PYQ Relevance:
[UPSC 2024] Despite comprehensive policies for equity and social justice, underprivileged sections are not yet getting the full benefits of affirmative action envisaged by the Constitution. Comment.
Linkage: The article explicitly states that “any argument against government control of temple affairs would be striking at the root of social justice”. This question directly addresses “social justice” and the upliftment of “underprivileged sections,” which is the core argument of the article “social justice model” enabled by the regulation of temple funds. |
Mentor’s Comment: A political controversy in Tamil Nadu emerged over using temple funds to build colleges. The debate highlights a unique social justice model rooted in colonial-era laws, notably the Tamil Nadu Hindu Religious and Charitable Endowments Act, 1959, which legally permits such use of surplus funds. The issue reflects ongoing tensions between secular governance, social reform, and religious traditions.
Today’s editorial analyses the Issues related to temple funds like to build colleges. This topic is important for GS Paper I (Indian Society) and GS Paper II (Social Justice) in the UPSC mains exam.

Let’s learn!
Why in the News?
A political controversy recently erupted in Tamil Nadu over the use of temple funds for building colleges.
What is the origin and evolution of state control over temples in Tamil Nadu?
- Colonial Intervention and Legal Frameworks: The British colonial government began regulating temples through laws such as the Madras Regulation VII of 1817 and the Religious Endowments Act, 1863. These aimed at curbing mismanagement and ensuring proper use of temple revenues, though actual control was minimal.
- Madras Hindu Religious and Charitable Endowments (HRCE) Act, 1927 & 1951: Post-independence, the Madras HRCE Act, 1951 granted the state direct control over temple administration. It replaced hereditary trustees with government-appointed officers, shifting from oversight to active state involvement in managing temple affairs.
- Dravidian Politics and Reformist Push: The Self-Respect Movement and the rise of Dravidian parties (e.g., DMK) advocated for rationalism and secular administration of temples. This reinforced the idea of temples as public institutions, furthering state oversight in their functioning.
Why is using temple funds for education legally and socially justified?
- Legal Provision under State Law: The Tamil Nadu Hindu Religious and Charitable Endowments (HR&CE) Act, 1959 allows the use of temple surplus funds for public purposes like education, healthcare, and social welfare, provided the core religious functions are not affected. Eg: The government used temple funds to construct colleges in Tiruvannamalai and Krishnagiri, serving backward districts.
- Social Justice and Inclusive Development: Tamil Nadu follows a Dravidian model that sees temples as public institutions capable of promoting equality, education, and empowerment, especially for marginalized communities. Eg: Building a college with temple funds in a remote area helps first-generation learners, aligning with constitutional goals of equity and social upliftment.
- Historical and Cultural Precedent: In the pre-colonial and colonial era, temples often served as centres of learning and charity. Using their resources for education today revives that tradition in a modern, secular context. Eg: In the 19th century, temple lands supported gurukuls and feeding centres, a legacy extended now through modern institutions.
How did the Self-Respect Movement shape temple governance?
- Challenged Brahminical Control: The movement, led by Periyar E.V. Ramasamy, questioned hereditary priesthood and the dominance of Brahmins in temple administration, pushing for non-Brahmin inclusion in both ritual and managerial roles.
- State Intervention in Temple Administration: It laid the ideological foundation for government regulation of temples through legislations like the HR&CE Act, bringing temples under state control to ensure transparency, social equity, and public accountability.
- Promotion of Secular and Social Justice Values: The movement emphasized that temple wealth should serve the public good, such as education, healthcare, and social welfare, especially for the oppressed castes, transforming temples into instruments of social reform.
What are the constitutional and legal bases for state intervention in religious institutions in India?
- Article 25(2)(a) – Social Welfare and Reform: The Constitution permits the state to regulate or restrict any economic, financial, political, or secular activity associated with religion to promote social welfare and reform.
- Article 26 – Regulates While Protecting Rights: While religious denominations have rights to manage their own affairs, the state can impose reasonable restrictions in the interest of public order, morality, and health.
- Judicial Precedents and Statutory Laws: Courts have upheld state control over temples (e.g., in Shirur Mutt case) distinguishing between religious practices and secular administration. Laws like the Hindu Religious and Charitable Endowments (HR&CE) Act legally enable such oversight.
|
Should religious institutions be allowed to function autonomously without state control?
-
- Protection of Religious Freedom: Article 26 of the Indian Constitution grants religious denominations the right to manage their own affairs. Autonomy respects the pluralistic ethos of India and avoids state overreach in spiritual matters.
-
- Cultural and Traditional Integrity: Many religious institutions have centuries-old customs and management systems. Autonom y helps preserve these indigenous practices without interference from changing political or administrative interests.
-
- Accountability and Transparency: Without state oversight, there is a higher risk of financial mismanagement, corruption, or exploitation of devotees. State regulation ensures proper audit and governance of temple funds and assets.
- Public Interest and Welfare: Religious institutions often hold significant wealth and influence. State control can direct surplus resources towards social welfare, education, and infrastructure, promoting inclusive development beyond the religious community.
Way forward:
- Balanced Autonomy with Regulation: Implement a co-governance model where religious institutions retain spiritual autonomy, while the state ensures financial transparency, protection of heritage, and equitable use of public funds.
- Strengthen Legal Frameworks: Update existing laws to clearly define the limits of state intervention, ensure community representation in temple boards, and establish robust grievance redressal mechanisms.

Why in the News?
India is in the spotlight as recent UNCTAD data reveals a significant decline in net FDI inflows, falling to a 15-year low in FY24, even though gross inflows remain strong.
What are the key reasons behind the global decline in FDI flows, particularly to EMDEs?
- Geopolitical Instability: Rising geopolitical tensions such as the Russia-Ukraine war, Middle East conflicts, and US-China rivalries have weakened investor confidence, especially in Emerging Markets and Developing Economies (EMDEs) due to increased risk perception. Eg: After the Ukraine war, many European investors pulled out from Eastern European nations due to security concerns.
- Protectionist Policies: Countries have adopted more protectionist measures, including tighter FDI regulations, screening laws, and withdrawal from bilateral investment treaties (BITs), limiting foreign investor access. Eg: India terminated several Bilateral Investment Treaties post-2016, including with the Netherlands and Germany, leading to investor uncertainty.
- Supply Chain Realignment: Due to disruptions from the COVID-19 pandemic and rising geopolitical tensions, companies are shifting towards nearshoring and friend-shoring, bypassing many EMDEs. Eg: Several U.S. firms moved manufacturing from China to Mexico or Vietnam rather than to India or African countries.
Why has India experienced a sharp fall in net FDI despite rising gross inflows?
- High Repatriation of Earnings: While gross FDI inflows have increased, foreign investors are repatriating more profits, dividends, and disinvestments, leading to a decline in net FDI. Eg: In FY24, gross inflows were around $71 billion, but outflows (disinvestment/repatriation) rose sharply, reducing net FDI to $10.6 billion.
- Increased Disinvestment by Foreign Investors: Foreign companies have sold off stakes or exited Indian ventures due to regulatory uncertainties or global consolidation strategies. Eg: Vodafone’s reduction in stake in Vodafone Idea and exits by foreign private equity firms.
- Shift in Investment Strategy: There is a growing trend toward private equity and venture capital, which often involves short-term investments and quicker exits compared to traditional FDI. Eg: Start-up funding peaked in 2021–22 but many investors exited via IPOs or mergers within 2–3 years.
How can trade agreements and FTAs boost India’s FDI inflows and global integration?
- Market Access and Investor Confidence: Trade agreements and FTAs offer preferential market access, reduce tariff and non-tariff barriers, and provide a stable regulatory environment, encouraging foreign investors. Eg: The India-UAE CEPA (2022) led to a 34% rise in bilateral trade and boosted UAE investments in sectors like logistics and infrastructure.
- Integration into Global Value Chains (GVCs): FTAs help India plug into regional and global supply chains, making it a more attractive hub for FDI in manufacturing and exports. Eg: The India-ASEAN FTA improved electronics and automobile component exports, drawing FDI from Japan and South Korea into India.
- Legal and Dispute Resolution Frameworks: Comprehensive FTAs often include investment protection clauses and dispute resolution mechanisms, which reduce investor risk and boost inflows. Eg: India’s negotiation of Investment Protection Agreements (IPAs) with the EU has raised interest among European investors in clean energy and pharma.
Why is state-level reform crucial in India’s strategy to enhance FDI inflows?
- Ease of Doing Business at Ground Level: State-level reforms simplify land acquisition, labour regulations, and approval processes, making local environments more investor-friendly. Eg: Andhra Pradesh ranked top in the Business Reforms Action Plan (BRAP) 2020 for streamlining industrial approvals and digitizing services.
- Sector-Specific Policy Innovation: States can tailor sectoral incentives, infrastructure, and skill policies to attract targeted FDI in areas like textiles, electronics, or renewable energy. Eg: Tamil Nadu’s Electric Vehicle Policy attracted investments from Ola Electric and Hyundai in the EV sector.
- Healthy Inter-State Competition: Reform-oriented states create competitive pressure, encouraging others to improve investment climates, creating a national uplift in FDI appeal. Eg: Gujarat’s proactive approach in renewable energy prompted states like Rajasthan to fast-track their solar park approvals.
Way forward:
- Institutionalize Competitive Federalism: Strengthen the ranking framework for states based on FDI-related reforms (like BRAP), and link a portion of central incentives or grants to reform performance.
- Build State-Capacity for Investor Facilitation: Enhance training for state-level bureaucrats, establish single-window clearance systems, and promote public-private dialogue platforms to address investor concerns proactively.
Mains PYQ:

Why in the News?
The U.S. has designated The Resistance Front (TRF), which claimed responsibility for the Pahalgam terror attack (April 2025), as a Foreign Terrorist Organization (FTO) and Specially Designated Global Terrorist.
What is the impact of the U.S. designating TRF as an FTO on global counterterrorism?
- Legitimizes India’s concerns: The U.S. acknowledgment of TRF’s role in the Pahalgam terror attackstrengthens the global consensus on cross-border terror threats.
- Links to Lashkar-e-Taiba (LeT): The U.S. designation of TRF as a front/proxy of LeT exposes the continued existence of banned groups under new names.
- Strengthens international action: The move could help India push for sanctions against TRF at the UN’s 1267 Sanctions Committee, boosting transnational legal cooperation.
Why is Pakistan’s claim about LeT being defunct questionable?
- TRF’s Linkage with LeT: The U.S. designation of The Resistance Front (TRF) as a “front and proxy” for Lashkar-e-Taiba (LeT) proves that LeT continues to operate under new aliases, despite Pakistan’s claims of dismantling the group. Eg: TRF claimed responsibility for the 2025 Pahalgam attack, showing LeT’s continued operational role.
- Continued Terror Activities: Despite LeT’s inclusion in the U.S. Foreign Terrorist Organization (FTO) list since 2001, it has repeatedly executed attacks in India, reflecting its persistent capabilities. Eg: The 2008 Mumbai attacks and later cross-border infiltrations have been linked to LeT-trained cadres.
- International Endorsement Missing: Pakistan’s claim lacks credible global validation. Instead, it has been seen shielding TRF at the UN Security Council (UNSC), undermining its own narrative. Eg: TRF’s name was excluded from the UNSC resolution on the Pahalgam attack, reportedly due to Pakistani lobbying.
How does the U.S. response post-Pahalgam reveal contradictions in its policy?
- Mixed messaging: While designating TRF is a positive step, claims by the Trump administration about mediating a ceasefire and nuclear de-escalation dilute India’s counter-terror narrative.
- Diplomatic inconsistency: Praise for Pakistan’s military chief shortly after India clarified its stance reflects a lack of consistent pressure on Pakistan to curb terrorism.
- Missed opportunity at UNSC: The U.S. initially allowed TRF to be left out of the UNSC resolution, showing conflicting priorities between diplomacy and counterterrorism.
What blocks India’s effort to sanction the TRF at the UNSC?
- Veto Power Politics: The UN Security Council’s 1267 Committee requires unanimous consent among P-5 members for sanctions. Some permanent members, especially China and the U.S., have previously withheld support or yielded to Pakistan’s pressure, blocking India’s proposals. Eg: TRF’s name was omitted from the UNSC resolution on the 2025 Pahalgam attack.
- Pakistan’s Diplomatic Shielding: Pakistan continues to lobby against designations of terror outfits like TRF, masking them as defunct or rebranded groups, and frames them as indigenous resistance, making it harder for India to gain international consensus.
How should India strengthen its anti-terror diplomacy? (Way forward)
- Build Strategic Alliances and International Pressure: India should deepen counter-terrorism cooperation with key countries like the U.S., France, and the UK, while mobilizing regional blocs (e.g., QUAD, BRICS) to collectively push for sanctioning terror groups at global forums like the UNSC 1267 Committee.
- Pursue Legal and Diplomatic Action Proactively: India must file strong dossiers with evidence linking terror fronts like TRF to banned outfits like LeT and pursue timely extraditions of wanted terrorists through bilateral treaties and Interpol. Eg: The extradition request for Tahawwur Hussain Rana reflects India’s resolve to hold perpetrators accountable.
Mains PYQ:
[UPSC 2024] Terrorism has become a significant threat to global peace and security’. Evaluate the effectiveness of the United Nations Security Council’s Counter-Terrorism Committee (CTC) and its associated bodies in addressing and mitigating this threat at the international level.
Linkage: The article explicitly mentions India’s hope that the U.S. designation of TRF will facilitate its designation at the UNSC under the 1267 Committee for sanctions, directly aligning with the question’s focus on international counter-terrorism mechanisms. This question directly pertains to the global challenge of terrorism and the role of international bodies like the UN Security Council.
