurred conducts the inquiry: on-site inspection of the point of origin, collection of physical traces, witness statements and, above all, the appointment of the experts who will determine cause and origin. Almost everything turns on this stage: a flawed collection of evidence or a broken chain of custody can irreversibly shape the trial outcome.

The trial court is fixed by the penalty. Where the offence does not exceed five years in prison —the basic forest-fire offence of Article 352 CP, and fires posing no danger to life or physical integrity, which Article 351 CP channels to the criminal-damage rules of Article 266 CP— jurisdiction lies with the Criminal Court (Juzgado de lo Penal). Where the penalty may exceed five years —the aggravated forest-fire offence of Article 353 CP, or the Article 351 fire that endangers human life or physical integrity, punishable with ten to twenty years— the case is heard by the Provincial Court (Audiencia Provincial). The National Court has no jurisdiction unless an express statutory connection applies, which is exceptional in these offences.

The investigating judge's initial classification is not binding: an active defence from the outset may have the conduct reclassified from the aggravated to the basic offence, or from an intentional fire to a negligent one, which changes both the competent court and the penalty range. That is why it is essential to intervene before the order transforming the case into abbreviated proceedings or the order opening the oral trial, while it is still possible to propose defence expert evidence and contest how the facts fit the offence.

Limitation of the Offence and the Reporting Period

Limitation is calculated on the maximum penalty for the offence (Article 131 CP), and in fire offences the gap between the various offence types is stark. The Article 351 CP fire that endangers human life or integrity, punishable with up to twenty years in prison, becomes time-barred after twenty years —one of the longest periods in the Code. The aggravated forest fire of Article 353, carrying up to six years, becomes time-barred after ten years. The basic offence of Article 352, whose penalty does not exceed five years, becomes time-barred after five years.

It is worth setting out the statutory anchor to avoid common errors: penalties of up to five years become time-barred after five years; those over five and up to ten, after ten; those over ten and up to fifteen, after fifteen; and those over fifteen, after twenty. There is no intermediate three-year band. Time runs from the day the offence was completed —that is, when the fire was lit— and is interrupted when proceedings are formally directed against the person under investigation.

In cases of grossly negligent fire under Article 358 CP, the penalty is one degree lower than that of the corresponding intentional offence, so the limitation period is reduced accordingly and may drop to five years in cases that, if intentional, would be time-barred after ten. Pinpointing the date the fire started, the date of the first valid charge and the penalty applicable in the abstract is one of the first tasks of the defence, because a well-founded limitation defence closes the case without reaching the merits.

Civil Liability, Environmental Restoration and Corporate Criminal Liability

A conviction for a fire offence carries civil liability that, in forest fires, can far exceed the criminal fine itself. Compensation is not limited to timber or the market value of what burned: the cost of extinguishing the fire, the loss of woodland and soil, ecosystem regeneration, damage to infrastructure and, where applicable, lost profits of affected operations are all assessed. Courts accept that reparation may include the restoration of the damaged environment, not merely a sum of money, which requires each item of the damage report to be technically contested.

Where the fire is linked to a business activity —waste management, industrial-scale agricultural burning, works or installations that generate risk— corporate criminal liability may come into play. In the field of environmental offences, Article 328 CP provides specific penalties for legal persons under the Article 31 bis regime: fines calculated by reference to the individual's penalty or to the harm caused, and potentially dissolution, suspension of activities, closure of premises or disqualification from subsidies and public contracting.

Against that exposure, the existence and genuine effectiveness of a criminal compliance programme is decisive. A sound organisation and management model —with a fire-risk map, burning protocols and a supervisory body with real autonomy— can operate as a full defence or a mitigating factor for the company. The defence must show not only that the programme existed on paper but that it was actually applied; a merely cosmetic compliance scheme offers no protection and may even worsen the entity's procedural position.

Plea Agreements, Mitigation and Suspension of Sentence

Not every fire prosecution ends in trial. Where the prosecution evidence is strong, a well-negotiated plea agreement (conformidad) can reduce the penalty sought and, above all, structure the civil liability in a way the defendant can bear. A plea requires a cool assessment of the expert evidence and of the true penalty range; accepting or rejecting it is not a matter of convenience but of strategy, and the decision must be taken with the full cause-and-origin report on the table.

Mitigating and aggravating circumstances weigh heavily in these offences. Repairing the harm before trial —paying or assuming the cost of extinguishing and restoration— is a powerful mitigating factor, especially relevant where the loss is of great economic and ecological value. Confession, cooperation with the investigation and undue delay in the proceedings can also operate as mitigation. On the other side, in forest fires Article 353 itself turns into an aggravation the profit motive, harm to protected areas or to zones near inhabited places, and weather conditions creating a high risk of spread.

Suspension of a custodial sentence (Article 80 CP) is available for sentences of no more than two years for first-time offenders, which brings within reach many basic-type forest fires and cases of gross negligence under Article 358 CP, but excludes the Article 351 fire that endangers people, whose minimum penalty is very high. Planning from the outset the repair of the harm, the offender's record and the individualisation of the sentence allows the court to be presented with a realistic suspension proposal, avoiding imprisonment where the law permits.
