The Relationship Between the ECtHR Process and the UN Process
The ECtHR and the UN human rights system, the two mechanisms most frequently used by individuals seeking justice at the international level, have different procedures and structures. However, both play a critical role in making human rights violations in Türkiye visible and in seeking remedies for them.
Understanding how these two avenues intersect, in what ways they complement each other, and how they can be used together in application strategies is of vital importance for both lawyers and victims.
This page provides a clear and accessible overview of the relationship between the ECtHR process and UN mechanisms, their differences, and practical strategies for their use.
The European Court of Human Rights (ECtHR) and the United Nations (UN) human rights mechanisms are two separate but complementary systems that enable individuals to seek justice at the international level.
Both systems aim to monitor states’ human rights obligations and to provide effective remedies against violations.
However, there are important differences and points of intersection between these two processes in terms of their functioning, application requirements and legal effects.
1. Legal Basis and Structural Differences
| Feature | ECtHR | UN Mechanisms |
| Legal Basis | European Convention on Human Rights (ECHR) | UN Human Rights Treaties (ICCPR, CAT, etc.) |
| Institutional Structure | Judicial body (court) | Monitoring body committee, rapporteur, working group |
| Nature of the Decisions | Binding court judgment | Views and recommendations with legal authority |
| Supervision of Implementation | Committee of Ministers of the Council of Europe | OHCHR and the relevant committees |
| Geographical Scope | Member states of the Council of Europe | Global: all states parties to the relevant treaty. |
2. Application Requirements and the Issue of Double Examination
ECtHR Application:
Domestic remedies must have been exhausted.
Under the new rules, the application must be lodged within 4 months.
The application form must be complete and supported by evidence.
UN Committees (HRC, CAT, etc.):
Domestic remedies must have been exhausted.
If the same matter has already been examined by another international body, the application will be rejected.
For this reason, a case that has been examined by the ECtHR cannot be brought before the UN committees.
This limitation does not apply to UN special mechanisms such as the WGAD, WGEID and Special Rapporteurs. The same matter may be examined both by the ECtHR and by the WGAD.
3. Complementary Use Strategy
When used together with the right strategy, the ECtHR and UN mechanisms can serve complementary functions:
UN visibility before an ECtHR application: urgent intervention may be sought through the WGAD or Special Rapporteurs.
If the ECtHR process takes a long time: international public awareness may be raised through UN mechanisms.
If an ECtHR application cannot be lodged because the time limit has expired or domestic remedies have not been exhausted: UN special mechanisms may provide an alternative avenue.
UN follow-up after an ECtHR judgment: if the judgment is not implemented, UN mechanisms may be activated.
4. Türkiye Example: Parallel Processes
The human rights violations that occurred in Türkiye during the state of emergency period have been addressed by both the ECtHR and UN mechanisms.
Some cases brought before the ECtHR have been rejected by the UN Human Rights Committee on the grounds of “double examination.”
However, the WGAD has issued opinions concerning the same events and has called on Türkiye to release the individuals concerned and provide compensation.
This shows that UN special mechanisms can be used as supporting documentation in the ECtHR process.
5. Effect of Decisions and Supervision of Implementation
ECtHR judgments are binding, and Türkiye, as a member state of the Council of Europe, is under an obligation to implement them.
UN committee decisions are not binding; however, they constitute authoritative interpretations under international law.
UN decisions may be used, particularly in the ECtHR process, as evidence, legal arguments and instruments of international pressure.
6. Recommendations for Practitioners
Before lodging an application with the ECtHR, visibility may be created through UN special mechanisms.
If an application is to be submitted to UN committees, the case file should be prepared before initiating the ECtHR process.
For applications rejected by the ECtHR, UN mechanisms, particularly the WGAD and WGEID, may serve as an alternative avenue.
Decisions from both systems should be used together in national and international advocacy strategies.
Two Systems, One Purpose: Protecting Human Rights
Although the ECtHR and UN mechanisms have different structures and procedures, they are two powerful tools that complement each other in individuals’ pursuit of justice.
The conscious and strategic use of these systems increases both legal success and international visibility.
