Self-Defence: When Can You Shoot at an Intruder in Your Garden?

Imagine: you are a property owner in Sélestat, it is 11 p.m., you hear a noise in your garden. A prowler is trying to climb over the fence. Your heart racing, you grab your shotgun and fire into the air to scare him off. But if you injure the intruder, are you acting in self-defence? The question, more complex than it seems, was decided by the French Supreme Court in 1980. And the answer is not what you might think.

This ruling, handed down over forty years ago, remains highly relevant for all property owners wondering about their rights when faced with an intrusion. Can you protect your garden as you would your house? The French Supreme Court laid down an essential condition: it all depends on the layout of the premises. Explanations follow.

In this case, a property owner had set up a spring-gun – a rifle connected to a wire stretched 20 cm above the ground – to protect his land. A thief triggered it and was injured. The owner was prosecuted for assault. The French Supreme Court had to determine whether this act fell within self-defence. Verdict: no, because the garden was not enclosed within the general curtilage of the house. Analysis follows.

The Facts: A Story Like Many Others

Mr. X, a property owner in Schiltigheim, had had enough of repeated thefts in his garden. His land, which surrounds the house, is enclosed by a hedge and a gate, but the fence is not continuous with the building. To deter intruders, he installs a formidable system: a shotgun fixed to a post, connected by a wire stretched 20 centimetres above the ground. The slightest contact triggers a gunshot and an alarm bell. One evening, a prowler hits the wire, the gun goes off, and the man is wounded in the leg. A complaint for wilful assault follows.

The criminal court convicts Mr. X to a fine and damages. The owner appeals, invoking self-defence. He argues that his device was intended to repel a nocturnal burglary, which is permitted under the former Article 329 of the Criminal Code (now codified as Article 122-5 of the Criminal Code). But the Court of Appeal upholds the conviction. Mr. X appeals to the Supreme Court. The High Court must decide: is a garden separated from the house by a simple fence protected by self-defence?

The Reasoning of the Court — Analysed

The French Supreme Court relies on Article 329 of the Criminal Code (old), which states that "self-defence exists when the action is taken to repel, during the night, the scaling or breaking into a house or inhabited apartment." It clarifies that this text must be read in conjunction with Article 390 of the same code, which defines "inhabited house" as including "its outbuildings, provided they are enclosed within the same curtilage." In other words, to benefit from the presumption of nocturnal self-defence, the garden or outbuilding must be included within the general curtilage of the house, i.e., form a whole with the building. A garden separated by a distinct fence, even if it has its own enclosure, is not considered part of the house.

In this case, Mr. X's garden was not "enclosed within the general curtilage of the house": it was a separate space, enclosed by a hedge and a gate, but without continuity with the house wall. The Court infers that the intrusion into this garden does not constitute "scaling or breaking into an inhabited house" within the meaning of Article 329. Consequently, the spring-gun is not covered by self-defence. Moreover, the Court recalls that installing a mechanical trap (a rifle triggered by a wire) is itself unlawful, because it does not distinguish between a thief and a child or a lost neighbour. The decision thus confirms settled case law: self-defence is a strictly regulated right, which cannot justify automatic and potentially lethal devices.

What This Changes for You — Concrete Implications

For a landlord in Sélestat or Schiltigheim, this decision means that you cannot install a trap, even non-lethal, in your garden if it is not integrated into the curtilage of the house. If your land is separated from your dwelling by a simple fence, you do not benefit from the presumption of self-defence in the event of a nocturnal intrusion. On the other hand, if your garden is adjoining and enclosed by the same wall as the house, you may, subject to conditions, use force to repel a nocturnal burglary – but never an automatic trap.

Example: suppose that in Schiltigheim, a property owner installs a pressurised watering system triggered by a detector, projecting water at 60°C. If an intruder is burned, the owner could be ordered to pay €3,000 to €10,000 in damages, or even more in the event of serious injury. Not to mention legal costs (€2,000 to €5,000). Better to invest in an approved alarm and deterrent lighting.

For a buyer, check the layout of the land: if the garden is "within the curtilage", you will have more leeway to defend yourself. But in any case, avoid traps: they are prohibited, even in the event of proven theft. The law prioritises the protection of human life over property.

Four Tips to Avoid This Type of Dispute

• Never install a mechanical or electrical trap: even if you are a victim of repeated thefts, an automatic device that injures an intruder exposes you to criminal and civil proceedings. Opt for non-violent systems (alarm, camera, lighting).
• Check the configuration of your fence: if your garden is not included in the continuous curtilage of the house, be aware that nocturnal self-defence does not apply. In that case, it is better to reinforce the fence and install a perimeter alarm system.
• In the event of an intrusion, prioritise calling the police: rather than intervening yourself, dial 112. If you are directly threatened, self-defence may be invoked, but only if the threat is immediate and proportionate. A thief who is fleeing does not justify a shot.
• Consult a lawyer before installing a defence system: a property law professional in Strasbourg can advise you on legal solutions adapted to your situation (regulated electric fence, video surveillance, etc.).

This 1980 decision is part of a consistent line. As early as 1955, the French Supreme Court had ruled that self-defence could not be invoked for traps (Crim., 22 June 1955). More recently, in 2018, the Court recalled that installing an unapproved electrified system constituted unlawful violence (Crim., 12 June 2018, no. 17-84.512). The trend is clear: judges are extremely strict regarding means of property defence. They consider that the protection of human life outweighs the protection of material property, even in the event of theft. No legislative change has occurred since 1980 to relax this position. In the future, with the proliferation of connected objects, the courts may be called upon to rule on "intelligent" systems that distinguish a human from an animal, but the prohibition of automatic traps should persist.

Checklist Before Acting

FAQ: 5 Essential Questions

1. Can I shoot a thief in my garden at night? Only if the garden is within the continuous curtilage of the house and you are in immediate danger. A simple theft does not justify a shot.
2. Is a spring-gun allowed if I warn with a sign? No. Any automatic device that can cause injury is prohibited, even with a warning.
3. What if my neighbour installs a trap that injures my child? File a complaint for assault. The neighbour will be criminally prosecuted and may be ordered to pay damages (several thousand euros).
4. Can I use a taser or pepper spray against an intruder? Yes, but only in a situation of immediate and proportionate self-defence. Their use must be strictly necessary.
5. What are the risks if I install an unapproved electric fence? A fine of up to €15,000 and imprisonment in the event of serious injury.
