Timtik was part of a group of 18 lawyers arrested in September 2017.[3] They were all members of either the Progressive Lawyers Association (Turkish: Çağdaş Hukukçular Derneği, ÇHD) or the People’s Law Bureau (Turkish: Halkın Hukuk Bürosu), known for representing clients critical of the Turkish government.[4] In March 2019, they were found guilty of membership or association with the outlawed Revolutionary People's Liberation Party/Front (DHKP-C) and sentenced to lengthy prison terms.[5][6] Timtik was sentenced to 13 years and 6 months in prison and Aytaç Ünsal to 10 years and 6 months.[4] Milena Buyum, Amnesty International's senior campaign manager on Turkey called the convictions "a travesty of justice and demonstrate yet again the inability of courts crippled under political pressure to deliver a fair trial."[5] She called for the lawyers to be unconditionally released and for the convictions to be quashed.[5] In October, Timtik's appeal to the Istanbul Regional Court of Appeal was rejected and at the time of her death, her appeal to the Turkish Supreme Court was pending.[4]
