Treaty Bodies and Special Procedures
The United Nations human rights system operates through two complementary pillars: treaty bodies, established under international human rights conventions, and special procedures, comprising independent Special Rapporteurs, Independent Experts, and Working Groups. Together, these mechanisms monitor states’ compliance with their human rights obligations, examine individual complaints where applicable, respond to urgent situations, and seek explanations from governments regarding alleged violations. This section provides a concise overview of how the UN treaty bodies and special procedures function, the circumstances in which these mechanisms can be engaged, and the practical avenues available for individuals and organisations seeking to raise human rights concerns, including those relating to Türkiye.
The United Nations is composed of various organs and human rights mechanisms designed to promote and protect fundamental rights worldwide. Within the UN human rights framework, two principal categories of mechanisms play a central role. The first consists of treaty bodies, whose mandates are established directly by international human rights treaties. The second comprises the special procedures created by the United Nations Human Rights Council through specific mandates. This institutional structure enables the UN to address a broad range of human rights issues through specialised and complementary mechanisms.
The UN human rights system operates through two main pillars:
Treaty Bodies – Committees established under international human rights treaties to monitor how States Parties implement their treaty obligations. Their mandates, powers, and procedures derive directly from the respective human rights conventions that states have ratified.
Special Procedures – Independent human rights experts, including Special Rapporteurs, Independent Experts, and Working Groups, appointed by the United Nations Human Rights Council to examine, monitor, advise on, and publicly report on thematic human rights issues or country-specific situations.
These mechanisms help bring human rights violations to light through state reporting procedures, individual complaint mechanisms, country visits, communications with governments, and urgent interventions. They request information and explanations from states, issue findings and recommendations, and monitor the implementation of their recommendations through follow-up procedures.
A) Treaty Bodies: What Do They Do and How Do They Work?
Key Functions
State Reporting and Constructive Dialogue
Treaty bodies regularly examine periodic reports submitted by States Parties on the implementation of their obligations under the relevant human rights treaties. Following a constructive dialogue with government representatives, the committees adopt Concluding Observations, identifying areas of concern, recognising positive developments, and making recommendations for improving compliance.
Individual Communications
Several UN human rights treaties allow individuals to submit complaints directly to a treaty body, provided that the state concerned has recognised the committee’s competence through an optional protocol or a specific declaration.
Individual communications are subject to a number of admissibility requirements, including:
exhaustion of available domestic remedies;
the complaint must not be anonymous;
the same matter must not already be under examination by another international procedure of investigation or settlement; and
the application must be sufficiently substantiated.
Where there is a risk of irreparable harm, the committee may request interim measures to preserve the rights of the applicant while the case is pending. Following its examination, the committee adopts its Views, which include its legal findings and, where appropriate, recommendations for remedies. The implementation of these Views is subsequently monitored through dedicated follow-up procedures.
Procedure and Timeframe
Unlike many international courts, most UN treaty bodies do not impose a strict statutory time limit for submitting an individual communication. For example, the United Nations Human Rights Committee does not prescribe a formal limitation period. However, an application may be declared inadmissible if it is submitted after an unreasonable delay amounting to an abuse of the right of submission under Rule 96(c) of its Rules of Procedure.
Upon registering a communication, a committee may request interim measures where necessary and normally invites the respondent state to submit written observations, often within six months. Communications are generally considered in closed session, after which the committee’s Views are published.
Note: Although the Views adopted by UN treaty bodies are not legally binding in the same manner as judgments of an international court, they constitute authoritative interpretations of the relevant human rights treaties. They carry significant legal and persuasive weight in international law and establish expectations that states provide effective remedies and act in good faith to implement the committees’ findings.
1. Which Treaty Bodies Exist?
There are currently ten UN treaty bodies, each established under a specific international human rights treaty to monitor States Parties’ compliance with their treaty obligations:
United Nations Human Rights Committee (HRC) – Monitors the implementation of the International Covenant on Civil and Political Rights.
Committee on Economic, Social and Cultural Rights – Monitors the implementation of the International Covenant on Economic, Social and Cultural Rights.
Committee on the Elimination of Racial Discrimination – Oversees compliance with the International Convention on the Elimination of All Forms of Racial Discrimination.
Committee on the Elimination of Discrimination against Women – Monitors the implementation of the Convention on the Elimination of All Forms of Discrimination against Women.
Committee against Torture – Supervises implementation of the Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment.
Committee on the Rights of the Child – Monitors compliance with the Convention on the Rights of the Child.
Committee on the Protection of the Rights of All Migrant Workers and Members of Their Families – Oversees implementation of the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families.
Committee on the Rights of Persons with Disabilities – Monitors the implementation of the Convention on the Rights of Persons with Disabilities.
Committee on Enforced Disappearances – Monitors compliance with the International Convention for the Protection of All Persons from Enforced Disappearance.
Subcommittee on Prevention of Torture – Established under the Optional Protocol to the Convention against Torture to prevent torture through visits to places of detention and cooperation with national preventive mechanisms.
Note: The Committee on Enforced Disappearances (CED) is the treaty body established under the Convention on Enforced Disappearances. The Working Group on Enforced or Involuntary Disappearances (WGEID), by contrast, is not a treaty body; it is a Special Procedure of the United Nations Human Rights Council. This distinction is important because the two mechanisms have different legal mandates and procedures.
2-The Main Functions of Treaty Bodies
UN treaty bodies perform several key functions to monitor and promote states’ compliance with international human rights treaties.
Reviewing State Reports
States Parties are required to submit periodic reports explaining the measures they have taken to implement their obligations under the relevant treaty. Treaty bodies examine these reports through a constructive dialogue with government representatives and also consider shadow reports submitted by civil society organisations, national human rights institutions, and other stakeholders. Following this review, they adopt Concluding Observations, which identify areas of concern, recognise positive developments, and provide recommendations for improving compliance.
Examining Individual Communications
Several treaty bodies are empowered to receive individual complaints alleging violations of treaty rights, provided that the state concerned has accepted the relevant complaints procedure. After considering the parties’ submissions, the committee adopts its Views, setting out its legal assessment of the alleged violations and recommending appropriate remedies where necessary. Although these Views are not legally binding in the same way as judgments of international courts, they are regarded as authoritative interpretations of the relevant treaties and carry significant legal, political, and persuasive weight.
Issuing General Comments
Treaty bodies regularly adopt General Comments (or General Recommendations, depending on the committee) to clarify the scope and meaning of treaty provisions. These interpretative documents explain states’ obligations under international human rights law and provide authoritative guidance for governments, domestic courts, practitioners, and international organisations.
Conducting Inquiries and Country Visits
Certain treaty bodies are authorised to initiate confidential inquiries where they receive reliable information indicating grave or systematic human rights violations. Some mechanisms may also conduct country visits, subject to the applicable treaty provisions and the consent of the state concerned. In particular, the Committee against Torture may initiate inquiries under Article 20 of the Convention against Torture, while the Subcommittee on Prevention of Torture conducts preventive visits to places of detention under the Optional Protocol to the Convention against Torture, working in cooperation with national preventive mechanisms to help prevent torture and other forms of ill-treatment.
3. How Do They Operate?
The principal characteristics and working methods of the UN treaty bodies are as follows:
Independence: Committee members are independent experts who serve in their personal capacity rather than as representatives of their governments. They are elected by the States Parties to the relevant treaty for fixed terms of office.
Sessions: Treaty bodies generally meet several times each year. Their sessions are primarily held in Geneva or New York.
Transparency and Participation: The work of the treaty bodies is largely transparent. Civil society organisations, academics, national human rights institutions, and other stakeholders may contribute to the process through mechanisms such as shadow reports and oral briefings.
Follow-up Procedures: Treaty bodies monitor the extent to which States Parties implement their recommendations. Where implementation is insufficient, they may request additional information, follow-up reports, or further clarification from the state concerned.
Türkiye has currently accepted the individual communications procedure for four of the ten UN treaty bodies:
United Nations Human Rights Committee (HRC) – under the International Covenant on Civil and Political Rights
Committee against Torture
Committee on the Elimination of Discrimination against Women
Committee on the Rights of Persons with Disabilities
For the remaining treaty bodies, Türkiye is either not a State Party to the relevant treaty or has not accepted the optional protocol or declaration establishing the individual communications procedure.
B) Special Procedures: Special Rapporteurs & Working Groups
B) Special Procedures: Special Rapporteurs and Working Groups
The Special Procedures are independent human rights experts and five-member Working Groups appointed by the United Nations Human Rights Council. They monitor either thematic human rights issues—such as freedom of expression, torture, the independence of judges and lawyers, or the situation of human rights defenders—or country-specific human rights situations.
How Do They Operate?
Communications
Special Procedures engage with governments primarily through formal communications, including:
Urgent Appeals – Sent in cases involving ongoing violations or situations where there is an imminent risk of irreparable harm requiring immediate intervention.
Allegation Letters – Issued in relation to alleged human rights violations that have already occurred, requesting information, clarification, and, where appropriate, remedial action.
These communications are transmitted to the government concerned. Unless confidentiality is exceptionally maintained, they are published in the UN communications database after a 60-day confidentiality period. Unlike most treaty body complaint procedures, there is generally no requirement to exhaust domestic remedies before submitting information to the Special Procedures.
Country Visits and Thematic Reports
Special Procedures also conduct country visits, subject to the consent of the state concerned, and prepare thematic reports on issues within their mandates. Through these activities, they assess human rights situations, document their findings, make concrete recommendations to states, and monitor the implementation of those recommendations.
Two Key Working Groups
Working Group on Arbitrary Detention
The Working Group on Arbitrary Detention is the only non-treaty mechanism with a dedicated quasi-judicial individual complaints procedure. It receives individual petitions, transmits allegations to the government concerned, typically allows 60 days for a response, and adopts Opinions assessing whether a deprivation of liberty is arbitrary under international law. In urgent situations, it may also activate its Urgent Appeal procedure.
Working Group on Enforced or Involuntary Disappearances
The Working Group on Enforced or Involuntary Disappearances operates both an urgent procedure, generally available during the first three months following a disappearance, and a standard procedure thereafter. Exhaustion of domestic remedies is not required. Cases may be submitted by family members or, with their consent, by non-governmental organisations. Confidentiality is a fundamental feature of the procedure.
Example of Engagement with Türkiye
During its 137th session in 2025, the Working Group on Enforced or Involuntary Disappearances reported that it had examined both urgent and standard cases concerning numerous countries, including Türkiye. In such cases, the Working Group engages in correspondence with the government concerned in an effort to clarify the fate or whereabouts of disappeared persons.
C) Notes on Türkiye
Human Rights Committee (HRC) – Scope of the ICCPR
Türkiye is a party to the First Optional Protocol to the International Covenant on Civil and Political Rights (ICCPR) and has recognised the right to submit individual communications to the Human Rights Committee (HRC).
Important Reservation: When recognising the Committee’s competence, Türkiye entered a reservation requiring that “the same matter has not been and is not being examined under another procedure of international investigation or settlement.” Therefore, an application cannot be submitted to the HRC in relation to a case that is pending before, or has already been decided by, the ECtHR.
Committee against Torture (CAT) – Article 22
Türkiye accepted the individual communications procedure under Article 22 of the Convention against Torture (CAT) through its 1988 declaration.
Use in Practice: This is one of the most effective avenues for complaints concerning torture, ill-treatment, and especially alleged violations of the principle of non-refoulement. In individual cases, the Committee requests a response from the state within six months and, similar to the ECtHR, may request interim measures to suspend deportation or removal procedures.
Committee on the Elimination of Discrimination against Women (CEDAW) – Optional Protocol
Türkiye is a party to the Optional Protocol to CEDAW. This mechanism is particularly relevant in cases concerning domestic violence, gender-based discrimination, and equality in employment.
Temporal Jurisdiction: Individual communications may be submitted in relation to events that occurred after the Optional Protocol entered into force in January 2003.
Committee on the Rights of Persons with Disabilities (CRPD) – Optional Protocol
Türkiye ratified the Optional Protocol to the Convention on the Rights of Persons with Disabilities (CRPD) in 2015.
Focus: Accessibility, denial of reasonable accommodation, and discrimination. In addition to individual communications, the Optional Protocol also grants the Committee inquiry powers in cases involving systematic violations.
Committee on the Rights of the Child (CRC) – Third Optional Protocol
Türkiye is a party to the Third Optional Protocol to the Convention on the Rights of the Child on a communications procedure. In cases involving violations of children’s rights, individual communications may be submitted to this Committee after domestic remedies have been exhausted.
OPCAT and the National Preventive Mechanism (NPM)
Under the Optional Protocol to the Convention against Torture (OPCAT), the role of National Preventive Mechanism (NPM) in Türkiye is carried out by the Human Rights and Equality Institution of Türkiye (TİHEK).
Current Situation: In its visits to Türkiye, including its 2022 visit, and in its reports, the Subcommittee on Prevention of Torture (SPT) has drawn attention to safeguards in police custody and conditions in removal centres. International reports continue to emphasise the need to strengthen TİHEK’s independence and financial resources.
Summary and Strategy
Türkiye is party to five key mechanisms that allow individual communications under the HRC, CAT, CEDAW, CRPD, and CRC procedures. For legal practitioners, the strategic approach is to select the appropriate treaty body according to the nature of the alleged violation, for example CAT in cases involving deportation risk, or CRC in cases concerning children’s rights. These mechanisms may serve as effective alternative legal avenues, particularly at times when the ECtHR’s caseload is increasing.
