The Citizenship Amendment Act (CAA) of 2019, operationalized in full during 2024-25, continues to generate significant constitutional and humanitarian discourse. The Act amends the Citizenship Act, 1955, to fast-track citizenship for persecuted religious minorities from Pakistan, Afghanistan, and Bangladesh—specifically Hindus, Sikhs, Christians, Buddhists, and Parsis—who entered India before December 31, 2014.

Simultaneously, the proposed National Register of Citizens (NRC) aims to create an official national register documenting all lawful citizens. The NRC, first implemented in Assam in 2019, excluded approximately 1.9 million residents, rendering them stateless or undocumented. Critics argue that the CAA-NRC combination creates a dangerous asymmetry: while the CAA provides expedited citizenship pathways for specific religious groups from neighboring countries, the NRC can strip citizenship from long-term residents, particularly Muslims in India, who lack sufficient documentation.

The constitutional concern centers on Article 14 (equality before law) and Article 15 (non-discrimination on grounds of religion). Petitioners contend that CAA violates these provisions by discriminating on religious grounds—offering refuge to religious minorities from three countries while excluding Muslim minorities from the same countries. The government argues CAA addresses religious persecution, which is a legitimate state objective.

Statelessness poses acute challenges. The 2024-25 academic year saw increased documentation of individuals caught between CAA's narrow scope and NRC's stringent verification requirements. Children born to undocumented parents face barriers in school enrollment, healthcare access, and voting rights. International bodies, including UNHCR, have expressed concern about creating new categories of stateless persons in South Asia.

The constitutional courts remain seized of multiple petitions. In September 2024, the Supreme Court declined to admit a batch of pleas challenging CAA's constitutionality, citing pendency of another batch. Meanwhile, ground-level implementation reveals administrative challenges: proving religious persecution requires substantial evidence; documentation standards vary across states; and appeals mechanisms remain slow.

Civil society organizations have documented cases of individuals wrongfully excluded from NRC and unable to access CAA protections due to religious identity or missing documentation. The intersection of CAA and NRC thus raises fundamental questions about statelessness, constitutional rights, and the state's duty to recognize all residents as rights-bearing subjects. As of 2025, the legal and humanitarian dimensions remain unresolved, with vulnerable populations experiencing tangible restrictions on education, employment, and political participation.
