The Essential Religious Practices test is a doctrine in search of its own limits

This article is critical for UPSC Mains as it examines the evolution and constitutional validity of the Essential Religious Practices (ERP) test—a doctrine central to India's fundamental rights jurisprudence under Articles 25-26. The piece traces the doctrine's journey from the modest Shirur Mutt case (1954) through Venkataramana Devaru (1958) to its current confrontation with constitutional morality. For prelims, the landmark cases cited (Shirur Mutt, Sabarimala 2018, Navtej Johar 2018) and the textual architecture of Article 25(1) being subject to Articles 14, 15, and 21 are testable. The ongoing nine-judge bench hearing represents the most significant constitutional development on religious freedom in decades, making this essential for both state PSCs (OPSC, BPSC) and UPSC aspirants covering federalism, secularism, and judicial review.

  • The nine-judge Constitution Bench in Kantaru Rajeevaru v Indian Young Lawyers' Association is hearing the Sabarimala review, inheriting a 70-year-old judicial doctrine on Essential Religious Practices (ERP)
  • The ERP doctrine originated in Commissioner, Hindu Religious Endowments, Madras v Sri Lakshmindra Thirtha Swamiar of Shirur Mutt (1954), where the Court ruled that freedom of religion under Article 25 covers both belief and practice
  • In Sri Venkataramana Devaru v. State of Mysore (1958), Justice Venkatarama Aiyar established the Court's role in determining what constitutes 'essential' practice, moving away from complete deference to religious communities

The fear around Mythos is also self-serving AI hype. For India, safety might lie in more open source resources

This article tests understanding of India's cybersecurity policy and digital sovereignty in the AI era. For Prelims, it could ask about Mythos, Project Glasswing, or open-source AI advantages. For Mains, it directly maps to technology policy, national security, and self-reliance (Atmanirbhar Bharat) in critical infrastructure. The article argues that India's reliance on proprietary US AI models for cyber-defence compromises digital sovereignty, making it testable under government policy and strategic autonomy. The open-source vs proprietary debate in AI aligns with broader questions about technology dependency.

  • Anthropic's proprietary LLM Mythos has been deemed "too dangerous to release" because it discovers security vulnerabilities in software
  • Under Project Glasswing, Anthropic provided exclusive access to US government and select American software companies to uncover and patch vulnerabilities
  • Mythos found vulnerabilities in Linux, OpenBSD, and Firefox but required thousands of attempts and $100 million (Anthropic has set aside $100 million for the project)

India’s first green methanol plant to turn Kutch’s most invasive weed into marine fuel

This story combines environmental治理 (invasive species management), science (green methanol production technology), and international policy (IMO green fuel mandates) — making it relevant across multiple UPSC syllabus areas. Prelims could test the invasive species fact or IMO mandate, while Mains could examine India's bioeconomy approach to environmental challenges or the intersection of climate policy with biodiversity conservation. The Gujarat-specific angle also makes it relevant for state-level examinations.

  • Prosopis juliflora is ranked among the world's top 100 invasive species and has threatened biodiversity in Kutch's Banni grasslands for decades
  • The shrub, introduced by the British in the 1920s and by Gujarat forest department in 1961 to halt salt desert encroachment in Rann, crowded out native grasses over thousands of kilometres
  • India's first green methanol production plant will use this invasive weed as feedstock to produce fuel for ocean-going ships
