Tanrikulu is the leading human rights attorney in Turkish Kurdistan, a strong advocate of legal reform and strengthening civil society. Co-founder of the Diyarbakir Human Rights Association, the Secretary of the Bar Association in Diyarbakir, and the regional representative of the Human Rights Foundation of Turkey, his work has taken him where few dare to go.
For over a decade, the Kurdish region has been under a state of siege, including food blockades and curfews. Fighting between Turkish troops and the Workers Party of Kurdistan has caught civilians in the crossfire. Turkish forces engaged in a systematic practice of targeting civilians, destroying villages, and forcibly evicting noncombatants. More than twenty-six thousand people have been killed and two million displaced since 1992.
Extrajudicial killings, disappearances, arbitrary detention, and torture in police custody are commonplace. Freedom of expression is severely curtailed. Throughout Turkey and particularly in the southeast region, lawyers avoid defending politically unpopular clients.
In Diyarbakir alone, more than thirty lawyers have faced criminal charges apparently based solely on their defense of clients in the courts. Even submitting complaints to the European Court of Human Rights or passing information to international human rights groups has been considered evidence of terrorist support and has resulted in prosecutions and prison terms. Tanrikulu has been indicted several times for his activities as a lawyer and in 1994 was charged with "insulting the judiciary" for appealing a decision to convict on the basis of a statement ruled inadmissible by another court because it was extracted by torture.
Since 2010, he has served in the Turkish Grand Assembly.
