The judiciary is the guardian of the Constitution and the protector of your Fundamental Rights. For CDS & OTA, expect questions on the Supreme Court’s composition, jurisdiction, judicial review and the High Courts. India follows a single, integrated judicial system — unlike the United States — where the Supreme Court sits at the apex and all courts below it form one pyramid.
Why the Judiciary Matters in CDS Polity
In every CDS and OTA General Studies paper, Polity contributes a reliable cluster of questions, and the judiciary is among the most heavily tested areas. Questions are usually fact-based: number of judges, appointing authority, types of jurisdiction, and which article deals with what.
The judiciary performs three big functions in a democracy. It settles disputes between citizens, between citizens and the State, and between the Union and the States. It acts as the guardian of the Constitution, striking down any law that violates it. And it is the protector of Fundamental Rights through the power to issue writs.
India has a single integrated judiciary. The same hierarchy of courts enforces both Union and State laws. The USA, by contrast, has separate federal and state court systems — a favourite comparison in objective papers.
The Three-Tier Structure of Indian Courts
Picture the judiciary as a pyramid with three levels:
- Supreme Court — at the very top, located in New Delhi. Its decisions bind every court in the country.
- High Courts — one for each State (some are shared by two or more States/UTs). They are the highest court within a State.
- Subordinate (District & lower) courts — at the base, dealing with civil and criminal cases at the district level.
Because all these courts flow into one apex, an order passed by the Supreme Court is enforceable everywhere, and a judgement of one High Court can be cited (though not strictly binding) before another.
Integration means: one Supreme Court → High Courts → subordinate courts, enforcing a single system of laws. There is no separate set of “central” and “state” courts.
Supreme Court: Composition and Appointment
The Supreme Court of India (Articles 124 to 147) consists of the Chief Justice of India (CJI) and other judges. The original Constitution fixed the strength at 8, but Parliament can increase it by law; the sanctioned strength today is the CJI plus a number of other judges (Parliament has progressively raised this over the decades).
How judges are appointed
Judges of the Supreme Court are appointed by the President. In appointing the CJI, the President consults such judges as deemed necessary; for other judges, the CJI is always consulted. In practice, appointments now run through the Collegium system — a group of senior-most judges who recommend names.
Qualifications
- Must be a citizen of India.
- Has been a judge of a High Court for 5 years, OR an advocate of a High Court for 10 years, OR is, in the President’s opinion, a distinguished jurist.
Tenure and removal
A judge holds office until the age of 65 years. A judge can be removed only through impeachment by Parliament on grounds of proved misbehaviour or incapacity, passed by a special majority in both Houses.
Do not confuse retirement ages: Supreme Court judge retires at 65, High Court judge at 62. This single distinction has appeared in multiple PYQs.
Jurisdiction of the Supreme Court
The Supreme Court’s powers are grouped into several kinds of jurisdiction. Knowing these labels is half the battle in objective questions.
Original jurisdiction
Cases that go directly to the Supreme Court without any lower court first. This covers disputes between the Union and States, or between States — a federal umpire role. Enforcement of Fundamental Rights under Article 32 is also original jurisdiction.
Appellate jurisdiction
The Supreme Court is the highest court of appeal. Appeals come up in constitutional, civil and criminal matters from High Courts. Under Article 136, it may grant Special Leave to Appeal from any court or tribunal (except military tribunals).
Advisory jurisdiction
Under Article 143, the President may refer a question of law or public importance to the Supreme Court for its opinion. This opinion is advisory and not binding on the President.
Article 32 → right to move SC for writs (a Fundamental Right). Article 136 → Special Leave Petition. Article 143 → advisory opinion. Article 137 → review of its own judgements.
Judicial Review and the Court as Guardian
Judicial review is the power of the courts to examine the laws made by the legislature and the actions of the executive, and to declare them void if they violate the Constitution. It makes the judiciary the watchdog of constitutional supremacy.
If a law is found to be against the Constitution — for example, if it takes away a Fundamental Right — the court can strike it down. This is why the Supreme Court is called the guardian and final interpreter of the Constitution.
Basic Structure doctrine
Through landmark cases, the Supreme Court evolved the basic structure doctrine: Parliament can amend the Constitution but cannot destroy its essential framework — features such as supremacy of the Constitution, the rule of law, separation of powers, judicial review and federalism.
Judicial review is not the same as judicial activism. Review is the constitutional power to test laws; activism describes an assertive, expansive use of judicial power (often through PILs). Examiners deliberately mix these terms.
Writs: The Shield for Fundamental Rights
To protect Fundamental Rights, the Supreme Court (Article 32) and the High Courts (Article 226) can issue five writs. Learn them as a set — CDS loves matching questions.
- Habeas Corpus (“to have the body”) — orders that an unlawfully detained person be produced before the court.
- Mandamus (“we command”) — directs a public official or body to perform a legal duty it has failed to do.
- Prohibition — issued by a higher court to a lower court to stop exceeding its jurisdiction.
- Certiorari — a higher court quashes an order already passed by a lower court that lacked jurisdiction.
- Quo-Warranto (“by what authority”) — asks a person to show by what authority they hold a public office.
The High Court’s writ jurisdiction under Article 226 is wider than the Supreme Court’s under Article 32: a High Court can issue writs not only for Fundamental Rights but also for “any other purpose” (ordinary legal rights).
High Courts: Structure and Powers
The High Court is the highest court within a State (Articles 214 to 231). Each High Court has a Chief Justice and other judges whose number is fixed from time to time. A single High Court may serve more than one State or Union Territory.
Appointment and tenure
High Court judges are appointed by the President after consultation with the CJI and the Governor of the State (and, for other judges, the Chief Justice of that High Court). A High Court judge holds office until 62 years of age.
Qualifications
- Citizen of India.
- Held a judicial office in India for 10 years, OR has been an advocate of a High Court for 10 years.
Powers
A High Court hears appeals from district courts, exercises writ jurisdiction under Article 226, and has the power of superintendence (Article 227) over all courts and tribunals within its territory.
Note the qualification gap: there is no “distinguished jurist” route for High Court judges — that category exists only for the Supreme Court. Spotting these small differences wins marks.
Subordinate Courts and Judicial Independence
Below the High Court are the subordinate courts at the district level (Articles 233 to 237). On the civil side, the District Judge is the highest authority; on the criminal side, the Sessions Judge. The District Judge is appointed by the Governor in consultation with the High Court.
Why independence is protected
For courts to be fair umpires, they must be free from executive and legislative pressure. The Constitution secures judicial independence through:
- Security of tenure — judges cannot be removed except by a difficult impeachment process.
- Fixed salaries charged on the Consolidated Fund, not subject to a vote.
- Separation of judiciary from executive (a Directive Principle, Article 50).
- A ban on practising before the same court after retirement, and on discussing judges’ conduct in legislatures.
Independence of the judiciary = security of tenure + fixed service conditions + freedom from political control. This is repeatedly tested as a “which of the following” statement question.
Public Interest Litigation and Judicial Activism
Public Interest Litigation (PIL) allows any public-spirited citizen to approach the court on behalf of those who cannot do so themselves — the poor, the illiterate, or the voiceless. The court relaxed the strict rule of locus standi (the idea that only the affected person may sue) to widen access to justice.
PIL fuelled judicial activism — the judiciary taking a proactive role in protecting rights and directing the State on issues like environment, prisons, and bonded labour. Critics call its overreach “judicial overreach”, where courts step into the domain of the legislature or executive.
PIL widened access to justice by easing locus standi. Judicial activism is the assertive use of that access; judicial overreach is its excessive form.
Worked Example: Reading a Statement Question
CDS questions often test you with paired statements. Here is how to reason through one methodically.
Consider the statements and decide which are correct: (1) Supreme Court judges retire at 65. (2) High Court judges retire at 60. (3) Article 32 is itself a Fundamental Right.
The trap is statement 2. By fixing the retirement ages firmly (65 and 62), you avoid the most common error and answer in seconds.
Previous-Year Style Question
Q. The writ issued by a court to a public official directing the performance of a public duty that the official has failed to perform is called:
Answer: Mandamus. The word means “we command”. It is issued to a public authority or official to compel the performance of a legal/public duty. (Habeas Corpus relates to unlawful detention; Quo-Warranto questions the authority to hold an office; Certiorari quashes a lower court’s order.)
Whenever a question describes a writ by its function, translate the Latin name first. The literal meaning almost always points to the correct option.
Quick Revision
- India has a single integrated judiciary: Supreme Court → High Courts → subordinate courts.
- Supreme Court: Articles 124–147; judges appointed by the President; retire at 65.
- Jurisdictions: original (Art 32, federal disputes), appellate (Art 136 SLP), advisory (Art 143).
- Judicial review lets courts strike down unconstitutional laws; basic structure limits amendments.
- Five writs: Habeas Corpus, Mandamus, Prohibition, Certiorari, Quo-Warranto (Art 32 SC, Art 226 HC).
- High Court judges retire at 62; Art 226 writ power is wider than Art 32; Art 227 = superintendence.
- PIL eased locus standi; it powered judicial activism.
Frequently asked questions
What is the difference between Article 32 and Article 226?
Article 32 gives citizens the right to move the Supreme Court directly to enforce Fundamental Rights, and it is itself a Fundamental Right. Article 226 lets High Courts issue writs for Fundamental Rights and for any other legal right, making its scope wider.
At what age do Supreme Court and High Court judges retire?
A Supreme Court judge retires at 65 years of age, while a High Court judge retires at 62 years. This pair of numbers is a very common CDS objective question.
What is judicial review?
Judicial review is the power of the courts to examine laws and executive actions and declare them void if they violate the Constitution. It makes the judiciary the guardian and final interpreter of the Constitution.
What is the basic structure doctrine?
It is a principle evolved by the Supreme Court holding that Parliament can amend the Constitution but cannot alter its essential framework, such as the supremacy of the Constitution, rule of law, judicial review and federalism.
Why is independence of the judiciary important?
An independent judiciary can act as a fair umpire between citizens and the State without fear or favour. The Constitution secures it through security of tenure, fixed salaries charged on the Consolidated Fund, and separation of the judiciary from the executive.
What is the role of PIL in the Indian judiciary?
Public Interest Litigation lets any public-spirited person approach the court on behalf of those unable to do so. By relaxing the rule of locus standi, it widened access to justice and gave rise to judicial activism.
