The President of India has three options when a bill (other than Money Bill or Constitutional Amendment Bill) is presented for assent: (1) Give assent — bill becomes law; (2) Return the bill for reconsideration (veto/suspensive veto) — if Parliament passes it again (with or without amendment), the President MUST give assent; (3) Keep the bill pending indefinitely (Pocket Veto) — unlike the US where the President has 10 days to act, the Indian Constitution sets NO time limit for the President to give assent. Presidents have used this: President Giani Zail Singh kept the Postal Services Bill (1986) pending indefinitely; President Venkataraman kept the Bihar Termination of Pregnancy Act pending. This is India's unique "pocket veto" — the absence of a mandatory time limit.
*Why A is wrong:* Returning within 14 days is for governors under Article 200 — not the President.
*Why C is wrong:* No 30-day limit exists for the President.
*Why D is wrong:* President cannot attach conditions to assent.

Article 123 limitations on Presidential ordinance power: (1) Ordinances can only be issued when BOTH Houses of Parliament are NOT in session (or one house is not in session) — not during session; (2) Can only be issued on matters within Parliament's legislative competence (Union List, Concurrent List, matters under Articles 249-250); (3) Ordinance is void if it would be beyond Parliament's amending power (Basic Structure); (4) Lapses within 6 weeks of reassembly of Parliament unless both Houses pass a resolution approving it; (5) Can be withdrawn by the President anytime. The President CANNOT issue ordinances on subjects in the State List — those are for State Governors under Article 213 to issue ordinances on state subjects. Option C states an incorrect limitation — it's actually a prohibition, not a permitted power.
*Why A is wrong:* A is a valid/real limitation on ordinance power — correct limitation.
*Why B is wrong:* 6-week lapse is a valid limitation — correct limitation.
*Why D is wrong:* Void if beyond Parliament's competence — this is a correct limitation.

The evolution of judicial appointments through collegium: (1) First Judges Case (S.P. Gupta, 1982) — held that the executive has primacy in judicial appointments; CJI's recommendation is not binding; (2) Second Judges Case (SCAORA, 1993) — overruled First Judges Case; held that the CJI has primacy, and the collegium (CJI + 2 senior SC judges) must be consulted; collegium's recommendation is BINDING; (3) Third Judges Case (Presidential Reference, 1998) — expanded the collegium to CJI + 4 senior judges for SC appointments; 2 senior judges for HC appointments. The collegium system replaced executive primacy with judicial collegium primacy. NJAC (99th Amendment, 2014) was struck down in 2015.
*Why A, C, D are wrong:* These cases are significant but not related to judicial appointments/collegium system development.

During the Emergency (1975–77), the Presidential Order suspended enforcement of Articles 14, 19, 21, 22 under Article 359. In ADM Jabalpur v. Shivkant Shukla (1976), the Supreme Court's majority (4-1, with Justice H.R. Khanna dissenting) held that during Emergency, even the right to life (Article 21) is suspended and courts cannot issue habeas corpus against preventive detention. This was widely criticized as the Supreme Court's darkest moment. The 44th Amendment (1978) reversed this by inserting Article 20 and 21 cannot be suspended even during Emergency — making them inviolable. Justice H.R. Khanna's lone dissent is celebrated; his career was punished by being superseded for the CJI post by the Janata Government's predecessor.
*Why A is wrong:* Articles 14 and 19 could be and were suspended, but the question is about what could NOT be suspended under the 44th Amendment correction.
*Why C is wrong:* Religion articles (25-26) are not the Emergency-specific articles.
*Why D is wrong:* Article 32 enforcement can be suspended under Article 359 during Emergency.

Section 8 of the Representation of the People Act (RPA), 1951 disqualifies persons convicted for specific offenses with 2 or more years' imprisonment. The disqualification persists for 6 years from: the date of conviction (if not imprisoned), OR the date of release from prison (if imprisoned). The Supreme Court in Lily Thomas v. Union of India (2013) ruled that persons serving 2+ year sentences in criminal cases are disqualified from the date of conviction — they cannot remain as MPs/MLAs while in prison/pending appeal. Earlier, Section 8(4) allowed them to continue as long as appeal was pending — the SC struck down this protection. This judgment applies to sitting MPs/MLAs too (not just candidates).
*Why A is wrong:* The threshold is 2 years, not 6 months; and it must be specified offenses.
*Why C is wrong:* The RPA covers a wide range of offenses, not only election-related ones.
*Why D is wrong:* Mere arrest warrant doesn't disqualify — actual conviction with 2+ years sentence required.

Article 338 provides for the National Commission for Scheduled Castes (NCSC). The 89th Amendment (2003) bifurcated the earlier joint SC/ST Commission into: (1) National Commission for Scheduled Castes (Article 338); (2) National Commission for Scheduled Tribes (Article 338A). The NCSC's functions: investigate and monitor implementation of constitutional/legal safeguards for SCs; inquire into specific complaints; participate in planning for socioeconomic development of SCs; present annual reports to the President. The President nominates the NCSC chairperson, vice-chairperson, and 3 members. States with SCs over 25% of population also have State SC Commissions.
*Why A is wrong:* Article 330 provides for reservation of seats in Lok Sabha for SC/ST — not establishment of NCSC.
*Why C is wrong:* Article 339 deals with Central direction over administration of Scheduled Areas.
*Why D is wrong:* Article 350 deals with instructions in mother tongue — not NCSC.

Article 262 deals with adjudication of inter-state water disputes: (1) Parliament may by law provide for adjudication of any dispute relating to use, distribution, or control of waters of any inter-state river; (2) Parliament may exclude the jurisdiction of the Supreme Court and other courts from such disputes. Under the Inter-State River Water Disputes Act, 1956, the Central Government can set up a Water Disputes Tribunal. Tribunal awards are binding on all parties. Famous tribunals: Cauvery (Tamil Nadu-Karnataka), Krishna (AP-Maharashtra-Karnataka), Ravi-Beas (Punjab-Rajasthan-Haryana), Narmada (MP-Gujarat-Maharashtra-Rajasthan). Bihar's major inter-state river issues involve Ganga/Kosi/Gandak with neighboring states/Nepal.
*Why A is wrong:* Supreme Court's jurisdiction is specifically EXCLUDED — Parliament sets up Tribunals instead.
*Why C is wrong:* State legislation cannot resolve inter-state disputes.
*Why D is wrong:* President cannot unilaterally divide waters — Parliament must create the legislative framework.

The Doctrine of Eclipse was established in Bhikaji Narain Dhakras v. State of MP (1955). It applies to laws existing BEFORE the Constitution (1950). Such pre-constitutional laws are not absolutely void under Article 13(1) — they are merely "eclipsed" (dormant/unenforceable) to the extent they're inconsistent with Fundamental Rights. If the relevant FR is later amended to permit such laws, the eclipse is removed and the law becomes operative again. Example: A pre-1950 law restricting speech is eclipsed by Article 19 — but not void. If Article 19 is amended to allow such restriction, the old law revives. Contrast with Doctrine of Severability (post-constitutional laws that violate FRs are VOID to that extent, not merely eclipsed).
*Why A is wrong:* Pre-constitutional inconsistent laws are eclipsed (dormant), not automatically void.
*Why C is wrong:* Emergency laws are not subject to the Doctrine of Eclipse.
*Why D is wrong:* This describes the general principle of later law prevailing, not Doctrine of Eclipse.

Vishaka v. State of Rajasthan (1997) arose from the gang rape of Bhanwari Devi, a social worker in Rajasthan, while she tried to prevent a child marriage. The Supreme Court (Justice J.S. Verma bench) held: (1) Sexual harassment at the workplace violates Articles 14, 19, and 21; (2) In the absence of domestic legislation, the Court drew from CEDAW (UN Convention on Elimination of All Forms of Discrimination Against Women) and international norms; (3) Laid down the Vishaka Guidelines — defining sexual harassment, mandating complaints committees, awareness measures — treating them as binding law under Article 141 (SC pronouncements are law of the land). Parliament eventually enacted the POSH Act (Prevention, Protection and Redressal of Sexual Harassment at Workplace Act, 2013).
*Why A is wrong:* OBC reservation case was Indra Sawhney v. Union of India (1992) — the Mandal Commission case.
*Why C is wrong:* Section 377 was read down in Navtej Singh Johar v. Union of India (2018).
*Why D is wrong:* UCC remains unimplemented; SC has urged Parliament but not ordered it.

Under Article 245, Parliament can make laws for the whole or any part of India, and a State Legislature can make laws for the whole or any part of the state. However, state laws can have extra-territorial operation if there is a sufficient nexus. In State of Bombay v. RMDC (1957), the Supreme Court held that a state can tax a lottery ticket buyer outside the state if the ticket affects activities within the state. The GVK Industries v. Income Tax Officer (2011) further clarified that states can legislate for things/persons outside the state if the nexus is real and substantial — not illusory. This doctrine limits the geographical restriction, allowing states some extra-territorial legislative reach.
*Why A is wrong:* This describes the basic rule — the doctrine creates an EXCEPTION to mere territorial limitation.
*Why C is wrong:* Parliamentary legislation on state subjects during emergency is under Articles 250, 352, 353.
*Why D is wrong:* Article 3 deals with state reorganization/bifurcation — not Territorial Nexus.

Indra Sawhney v. Union of India (1992) — 9-judge bench decided: (1) 27% reservation for OBCs (Mandal Commission recommendation) is valid; (2) Total reservations should not ordinarily exceed 50% (including SC + ST + OBC = maximum 50%); exceptional circumstances can justify temporary crossing; (3) Reservation in PROMOTIONS for OBCs is NOT permitted under Article 16(4) — only at initial appointments; (4) Creamy layer (economically advanced OBCs) must be excluded from OBC reservation; (5) "Backward Classes" should be identified on social backwardness, not economic status alone; (6) Reservation is a constitutional right, not a fundamental right; (7) Permanent Backward Classes Commission recommended. Article 16(4A) was later added to allow reservation in promotion for SC/ST specifically.
*Why A is wrong:* The cap is 50% with narrow exceptions — the court upheld this cap.
*Why C is wrong:* Court upheld reservations — just put limits on them.
*Why D is wrong:* Reservation policy is subject to judicial review as per Indra Sawhney itself.

S.R. Bommai v. Union of India (1994) — 9-judge bench — was a landmark case that significantly restricted the misuse of Article 356 (President's Rule). Key holdings: (1) President's satisfaction under Article 356 is subject to JUDICIAL REVIEW; (2) A government commanding majority in the Assembly cannot be dismissed merely on the basis of the Governor's report — the majority must be tested on the floor of the House; (3) State Legislative Assembly must NOT be dissolved until Parliamentary approval of the proclamation; (4) Court can restore the dismissed government if proclamation is found unconstitutional; (5) Secularism is a basic structure element — if a state government promotes communalism, it can justify Article 356 proclamation. This case significantly reduced misuse of Article 356 for political purposes.
*Why A is wrong:* State boundary changes are under Article 3 with State Legislature's views (though not consent).
*Why C is wrong:* Bommai actually RESTRICTED Governor's discretion, not confirmed absolute discretion.
*Why D is wrong:* President's Rule lasts 6 months initially but can be extended with Parliament's approval; it doesn't auto-terminate.

The Doctrine of Colourable Legislation states: "What cannot be done directly cannot be done indirectly." If a legislature lacks the power to enact a law directly on a subject, it cannot achieve the same result by a colorable (indirect) method. For example, if a state enacts a law purportedly on "health" (State List) but actually regulates banking (Union List), the law is colorably legislated — its true nature is banking regulation. Courts apply the "pith and substance" test to find the true nature of legislation: if the dominant aspect belongs to a subject beyond the legislature's competence, the law is void as colourable legislation. Applied frequently in distribution of legislative powers disputes between Centre and states.
*Why A is wrong:* Has nothing to do with drafting clarity or color-coding.
*Why C is wrong:* Colourable refers to "appearing" as legitimate — not corrupt procedures.
*Why D is wrong:* Judicial ambiguity is "judicial hedging" — not colourable legislation.

The 99th Constitutional Amendment (2014) replaced the collegium system with the National Judicial Appointments Commission (NJAC) — consisting of: CJI (Chairperson), 2 senior-most SC judges, Union Law Minister, and 2 eminent persons. The Supreme Court in Supreme Court Advocates-on-Record Association v. Union of India (2015) — by a 4:1 majority (Justice J. Chelameswar dissented) — struck down the NJAC as unconstitutional because: (1) It violated the "independence of the judiciary" — a basic structure element; (2) The Law Minister's membership gave the executive a role in judicial appointments — threatening independence; (3) The "eminent persons" clause could allow political influence; (4) Any two members (including Law Minister + one eminent person) could veto any appointment — effectively giving executive a veto. The collegium system was restored.
*Why A is wrong:* Anti-Defection Law (10th Schedule) has no connection to NJAC.
*Why C is wrong:* Constitutional Amendment ratification by states is required only for certain federal provisions; this is not why NJAC was struck down.
*Why D is wrong:* Law Minister is the AG equivalent — it's not unconstitutional for them to sit on a commission; the issue was the veto power this gave the executive.

Bihar provides 50% reservation for women in all three tiers of Panchayati Raj institutions (Gram Panchayat, Panchayat Samiti, Zila Parishad) — including for positions of Mukhiya (Sarpanch), Pramukh, and Adhyaksha. The Constitution mandates minimum 1/3 (33%) reservation for women in Panchayats. Bihar went beyond this by providing 50% reservation. The Bihar Panchayati Raj Act, 2006 implements this. Bihar also provides reservation for SC/ST (proportional to population), Extremely Backward Classes (EBC — Bihar-specific category), and OBCs in PRIs. Other states with 50% women's reservation in PRIs: Rajasthan, Uttarakhand, Andhra Pradesh, Telangana, Himachal Pradesh, Chhattisgarh, and many others.
*Why A is wrong:* Bihar provides 50% — exceeding the 33% constitutional minimum.
*Why C is wrong:* 20% is below the constitutional requirement.
*Why D is wrong:* Bihar explicitly provides 50% women's reservation beyond the constitutional mandate.
