Indian Legal System Explained: Courts, Codes, and Legal Aid

The Indian legal system is a constitutional framework built on English common law foundations, in which a written Constitution sits above every legislature, executive, and court, a three-tier judiciary runs from district courts up through the High Courts to the Supreme Court, and criminal matters are now governed by three new codes that replaced colonial-era statutes on July 1, 2024. Statutes, judicial precedent, and recognized custom all operate as sources of binding law, and specialized tribunals, consumer commissions, and alternative dispute resolution forums handle large volumes of cases outside the regular courts.

The Constitution Sits at the Top

The Constitution of India is the supreme legal document in the country. The Constituent Assembly adopted it on November 26, 1949, and it came into force on January 26, 1950.1India.gov.in. Constitution of India Any legislation or executive action that conflicts with it can be struck down by the courts.

The Preamble declares India a Sovereign Socialist Secular Democratic Republic and commits the state to justice, liberty, equality, and fraternity.2Constitution of India. Preamble – Constitution of India Authority is divided across three branches. The legislature makes laws. The executive implements them. The judiciary interprets them and resolves disputes.

Fundamental Rights You Can Enforce

Part III of the Constitution guarantees rights that individuals can enforce directly through the courts if the state infringes them. They fall into six categories:3Ministry of External Affairs, Government of India. Part III Fundamental Rights

  • Right to Equality (Articles 14–18), prohibiting discrimination on grounds of religion, race, caste, sex, or place of birth, and abolishing untouchability and titles.
  • Right to Freedom (Articles 19–22), covering speech, assembly, movement, and the right to practice any profession, with protections against arbitrary arrest.
  • Right against Exploitation (Articles 23–24), banning human trafficking, forced labor, and the employment of children in hazardous work.
  • Right to Freedom of Religion (Articles 25–28).
  • Cultural and Educational Rights (Articles 29–30), protecting minorities and their educational institutions.
  • Right to Constitutional Remedies (Article 32), allowing any person to approach the Supreme Court directly to enforce any fundamental right.

Article 21, the right to life and personal liberty, carries weight far beyond its literal text. Indian courts have read into it the right to a clean environment, privacy, livelihood, and dignified treatment.4Constitution of India. Article 21 Protection of Life and Personal Liberty The Constitution also contains Directive Principles of State Policy, which guide the government toward a just social order but are not enforceable in court. Article 39A, for instance, directs the state to provide free legal aid so no one is denied justice because of economic hardship.5Constitution of India. Article 39A – Equal Justice and Free Legal Aid

The Limit on Amending the Constitution

Parliament can amend the Constitution, but not without limit. In 1973, the Supreme Court ruled in Kesavananda Bharati v. State of Kerala that Parliament cannot use its amendment power to destroy or alter the Constitution’s basic structure. That doctrine protects features like democracy, secularism, federalism, the rule of law, separation of powers, and the independence of the judiciary from any amendment.6Supreme Court of India. The Basic Structure Judgment The decision was a 7–6 split, and every subsequent attempt to concentrate power in the legislature has been measured against it. The Supreme Court has struck down amendments that crossed the line, including the 2015 attempt to replace the current judicial appointments system.

How the Courts Are Structured

India’s courts follow a three-tier structure. Cases begin at the district level, move up to the High Courts, and can ultimately reach the Supreme Court. Pending cases across all three tiers exceed 55 million, making the backlog one of the system’s most persistent problems.

Supreme Court of India

The Supreme Court sits at the apex, established under Article 124 of the Constitution. It consists of the Chief Justice of India and up to 33 other judges.7Constitution of India. Article 124 – Establishment and Constitution of Supreme Court It exercises original jurisdiction over disputes between the central government and state governments, appellate jurisdiction over lower court decisions, and advisory jurisdiction when the President refers a question of law.

Under Article 32, any person whose fundamental rights are violated can petition the Supreme Court directly. The Court can issue writs of habeas corpus, mandamus, prohibition, quo warranto, and certiorari to enforce those rights.8Indian Kanoon. Article 32 in Constitution of India Under Article 141, any law the Supreme Court declares is binding on every other court in the country.9Constitution of India. Article 141 – Law Declared by Supreme Court to Be Binding on All Courts

High Courts

Below the Supreme Court are High Courts, one for each state or group of states, established under Article 214.10Constitution of India. Article 214 – High Courts for States Each is the highest judicial authority in its territory. Under Article 226, a High Court can issue writs not only to protect fundamental rights but “for any other purpose,” giving it broader writ jurisdiction than the Supreme Court itself.11Constitution of India. Article 226 – Power of High Courts to Issue Certain Writs Article 227 grants every High Court supervisory power over all courts and tribunals in its territory, including authority to call for records, prescribe procedural rules, and set fee schedules.12Indian Kanoon. Article 227 in Constitution of India That combination makes High Courts the primary venue for challenging government action at the state level.

District and Subordinate Courts

The third tier handles the vast majority of initial trials. District courts are split into civil and criminal wings, presided over by District Judges for civil matters and Sessions Judges for serious criminal cases. Magistrate courts handle lesser criminal offenses. These are the courts that process property disputes, contract claims, assault cases, and theft prosecutions, and every decision at this level can be appealed upward.

Who Appoints the Judges

Supreme Court and High Court judges are not elected and are not selected purely by the executive. India uses the Collegium system: a panel of sitting Supreme Court judges recommends appointments. For Supreme Court positions, the Collegium consists of the Chief Justice of India and the four senior-most judges. The system evolved from three Supreme Court decisions between 1981 and 1998, not from any explicit constitutional provision. In 2015, the Supreme Court struck down the National Judicial Appointments Commission Act, which had tried to give the legislature and executive a formal role in selecting judges, ruling that it violated judicial independence under the basic structure doctrine. The Collegium remains contested: supporters say it shields courts from political pressure, while critics argue it lacks transparency and amounts to judges selecting their own successors.

Where the Law Itself Comes From

Indian law draws from several overlapping sources. Statutes are the most direct. Parliament legislates for the country, state legislatures for regional matters. The Constitution divides legislative subjects into three lists: the Union List (defense, banking, foreign affairs), the State List (police, land, public health), and the Concurrent List (criminal law, education, marriage), where both levels can legislate, with central law prevailing in a conflict. Delegated legislation, such as rules and notifications issued by administrative bodies, fills in operational details that Parliament does not specify.

Precedent is a binding source of law, not just persuasive guidance. Article 141 makes Supreme Court declarations of law binding on all courts throughout India.13Indian Kanoon. Article 141 in Constitution of India High Court decisions bind subordinate courts within their territorial jurisdiction. The Supreme Court itself is not bound by its own previous decisions and can overrule earlier judgments.

Customs that are long-established, certain in content, and not opposed to public policy can also be recognized as law. This matters most in family and local land disputes. Courts scrutinize customary claims carefully, and any custom that contradicts a fundamental right or an existing statute will lose.

Alongside the standard sources, the Right to Information Act of 2005 gave citizens a statutory right to request information from any public authority. Agencies must respond within 30 days, and within 48 hours if the information involves a threat to someone’s life or liberty.

The New Criminal Codes

On July 1, 2024, three new codes replaced the colonial-era criminal statutes that had governed India for over 150 years:14Ministry of Home Affairs, Government of India. Provisions Under BNS

  • The Bharatiya Nyaya Sanhita (BNS), 2023, replaced the Indian Penal Code of 1860. It defines criminal offenses and penalties, introduces new categories like mob lynching under Section 103(2), and restructures the classification of existing crimes.15Sansad.in. Provisions Under BNS
  • The Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, replaced the Code of Criminal Procedure of 1973. It mandates forensic evidence collection for offenses carrying seven or more years of imprisonment, allows video conferencing for court proceedings, and sets fixed timelines: 14 days for preliminary inquiries, 14 days for providing case documents to the accused and victims, and 7 days for medical reports in sexual assault cases.
  • The Bharatiya Sakshya Adhiniyam (BSA), 2023, replaced the Indian Evidence Act of 1872. It treats electronic records as primary evidence rather than secondary evidence, permits witnesses to testify electronically, and expands the definition of electronic records to cover emails, server logs, smartphone data, and location evidence.

As of early 2026, the central government is still providing training and technical assistance to states and union territories for full implementation. The transition is significant because nearly every police officer, prosecutor, and judge in the country must learn a new statutory framework, and older case law referencing the IPC and CrPC must be mapped to the corresponding BNS and BNSS provisions. Anyone involved in an ongoing criminal case should confirm which code applies to their proceedings.

Civil, Criminal, and Personal Law

Civil Disputes

Civil law governs disputes between individuals or organizations, typically involving contracts, property, torts, and family matters. The goal is compensation or specific performance rather than punishment. The Code of Civil Procedure of 1908 remains in force and sets out the procedural steps for filing suits, presenting evidence, and executing court decrees.16India Code. The Code of Civil Procedure, 1908 The Commercial Courts Act of 2015 created specialized courts for business disputes above a minimum threshold of ₹3 lakhs, with a mandatory six-month timeline for resolution after the initial case management hearing and a pre-institution negotiation requirement before filing.

Criminal Matters

Criminal cases are brought by the state, carry penalties ranging from fines to life imprisonment, and in the rarest cases, the death penalty. The BNS defines the offenses, the BNSS governs procedure from investigation through trial, and the prosecution must establish guilt beyond a reasonable doubt. Accused persons have constitutional protections against self-incrimination under Article 20 and a right to be informed of the grounds of arrest under Article 22.3Ministry of External Affairs, Government of India. Part III Fundamental Rights

Personal Laws

Family matters are governed by separate personal laws tied to religious identity. Marriage, divorce, inheritance, and guardianship each follow distinct codes for Hindus, Muslims, Christians, and Parsis. The Hindu Marriage Act of 1955 provides one framework. The Muslim Personal Law (Shariat) Application Act of 1937 directs that Muslims be governed by Islamic personal law on matters like marriage, divorce, maintenance, and succession.17India Code. Muslim Personal Law (Shariat) Application Act, 1937 Courts can strike down personal law provisions that violate fundamental rights, and calls for a Uniform Civil Code remain an active political and legal debate.

Consumer Complaints

The Consumer Protection Act of 2019 created a three-tier system of commissions for complaints against sellers and service providers. Under the 2021 rules, district commissions handle claims where the value does not exceed ₹50 lakh, state commissions hear complaints above ₹50 lakh but not exceeding ₹2 crore, and the National Commission handles complaints above ₹2 crore.18Press Information Bureau, Government of India. The Revised Pecuniary Jurisdiction for Entertaining Consumer Complaints These commissions are designed to be faster and less formal than regular courts, and consumers can file complaints without a lawyer. Decisions at each level can be appealed to the next tier.

Specialized Tribunals

Some disputes are routed to tribunals with subject-matter expertise rather than generalist courts.

The National Green Tribunal, established in 2010, has jurisdiction over all civil cases involving a substantial environmental question, including pollution, forest conservation, and hazardous waste disposal. It can order compensation for victims of environmental damage and direct restoration of damaged ecosystems.19National Green Tribunal. About Us – Jurisdiction, Powers, and Proceedings It is not bound by the Code of Civil Procedure or the rules of evidence, follows principles of natural justice, and aims to dispose of cases within six months. Complaints must be filed within six months of the environmental harm, though the tribunal can extend this by another 60 days for good cause. Appeals go directly to the Supreme Court.

The National Company Law Tribunal was constituted under the Companies Act of 2013 and began operating in June 2016. It handles corporate insolvency and bankruptcy proceedings, mergers and amalgamations, shareholder oppression claims, and company winding-up petitions.20NCLT. National Company Law Tribunal It has benches across major cities, with appeals going to the National Company Law Appellate Tribunal and from there to the Supreme Court. The Insolvency and Bankruptcy Code of 2016 made it the central forum for resolving corporate insolvency.

Settling Disputes Outside Court

Given the scale of the backlog, alternative dispute resolution has become increasingly important.

Lok Adalats

Lok Adalats, or “People’s Courts,” operate under the Legal Services Authorities Act of 1987 and settle disputes through compromise rather than adversarial proceedings. They handle pending court cases and pre-litigation disputes across property disagreements, motor accident claims, labor disputes, cheque-bounce cases, and consumer complaints. Their jurisdiction covers compoundable criminal offenses but excludes serious crimes like murder or sexual assault.21India Code. The Legal Services Authorities Act, 1987 Every Lok Adalat award is deemed a decree of a civil court, is final and binding on the parties, and cannot be appealed. Court fees paid in referred cases are refunded. National Lok Adalat events regularly settle millions of cases in a single sitting.

Arbitration

The Arbitration and Conciliation Act of 1996 governs both domestic and international commercial arbitration. Parties choose their arbitrators (an odd number; a sole arbitrator is the default if they cannot agree), and the tribunal must issue its award within 12 months of completing pleadings in domestic cases.22India Code. The Arbitration and Conciliation Act, 1996 An arbitral award is final and binding, and once the challenge window closes, it is enforced like a civil court decree. Courts can set aside an award only on narrow grounds such as fraud, corruption, or a violation of public policy. A draft amendment bill circulated in 2024 proposes shifting more powers from courts to arbitral institutions and tightening timelines, but those changes have not been enacted.

Mediation

The Mediation Act of 2023 provides a formal legal framework for mediation for the first time. Pre-litigation mediation is voluntary, but courts and tribunals can refer parties to mediation at any stage of a pending case. A settlement agreement reached through mediation is enforceable like a court decree. A party can challenge a mediated settlement only on grounds of fraud, corruption, or impersonation, and must file within 90 days of receiving the agreement, with a possible 90-day extension for good cause.

Public Interest Litigation

One distinctive feature of the Indian system is Public Interest Litigation. In most legal systems, only the directly injured party can bring a claim. Indian courts allow any citizen acting in good faith to petition on behalf of people who cannot approach the courts themselves due to poverty, disability, or social marginalization. PILs are filed under Article 32 in the Supreme Court or Article 226 in a High Court.8Indian Kanoon. Article 32 in Constitution of India The court can also take up matters on its own initiative.

PILs have reshaped Indian law on environmental protection, prisoner rights, child labor, and government accountability. In M.C. Mehta v. Union of India (1987), the Supreme Court ordered the closure of tanneries polluting the Ganges. In Rural Litigation and Entitlement Kendra v. State of Uttar Pradesh (1985), it halted illegal limestone mining in the Mussoorie hills. These cases established that courts could impose affirmative obligations on the government to protect the environment. The threshold for filing is low, but courts screen out frivolous petitions, and the person filing must show that the petition genuinely serves the public interest.

Free Legal Aid and Who Qualifies

Free legal aid is both a constitutional directive and a statutory entitlement. Article 39A directs the state to ensure the legal system promotes justice on a basis of equal opportunity, and the Legal Services Authorities Act of 1987 puts that directive into practice.5Constitution of India. Article 39A – Equal Justice and Free Legal Aid Under Section 12 of that Act, these categories are entitled to free legal services:23India Code. Legal Services Authorities Act, 1987

  • Members of Scheduled Castes or Scheduled Tribes
  • Victims of human trafficking or forced labor
  • Women and children
  • Persons with disabilities
  • Victims of mass disasters, ethnic violence, caste atrocity, or natural calamities
  • Industrial workers
  • Persons in custody, including in protective homes or psychiatric institutions
  • Persons below a prescribed annual income threshold, set by the state government for cases before courts other than the Supreme Court, and by the central government for Supreme Court cases

The National Legal Services Authority at the apex, State Legal Services Authorities, and District Legal Services Authorities administer the scheme. They assign lawyers, organize Lok Adalats, and run legal literacy programs. The entitlement is not automatic: the authority must be satisfied that the applicant has a genuine case to prosecute or defend.
