Differences Between State of Necessity (Compulsion) and Self-Defense

In criminal law, for a person to be punished, it is not enough for them to have committed an act that fits the type of crime; that act must also be unlawful and culpable . Self-defense and necessity are two important institutions that can eliminate a defendant's criminal responsibility within this framework. In practice, however, these two concepts are often confused, and erroneous classifications can lead to serious losses of rights in both the investigation and prosecution phases.

1. What is Self-Defense?

Self-defense, in its simplest terms, the necessary and proportionate resistance shown to repel an ongoing or imminent unlawful attack. In the Turkish Penal Code, self-defense a justification for lawfulness . This means that when the conditions are met, the act committed is no longer considered unlawful; the person as if they had not committed a crime at all .

1.1. Conditions for Legitimate Self-Defense

The main requirements accepted in practice and in doctrine are as follows:

It must be an unjustified attack
- The attack must be unlawful. For example, self-defense cannot be invoked when a police officer uses force lawfully.
- An attack can be carried out by a human; however, in some cases, even an animal attack may constitute legitimate self-defense against the person who provoked the animal.
The attack has happened, is certain to happen, or must be ongoing
- The limits of legitimate self-defense against a threat that has not yet begun, but is only a possibility, are quite narrow.
- If the attack has ended, it is no longer a matter of self-defense, but of revenge ; in this case, the act constitutes a crime
Defense should be mandatory
- If the perpetrator has no other way to escape the attack, self-defense is considered necessary.
- For example, seriously injuring an attacker when there is an opportunity to escape may not always be considered self-defense.
There must be proportionality between defense and attack
- The ratio does not imply a one-to-one equality between the means; factors such as the severity of the attack, the means used, the time, and the location are evaluated as a whole.
- While kicking someone who is approaching you with a knife is often considered proportionate, killing them by shooting them with a gun doesn't automatically qualify as self-defense in every situation.
Defensive intent
- The perpetrator's action must be aimed at repelling the attack. If the action is taken solely with the intention of harming the attacker, it can be argued that the limits of legitimate self-defense have been exceeded.

1.2. Consequences of Self-Defense

When the conditions for legitimate self-defense are met:

The act becomes lawful.
The perpetrator should be acquitted
As a rule, no liability for damages arises because the action in question was lawful.

Therefore self-defenseis one of the strongest grounds for legal justification, providing the most effective protection for the accused.

2. What is a State of Necessity (Compulsion)?

In practice, the institution commonly referred to as "state of necessity" is regulated under the heading "state of compulsion" in the Turkish Penal Code. A state of compulsion refers to a situation where a person, faced with a grave and imminent danger and having no other means of escape, attempts to escape that danger with the least possible harm

2.1. Conditions for Necessity

The key elements regarding the state of necessity (compulsion) are as follows:

There must be a serious and imminent danger
- The danger must be both serious (i.e., threatening a significant legal value) and certain (definitely or very imminent).
- This danger can often arise from non-human sources: natural disasters, fires, animal attacks, technical malfunctions, etc.
The danger must not have been deliberately created by the perpetrator
- If a person has deliberately put themselves in danger, it becomes difficult for them to rely on a state of necessity.
- However, even in cases where dangers arise due to negligent behavior, the necessity of action can be debated if the conditions are right.
There must be no other way to escape the danger
- If the perpetrator has the option of eliminating the danger with less drastic measures, they cannot resist the urge.
- For example, instead of leaving your own flooded house, breaking open a neighbor's locked car could be considered a necessity if there is no other way out.
There must be a reasonable balance between the value being protected and the value being sacrificed
- In cases of necessity, the typical scenario is that a lesser interest (e.g., property) is harmed in order to protect a greater legal value (e.g., a person's life).
- Sacrificing a higher value to preserve a lower value is not considered a necessity.

2.2. Legal Nature and Consequences of the State of Necessity

The nature of the state of necessity is debated in legal doctrine; according to most views:

The state of necessity a reason that negates culpability .
Some argue that, under certain circumstances, it can also be considered a justification for legality.

In conclusion:

The perpetrator may not be held criminally responsible
However, liability for compensation may arise towards the injured third party
The Turkish Code of Obligations also contains special provisions regarding compensation for damages caused under duress.

3. Key Differences Between State of Necessity and Self-Defense

While both institutions have the potential to eliminate the perpetrator's criminal responsibility, the differences between necessity and self-defense are quite distinct. A good understanding of these differences is essential for accurate classification in practice.

3.1. Distinguishing Between Attack and Threat

In self-defense:
- an "unjustified attack" .
- The perpetrator acts directly against the attacker or the person who carried out the attack.
- The attack is mostly human-caused (knife attack, gunfire, punching, etc.).
In case of necessity:
- a "danger" involved; this danger does not always stem from a human attack.
- The danger may arise from fire, earthquake, sudden illness, technical malfunction, animal attack, or other non-human causes.
- The perpetrator interferes not with the cause that created the danger, but often with the legal standing of an innocent third party

In short, legitimate self-defense is a response to an attack, while necessity is a response to a threat.

3.2. Against Whom is the Action Taken?

In self-defense:
- The target is often the attacker himself.
- The person resists their attacker, causing harm to their physical integrity or property.
In case of necessity:
- A person may damage the property or rights of an innocent third party in order to eliminate a danger
- For example, breaking down a neighbor's door to escape a fire is a classic example of this.

In this respect, while in cases of necessity the injured party is often a third party who is not at fault , in self-defense the injured party is the wrongful aggressor.

3.3. Legal Nature and Liability for Damages

Self-defense:
- a legal justification.
- Since the act is deemed lawful, as a rule, no criminal or civil liability arises.
- Harm inflicted on the aggressor is considered lawful.
State of necessity:
- , according to the prevailing view, negates culpability.
- The perpetrator may not be held criminally liable; however, obligated to pay compensation .
- Because in cases of necessity, the illegality may not be completely eliminated; only the perpetrator's culpability may be reduced or eliminated.

This difference is extremely important , especially in insurance, compensation claims, and subrogation proceedings

3.4. Balance of Values and Proportion

The essence of legitimate self-defense is to defend "to the extent necessary to neutralize the attack" ; a relative balance is sought between attack and defense .
In cases of necessity, a less important value has to be sacrificed to protect a more important legal value.
- For example, breaking someone else's car window to save a person's life.

At this point, the differences between necessity and self-defense , a "comparison of values" is more prominent, while "the severity of the attack and the proportionality of the defense" come to the forefront in self-defense.

4. Example Scenarios from the Application

To better understand the concepts, let's briefly look at two examples:

4.1. Example of Self-Defense

Person A attacks Person B with a knife, lunging towards their chest. Person B has no chance to escape; B grabs a chair and hits A on the head, stopping the attack. A is injured.

There is an unjust and ongoing attack here .
B's defense is necessary and is aimed at neutralizing the attack.
The tools used are not disproportionate.

In this incident, B's action of legitimate self-defense .

4.2. Example of a State of Necessity

A massive flood occurs at midnight. C is trapped in her house with her young child. The child is in danger of drowning. C breaks the window of the neighboring summer house, enters, and escapes the flood by going upstairs. The homeowner is out of town and is not at fault in the incident.

There is a serious and imminent danger here (flooding, risk of drowning).
C has no other option for salvation.
C damaged her neighbor's property in order to save her own life and the life of her child

This incident is a typical example of a situation of necessity (compulsion) . C may not be held criminally liable; however, the neighbor may be liable for compensation for the damaged glass.

5. Points to Consider During Investigation and Prosecution

For prosecutors, judges, and defense lawyers the distinction between necessity and self-defenseis critically important, both in terms of the nature of the crime and the penalty. Some points to consider in practice are as follows:

The chronological order of events must be detailed; it must be clarified when the attack or threat began and ended.
The source of the attack (human, natural event, technical malfunction, etc.) must be determined to identify the target institution.
Witness statements, camera footage, and expert reports must be used to substantiate the severity of the attack and the proportionality of the defense.
In cases of necessity , a value balance analysis should be performed by comparing who has suffered the damage, the value of the property or right, and the legal value being protected
In cases of self-defense, the legal justification should be emphasized as much as possible; where necessary, a reason that negates culpability .

6. Frequently Asked Questions

6.1. Can self-defense and necessity be applied simultaneously?

In some complex situations, the criteria for both institutions may be debatable; however, the nature of the event usually favors one. Self-defense is more appropriate if there is a reaction against an aggressor, while necessity is more suitable if there is interference with a third party's rights due to a non-human threat .

6.2. Is compensation always paid in cases of necessity?

Each case is evaluated on its own merits; however, the general rule is that compensation should be awarded for the damage suffered by an innocent third party. This shows that while a state of necessity removes criminal liability, it does not completely eliminate civil liability .

6.3. How is the claim of self-defense proven?

Self-defense often relies on the statement of the defendant who was present at the scene; however, camera recordings, witness testimonies, forensic reports, and crime scene investigations . Proportionality and the wrongfulness of the attack must be substantiated with this evidence.

Conclusion

The state of necessity (compulsion) and self-defenseare two fundamental institutions in Turkish criminal law that can eliminate or reduce the defendant's liability.

Self-defense is a necessary and proportionate response to an unlawful attack , and as a rule, it is considered a justification for legality , resulting in no punishment or liability for damages.
The state of necessity (or compulsion) arises when, faced with a grave and imminent danger , a lesser value must be damaged in order to protect a greater value; it is often considered a reason that removes culpability , and while criminal liability is waived, liability for compensation may still arise.

Therefore, the difference between "state of necessity and self-defense"is not merely a theoretical debate, but a vital distinction directly conviction, acquittal, and liability for damages . In each specific case, a meticulous assessment of all the circumstances and obtaining legal support from an expert criminal lawyer are essential to prevent loss of rights.
