Coach S-6 of the Sabarmati Express, in which 59 people, mostly 'kar sevaks' returning from Ayodhya, were travelling, was burnt to death on February 27, 2002 at the Godhra station, triggering riots in the state.
The special SIT court had on March 1, 2011 convicted 31 people and acquitted 63 in the case. While 11 people were sentenced to death, 20 were given life in jail.
Later, several appeals were filed in the High Court challenging the conviction, while the state government had questioned the acquittal of 63 people.
The court had convicted 31 people while accepting the prosecution's contention that there was a conspiracy behind the incident.
Those acquitted included the prime accused, Maulana Umarji, the then president of Godhra Municipality Mohammad Hussain Kalota, Mohammad Ansari, and Nanumiya Chaudhary of Gangapur, Uttar Pradesh.
The Nanavati Commission, appointed by the Gujarat government to probe the carnage, had concluded that the fire in the S-6 coach was not an accident, but it was set ablaze.
