The Calcutta Quran Petition

Chakraborty wrote to the Secretary, Department of Home Government of West Bengal, demanding the ban of the Quran.

Chakraborty thereafter met Chandmal Chopra, who also wrote to the Department of Home Government of West Bengal on March 16, 1985.

Chandmal Chopra tried to obtain an order banning the Quran, by filing a Writ Petition at the Calcutta High Court on 29 March 1985.

The petition claimed that Sections 153A and 295A of the Indian Penal Code, and Section 95 of the Criminal Procedure Code were often used by Muslims to ban or proscribe publications critical of Islam, and stated that "so far it had been the privilege of the Peoples of the Book to ban and burn the sacred literature of the Pagans."

Chandmal Chopra thought that the Quran "on grounds of religion promotes disharmony, feeling of enmity, hatred and ill-will between different religious communities and incite people to commit violence and disturb public tranquility..." Chandmal Chopra also included a list of several dozens of Quran verses that "promote disharmony" in his petition.

On the contrary, they provide an almost exhaustive list of Allah’s sayings on a subject of great significance, namely, what the believers should believe about and do to the unbelievers..." The Telegraph of May 9, 1985 reported that the Union Government would make itself a party in the case, and the Union law minister Ashoke Sen and the attorney-general of the Government of India were going to take action against the case.

The Attorney-General of the Government of India and the Advocate-General of West Bengal appeared in the case and argued against Chopra's petition.

After the case was closed, the Chief Minister of Jammu and Kashmir, during a mass rally in Srinagar, demanded action against Justice Padma Khastgir who permitted the petition to be filed.
