Environmental offences · Articles 325-340 CP

Environmental offences: two proceedings over the same facts

Criminal defence throughout Spain · offices in Madrid and Alicante

Almost no environmental criminal case begins in court. It begins with an inspection visit, a sample taken from a manhole, a drone flight over a rural plot or a neighbour’s report to SEPRONA. The sanction file and the criminal case walk together over the same facts, and the second feeds on the first.

In brief. Exceeding an authorised limit is not enough: Article 325 requires proof of a risk of substantial damage. And the defence does not begin on the day of the statement: it begins the day you answer the statement of charges, sign an inspection record or hand the inspector a self-monitoring report. All of that is paper, and the paper travels to the criminal file.

Two proceedings over the same facts

From the inspection visit comes a record, from the record a sanction file and, if the instructor considers the facts may amount to an offence, the matter is sent to the Prosecutor’s Office and the administration suspends its file until the criminal courts rule. That has two consequences. When the criminal case begins, a complete file is already on the table: records, analyses, demands, photographs, licences, annual waste declarations and, very often, documents signed by the investigated person or their technician. And much of that material was generated when nobody was thinking about a criminal trial, but about reducing a fine or closing the file quickly.

The prohibition on punishing twice exists, but it does not work as many believe: Article 31 of Law 40/2015 bars sanctioning facts already punished where there is identity of subject, fact and basis. It is common for the sanction to fall on the company for breaching water or waste law while the criminal proceedings are directed against the director or the technical manager: different subjects, and both routes advance.

Scenarios

The situations we see in the province

Art. 325 CP

Industrial discharges to watercourse or sea

Wastewater discharges from footwear, tanning, marble, plastics or food industry into a ravine or the public water domain. The critical point is usually a pipe bypassing the control manhole and the history of prior demands from the river authority.
Art. 325 CP

Discharges to the sewer and the municipal treatment plant

Sustained exceedance of the discharge authorisation limits into the sewerage network, damaging the plant’s biology or the quality of its effluent. Three papers intersect: the municipal ordinance, the discharge authorisation and the self-monitoring reports the company itself submits.
Art. 326 CP

Waste without authorisation

Scrapyards, breakers, end-of-life vehicle managers, collection of used oils or electrical appliances operating without authorisation or beyond it. The classification of the waste as hazardous changes the scale immediately.
Art. 326 CP

Dumps and infill on rural land

Construction and demolition waste discharged on plots, sometimes under the excuse of agricultural infill or levelling. Where fibre cement, asbestos remains or mixed hazardous waste appear, the matter changes scale at once.
Art. 325 CP

Slurry, sludge and burning on farms

Application of slurry or treatment sludge outside authorised conditions, overflowing storage ponds, leachates reaching an irrigation channel, burning of plant remains or greenhouse plastics. In nitrate-vulnerable zones and near protected wetlands the response is much harsher.
Art. 326 bis CP

Dangerous installations and chemicals

Operating installations with dangerous activity or storage of dangerous substances (solvents, glues, industrial acids) in breach of the rules, endangering people or the environment.
Art. 327 CP

Clandestinity, disobedience and falsified data

The penalty is aggravated where the activity runs without authorisation, where express correction or suspension orders were disobeyed, where environmental information was falsified or concealed, where inspection was obstructed, where irreversible deterioration is risked, and where water is extracted illegally in restriction periods.
Art. 328 CP

Corporate criminal liability

The company can be accused alongside the director or the technical manager: a fine and, where applicable, the Article 33.7 consequences: closure, suspension, disqualification from subsidies and public contracting. For many industrial companies that disqualification weighs more than the fine.
Arts. 330 and 331 CP

Protected areas and the negligent form

Seriously damaging the elements that justified the designation of a protected natural area has its own offence, and gross negligence opens the negligent form with the penalty one degree lower.
The two files

How the administrative and criminal routes interact

MomentAdministrative routeCriminal routeThe key point
InspectionRecord and statement of chargesThe record will later be ratified in courtSign recording discrepancies, never in silence
AcknowledgementReduction of the fine for admittingA signed admission travels to the criminal fileDecide with criminal advice, not only financial
RemissionThe file is suspended and sent to the ProsecutorCriminal proceedings openThe definitive signal: act that same day
Double punishmentBarred with identity of subject, fact and basisCompany sanctioned, director prosecuted: both advanceDifferent subjects defeat the ne bis in idem plea
Interim measuresActivity suspension under sector lawClosure and suspension under Art. 33.7 CPFought with proportionality and corrective measures
EvidenceAnalyses and self-monitoringSubstantial-damage aptitude must be provenSampling, chain of custody and receptor medium
RepairRestoration demandsArt. 340: penalty one degree lowerVoluntary repair before trial is the strongest lever
OutcomeFine and restorationPrison, fine, disqualification, corporate penaltiesAcquittal does not necessarily close the administrative file

This overview is indicative; the interaction between the two routes depends on the sector rules and the specific circumstances of each case.

What the courts require

Where these cases are won

The Article 325 offence requires the discharge to cause, or be capable of causing, substantial damage to air, soil or water quality, or to animals or plants. That harmful aptitude must be proven by the prosecution with technical evidence on the receiving medium, the flow, the pollutant load and the persistence. It is the ground where most defences succeed, above all where the exceedance is occasional, falls within analytical uncertainty margins or arose from a documented and reported breakdown. The sampling, its chain of custody and the contradiction of the analyses are the technical heart of the case.

The paper generated in the administrative file is the other battleground: the signed inspection record must be ratified in court by its author and can be examined on everything it asserts; the acknowledgement signed to reduce a fine is not a confession in the strict sense but the prosecution will use it. And repair works: Article 340 allows the penalty one degree lower for whoever voluntarily repairs the damage, and Article 339 lets the court order those same measures. Withdrawing the waste and restoring, documented, is often the most useful thing a client can do.

FAQ

What to know before the first consultation

I have an open sanction file. How do I know if it can end up in a criminal court?
There are fairly reliable signals: the Guardia Civil or SEPRONA appearing in the file and not only the technician; talk of risk to people’s health or damage to the receiving medium rather than mere parameter exceedance; prior unfulfilled demands; hazardous waste or an unauthorised activity; or notice that the file is suspended because the proceedings were sent to the Prosecutor. That last notification is the definitive signal, and it is advisable to act that same day.
Can I be fined administratively and also convicted criminally for the same discharge?
If there is no identity of subject, fact and basis, yes. It is common for the sanction to fall on the company for breaching water or waste law and for the criminal proceedings to target the director or the technical manager: different subjects, and both routes advance.
I signed the inspection record. Does that hurt me in the criminal case?
Signing proves it was delivered and its content known, not that you accepted it. The problem is not the signature but signing without recording discrepancies. At the criminal trial the record must be ratified by its author, who can be examined on everything it asserts: where the sample was taken, the state of the installation, what was photographed and what was not.
I acknowledged responsibility to pay a lower fine. Does that count as a confession?
It is not a confession in the strict sense and does not automatically bind the criminal judge, but it is a document signed by you admitting facts and the prosecution will use it. It can be contextualised: signed to obtain a financial reduction, without criminal-law assistance and without weighing the criminal significance. Frankly, that argument weakens the acknowledgement but does not neutralise it; better to decide with advice beforehand.
I exceeded my discharge authorisation limits. Is that automatically an offence?
No. Exceeding a limit value is an administrative infringement. The Article 325 offence additionally requires the discharge to cause or be capable of causing substantial damage to air, soil, water, animals or plants. The prosecution must prove that aptitude with technical evidence on the receiving medium, flow, load and persistence. It is where most defences succeed, above all with occasional exceedances, analytical uncertainty or a documented breakdown.
Can they close my plant while the case is investigated?
Yes. The final paragraph of Article 33.7 allows the investigating judge to order, as interim measures, the temporary closure of premises, suspension of activities and judicial intervention. To avoid or lift them, corrective measures, updated self-monitoring and the absence of repetition risk are documented and proportionality is argued.
I am the director, but an external technician handles the environmental side. Am I liable anyway?
Not automatically. Your intervention or position of guarantor and the breach of a duty of control must be proven. A real delegation, with budget, decision-making autonomy and documented supervision, is a serious defence argument. A nominal delegation, without the capacity to stop production, is not. And the reverse warning: the technician with effective delegated functions can be investigated precisely for that reason, so the company and the individuals cannot always share a defence.
If I remove the waste and clean up, does it help in the proceedings?
Yes, and it is probably the most useful thing you can do. Article 340 allows the penalty one degree lower for whoever voluntarily repairs the damage, and Article 339 empowers the court to order those same measures. A documented, voluntary and early restoration weighs on the penalty, on the interim measures and on the civil liability.
