UNITED NATIONS: UN chief Antonio Guterres will not comment on India's Citizenship (Amendment) Bill while the domestic legislative process is still underway, his spokesperson has said, stressing the need to ensure that all governments pursue non-discriminatory laws.

The Lok Sabha passed the Citizenship (Amendment) Bill or CAB, which seeks to provide Indian citizenship to non-Muslim refugees coming from Pakistan, Bangladesh and Afghanistan after facing religious persecution there.

The Bill, which was passed in the Lok Sabha with 311 members favouring it and 80 voting against it, will now be tabled in the Rajya Sabha for its nod.

"As far as I'm aware, this is legislation that is continuing to go through the legislative process.

"So, we wouldn't have any comment while the domestic legislative process is being carried out," Guterres' Deputy Spokesman Farhan Haq said on Tuesday at the daily press briefing here.

Haq was responding to a question on whether the UN Secretary-General has any comment on the passage in the Lok Sabha of the Citizenship (Amendment) Bill, which the reporter said discriminates against Muslims.

"At the same time, you're aware of what our concerns are about making sure that all governments pursue non-discriminatory laws," Haq said.

According to the proposed legislation, members of Hindu, Sikh, Buddhist, Jain, Parsi and Christian communities, who have come from Pakistan, Bangladesh and Afghanistan, till December 31, 2014, facing religious persecution there, will not be treated as illegal immigrants but given Indian citizenship.
