Supreme Court Dismisses PIL Against Caste Census: Government Must Know Backward Caste Numbers

The Supreme Court of India on May 20, 2026, dismissed a Public Interest Litigation challenging the Union Government's decision to conduct caste enumeration as part of the upcoming 2027 Census. A bench headed by Chief Justice of India Surya Kant, along with Justices Joymalya Bagchi and Vipul Pancholi, held that the collection of caste data is a policy decision falling squarely within the government's domain and that courts cannot intervene in such matters. The Court observed that the government must know the number of persons belonging to backward castes in order to frame effective welfare measures. The 2027 Census will be India's first to include comprehensive caste enumeration since 1931 and its first fully digital census.

What the Petitioner Argued Against Caste Census

The petitioner-in-person argued that the collection of caste data through the national Census posed significant risks. The primary concern raised was that caste data could be susceptible to misuse, particularly if such information were to fall into the hands of corporate entities and politicians who could exploit it for targeted marketing or electoral manipulation. The petitioner further contended that there was no constitutional or statutory justification for collecting caste data as part of the general population Census, and that such enumeration could deepen caste divisions rather than address them. The petition sought a direction to the Union Government to exclude caste-related questions from the Census questionnaire and to limit data collection to demographic, educational, and economic parameters.

Supreme Court's Reasoning: Policy Domain of the Government

The Supreme Court rejected the petition on the ground that the decision to conduct caste enumeration is a policy matter that lies within the executive's domain. The CJI-led bench held that the government needs accurate data on the number and distribution of backward castes to design and implement welfare schemes, reservation policies, and targeted development programmes. Without reliable caste data, the government would be framing policies in a vacuum. The Court noted that concerns about data misuse, while valid in principle, do not justify preventing the government from collecting information that is essential for evidence-based policymaking. The Census Act, 1948 grants the Central Government broad powers to determine what information is collected during the Census, and the judiciary has traditionally refrained from interfering with the content and methodology of census operations.

Historical Context: Why Caste Data Matters for Indian Policy

India last conducted a comprehensive caste census in 1931 during the British colonial era. While the post-independence Census has collected data on Scheduled Castes and Scheduled Tribes, it has not enumerated Other Backward Classes (OBCs) or forward castes. The Socio-Economic and Caste Census (SECC) conducted in 2011 attempted to fill this gap, but its caste data was never officially released due to concerns about data quality and methodological issues. The absence of reliable caste data has been a long-standing policy challenge. The Mandal Commission (1980), which recommended 27 per cent reservation for OBCs in government employment, relied on estimates rather than census data. Several state governments, including Bihar, have conducted their own caste surveys in recent years. The decision to include caste in the 2027 national Census represents a significant shift in policy, providing the first nationwide caste dataset in nearly a century.

Data Privacy and Safeguards Under the DPDP Act

The petitioner's concerns about data misuse intersect with India's evolving data protection framework. The Digital Personal Data Protection Act, 2023 (DPDP Act) and the DPDP Rules, 2025 establish obligations for data fiduciaries, including government agencies, to process personal data only for lawful purposes and with appropriate safeguards. Caste data constitutes sensitive personal information, and any government agency collecting and processing such data through the Census would be expected to comply with the DPDP framework. The Census Act, 1948 already contains confidentiality provisions under Section 15, which makes it a criminal offence for any census officer to disclose individual-level census information. These existing statutory safeguards, combined with the new data protection regime, provide multiple layers of protection against the kind of misuse the petitioner feared.

Key Takeaways

The Supreme Court has confirmed that conducting a caste census is within the government's policy prerogative and is not subject to judicial interference. The 2027 Census will be the first to include comprehensive caste enumeration since 1931, providing data that could reshape reservation policies, welfare targeting, and resource allocation across the country. The Court emphasized that the government needs backward caste data to frame effective welfare measures, reinforcing the administrative necessity of such enumeration. While data privacy concerns are legitimate, existing safeguards under the Census Act, 1948 and the DPDP Act, 2023 provide protections against misuse. The first fully digital census will present both opportunities for more accurate data collection and challenges in ensuring data security at scale.
