It is possible to claim compensation for unlawful administrative detention; however, before which court and by which procedure the claim is to be brought is an important practical problem, particularly for losses arising from the detention itself. In its K.N. pilot judgment, the Constitutional Court found that this uncertainty undermines the right to effective compensation. A one-sentence answer that sends every file directly to the administrative court or to the criminal judgeship of peace (sulh ceza hâkimliği) is therefore not sufficient.
The first step is to identify the cause of the loss: unlawful deprivation of liberty, poor conditions at the centre, a failure in health care or some other act may require different legal assessments. Release, a finding of unlawfulness, redress of the violation and payment of money are separate outcomes.
What is the legal basis of the right to compensation?
The right to liberty and security of person
Article 19 of the Constitution regulates the conditions and safeguards for deprivation of liberty. The ninth paragraph provides that the losses of those treated contrary to these principles are to be compensated by the State in accordance with the general principles of compensation law. That administrative detention is not a penalty does not remove the requirement that deprivation of liberty be lawful.
The claim may rest on a detention decision made without the statutory conditions being met, on the maximum period being exceeded, on an extension without sufficient grounds, or on the failure to provide the necessary procedural safeguards. It must be explained which period and which decision each allegation concerns. It may also be argued that a measure lawful on the first day became unlawful in a later period.
Release is not the same as a finding of unlawfulness
Detention may also end because circumstances later change. Therefore, it cannot be concluded from the release document alone that the whole period of detention was unlawful. The reasoning of the criminal judgeship of peace’s decision may show whether it relied on the absence of the initial conditions, on the later disappearance of the need to continue, or on the expiry of the time limit.
Conversely, where the competent judgeship has expressly found unlawfulness, that finding cannot be disregarded in the compensation assessment. The finality of the decision, the period it covers and its operative result must be reflected accurately in the claim. For each head of loss claimed, the loss and the connection are explained separately.
Why is it necessary first to separate the cause of the loss?
| Issue raised | Basic assessment | Matter not to be confused with it |
|---|---|---|
| Unlawfulness of the detention itself | Constitution Article 19, the detention decision and the case law on jurisdiction | Adequacy of conditions at the centre |
| Poor accommodation or health conditions | Constitution Article 17 and effective redress; the conduct of the service | The mere existence of the detention decision |
| No redress despite detention found to be unlawful | Effective exercise of the right to compensation | The mere fact that a release decision was made |
| Inability to reach the merits because of uncertainty about the competent authority | The structural problem in the K.N. pilot judgment | The assumption that a result can be obtained directly without using any ordinary remedy |
The same person may have experienced several problems together. In that case, the events on which the losses rest are separated, common documents are linked, and care is taken not to seek redress twice for the same loss. The distinctions drawn in the petition help the court assess its jurisdiction and the merits of the dispute.
What does the K.N. pilot judgment say?
The date of the judgment and the dispute at issue
The K.N. judgment of the Plenary Assembly (Genel Kurul) of the Constitutional Court (AYM) is dated 20 November 2025; its application number is 2022/8989. The judgment was published in the Official Gazette (Resmî Gazete) dated 22 May 2026, No. 33261. The applicant applied first to the administrative judiciary and then to the criminal judgeship of peace for non-pecuniary damages after detention; the merits of the claims were not examined on grounds of jurisdiction.
The Court examined the picture produced in practice by its earlier case law accepting the full remedy action (tam yargı davası) as an effective remedy and by the decisions of the Court of Jurisdictional Disputes (Uyuşmazlık Mahkemesi) that treat the ordinary judiciary as competent. It noted that there are also different approaches within the ordinary judiciary as to which court is competent (§§ 38–43).
The structural problem identified
The Constitutional Court concluded that there is no clear mechanism, effective in practice, that can redress losses arising from unlawful administrative detention. It found a violation in respect of the ninth paragraph of Article 19 of the Constitution, read together with the second paragraph, and applied the pilot judgment procedure. The situation was notified to the Grand National Assembly (TBMM) for resolution of the problem (§§ 43–57).
This judgment does not remove the right to compensation. On the contrary, it shows that leaving unclear before which authority the right may be effectively asserted is itself a constitutional problem. At the same time, the judgment has not created a new single court of first instance for all files.
The scope of the four-month stay
The judgment stayed the examination of similar individual applications concerning the structural problem for four months from its publication. The period stated in the judgment expired on 22 September 2026. This period is not a four-month addition to the time limits of persons for bringing an action or an individual application.
As of 14 October 2026, no separately verified extension of the stay, and no special statutory route resolving the problem as a whole, has been identified in the sources accessed for this work. It should be noted that this is not a finding of the absolute absence of legislation. The current legislation and the Constitutional Court’s practice should be checked again when an application is made. The expiry of the period does not result in the automatic acceptance of every pending application or in the same amount of compensation.
How should the Court of Jurisdictional Disputes’ 2026 decision be read?
In its decision of 16 February 2026, E.2026/12, K.2026/85, the Court of Jurisdictional Disputes continued the approach that the ordinary judiciary is competent over compensation claimed for administrative detention. It also stated that the claim examined did not fall within Criminal Procedure Code No. 5271.
The decision explains that the power to determine which court within the ordinary judiciary is competent does not belong to the Court of Jurisdictional Disputes. The fact that, in the specific file, the civil court of first instance’s decision of lack of jurisdiction was set aside should not be presented as a ruling declaring the civil court of first instance indisputably and generally competent for all similar disputes.
In view of this case law, it is not appropriate to repeat only the earlier explanations of the full remedy action for a loss arising from the detention itself. Taking into account the decisions pointing to the ordinary judiciary and the general rules of jurisdiction, the civil court of first instance route may come into consideration; however, the reasoning for this choice, the nature of the claim and the current practice must be built separately in the file. The possibility of a jurisdictional objection and the constitutional application dimension are followed together.
The criminal judgeship of peace’s examination of an objection to a detention decision does not mean that the same judgeship will also decide on the merits of every compensation claim. Similarly, the fact that detention restricts liberty does not make the route under Article 141 of the Criminal Procedure Code (CMK), which concerns criminal investigations, apply of its own accord.
The importance of a decision finding unlawfulness
In the Constitutional Court’s Parhat Halmuradow judgment, the rejection of a claim for non-pecuniary damages despite the criminal judgeship of peace’s finding of unlawfulness was examined. The Court held that the compensation guarantee of the right to liberty and security of person had been violated (21 January 2025, Application No: 2021/38395, §§ 18–20).
A retrial was indicated as redress; the Constitutional Court did not itself order payment of the compensation claimed. This outcome shows that a finding of violation and an award of a specific amount directly are not the same thing. The fact that the decision concerned a case heard in the past before the administrative judiciary does not mean, disregarding K.N. and the later case law on jurisdiction, that every new case will today be brought in the same place.
How are pecuniary and non-pecuniary loss made concrete?
Pecuniary loss and causation
Pecuniary compensation requires the alleged loss to be explained with documents and calculation. Treatment expenses, a specific loss of income or other economic losses connected with the event may be claimed; it must be shown that they were incurred and are connected with the unlawful act. Simply multiplying a daily figure by the days of detention does not constitute sufficient proof in every file.
For loss of income, the nature of the employment relationship and of the lawful opportunity to work, income documents and the period from which the loss arises are important. Periods in which there is no dispute about lawfulness must be separated from the periods in which a violation is alleged. If payment has previously been made for the same loss, this must be explained.
Non-pecuniary loss and personal impact
The length of the deprivation of liberty, separation from the family, the person’s health and vulnerability, the effect of uncertainty and shortcomings in procedural safeguards may matter in the assessment of non-pecuniary loss. Health and family documents present a more concrete picture than an abstract account of distress.
The 10,000 Turkish lira (TL) awarded in the K.N. judgment and the TL 115,000 in the İbrahim Muhammed Ali judgment are redress for different violations and different files. A daily compensation tariff or a minimum guarantee applicable to everyone cannot be derived from them. The reasoning for the amount claimed and the redress the court will determine in its discretion are separate matters.
How are the application time limits protected?
A claim of administrative action arising from conditions at the centre
Where a full remedy action for administrative action is concerned, Article 13 of the Administrative Procedure Law No. 2577 (İYUK) provides for a prior application to the relevant administration within one year of learning of the act and in any case within five years of the date of the act. Upon an express refusal, or upon thirty days without a reply, the time limit for bringing an action comes into play; the general time limit for bringing an action in administrative courts is sixty days, unless there is a special provision.
These rules are not the single calendar to which every administrative detention compensation claim is automatically subject. If the loss rests on an administrative act, İYUK Article 12 applies; if jurisdiction lies in another branch of the judiciary, the relevant procedural rules are assessed separately. In situations such as a continuing act, later discovery of the loss or a decision of lack of jurisdiction, the starting and protective provisions require special examination. The one-year period must not be used to put all applications on hold.
The general thirty-day rule in an individual application
Under Article 47 of Law No. 6216, the general rule is thirty days from exhaustion of the remedies and, where no remedy is provided, from learning of the violation. The records of learning of the decision and of its notification should be kept. A new objection to detention based on changed circumstances does not of itself restart the individual application period for a past final decision.
In the K.N. judgment, the Constitutional Court considered that, under the specific conditions, the applicant could not be expected to exhaust additional jurisdictional applications that offered no practically meaningful chance of success (§ 42). This finding is not a general formula allowing all ordinary remedies to be treated as unnecessary in every new file. The right relied on, the earlier decisions, the nature of the claim and the route actually accessible must be explained.
Which documents are needed when preparing the file?
- The initial detention, continuation and extension decisions and the notification documents.
- The dates of actual apprehension, admission to the centre, transfer and release.
- The applications to the criminal judgeship of peace and all the reasoned decisions.
- The relevant decisions and developments in the deportation file.
- Health, family, income and expense documents; receipts for earlier complaints.
- The administrative and judicial applications concerning the compensation claim, the decisions on jurisdiction and the records of learning.
These documents are placed in a chronology. For each head of loss, the event, the allegation of unlawfulness, the evidence and the redress sought are compared. If a document is not yet in hand, its source is stated and a request to obtain it is made. Uncertainty about jurisdiction is not a reason to postpone gathering evidence or tracking time limits.
Conclusion
Seeking effective redress after unlawful administrative detention is a constitutional right. The uncertainty about jurisdiction in practice was clearly shown by the K.N. pilot judgment. A sound application separates the loss arising from the detention itself from the loss arising from conditions at the centre, evaluates the reasoning of the relevant decisions, and tracks the time limits separately. Depending on the characteristics of the file, redress may take the form of a retrial, other measures aimed at redressing the violation, or compensation; the outcome cannot be guaranteed in advance.

Frequently Asked Questions
Can everyone who leaves the centre obtain compensation?
No. The reason for release, the unlawfulness, the loss and the conditions of application are assessed. The exit record alone does not show that the whole detention was unlawful.
Must a compensation action necessarily be brought in the administrative court?
No. For a loss arising from the detention itself, the Court of Jurisdictional Disputes’ case law on the ordinary judiciary and the K.N. pilot judgment must be taken into account. Losses from administrative action arising from conditions at the centre are assessed separately.
Does the criminal judgeship of peace also determine compensation when it lifts the detention?
The duty to examine an objection to detention does not mean authority to examine every compensation claim. The reasoning of the decision and the separate route to redress must be assessed.
Does compensation for unjustified pretrial detention under the CMK apply directly?
Administrative detention does not become a criminal investigation measure merely because it restricts liberty. The Court of Jurisdictional Disputes’ decision No. 2026/85 states that the claim examined did not fall within the CMK.
Are the four months in the K.N. judgment added to the application period?
No. The stay concerns the Constitutional Court’s examination of certain applications. It does not extend the time limits for bringing an action or for an individual application; the period stated in the judgment expired on 22 September 2026.
Does the Constitutional Court necessarily award money when it finds a violation?
No. A retrial or another measure may be considered sufficient to redress the violation. In the Parhat Halmuradow judgment, the retrial route was applied.
