The Chief Minister of Delhi is appointed by the __________.

The correct answer is C, Exclusive Original. Under Article 131, disputes between the Government of India and one or more States, or between States, can be heard only by the Supreme Court and by no other court. Such a case starts directly in the Supreme Court, which is why this is called original jurisdiction, and because no High Court can hear it, it is exclusive. The dispute must involve a legal right, not just a political quarrel. Option A is wrong because advisory jurisdiction under Article 143 is the President seeking the Court's opinion on a question of law or fact. Option B is wrong because appellate jurisdiction, under Articles 132 to 134, covers appeals against the judgments of High Courts. Option D is wrong because writ jurisdiction under Article 32 protects Fundamental Rights, and the High Courts share that power under Article 226. Exam tip: Article 131 original, Articles 132–134 appellate, Article 143 advisory, Article 32 writs.

The correct answer is D, Cooperative Societies. The 97th Constitutional Amendment Act, 2011 added Article 43B, a new Directive Principle asking the State to promote the voluntary formation, autonomous functioning, democratic control and professional management of cooperative societies. The same amendment made forming cooperative societies a Fundamental Right by adding these words to Article 19(1)(c), next to associations and unions. It came into force in February 2012. Option A is wrong because maternity relief was already part of the original Directive Principles in Article 42, which speaks of just and humane conditions of work. Option B is wrong because child labour is dealt with by Article 24, a Fundamental Right, and by Article 39; it was not the subject of the 97th Amendment. Option C is wrong because protection of the environment, Article 48A, was added much earlier by the 42nd Amendment of 1976. Exam tip: the 97th Amendment of 2011 put cooperatives in Article 19(1)(c) and Article 43B.

The correct answer is D, Certiorari. Certiorari means 'to be certified' or 'to be informed'. By this writ a higher court orders a lower court or tribunal to send up a case pending before it, or quashes an order it has already passed, when there is lack of jurisdiction, excess of jurisdiction or an error of law. The Supreme Court issues writs under Article 32 and the High Courts under Article 226. Prohibition and certiorari look alike, so note the timing: prohibition stops a case while it is still going on, while certiorari can also cancel a decision already made. Option A is wrong because prohibition only forbids a lower court from going beyond its jurisdiction; it does not transfer the case. Option B is wrong because mandamus, 'we command', orders a public official or body to do a duty it has failed to do. Option C is wrong because quo warranto, 'by what authority', asks a person to show his right to hold a public office. Exam tip: Certiorari = send up or quash; Prohibition = stop; Mandamus = do your duty.

The correct answer is B, Article 239. Article 239 says every Union Territory is administered by the President, acting through an administrator appointed by him with such designation as he thinks fit. That is why some Union Territories, such as Delhi, Ladakh and the Andaman and Nicobar Islands, have a Lieutenant Governor, while others have an Administrator. Article 239 opens Part VIII of the Constitution, which deals with Union Territories. Articles 239A and 239AA, added later, give legislatures to Puducherry and Delhi. Option A is wrong because Article 235 gives the High Court control over subordinate courts. Option C is wrong because Article 233 deals with the appointment of district judges by the Governor in consultation with the High Court. Option D is wrong because Article 234 deals with recruiting persons other than district judges to the judicial service of a state. Exam tip: Part VIII covers Union Territories in Articles 239 to 241, and Article 239AA is the special article for Delhi.

The correct answer is A, A-I, B-III, C-IV, D-II. The Comptroller and Auditor General (CAG) is covered by a neat run of four articles in Part V of the Constitution. Article 148 creates the office: the President appoints the CAG by warrant under his hand and seal, and the CAG can be removed only in the manner of a Supreme Court judge. Article 149 deals with the duties and powers, which Parliament has spelt out in the CAG (Duties, Powers and Conditions of Service) Act, 1971. Article 150 says the accounts of the Union and the states are kept in the form the President prescribes on the CAG's advice. Article 151 sends the CAG's audit reports on Union accounts to the President, who lays them before Parliament, while reports on a state go to the Governor. Option B is wrong because it puts appointment under Article 151. Option C is wrong because it places appointment under Article 149 and duties under Article 148. Option D is wrong because it swaps appointment and audit reports. Exam tip: 148 appointment, 149 powers, 150 form of accounts, 151 reports.
