Subtopic: Indian Economy · mandatory CSR and corporate governance reform
Show model answer outline
Introduction (Companies Act 2013 and CSR as inclusive-growth strategy) → the CSR mandate under Section 135 → implementation challenges → other key reform provisions and their implications → Conclusion
Key points- Section 135 mandates CSR for companies with net worth >= Rs 500 cr, or turnover >= Rs 1,000 cr, or net profit >= Rs 5 cr.
- Such firms must spend 2% of the three-year average net profit on Schedule VII activities via a board CSR committee.
- Challenges: definitional ambiguity, tokenism/greenwashing, tick-box compliance and weak impact measurement.
- Geographic concentration near operations leaves backward areas neglected; monitoring and reporting remain weak.
- Original 'comply or explain' model was tightened by later amendments — unspent funds transferable to specified funds, with penalties.
- Other reforms: class-action suits, statutory SFIO, independent directors, mandatory woman director, auditor rotation.
- NFRA strengthens audit oversight; One Person Company (OPC) formalises small business — implication: better governance and investor protection.

Subtopic: Indian Economy · public-private partnerships in infrastructure
Show model answer outline
Introduction (PPP and the infrastructure financing gap) → pros of the model → cons and criticisms → reforms to make PPP viable → Conclusion
Key points- PPP models (BOT toll/annuity, DBFOT, Hybrid Annuity Model, TOT) mobilise private capital and expertise for public infrastructure.
- Pro: bridges the fiscal/resource gap for highways, airports, ports and metros the exchequer cannot fund alone.
- Pro: allocates risk to the party best able to bear it and rewards efficiency, innovation and timely delivery.
- Con: over-optimistic bidding and traffic forecasts cause stalled projects, renegotiation and stressed assets (highways, power).
- Con: 'private profit, public risk' when losses are socialised; high user charges burden citizens.
- Con: information asymmetry, weak contracts and poor dispute resolution mechanisms.
- Reforms: Kelkar Committee (2015) on risk-sharing and regulation; HAM, Viability Gap Funding, InvITs and PM Gati Shakti to revive PPP.

Subtopic: Indian Economy · rationale and delay of the Goods and Services Tax
Show model answer outline
Introduction (GST as India's biggest indirect-tax reform) → rationale for introduction → reasons for the long delay → resolution and Conclusion
Key points- GST removes the cascading 'tax on tax' effect via a continuous input tax credit chain.
- It subsumes multiple central and state indirect taxes into 'One Nation, One Tax', creating a common national market.
- It widens the base, boosts compliance through GSTN technology, cuts logistics costs and eases doing business.
- It institutionalises cooperative federalism via the GST Council under Article 279A.
- Delay cause 1: Centre-state trust deficit over revenue-loss compensation and the compensation formula.
- Delay cause 2: need for a constitutional amendment (101st Amendment Act, 2016) requiring broad political consensus.
- Delay causes 3-4: disputes over revenue-neutral rate, dual control, thresholds, and exclusion of petroleum and alcohol; plus GSTN readiness. Rolled out 1 July 2017.

Subtopic: Science & Technology · Section 3(d), patents and the Novartis Glivec case
Show model answer outline
Introduction (2005 patent amendment and TRIPS compliance) → circumstances forcing Section 3(d) → the Novartis / Glivec judgement → pros and cons of the decision → Conclusion
Key points- TRIPS obliged India to introduce pharmaceutical product patents (from process-only under the 1970 Act) by 2005.
- To prevent 'evergreening' and protect generic access, the Patents (Amendment) Act, 2005 inserted Section 3(d).
- Section 3(d): a new form of a known substance is not patentable unless it demonstrates enhanced therapeutic efficacy.
- Novartis AG v. Union of India (2013): SC upheld rejection of the patent on the beta-crystalline form of imatinib mesylate (Glivec).
- Pro: safeguarded affordable generic cancer drugs, public health and the right to health under Article 21.
- Pro: curbed evergreening; reinforced India as the 'pharmacy of the developing world'.
- Con: innovators argued it deters incremental innovation and weakens R&D investment and the IP environment; balanced via TRIPS flexibilities and the Doha Declaration.

Introduction: define UDRS/DRS → components (Hawk-Eye, Hot Spot, Snickometer, ball-tracking) → decision workflow → how silicone tape defeats Hot Spot → Conclusion: limits of technology
Key points- DRS lets players review and third umpire re-examine on-field decisions using technology
- Ball-tracking (Hawk-Eye) predicts trajectory for LBW: pitching, impact, wicket zone
- Hot Spot uses infra-red cameras to detect frictional heat of bat/pad contact
- Snickometer/UltraEdge correlates audio spikes with the moment of contact
- Silicone/insulating tape on the bat edge suppresses frictional heat, defeating Hot Spot
- Audio (Snicko) can still catch an edge that Hot Spot misses, hence cross-verification
- On-field umpire retains primacy; DRS only corrects clear errors
