Ignition

Term and meaning of arson (inbrandsetzen)

In arson (inbrandsetzen) in German criminal law, arson is understood as the intentional, or at least knowingly accepted, causing of a fire to a tangible object. The term is particularly relevant in the context of arson offenses and refers to the specific characteristics and legal consequences of these offenses. Its comprehensive definition and application are primarily found in Sections 306 et seq. of the German Criminal Code (StGB).

Legal classification

Arson is a central element for various arson offenses. It is not sufficient for an object to merely catch fire or be damaged; rather, it is required that the object of the fire is ignited in such a way that it can continue burning independently in essential parts.

Requirements for arson

Object of the act

The object in question must be combustible. The law explicitly mentions, for example, buildings, huts, business premises, technical work equipment, and vehicles. Both immovable and movable inventory can also fall under relevant legislation depending on the specific circumstances.

Act of the offense

Arson is completed as soon as the fire has spread to the object in such a way that a self-sustaining combustion process exists, endangering its substance. It is not sufficient if only an easily removable surface (e.g., wallpaper, paper) burns without the object itself being an active source of fire.

Example: If a curtain is set on fire but the fire does not spread to the window recess or the rest of the apartment, the element of arson under Section 306 StGB may not yet be fulfilled.

Distinction from setting a fire and destruction by fire setting

Arson is to be distinguished from mere fire setting or destruction by fire setting. The latter also includes cases where the object does not burn independently but is destroyed by an attempted arson, for example, by explosions or heavy smoke development.

Elements of the offense and types of arson

Simple arson (§ 306 StGB)

This basic offense concerns the arson of another person’s buildings, huts, business premises, technical installations, and certain other objects. The subjective element requires intent with respect to the act and the object.

Aggravated arson (§ 306a StGB)

Aggravated arson extends criminal protection to inhabited buildings or places where people are regularly present. For this element to be fulfilled, the act of arson must pose a concrete danger to persons.

Especially serious arson (§ 306b StGB)

Here, penalties are increased for cases where people are killed or suffer significant disadvantages.

Arson resulting in death (§ 306c StGB)

If death results from setting a fire, there is a significantly increased penalty.

Attempt, completion, and conclusion

Attempted arson

A punishable attempt under Section 22 StGB requires an immediate step toward fulfilling the offense. This is given, for example, if an accelerant is applied to or ignited on the object, but the fire does not actually break out.

Completion

The offense is completed when the object, in accordance with the legal requirements, burns independently to a substantial extent.

Conclusion

The conclusion occurs once the unlawful arson is completed and there is no further risk of fire.

Legal consequences of arson

Arson against another’s property incurs varying penalties depending on the seriousness of the offense. Punishments range from imprisonment and claims for damages to the possible application of security and rehabilitation measures (e.g., placement in a detoxification facility).

Negligent arson

The offense of negligent arson is governed by Section 306d StGB. Punishability requires that the offender has grossly violated their duty of care and thereby unintentionally caused a fire.

Special areas of concern

Contributory causation and offender’s intent

The question of which participant is responsible for the arson can only be assessed based on the circumstances of each individual case. If a fire is started by spontaneous self-ignition of the object with no human involvement, no criminal arson has occurred.

Withdrawal and active repentance

An effective withdrawal in accordance with Section 24 StGB is excluded after the act of arson has occurred; however, efforts to minimize damage can be taken into account in sentencing.

References and further information

For further study, in addition to the commentaries, a detailed examination of the current case law of the Federal Court of Justice is particularly recommended, as it regularly provides clarification on individual issues relating to arson and arson offenses.


Conclusion: Arson is a legally complex element under German criminal law with far-reaching criminal and civil law consequences. Its precise scope of application and distinction from related offenses are often the subject of judicial interpretation. Precise knowledge of the elements and legal consequences is essential for the assessment of arson cases.

Frequently asked questions

What penalties are imposed for intentional arson under German law?

Intentional arson is governed under German criminal law by Sections 306 et seq. StGB (Penal Code), among others. Depending on the object of the act—for example, buildings, apartments, business premises, or other structures—the law distinguishes between different offenses such as aggravated arson (§ 306a StGB), especially serious arson (§ 306b StGB), or arson resulting in death (§ 306c StGB). The penalty begins at one year of imprisonment (standard penalty) and can, in particularly serious cases, reach up to 15 years. In addition to imprisonment, secondary penalties such as claims for damages by the victim or measures such as preventive detention or an occupational ban may also be imposed. The sentence is also significantly influenced by various aspects—such as intent, endangerment of human life, or exploiting particular vulnerability. Furthermore, the sentence can be influenced by active repentance or voluntary restitution.

Under what conditions is criminal arson deemed to have occurred?

Legally, arson has occurred when an object is ignited so that at least parts of the object, which are essential for its intended use, burn in such a way that they can continue burning on their own, even if the ignition source is removed. Legally, a distinction is made between completed and attempted arson. Mere singeing, smoldering, or sooting does not suffice as long as genuine self-sustained burning does not occur. Additionally, the perpetrator must act intentionally; negligent conduct falls under different statutory provisions (§ 306d StGB). The characteristics of arson are analyzed very precisely in case law and literature, with the specific object and its structural or use-related features always playing a role.

What are the differences between intentional and negligent arson?

The central distinction lies in the subjective element, i.e., the perpetrator’s internal attitude toward the event. Intentional arson exists only if the perpetrator acts knowingly and willingly—they must have at least accepted the ignition process and the spread of the fire. In contrast, negligent arson exists if the perpetrator disregards the required standard of care and thereby negligently causes a fire that affects a particular type of object (§ 306d StGB). Penalties are much milder for negligent arson than for intentional offenses. There are also differences with respect to attempt: negligence cannot be ‘attempted,’ whereas for intent, even the attempt phase is punishable.

How is attempted arson assessed legally?

Attempted arson is also punishable in accordance with Sections 23, 12 StGB if the law provides for a minimum term of imprisonment of one year for the completed offense. This is generally the case for arson offenses. An attempt exists, for example, if the perpetrator has taken steps that directly lead to the ignition of a fire, but the fire has not yet become self-sustaining or is extinguished early. The specific punishability of the attempt depends on the proximity to the fulfillment of the offense and the perpetrator’s intent. Withdrawal from the attempt is possible if the perpetrator voluntarily and timely prevents the arson.

What role does the object play in the offense of arson?

The legal assessment of arson depends significantly on which object is affected. The law recognizes a variety of specially protected objects, particularly buildings, apartments, business premises, motor vehicles, forests, heathland, etc. The protectability of these objects results in various penalty enhancements, as arson involving inhabited buildings poses considerably greater risks to human life and significant property than arson involving other items. It is also decisive for structures whether they are actually intended for permanent human habitation, as additional risks arise in such cases.

Is there criminal liability if arson merely creates a danger but does not cause actual damage?

Yes, for many arson offenses, creating an abstract dangerous situation is sufficient. Actual damage, such as complete destruction of the object, does not necessarily have to occur. Rather, it is sufficient that the object is set on fire or partially destroyed by the act. In addition, certain offenses, such as aggravated arson or arson resulting in death, include aggravating clauses for cases where additional concrete danger to persons or significant property values is realized. These provisions make it clear that the law punishes even the mere creation of a danger and does not wait for the completion of an actual result.

How do courts distinguish the term ‘arson’?

Case law clarifies that characteristic for arson is a self-sustaining fire. Mere singeing or a brief flare-up without a recognizable risk of the object’s complete destruction is not sufficient. Courts examine in each case whether supporting structural components within the structure were affected by the fire, as only these are essential for proper use. In practice, forensic reports, patterns of fire development, and expert opinions are also consulted to classify the specific danger of the fire from a legal perspective. The decisive factor is always the concrete danger presented by the specific object at the time of the incident.
