Prelims Strategy

For Prelims, a strong grasp of factual details related to the CBI is essential. Focus on the foundational legal provisions: the Delhi Special Police Establishment (DSPE) Act, 1946, particularly Sections 2, 3, and 6 (state consent).

Memorize the composition of the high-powered committee for the CBI Director's appointment (PM, CJI/SC Judge, LoP) and the tenure provisions (fixed two years, extendable up to five). Understand the specific superintendence roles of the Central Vigilance Commission (CVC) for corruption cases and the Lokpal for referred cases.

Be familiar with landmark judgments like Vineet Narain (fixed tenure, CVC status, 'Single Directive') and the 'caged parrot' remark from the Coal Allocation Scam. Pay attention to recent current affairs regarding CBI, such as new Director appointments, states withdrawing general consent, and high-profile cases, as these often form the basis of Prelims questions.

Differentiate CBI's mandate and jurisdiction from other agencies like NIA and ED. Use mnemonics like 'CBI-SPACE' to quickly recall key aspects.
