Prof. Ibrahim Hamis Juma (born 1958) is the 6th Chief Justice of the United Republic of Tanzania. A deeply respected legal scholar and former university professor, he was appointed to the highest judicial office by the late President John Magufuli in 2017. Before ascending to the Supreme Court, Prof. Juma built a formidable academic reputation as the Dean of the Faculty of Law at the University of Dar es Salaam and served as the Chairman of the Law Reform Commission of Tanzania. As Chief Justice, Prof. Juma has been the primary architect of the Tanzanian Judiciary's modernization. He aggressively pushed for the integration of ICT in court processes (e-judiciary), virtual hearings, and the reduction of massive case backlogs. However, his tenure has required navigating incredibly treacherous political waters. During both the 2020 and 2025 general elections, the judiciary faced immense pressure from civil society and the opposition, who accused the courts of rubber-stamping executive overreach and dismissing high-profile electoral and treason petitions (such as the detention of Tundu Lissu). Despite these criticisms, he maintains a steady, academically grounded grip on the nation's judicial branch.
