The short answer

The Citizenship Amendment Act (2019) offers an accelerated path to Indian citizenship for Hindus, Sikhs, Buddhists, Jains, Parsis, and Christians who fled religious persecution in Pakistan, Bangladesh, and Afghanistan and entered India before December 31, 2014. Muslims from those countries are not included. Supporters call it humanitarian protection for minorities in Islamic states; opponents argue it violates Article 14's equality guarantee by making religion a criterion for citizenship.

The law became one of the most contested legislative acts of the Modi government. Nationwide protests followed, and several state governments declared they would not implement it, though the rules were finally notified, and the law came into effect, in March 2024.

Background

The idea of granting refuge to Hindu and Sikh refugees from Pakistan has been in BJP manifestos since the 1990s. After the 2019 Lok Sabha landslide, the government moved quickly. The amendment changed the Citizenship Act of 1955 by adding a proviso for the six religious communities and cutting the naturalisation period from 11 years to 5.

The Northeast became a flashpoint: the Assam Accord of 1985 had set a separate cut-off date for illegal immigrants of all religions in Assam, and tribal communities feared being swamped by Hindu Bengali immigrants from Bangladesh who would now be regularised.

The case for

  • Pakistan, Bangladesh, and Afghanistan are constitutionally Islamic states; their non-Muslim minorities face documented, systematic persecution.
  • India has a civilisational and humanitarian obligation to provide refuge to those communities, as Israel does for Jews.
  • Muslim citizens of India are not targeted; the law does not remove citizenship from anyone.

The case against

  • Article 14 of the Constitution guarantees equality before the law to 'any person', not just citizens; using religion as a criterion for citizenship eligibility arguably violates this.
  • Muslims fleeing persecution in Sri Lanka, Myanmar, or China are excluded without explanation, undermining the 'persecuted minorities' rationale.
  • When combined with the proposed nationwide NRC, critics feared CAA would give non-Muslim illegal immigrants a path to citizenship while Muslim ones would be left stateless.

How other countries handle it

Israel's Law of Return (1950) grants automatic citizenship to Jews worldwide, an acknowledged ethno-religious criterion. Germany's post-war Basic Law offered return-rights to ethnic Germans expelled from Eastern Europe. The difference critics draw is that India's Constitution explicitly prohibits discrimination on grounds of religion, which makes the CAA's framing uniquely contested in a way Israel's and Germany's laws were not for their respective constitutions.

Where the debate sits in Indian politics

The BJP frames the CAA as humanitarian and the protests as politically motivated. The opposition, most state governments in the south and east, and Muslim organisations argue it is a step toward defining India as a Hindu state. The Supreme Court challenge has not been finally decided.

What this measures on the compass

Your position on the CAA primarily moves the Tradition axis (secular vs. civilisational-religious identity in law) and the Nation axis (what the state owes to co-religionists abroad vs. equal treatment of all people on its territory).
