  • Supreme Court Guidelines on DNA Evidence in Criminal Cases

    Why in the News?

    The Supreme Court has issued guidelines in the Kattavellai @ Devakar v. State of Tamil Nadu Judgement to standardise DNA handling in criminal cases to prevent contamination and delays after evidence lapses in a major case.

    Key Highlights of the Supreme Court Guidelines:

    • Case Context: It involved rape, murder, and robbery. Court flagged delays in Forensic Science Laboratory (FSL) submission, lack of chain of custody, and risk of contamination.
    • Need: Lack of uniform procedures across states despite scattered rules. Since Police and Public Order are in the State List, Supreme Court intervened for national uniformity.
    • Guidelines Issued:
      • Collection and Documentation: Samples must be packaged properly, labelled with FIR details, and signed by medical officer, Investigating Officer, and witnesses.
      • Transportation: Investigating Officer (IO) must deliver samples to FSL within 48 hours. Reasons for any delay must be recorded.
      • Storage Pending Trial: Packages cannot be opened or resealed without trial court approval.
      • Chain of Custody Register: Maintained until conviction or acquittal. IO responsible for explaining lapses.

    Previous SC Observations on DNA Evidence:

    • Anil v. Maharashtra (2014): DNA reliable only if laboratory procedures are maintained.
    • Manoj v. Madhya Pradesh (2022): DNA rejected as recovery was from open area with contamination risk.
    • Rahul v. Delhi (2022): DNA held inadmissible after being kept in police custody for two months.
    • Pattu Rajan v. Tamil Nadu (2019): DNA value depends on corroborating evidence; absence not fatal.
    • Sharda v. Dharmpal (2003): DNA test orders valid; no violation of Article 21.
    • Das @ Anu v. Kerala (2022): DNA not self-incrimination under Article 20(3). Section 53A CrPC permits collection in rape cases.

    Back2Basics: DNA Profiling

    • Overview: DNA profiling, also called DNA fingerprinting, is a forensic technique to identify individuals by analysing unique DNA regions, mainly Short Tandem Repeats (STRs).
    • How it works: Human DNA is 99.9% identical; the 0.1% variability forms the basis of personal identification.
    • Sources: DNA can be extracted from blood, semen, saliva, hair, bone, skin, or even “touch DNA.”
    • Processes: The process includes isolation, purification, amplification, visualization, and statistical comparison of DNA markers.
    • Methods:  miniSTRs and mitochondrial DNA (mtDNA) help in degraded or limited samples.
    • Legal Status: Treated as expert opinion under Indian Evidence Act Section 45 (now BSA 2023 Section 39). DNA is corroborative, not substantive evidence.

  • [15th September 2025] The Hindu Op-ed: Improving Macros: Period of low inflation and relatively high growth

    PYQ Relevance

    [UPSC 2019] Do you agree with the view that steady GDP growth and low inflation have left the Indian economy in good shape? Give reasons in support of your arguments.

    Linkage: The present scenario of low inflation (2.1%) coupled with high growth directly resonates with the 2019 PYQ, as it exemplifies how such a macro mix strengthens household purchasing power and policy space. However, just as in 2019, questions about data reliability and sustainability remain valid. Thus, India’s current economic outlook offers both affirmation and nuance to the earlier debate.

    Mentor’s Comment

    India’s macroeconomic trajectory has taken a remarkable turn, shifting from the troubling “low growth, high inflation” trap of last year to a far more favorable “high growth, low inflation” outlook. With inflation dipping within RBI’s comfort band and food prices contracting sharply, the macro story is compelling and holds lessons for India’s policy and global positioning. This article unpacks the nuances of the recent data, explores what it means for the future, and situates it within the UPSC Mains framework with value addition, practice questions, and micro-themes.

    Introduction

    The August 2025 retail inflation numbers marked a critical juncture in India’s economic narrative. Retail inflation, though it rose slightly, stood at 2.1%, comfortably within the Reserve Bank of India’s (RBI) target range of 2%-6%. This snapped a nine-month declining streak but did not trigger alarm. Food inflation remained subdued, with striking contractions of 15.9% in vegetable prices and 14.5% in pulses. Combined with welfare provisions under the National Food Security Act, this ensured affordability of essential items. With low inflation across housing, fuel, and clothing, India’s macroeconomic picture looks vastly different from last year, when high inflation coupled with low growth defined the economic outlook. The gap between growth and inflation has widened from 2.1 percentage points last year to 5.5 percentage points now—an enviable reversal.

    Understanding the Current Inflation Trends

    1. Retail inflation at 2.1%: Marginally within RBI’s comfort zone of 2%-6%, reflecting stability despite global uncertainty.
    2. Food prices contracting sharply: Vegetables fell by 15.9% and pulses by 14.5%, easing household expenditure.
    3. Other necessities stable: Housing, clothing, footwear, and fuel inflation are all lower in August than in July.
    4. Welfare cushioning: Free foodgrains under the NFSA ensure food affordability despite global volatility.

    How Has the Macro Picture Changed Since Last Year?

    1. From high inflation to low inflation: Inflationary pressures last year eroded purchasing power, but now they remain subdued.
    2. From sluggish growth to robust growth: Growth has accelerated, giving policymakers breathing room.
    3. Growth–inflation differential widened: From 2.1 percentage points last year to 5.5 points this year, a striking macro improvement.
    4. Comparability holds: Concerns about data integrity existed last year too, hence the relative improvement is valid.

    What Role Do Global and Domestic Policies Play?

    1. Russian oil purchases: Even if India abandons Russian crude under U.S. pressure, the inflationary impact will be limited due to already-low global crude prices.
    2. GST rate cuts: Effective September 22, lower GST rates are expected to reduce consumer prices further.
    3. RBI’s cautious optimism: While Q1’s low inflation-high growth dynamic raises hopes of a rate cut, global uncertainties may push this decision to December instead of September.

    What Lies Ahead for India’s Economic Outlook?

    1. Benign inflation trajectory: Indicators point to sustained price stability.
    2. Limited global oil shock risk: Declining discounts from Russia and stable crude prices mean less volatility for India.
    3. Prospects for rate cuts: The Monetary Policy Committee may consider easing monetary policy in December, enhancing growth.
    4. Strengthened fiscal space: Low inflation allows government welfare and investment measures to operate without inflationary spirals.

    Conclusion

    India’s macroeconomic outlook in 2025 is a story of resilience and reversal. The sharp transition from a vulnerable high-inflation, low-growth setup to a robust high-growth, low-inflation phase underscores effective price stabilization and cushioning mechanisms like NFSA. While global uncertainties remain, the benign inflation trajectory coupled with strong growth provides a foundation for India’s economic policy to focus on sustainable and inclusive development.

    • Benefits: Adds ~₹200 crore annually to Assam’s rural economy; supports farmers and tribal communities with assured markets.
    • Policy Enabler: Reclassification of bamboo (no longer a tree) allowed free cultivation and harvesting, unlocking industrial potential.

    Back2Basics: Regulation of Bamboo in India

    • Earlier Status: The Indian Forest Act, 1927 classified bamboo as a “tree”, though botanically it is a grass.
    • Regulatory Impact: Even in non-forest areas, felling, cutting, and transport of bamboo required permits like timber, discouraging farmers and traders.
    • 2017 Amendment: The Act was amended to remove “bamboos” from the definition of “tree” under Section 2(7), but only for non-forest areas.
    • Policy Goal: Intended to ease regulatory burdens, promote bamboo cultivation and trade, and strengthen agroforestry.
    • Current Rule: Bamboo on private/agricultural land can now be freely grown, cut, and transported without permits; bamboo in forest areas remains regulated.
    • Scientific Alignment: Recognises bamboo correctly as a grass (Poaceae family).
    • Significance: Supports rural farmers, artisans, and tribal communities by making bamboo a viable cash crop.

      • Manki: Head of pidh (cluster of 8–15 villages), adjudicates inter-village disputes.
    • Pre-British: Purely internal self-rule, no taxation or external sovereign authority.
    • British Codification:
      • Wilkinson’s Rules (1833–37) codified system into 31 rules, formally recognising Mankis/Mundas as British agents.
      • Introduced private property; Ho became raiyats (tenants) instead of communal landholders.
      • Led to demographic influx of dikkus (outsiders), rising from ~1,500 (1867) to ~15,700 (1897).
    • Post-Independence: Kolhan Government Estate dissolved (1947) but Wilkinson’s Rules still operative; Kolhan largely exempt from civil laws.
    • Judicial View: In Mora Ho vs State of Bihar (2000), Patna HC treated Wilkinson’s Rules as customs, not law, but upheld their continuance.
    • Current Practice: System governs village disputes; ~200 vacant posts filled by Gram Sabhas.
    • Criticism: Hereditary leadership limits efficiency; many leaders lack education for modern administration.
    • Reform Debate: Youth demand limiting hereditary succession and inclusion of non-tribal raiyats.
    • Contemporary Role: Remains a symbol of tribal autonomy yet requires modernisation for democratic governance.
