Pre & Mains Notes

1. Delhi Gymkhana Club land row WHAT HAPPENED • Centre’s L&DO asked Delhi Gymkhana Club to vacate its Safdarjung Road premises, citing “public purpose” and strategic infrastructure needs. ISSUE • Government powers over leasehold land in Delhi and interpretation of “public purpose”. KEY DETAILS • Delhi land largely administered by the Centre through the Land & Development Office (L&DO). • Club operates on colonial-era lease agreements; L&DO invoked a clause allowing “re-entry” of land for public purpose. • Area lies near key government and security establishments, including PM residence zone. • Many Delhi properties shifted from leasehold to freehold after 1947, but several institutional lands remain under old lease structures. • Constitutional context: Art. 300A → property can be deprived only by authority of law. WHY IT MATTERS • Highlights tensions between elite land use and public infrastructure priorities. • Shows continuing legacy of colonial property arrangements in Delhi. • Important for urban governance, land policy, and state control over public land. 2. Rajya Sabha defections and anti-defection law WHAT HAPPENED • AAP’s claim that two-thirds of its Rajya Sabha MPs could merge with another party revived debate on the merger exception under the anti-defection law. ISSUE • Whether legislators alone can trigger a valid “merger” under the Tenth Schedule. KEY DETAILS • Anti-defection law added through the 52nd Constitutional Amendment (1985) under the Tenth Schedule. • Split exception removed by 91st Constitutional Amendment (2003); merger exception remains. • Paragraph 4 allows exemption if 2/3 legislators merge with another political party. • Core debate: does merger require approval of the original political party organisation too? • Important cases: - Kihoto Hollohan (1992) → upheld anti-defection law. - Subhash Desai case (2023) → political party organisation, not just legislative wing, matters. WHY IT MATTERS • Impacts stability of coalition and party politics. • Raises questions about inner-party democracy and legislative autonomy. • Could shape future interpretation of defections in Parliament and Assemblies. 3. Indonesia’s export policy shift WHAT HAPPENED • Indonesia proposed routing exports of major commodities through a state-run agency, deepening its resource-nationalism strategy. ISSUE • Increasing state control over natural-resource exports and its global economic impact. KEY DETAILS • Policy may centralise exports of palm oil, coal, nickel and ferronickel through state agency PT Danantara. • Indonesia is the world’s largest palm oil exporter and a key nickel producer for EV batteries. • Follows earlier measures like the 2020 nickel ore export ban aimed at domestic value addition. • Markets reacted negatively amid fears of supply disruptions and excessive state control. • India heavily depends on Indonesian palm oil and coal imports. WHY IT MATTERS • Could affect global food, energy and EV supply chains. • Reflects broader trend of “resource nationalism” worldwide. • Important for India’s energy security and edible oil inflation.
