Flag of India

India is the world’s most populous democracy, governed by the longest (in word count) constitution in the world. The Constitution of India came into effect in 1950 and forms the backbone of India’s constitutional supremacy system. India’s constitution is quasi-federal, with features of both federal and unitary constitutions. Its legal system has elements of civil law, common law, customary and religious law, and equitable law.

International sources of law, such as treaties or signed conventions, can be enforced in India if they have been ratified and incorporated into Indian law. In certain cases, customary principles of international law can be applied and enforced even without formal ratification if the law in question is not inconsistent with Indian law. For example, in a recent decision, the Supreme Court declared the precautionary principle, a cornerstone of international environmental law, to be customary international law and so incorporated into Indian law. When an international law conflicts with domestic law, the latter prevails.


Judicial System

The Indian judicial system is a single integrated system. The constitution divides the judiciary into two parts: the superior judiciary (consisting of the Supreme Court and the High Courts) and the subordinate judiciary (the lower courts, which are under the control of the High Courts).

  • The Supreme Court of India is India’s highest court and it sits in New Delhi.
  • There are 25 High Courts in India. Each of India’s twenty-eight states has one high court, although some high courts have jurisdiction over multiple states and territories.
  • States are divided into districts, each of which has its own District Court. With few exceptions, the district court has original jurisdiction for civil and criminal cases. When handling criminal matters, judges serve as “sessions judges” in “sessions courts.”
  • Quasi-judicial tribunals and commissions are independent of the judicial and executive branches. These were created by legislation to lessen the burden on the court system and reduce civil case delays. Quasi-judicial tribunals include:
    • The Central Administrative Tribunal, which handles disputes relating to public and civil servants
    • The National and State Human Rights Commissions, for the protection of human rights
    • The Competition Commission of India, which promotes and protects market competition
  • There are also specialized courts, including:
    • Family courts, which specialize in cases involving marriage, inheritance, and guardianship of minors
    • The Special Court of Central Bureau of Investigation, which handles cases involving corruption and bribery
    • Specific High Courts and District Courts, which have a docket entirely of commercial cases of specific value, including arbitration cases.

Judicial Tenure

Justices of the Supreme Court and High Courts have life tenure and cannot be removed from office except for misconduct or incapacity. However, there is a mandatory retirement age: 65 years of age for supreme court justices and 62 years of age for high court justices. Over the years, there have been calls to increase the retirement age.


The Supreme Court of India

Supreme Court judgments are binding on all courts, judicial authorities, and tribunals. The Supreme Court has the power of judicial review—that is, the power to declare unconstitutional acts of the legislature and executive.

The Supreme Court makes regular use of its power to appoint commissions of inquiry. These commissions investigate and provide further evidence in a case. This helps ensure the record is complete, without burdening the parties with the need to produce this evidence themselves. These commissions usually include lawyers, academics, and social workers, who investigate the allegations raised by the petitioner, do the fact-finding, and report back to the Court. These reports are treated as prima facie evidence.


The Suo Moto Petition

In suo moto cases, and other cases where the Supreme Court determines there is a significant power imbalance between the parties, the Supreme Court has innovated new procedures, including:

Relaxing standing doctrines. Rather than requiring a petitioner have suffered actual injury to have standing to sue, the Indian Supreme Court has permitted NGOs, social action groups, and individuals acting on behalf of others to sue to defend fundamental constitutional rights. Some of these suits result in the Court’s suo moto cognizance of the same case.

Acknowledging the imbalance of power between parties in the adversarial system. In these cases, the Court will be more proactive in ascertaining certain facts, or will shift the rebuttable presumptions, in an effort to create a fairer process between the two parties.

Innovating remedies. The Supreme Court has created a new range of remedies that are proactive and reactive, seeking to ameliorate constitutional, civil, and criminal wrongs all at once, saving the petitioner from having to return to court on multiple occasions to receive full redress.

Specifically retaining jurisdiction over the matter, and monitoring compliance with Court orders. Retaining jurisdiction permits a court to continue to issue orders and directives until final judgment is appropriate. The Court can also more easily monitor compliance and re-direct the commission’s inquiry as necessary.

In 2020, the Court had ten suo moto cases, the most of any year. In June 2021, the Court had eighteen pending suo moto cases, some of which were “continuing mandamus” cases, in which the Court retained jurisdiction to continue to issue orders as necessary, without having to open a new case.


Some notable examples of cases the Supreme Court has considered suo moto include:

An NGO dedicated to workers’ rights sent a letter to the Supreme Court alleging intolerable working conditions in certain stone quarries. Citing its suo moto power under Article 32 of the constitution, the Supreme Court took up this case and appointed a well-known professor of sociology to investigate the conditions of the stone quarry workers. On the basis of this report, the Supreme Court issued further orders to protect the workers’ fundamental rights.

In 2012, Parliament enacted the Protection of Children from Sexual Offenses Act (POCSO), legislation creating new procedures for reporting cases and specialized courts. The law requires cases to be disposed within a year of the offense being reported. The early numbers were not encouraging, and the Supreme Court registered a suo moto petition. In July 2019, the Court appointed a senior counsel to collect information about pending POCSO cases and report on their progress.

In 2015, a video of a gang rape circulated on social media in India. An NGO wrote to the Supreme Court, drawing its attention to the proliferation of such videos and and their viral circulation on social media. Based on the letter, the Court lodged a suo moto petition. The Court created a committee to advise the court on “the feasibility of ensuring that videos depicting rape, gang rape and child pornography are not available for circulation.” The committee was tasked with reporting on available technology solutions, for example auto-blocking software and filtering.

The Supreme Court has also made increasing use of the suo moto power to cope with the COVID-19 pandemic. In one case, the Court ordered the government to draft a national policy for the distribution of supplies, including oxygen, essential drugs, and vaccines. It directed the government to distribute supplies and essential services in an “even handed manner according to the advice of health authority which undoubtedly take into account relevant factors like severity, susceptibility, the number of people affected and the local availability of resources.” In another case, the Supreme Court questioned whether the government had an adequate plan to vaccinate people living in rural areas of the country.
