Kolkata, Dec 28 (IANS): The Justice Sushanta Chatterjee Commission, set up to probe the July 21, 1993, police firing in which 13 Congress workers were killed, will submit its report to the West Bengal government Monday.

"The report will be submitted to the government Monday," the retired Calcutta High Court judge said Sunday.

Police had opened fire after Youth Congress workers laid siege on the Writers' Buildings - the state secretariat - demanding that voters' identity cards be the sole document required for voting.

Immediately after assuming power in May 2011, the Mamata Banerjee-led Trinamool Congress government constituted the commission to ascertain who issued the order to police to open fire at the rally spearheaded by her, then a Youth Congress leader.

The commission has examined over 300 witnesses, including former chief minister Buddhadeb Bhattacharjee and Left Front chairperson Biman Bose.

Several Indian Police Service officers, including Tushar Talukdar who was the city police commissioner at the time of the incident, had challenged the validity of the commission before the Calcutta High Court.
