UN Human Rights System: An Overview
UN human rights mechanisms are among the most effective avenues through which individuals can seek justice at the international level when domestic remedies have become blocked or ineffective. Thanks to the core treaties to which Türkiye is a party, cases involving arbitrary detention, torture, enforced disappearance, and violations of the right to a fair trial are regularly examined by UN committees and working groups, which request explanations and corrective measures from states. On this page, we present a clear overview of which UN bodies may receive applications, how the procedures work, and effective application strategies in light of example decisions concerning Türkiye.
United Nations (UN) human rights mechanisms are international monitoring bodies that oversee states’ human rights obligations, assess violations, and examine applications submitted by individuals. These mechanisms provide individuals with an opportunity to seek justice at the international level, particularly where domestic remedies have become ineffective or where access to remedies has been blocked.
The foundations of the UN human rights system were laid in the aftermath of the Second World War. The Universal Declaration of Human Rights, adopted in 1948, was the first document to institutionalise the idea of protecting human rights at the international level. However, the Declaration was not legally binding. For this reason, binding international norms were later established through treaties such as the International Covenant on Civil and Political Rights (ICCPR) and the International Covenant on Economic, Social and Cultural Rights (ICESCR), both adopted in 1966. The treaty bodies established to monitor these conventions subsequently became effective mechanisms through which individuals may submit applications directly.
Türkiye has recognised the supervisory competence of these mechanisms through many of the core UN treaties to which it is a party. Particularly in the 2000s, within the framework of the European Union harmonisation process, Türkiye became a party to several of these treaties and recognised the right of individual application. These developments paved the way for individuals in Türkiye to seek justice before the UN at the international level when domestic remedies have become blocked or ineffective.
UN bodies do not merely examine applications. They also request explanations from governments, publish views and recommendations, and call for corrective measures to remedy violations. These mechanisms are divided into two main groups:
Treaty-Based Bodies:
Committees that monitor the obligations of states parties and examine individual applications, such as the Human Rights Committee for the ICCPR and the Committee Against Torture for CAT.
Special Procedures:
Special Rapporteurs and working groups appointed by the UN Human Rights Council, such as the Working Group on Arbitrary Detention (WGAD) and the Working Group on Enforced or Involuntary Disappearances (WGEID).
These mechanisms have examined numerous individual cases concerning Türkiye and, through findings of violations, have brought these cases to the attention of the international community. For example:
WGAD has issued decisions finding “arbitrary detention” in many cases involving individuals detained after 15 July 2016 on allegations of links to the Gülen movement. In a 2018 Opinion, it found the detention of an academic to be unlawful and called on Türkiye to release the individual immediately.
There are more than twenty similar Opinions. In its Opinions concerning arbitrary detention, including Opinion No. 66/2023 (para. 63), Opinion No. 3/2023 (para. 85), Opinion No. 66/2020 (para. 67), Opinion No. 67/2020 (para. 96), Opinion No. 84/2020 (para. 76), Meryem Tekin, Opinion No. 6/2024 (para. 67), and Akın Öztürk, Opinion No. 33/2024 (para. 87), the Working Group noted a significant increase over the past seven years in the number of cases concerning arbitrary detention in Türkiye brought before it. It expressed deep concern about the pattern followed by all these cases and recalled that, under certain circumstances, widespread or systematic imprisonment or other severe deprivation of liberty in violation of fundamental rules of international law may constitute crimes against humanity.
The Working Group and other international institutions have, particularly in their recent decisions, strongly condemned Türkiye’s detention and arrest practices targeting alleged members of the Gülen movement and characterised such practices, in certain circumstances, as potentially amounting to crimes against humanity.
WGEID has examined applications concerning Turkish citizens forcibly abducted from abroad and, in particular, brought to the agenda the situation of six people abducted from Kosovo in 2018, requesting explanations from Türkiye.
CAT has accepted applications submitted by individuals who alleged that they were subjected to torture and ill-treatment in custody and has found that Türkiye violated the prohibition of torture.
For many individuals, UN bodies function as a complementary legal avenue before reaching the European Court of Human Rights (ECtHR) process, or in situations where an ECtHR application cannot be submitted. Although UN decisions are not binding, they provide visibility within the international community, create diplomatic pressure on states, and may serve as a basis for domestic procedures such as retrial.
As a state party to the UN system, Türkiye is under an obligation to take these decisions and views into account and to act in accordance with the recommendations. However, the effective use of these procedures depends on victims’ access to accurate information, the proper preparation of their documents, and the timely submission of their applications.
