El-Hibir was a member of an indictment council preparing a case in June 2019 against members of the previous government involved in the 1989 Sudanese coup d'état. Lawyers filed the case in May 2019, shortly after the April 2019 coup d'état that overthrew president Omar al-Bashir and prior to the Transitional Military Council transferring power to a mixed civilian–military Sovereignty Council several months later. The indictment council consisted of el-Hibir, Kamal el-Jazouli and Mohamed el-Hafiz. On 24 June 2019, the council questioned Sadiq al-Mahdi, the former prime minister overthrown by Omar al-Bashir in the 1989 coup, retired Lt-Generals Mahdi Babu Nimer and Fadlallah Burma.
