Why this matters now
CAA is among the most-debated laws of the decade. Tested for the religion-based eligibility criteria, exclusion of Muslims, exemption of North-East under Sixth Schedule + Inner Line Permit, the SC challenges (Indian Union Muslim League et al.), and the March 2024 Rules notification.
Context: Citizenship Act 1955 baseline
The Citizenship Act 1955 provides for acquisition of Indian citizenship by birth, descent, registration and naturalisation. Naturalisation normally requires 11 years of residence (out of preceding 14). CAA 2019 reduces this to 5 years for the specified communities and countries.
Key provisions
- Eligible communities: Hindu, Sikh, Buddhist, Jain, Parsi and Christian — six communities.
- Eligible countries: Pakistan, Bangladesh, Afghanistan — three communities.
- Arrival cut-off: on or before 31 December 2014.
- Residence reduced: 11 years → 5 years.
- Definition of “illegal migrant” in § 2(1)(b) of the Citizenship Act 1955 amended to exclude this group.
- Exemptions: Sixth Schedule (Tribal Areas) of Assam, Meghalaya, Mizoram, Tripura; Inner Line Permit regime under Bengal Eastern Frontier Regulation 1873 in Arunachal Pradesh, Mizoram, Nagaland, Manipur.
Constitutional challenges and 2024 Rules
Over 240 writ petitions are pending in the Supreme Court — lead petitioner the Indian Union Muslim League (IUML). Challenges centre on:
- Article 14 violation — religion-based classification.
- Article 21 violation — arbitrariness.
- Assam Accord 1985 violation — the Accord fixed 25 March 1971 as the citizenship cut-off for Assam; CAA extends it.
The Government framed the Citizenship Amendment Rules, 2024 on 11 March 2024 (4 years after passage, just before general election). Beneficiaries can now apply online through the indiacitizenshiponline.nic.in portal. SC has not stayed CAA implementation as of June 2026.
