Speaking at an event in the capital, Menon claimed that the contentious Act "isolates us from the international community". He warned the government that "if we are changing the idea of India, we have to be ready for the consequences it brings along with it, too".
He was referring to the international scrutiny that India will be subjected to owing to this religion-based law.
The CAA benefits Hindu, Sikh, Jain, Buddhist, Christian and Parsi refugees from Afghanistan, Pakistan and Bangladesh who sought refuge in India before 2015. It excludes Muslims from these nations from availing the benefit of this constituitonal amendment
On the sidelines of the event, Jamia Milia ex-Vice Chancellor and former Delhi Lt. Governor Najib Jung too criticised the police for entering the Jamia university campus.
"This cannot be supported that cops will get inside a university. The students have shown great amount of restraint," he said.
Jung blamed the "lack of communication" for the protests against the CAA.
"Even the government has accepted there has been a lack of communication. Let them communicate well," he said.
On being asked whether he wants a roll back of the CAA, he replied: "All I am asking for is better communication on the CAA".
Apart from the two former officials, political scientist Zoya Hasan and activist Harsh Mander were also part of the discussions organised jointly by the Constitutional Conduct Group and Karwan e Mohabbet.
