The fourth additional metropolitan sessions-cum-special court for NIA cases had concluded the trial and last week posted the case for judgement on April 16.
The blast at the historic Mecca Masjid here on May 18, 2007 during Friday prayers had also left 58 others injured.
After initial investigation by the local police, the case was transferred to the Central Bureau Of Investigation (CBI), which filed a charge sheet.
Subsequently, the National Investigation Agency (NIA) took over the case from the CBI in 2011.
Ten persons allegedly belonging to right-wing organisations were named as accused in the case.
However, only five of them -- Devendra Gupta, Lokesh Sharma, Swami Aseemanand alias Naba Kumar Sarkar, Bharat Mohanlal Rateshwar alias Bharat Bhai and Rajendra Chowdhary - were arrested and faced trial in the case.
A total of 226 witnesses were examined during the trial and as many as 411 documents were exhibited.
In March 2017, a court in Rajasthan had sentenced Gupta and another convict to life in jail in the Ajmer Dargah blast case.
