The Principle of Fault and the Principle of No Punishment Without Fault

1. Introduction: The Place and Importance of the Principle of Fault in Criminal Law

In criminal law, the principle of culpability , and its classic expression, the principle of "no punishment without fault,"is an indispensable principle, both theoretically and practically, that determines the fundamental condition for punishing a person. Simply put, for someone to be punished, it is not enough for them to have committed an unlawful act; that act must be attributable to them as culpability. Where there is no culpability, criminal liability does not arise.

This principle is closely linked to both the principle of individual criminal responsibility and the presumption of innocence, guaranteed in the Constitution , and the provisions on responsibility contained in the Turkish Penal Code (TCK) . In particular, the provisions in the TCK intent, negligence, the mental element, the individuality of criminal responsibility , and impunity in cases where there is no fault , are legal reflections of the principle of "no punishment without fault."

In many criminal cases today, even when "the commission of the crime is proven," the defendant's culpabilitydetermines the existence, type, amount of punishment, and even a decision of acquittal. Therefore, the principle of culpability is not merely a theoretical concept; the investigation, prosecution, judgment, and execution phases, guiding the specific case.

This article will examine the principle of culpability and the principle of "no punishment without fault" in detail within the context of Turkish Criminal Law ; it will comprehensively evaluate relevant constitutional and legal regulations , theories of culpability , culpability in terms of intent and negligence , circumstances that eliminate or reduce culpability , the practical implications of the principle of culpability , and references to Supreme Court precedents .

2. What is the Concept of Fault? What Does the Principle of Fault Express?

2.1. The Meaning of the Concept of Fault in Criminal Law

In criminal law , culpability , in its simplest terms, is the moral reprehensibility of the perpetrator's unlawful act . In other words, if the legal system states that "this person could have acted differently legally while committing this act, and nevertheless chose to commit it," then that person is considered culpable

The concept of culpability the perpetrator's inner world, psychological state, level of knowledge and will, social situation, and subjective circumstances at the time of the event solely on the outcome of the act. Therefore, culpability is not limited to identifying an act that creates objective harm or danger; the psychological connection between the perpetrator and the act .

2.2. The Principle of Fault: No Punishment Without Fault

The principle of culpabilityexpresses the idea that underlies criminal responsibility:

No one can be punished without fault. It is essential that the unlawful act be connected to the perpetrator's intent or negligence, that is, their fault.

The practical consequence of this principle is as follows:

the perpetrator intent ,
negligence ,
Or if the act cannot be attributed to him in a spiritual sense (for example, due to reasons such as young age or mental illness),

No criminal liability will arise , and no punishment can be imposed on the person. The principle of culpability is, in a sense, a safeguard principle in criminal law that rejects the logic of "objective responsibility" (punishment solely based on the outcome)

3. The Constitutional Basis of the Principle of Fault

3.1. Article 38 of the Constitution and the Principle of Personal Responsibility in Crimes and Punishments

Article 38 of the Constitution of the Republic of Turkey contains many fundamental principles of criminal law. "criminal responsibility is personal" also forms the basis of the principle of culpability.

The principle of individual criminal responsibility means that a person cannot be punished for the actions of another . However, this does not only mean that one cannot be held responsible for the actions of another; it also implies that a person must be at fault in order to be punished for their own actions. Because if there is no fault, then there is no moral link between the act and the person that would justify criminal responsibility .

3.2. Connection with the Presumption of Innocence

The presumption of innocence enshrined in the Constitution stipulates that every accused person shall be presumed innocent until proven guilty. This presumption requires proof not only of the objective existence of the act but also of its commission negligently

Therefore, the presumption of innocence indirectly reveals that in criminal proceedings, the burden of proof for the existence of fault rests with the prosecution . In cases where fault cannot be proven, an acquittal should be granted as a natural consequence of the principle of fault, in accordance with the principle that "the defendant benefits from the doubt."

4. The Reflection of the Principle of Culpability in the Turkish Penal Code

4.1. Mental Element (Intent and Negligence) and Fault

In the Turkish Penal Code, the mental element holds a significant place among the elements of a crime. The mental element refers to the perpetrator's knowledge and will regarding the act. From the perspective of the Turkish Penal Code's systematics, there are two basic types of culpability:

Intent (Turkish Penal Code Article 21)
Negligence (Turkish Penal Code Article 22)

In both cases, the law stipulates that the perpetrator must have acted negligently . The principle of culpability is clearly evident here: the law accepts that criminal liability does not arise without intent and negligence, which are types of culpability.

4.2. The Principle of "No Punishment Without Fault" in the Turkish Penal Code

The fundamental approach of the Turkish Penal Code is shaped in accordance with the principle of "no punishment without fault." A moral link between the act and the perpetrator that justifies criminal responsibility is sought; the legislator refuses to punish in cases where intent or negligence is absent.

In this context, the following points are particularly important:

Even in cases of crimes aggravated by the resulting consequences , the perpetrator must be at least negligently at fault to be held liable for the serious consequences .
In crimes committed through negligent conduct, for the negligent act to be punishable, it must be shown that the perpetrator a legal or contractual obligation and that their conduct in breach of this obligation was culpable.
in crimes involving endangerment , if the perpetrator's dangerous act lacks intent or negligence, the "created danger" alone is not sufficient grounds for punishment.

4.3. The Personal Nature of Criminal Responsibility (Turkish Penal Code Article 20) and Fault

Article 20 of the Turkish Penal Code regulates the principle of individual criminal responsibility. This article states:

No one can be held responsible for the actions of another,
Legal entities are not criminally liable, but security measures may be imposed

This has been clearly stated. Here, too, a connection is made with the principle of fault; because criminal responsibility can only be based on the individual's own fault . Legal entities, on the other hand, cannot be considered culpable in the classical sense, and therefore, only security measures , not criminal penalties, can be applied against them.

5. Types of Fault: Intent, Possible Intent, Conscious Negligence, and Negligence

5.1. Intent: Committing the Crime Knowingly and Willfully

Intent is when the perpetrator knowingly and willingly commits an act that fulfills the elements defined in the law . According to the classical theory of culpability, intent is the most intense form of culpability. From the perspective of the principle of culpability, the existence of intent indicates that the act is most severely reprehensible on the part of the perpetrator.

If intent exists:

The act, which is typical of the crime, was committed consciously and voluntarily
The perpetrator foresaw that an unlawful outcome would occur and desired that outcome
Although he was legally permitted to act differently, he knowingly and willingly chose an unlawful course of action.

Therefore, because the degree of culpability is higher in intentionally committed crimes, harsher penalties prescribed.

5.2. Potential Intent: Fault through Acceptance of the Outcome

Intentional intent (dolus eventualis)refers to the act where the perpetrator, while foreseeing the possibility of the outcome defined in the legal definition of the crime, acts with a "let it happen" mentality. The perpetrator does not directly desire the outcome, but accepts the possibility of it occurring.

Even in cases of indirect intent, culpability exists because the perpetrator consciously chooses to continue with their act instead of preventing the foreseen outcome. According to the principle of culpability, although the degree of culpability in indirect intent is considered less severe than in direct intent, criminal responsibility remains; however, the legislator a reduction in .

5.3. Conscious Negligence: Acting with the Hope of Preventing the Foreseen Outcome

Conscious negligencesituation where the perpetrator, despite foreseeing the outcome, relying on the belief that the outcome will not occur . Here, the perpetrator knows that the outcome defined in the legal definition of the crime may occur, but nevertheless continues to act, relying on their own skill, luck, or other reasons.

In cases of conscious negligence fault exists, but unlike intent, the perpetrator does not desire the outcome; they simply carelessly or with excessive confidence . Therefore, the law prescribes a heavier penalty for conscious negligence than for negligent crimes, taking into account the increased degree of fault.

5.4. Negligence: Failure to Exert Due Care and Diligence

Negligencewhen a perpetrator's foresee the outcome defined in the law, despite it being foreseeable . In negligent crimes, the degree of culpability is less severe; the perpetrator neither intended nor foresaw the outcome, but failed to foresee an outcome that they should have foreseen.

In negligent offenses, the principle of culpability works as follows:

The outcome could have been avoided if the care and attention expected of a reasonable person had been exercised
The perpetrator did not show this care and attention,
Therefore, the result can be attributed to him as a fault.

For example, negligent liability frequently arises in traffic accidents, workplace safety violations, and professional errors by healthcare personnel.

6. Reasons that Eliminate or Reduce Defectiveness

6.1. Young Age, Mental Illness, and Capacity for Culpability

One of the key elements of classical culpability theory the concept of culpability. For a person to be considered culpable, possess the mental and psychological capacity to understand the legal meaning and consequences of their actions and to direct their behavior accordingly .

In the Turkish Penal Code, situations that eliminate or reduce the capacity for culpability are regulated under the following headings:

Minority: Children under a certain age have no criminal liability or only limited criminal liability.
Mental illness: If a person's ability to perceive reality and control their behavior is impaired due to mental illness at the time the act is committed, they lack culpability.
Temporary causes: Conditions such as temporary loss of consciousness or severe intoxication can, under certain circumstances, affect the capacity for culpability.

In these cases, according to the principle of culpability, the person is either not punished at all or the punishment is reduced according to the degree of culpability. Thus, no punishment without fault is protected in this specific case.

6.2. Grounds for Lawfulness and Fault

In some cases, even if an act appears typical and harmful, grounds for justification . For example:

Self-defense,
State of necessity,
Exercise of the right,
Enforcement of the law.

In these cases, even if the act is typical, the element of unlawfulness disappears. From the perspective of the principle of fault, if grounds for lawfulness exist, the act ceases to be blameworthy; that is, fault cannot be attributed. Therefore, no punishment can be imposed because the element of blameworthiness required by the principle of fault has disappeared.

6.3. Surprise, Compelling Reasons, and Reduction of Fault

In some cases, the perpetrator may commit the act under severe threat , compelling circumstances , extreme distress, or fear . While complete blamelessness is not possible in such situations, the degree of culpability is generally considered reduced

Criminal law, taking these psychological states into account, the possibility of reducing the sentence , thus ensuring that the perpetrator is held responsible for the punishment they truly deserve, in accordance with the principle of culpability.

7. The Practical Importance of the Principle of Fault

7.1. Assessment of Fault During the Investigation Phase

In a criminal investigation, the public prosecutor is obligated to investigate not only whether "the act was committed," but also whether the suspect committed the act negligently . Specifically:

The suspect's role in the incident,
Whether the act was committed intentionally or negligently,
Whether there is any legal justification, any circumstance that eliminates or reduces culpability,
The suspect's age, mental health, and level of awareness at the time of the incident,

This should be evaluated within the framework of the principle of fault. In cases where fault cannot be demonstrated or there is serious doubt, a decision of no grounds for prosecution may be considered.

7.2. The Determinant Role of Fault in the Prosecution and Judgment Phases

When the court delivers its verdict:

The typicality of the crime,
Its illegality,
The flaw,

The court must evaluate each case separately. In particular , due to the principle of "no punishment without fault," the court cannot issue a conviction without establishing the defendant's intent or negligence regarding the act

Degree of defect:

conviction or acquittal decision,
In determining the amount of the penalty,
postponement of the announcement of the verdict, deferment, and conversion to a judicial fine ,

Because it has a direct impact, it is one of the key criteria determining the outcome of a trial.

7.3. The Principle of the Benefit of Doubt and Fault

If clear and convincing evidence regarding the existence or severity of the fault cannot be obtained, the principle of "the benefit of the doubt goes to the accused," a fundamental principle of criminal justice, comes into play.

For example:

If it is unclear whether the defendant acted intentionally or negligently in the incident,
If it is not entirely clear whether the duty of care and diligence that would give rise to negligent liability has been violated,
If there are seriously conflicting reports regarding whether or not the person has the capacity to be at fault,

This doubt should be interpreted in favor of the defendant, and taking into account the principle of culpability, an acquittal or a lighter sentence should be granted.

8. The Principle of Fault and the Prohibition of Objective Liability

8.1. Why is Objective Responsibility Not Accepted in Criminal Law?

Objective responsibilitymeans that a perpetrator should be punished simply because a consequence has occurred, regardless of whether or not they were at fault. This approach is incompatible with the fundamental principles of modern criminal law, particularly the principle of culpability and human dignity .

The Turkish criminal justice system rejects imposing penalties based on the outcome without seeking fault. This is because punishment is the most severe form of state intervention, and such intervention only be applied in response to culpable behavior ; this is a requirement of a state governed by the rule of law.

8.2. Legal Entities, Security Measures and Fault

Legal entities are not held criminally liable, but security measures may be applied against them. This is consistent with the principle of culpability; because legal entities cannot be considered in the same way as natural persons who possess free will and fault in the classical sense

However, managers and representativesbear criminal responsibility in proportion to their degree of fault. Thus, the penal system both protects the principle of culpability and can effectively respond to crimes committed within the activities of a legal entity through security measures.

9. Concrete Implications of the Fault Principle with Examples from Everyday Life

9.1. Fault and Criminal Liability in Traffic Accidents

Traffic accidents are one of the areas where the principle of fault is most frequently applied. For example:

Drivers who speed, run red lights, or drive under the influence of alcohol are generally liable for deaths and injuries resulting from such actions, either through negligence or willful negligence .
Conversely, if a driver who complies with all traffic rules, adheres to the speed limit, and whose vehicle is technically suitable, an extraordinary traffic violation by another driver , in most cases they will not be found criminally at fault and will not incur criminal liability.

In these examples, even if the same outcome (e.g., death) occurs, the drivers' criminal liability differs according to the principle of fault.

9.2. Employer and Employee Fault in Workplace Accidents

In workplace accidents, the fault of both the employer and the employee is assessed separately. Employer:

If occupational health and safety measures have not been taken,
If it has not provided adequate training and equipment,
If, despite dangerous working conditions, the necessary precautions have not been taken,

The employer may be held liable for negligence resulting in injury or death. Conversely, if the worker has received the necessary training, and occupational safety measures have been taken, but the worker through grossly negligent conduct , the employer's degree of fault will be reduced, and in some cases, no criminal liability may arise at all.

9.3. Responsibility of Healthcare Personnel and Medical Negligence

The principle of fault is also critically important for doctors and healthcare personnel. During treatment:

Medical standards were followed,
The necessary examinations have been carried out
The patient's condition has been assessed,

Even if an undesirable outcome occurs, that not every outcome automatically gives rise to criminal liability . According to the principle of fault, if the physician's conduct is not negligent, the act is not legally reprehensible, and therefore no criminal liability will arise.

10. The Place of the Principle of Fault in the Case Law of the Supreme Court of Turkey (General Assessment)

The Court of Cassation, its criminal chambers, and the General Assembly of Criminal Chambers consistently conduct detailed assessments of the existence and degree of the defendant's culpability in almost every type of crime , applying the principle of culpability in their jurisprudence. The following points are particularly emphasized in these decisions:

No conviction can be handed down unless intent or negligence is proven by evidence based on the specific circumstances of the case,
Especially in negligent offenses, it is necessary to thoroughly investigate whether the defendant had a duty of care and diligence that could be attributed to them,
In doubtful and uncertain situations, the existence of fault cannot be presumed against the defendant,
It is essential to obtain reliable and consistent expert reports regarding defendants whose capacity for culpability is questionable .

This approach demonstrates that the principle of "no punishment without fault" a fundamental criterion .

11. The Relationship of the Principle of Culpability to Other Principles of Criminal Law

11.1. Relationship with the Principle of Legality

In criminal law the principle of legalitymeans that the law must determine which acts constitute crimes and which sanctions are penalties. The principle of culpability, on the other hand, states that only those who are culpable, and not everyone who commits an act defined as a crime by law, can be punished .

When these two principles are considered together:

The principle of legality "which act is punishable" .
The principle of culpability answers the question of "who can be punished and to what extent."

Therefore, in the modern criminal justice system, "no crime and no punishment without law"and " no punishment without fault" are complementary parts of the same whole.

11.2. Relationship with the Principle of Proportionality

The principle of proportionalityrequires that the punishment be commensurate with the severity of the act committed and the degree of culpability of the perpetrator. The principle of culpability, by directly linking the punishment to the perpetrator's fault, is naturally consistent with the principle of proportionality.

Briefly:

More serious offense (such as intentional homicide) → Harsher penalty
Lesser fault (such as negligence, unconscious negligence) → Lighter penalty.

This systematic approach supports both the satisfaction of the sense of justice and the healthy achievement of the preventive and rehabilitative aims of criminal law

12. The Principle of Fault and a Human Rights Perspective

Criminal law is an area that allows the state to use the most severe means of intervention against the individual. Therefore, it must be compatible with human rights law . The principle of culpability:

Preventing arbitrary punishment,
Limiting the state's power to punish ,
It is a principle that serves as a safeguard in favor of the individual .

Although the term "principle of fault" is not explicitly used in international human rights texts, the understanding that criminal responsibility should be based on a person's personal actions and fault is a natural consequence of respect for human dignity . In this sense, the principle of fault is not merely a technical concept belonging to national criminal law dogma, but also a reflection of a rights-based approach .

13. Conclusion: The Importance of the Principle of Fault and the Principle of "No Punishment Without Fault" for Society and the Legal Order

The principle of fault and the principle of "no punishment without fault"criminal law from a mere "law of consequences" that takes into account the individual's will, consciousness, psychological state, and social conditions . Thanks to this:

A person is punished only to the extent of their fault ,
Persons who lack the capacity for culpability or who are not at fault are not liable for criminal offenses.
The punishment justice, proportionality, and human dignity .

When the provisions in the Turkish Penal Code regarding intent, negligence, capacity for culpability, grounds for legality, and mitigating circumstances are considered together, they clearly demonstrate that the system places the principle of culpability at its center . In practice, both during the investigation and prosecution phases, the existence, type, and degree of the defendant's culpability must be meticulously investigated in each specific case; and the evidence must be evaluated within this framework.

In conclusion, "no punishment without fault " is not merely an abstract principle found in legal texts, but a vital safeguard at every stage of criminal proceedings, directly affecting individual liberty, and rule of law and human rights . Therefore, awareness of the meaning and consequences of this principle by both practitioners (judges, prosecutors, lawyers) and citizens for a fair, balanced, and predictable criminal justice system .
