Arson under section 169 StGB: setting fire, property damage, danger to people, expert evidence, intent or negligence and defence.
Mag. Christopher Angerer, Rechtsanwalt
Your lawyer for criminal defence
Criminal proceedings are a matter of trust. One lawyer who walks with you from the first consultation through to the trial, everything from one hand.
After a fire, a criminal allegation can arise quickly. Section 169 StGB concerns arson and therefore not only damaged property, but the particular danger of fire for buildings, people and emergency services.
This article explains how fire cause, intent, negligence, property damage and danger are separated and why expert evidence must be examined early.
In fire cases, the precise cause is decisive. Intent, negligence, property damage and danger to people must be assessed separately.

The first assessment depends on the allegation, the file status and upcoming procedural steps.
At the beginning, no spontaneous explanation should be given. The exact allegation, competence, evidence and procedural status must be clarified first.
From a legal perspective, file access is the basis of any further decision.
Photos, messages, expert material, records and witness leads should be preserved in an organised way. Nothing should be deleted, changed or created afterwards.
Early documentation often decides whether an exculpatory alternative remains traceable later.
Before making a statement, it must be clear what is in the file and which points incriminate or exculpate. Silence, partial information and a written statement are different tools.
Which option fits depends on the concrete allegation.
Before a hearing, evidence applications, exculpatory documents, possible restitution and the procedural goal should be clarified.
Those who start structuring only at the hearing often lose important options.
Arson requires a fire event that is legally more than minor damage. Fire object, risk of spread, concrete danger and proof of intent are decisive.
Not every careless act involving fire is automatically arson. The line to property damage or negligent offences depends on the precise sequence and danger situation.
The cause of fire is usually reconstructed through experts, fire brigade reports, trace patterns, electrical installations, fire loads and witness statements. Individual indicators can be ambiguous.
From a legal perspective, it must be checked whether alternative causes were excluded, whether trace preservation was complete and whether a hypothesis is turned into certainty too early.
The mental element is central for defence. Did someone set a fire deliberately, recognise and accept a risk or is only careless handling of a danger source at stake?
Danger to people must also be examined concretely. Location of persons, evacuation, smoke development and time of the fire can strongly influence the legal assessment.
After a house search or summons, affected persons should preserve records, insurance documents, technical inspection reports and their own photos. Statements on the cause of fire should be prepared only after file access.
Damaged items should not be disposed of and later explanations to witnesses or insurers should not be given without knowing the criminal-law position.
The line depends on fire, danger, intent and concrete damage.
| Classification | Überblick point | Evidence question |
|---|---|---|
| Property damage | Damage to another person’s property | What was damaged? |
| Arson | Dangerous fire event | How far could the fire spread? |
| Negligence | Breach of duty without intent | Which duty was breached? |
| Danger to people | Risk to persons | Who was endangered and when? |
Early review separates cause, intent and concrete danger.
Collect photos, reports and technical documents.
Assess traces and expert evidence from the file first.
Trace technical defects and other causes.
No explanation of cause without expert review.
Fire cause first. In arson cases, the technical cause can be more important than the first account. Expert evidence, traces and alternatives must be reviewed completely.
No. Fire cause, intent or negligence, concrete danger and proof are decisive. Damage by fire alone is not automatically enough.
A very large one. Fire cause, spread, technical defects and alternative explanations are often assessed by experts.
Caution is needed. Insurance statements may later become relevant in criminal proceedings. The criminal-law position should be clarified first.
Where the focus is mainly on damaged property.
Where concrete danger without injury is examined.
