Unlawful detention refers to instances where an individual is deprived of their liberty without legal justification, in violation of the procedural guarantees laid out under Turkish law and international human rights standards. In Turkey, detention (gözaltı) and arrest (tutuklama) procedures are regulated by the Turkish Criminal Procedure Code (CMK) and the Turkish Constitution, particularly under Article 19, which secures the right to personal liberty and security. If a person has been detained without lawful cause, held longer than permissible time limits, or subjected to procedural violations such as not being promptly brought before a judge, this may constitute unlawful detention. In such cases, individuals have the right to seek compensation against the state under Articles 141–144 of the CMK, and in some cases, through the European Court of Human Rights (ECtHR) if local remedies are exhausted.
The Turkish Criminal Procedure Code provides a comprehensive framework for claiming damages arising from unjust judicial measures, including unlawful detention. Article 141 of the CMK allows individuals to sue the state for unlawful arrest or detention, even if there was no malicious intent by the authorities. These provisions cover cases where a person has been:
Importantly, the claim is not dependent on proving wrongful intent by the judge or prosecutor. It is a strict liability regime — meaning that the state may be liable even if the public authorities believed they were acting lawfully. This system reflects a commitment to the principle of rule of law and fair trial rights under Article 36 of the Turkish Constitution and Article 5 of the European Convention on Human Rights.
Any individual who has suffered damage due to unlawful detention in Turkey — whether Turkish citizen or foreign national — has standing to bring a compensation claim. This includes persons who:
Additionally, legal heirs of a person who has died following an unlawful detention may also bring a claim on behalf of the deceased’s estate. Importantly, the right to compensation does not require the individual to have been fully acquitted — even procedural violations may suffice for a successful claim.
To file a compensation claim for unlawful detention in Turkey, the claimant must initiate proceedings within three months from the date of final judgment (e.g., acquittal or decision of non-prosecution) and in any case within one year of the act that caused the damage. The claim is filed at the Heavy Criminal Court (Ağır Ceza Mahkemesi) that has jurisdiction over the matter. The procedure typically includes:
The process is exempt from court fees, meaning individuals can file these claims without incurring the usual litigation costs — a measure intended to enhance access to justice for victims of unlawful state actions.
Compensation awarded for unlawful detention typically falls under two categories: material (economic) and moral (non-economic) damages. Material damages may include:
Moral damages, which form the bulk of such claims, cover:
Turkish courts have awarded moral damages ranging from 20,000 TL to over 200,000 TL depending on the duration, conditions of detention, and severity of rights violations. The Constitutional Court and ECtHR may increase this amount in especially grave violations.
In addition to the regular compensation route under the CMK, individuals whose rights were violated during detention can file a “constitutional complaint” (bireysel başvuru) with the Turkish Constitutional Court under Article 148 of the Constitution. This must be filed within 30 days after the final decision of the judicial authority. The Constitutional Court may:
The court’s judgments are binding and carry high legal and reputational weight. Many landmark rulings on unlawful detention (including in political or high-profile cases) have come from this venue.

Yes. If all domestic remedies (including CMK proceedings and Constitutional Court applications) have been exhausted, victims may file a complaint before the European Court of Human Rights (ECtHR) under Article 5 of the European Convention on Human Rights. Turkey has been found in violation of this article numerous times, and the Court frequently awards just satisfaction to applicants — including moral damages, legal costs, and public recognition of state responsibility.

Several key Turkish and European judgments have shaped the practice of compensation for unlawful detention:
These rulings provide critical precedents that domestic courts also take into account when calculating damages.
The state may argue in its defense:
In such cases, the presence of procedural violations (e.g., not seeing a judge in time, no lawyer present) can significantly increase the likelihood of success. Therefore, documentation, timely legal action, and expert legal representation are crucial to success.
Compensation for unlawful detention is a fundamental legal remedy for protecting individual liberty and holding the state accountable for rights violations. In Turkey, both domestic mechanisms (through CMK and the Constitutional Court) and international forums (such as the ECtHR) provide clear and enforceable pathways for individuals to seek redress. By taking timely legal action and relying on the robust legal framework, victims of unlawful detention can reclaim their dignity, compensation, and public vindication.
