United Nations special rapporteurs have raised serious concerns about Turkey’s use of counterterrorism laws to judicially harass and criminalize human rights defenders and lawyers, including what they described as the misuse of the terrorism financing law.
In a letter sent to the Turkish government on February 23, 2026, but published only recently, the rapporteurs said authorities were pursuing charges including membership in a terrorist organization and terrorism financing against rights defenders and lawyers, singling out the Human Rights Association (İHD) as a particular target.
The rapporteurs pointed to the cases İHD member Hatice Onaran, who was convicted in 2024 of “violating the law on financing terrorism” after sending small amounts of money to poor and sick prisoners. They also cited the cases of four other members —Osman Süzen, Suna Bilgin, Tuğba Kahraman and Mehmet Acettin — who were charged with membership in a terrorist organization. Süzen was subsequently acquitted at a January 2026 hearing.
A fifth İHD member, İsmail Boyraz, was investigated on accusations of participating in an unlawful assembly after taking part in a teachers’ union protest. The rapporteurs also cited the case of lawyer Sabri Güngen, who was allegedly assaulted by police while meeting with a client.
The rapporteurs expressed concern over what they described as Turkey’s “apparent misuse” of terrorism financing laws in Onaran’s case, noting that providing small sums of money to support the basic needs of ill and financially disadvantaged prisoners, in line with prison regulations and under prison administration supervision does not constitute terrorism financing under international law. Onaran, who is undergoing cancer treatment, was released in February 2025 after his sentence was suspended for six months on health grounds.
They also warned that physical assault and intimidation reportedly faced by lawyers Bilgin, Süzen and Güngen while carrying out their professional duties may have been acts of retaliation for their human rights work.
The rapporteurs said the alleged arbitrary detentions and due process violations constitute serious violations of the International Covenant on Civil and Political Rights (ICCPR), particularly regarding the rights to liberty, security, a fair trial and freedom of association and assembly.
The rapporteurs raised the same concern in a following statement on March 31, which warned that Turkey’s counterterrorism legislation is being used to criminalize legitimate rights advocacy and restrict fundamental freedoms.
The rapporteurs called on Turkish authorities to provide detailed information on the cases, including how the prosecutions comply with international human rights law and what measures are being taken to ensure that lawyers and human rights defenders can operate safely. They also urged a review of the counterterrorism law and called for interim measures to halt ongoing violations and ensure accountability for any reported ill-treatment.
The letter was signed by Mary Lawlor, the UN special rapporteur on human rights defenders; Gina Romero, the special rapporteur on freedom of peaceful assembly and of association; Tlaleng Mofokeng, the special rapporteur on physical and mental health; Margaret Satterthwaite, the special rapporteur on the independence of judges and lawyers; and Ben Saul, the special rapporteur on protection of rights and freedoms while countering terrorism.
