CORE ISSUE Inflation risks (crude oil, weak monsoon, El Nino) now outweigh the case for easy money. KEY DETAILS • Repo rate: 5.25% to 5.50% • Stance: neutral to calibrated tightening, signals more hikes if price pressures persist • Forecasts: FY27 growth 7.1% (from 6.7%); inflation 5.2% (from 5.0%) • Impact: EMIs rise; banks raised EBLR by 25 bps WHY IT MATTERS Prelims: repo rate, MPC, policy stance, 4% (+/- 2%) inflation target.

Detention vs arrest: limits of police powers WHAT HAPPENED Opposition leaders, including Rahul Gandhi, were detained in Delhi on Oct 7 during a protest. CORE ISSUE Police can stop or remove people to prevent disorder, but the power cannot be arbitrary or a way around arrest safeguards. KEY DETAILS • Arrest: formal custody for an offence, starts criminal proceedings; detention: temporary, preventive hold • BNSS s.170: preventive arrest for cognisable offences • BNSS s.172: detain or remove a person defying a lawful direction; release within 24 hours in petty cases • BNSS s.163 prohibitory order imposed by Delhi Police on Oct 2 • Article 22; Joginder Kumar (1994), Arnesh Kumar (2014), Mazdoor Kisan Shakti Sangathan (2018) WHY IT MATTERS Prelims: Article 22, BNSS sections, landmark cases.

Pre & Mains Notes

1. GST process reforms: no arrest power, fewer notices, data-led compliance WHAT HAPPENED The 57th GST Council meeting, moved to Thursday (Oct 8), takes up process reforms - the second half of the overhaul that began with the September 2025 rate cuts. CORE ISSUE Can GST shift from arrest and leverage to civil recovery and data-driven compliance without weakening revenue protection? KEY DETAILS - Arrest: Proposal to remove GST officers' power to arrest; disputes settled through civil consequences - tax recovery, interest and penalty. - Prosecution: Stays available; threshold likely raised from Rs 1 crore to Rs 5 crore, minimum sentence removed, fine an option in every case. - Small notices: No notice where the amount is below Rs 10,000 (about a fifth of cases by number); likely to apply to pending cases too. - Redesign: Registration, returns, refunds and demands rebuilt on one principle - the system does what data can do, the officer handles what needs judgement. WHY IT MATTERS GST Council (Art. 279A), cooperative federalism and ease of doing business are repeat Prelims and Mains themes. Decriminalising tax offences is a likely Mains angle. GS Paper III - Economy: Indirect Taxes, GST Council, Ease of Doing Business 2. Nobel in Medicine 2026: optogenetics, controlling brain cells with light WHAT HAPPENED The 2026 Nobel Prize in Physiology or Medicine went to Karl Deisseroth, Peter Hegemann and Georg Nagel for finding an alga protein that reacts to light and using it as a switch to study nerve cells. CORE ISSUE How can neurons be switched on and off with light, and what does it mean for understanding the brain and for new therapies? KEY DETAILS - Optogenetics: Uses light to control genetically modified cells; a light-sensitive protein is expressed in the target cells. - Opsins: Light-sensitive proteins placed in specific cells act as switches that turn activity on or off. - Alga source: Chlamydomonas reacts within about 0.5 millisecond (human eye: 10 ms); channelrhodopsin-2 (ChR-2) detects and reacts to light. - Uses: Maps neural circuits for pain, social behaviour, thirst, food, reward, attention and memory formation. - Origin of idea: Francis Crick wanted to activate single nerve cells to study consciousness. WHY IT MATTERS Nobel-linked science and biotechnology tools are regular Prelims material. Useful for GS3 answers on neuroscience and genetic technologies. GS Paper III - Science & Technology: Biotechnology, Neuroscience
