Public Interest Litigation (PIL) in India: A Beacon of Hope for Justice

Oct. 27, 2023   •   Abhinav Raizada


In a democratic society, the pursuit of justice often requires the active participation of citizens in ensuring that the state acts responsibly and in the public's best interests. Public Interest Litigation (PIL) has emerged as a powerful tool for achieving this objective, especially in the context of India. PIL is a judicial mechanism that allows individuals or organizations to file lawsuits on behalf of the public to address various issues that affect society. In this blog, we will explore the concept of PIL, its evolution in India, the subjects it can address, the process of filing PILs, the role of the Locus Standi rule, its importance, criticisms, instances of abuse, and landmark cases.

Concept of PIL

Public Interest Litigation, also known as "Social Interest Litigation" or "Socio-Legal Interest Litigation," is a legal remedy that focuses on the protection and promotion of the rights and interests of the general public. Unlike traditional litigation, where a party directly affected initiates a lawsuit, PIL allows any citizen or group, regardless of their personal interest, to initiate legal action on behalf of the larger public good.

Evolution of PIL in India

The rise and evolution of Public Interest Litigation (PIL) in India is a remarkable journey that has transformed the Indian legal landscape and played a pivotal role in addressing social injustices, human rights violations, and environmental concerns. The evolution of PIL can be understood through various phases and key developments:

Genesis of PIL: The genesis of PIL in India can be traced back to the early 1980s. It was a response to the prevailing social injustices, human rights violations, and environmental degradation in the country. During this period, the traditional mechanisms of seeking justice were often inaccessible, slow, and cumbersome, leaving the marginalized and vulnerable sections of society without effective remedies.

Role of Contemporary Judges: One of the driving forces behind the evolution of PIL in India was Justice P.N. Bhagwati, who served as the Chief Justice of India from 1985 to 1986. His tenure witnessed a remarkable transformation in the judiciary's approach to public interest cases. Justice Bhagwati recognized the need for a more accessible and responsive legal system that could address the urgent concerns of the public.[1]

Landmark Case of Hussainara Khatoon: The landmark case of Hussainara Khatoon v. Home Secretary, State of Bihar (1979)[2] is often cited as one of the earliest instances of PIL in India. In this case, undertrial prisoners languishing in jails for long periods without trial were granted release. This case highlighted the grave issue of prison overcrowding and prolonged incarceration without due process, setting a precedent for addressing systemic issues through PIL.

Expansion of Locus Standi: A significant evolution in PIL was the expansion of the "Locus Standi" rule. Traditionally, Indian courts required that a petitioner must have a direct and personal interest in a case to have the 'standing or locus' to file a lawsuit. However, in PIL, the courts recognized that violations of public rights and interests affect society as a whole. This recognition led to a relaxation of the locus standi rule, allowing any concerned citizen or organization to initiate legal action on behalf of the public good.

PIL as a Tool for Social Justice: PIL soon emerged as a powerful tool for social justice. It enabled citizens and advocacy groups to approach the judiciary directly, presenting issues of public interest. This shift in approach fostered a sense of accountability within government institutions and played a crucial role in curbing excesses and maladministration.

Expanding Horizons: PIL in India has progressively expanded its horizons. It began with cases related to issues such as bonded labor, custodial torture, and environmental pollution. Over time, it has encompassed a wide range of subjects, including environmental protection, healthcare, education, women's rights, human rights, corruption, and administrative transparency.

Supreme Court Guidelines: The Supreme Court of India has issued guidelines on the filing and handling of PILs to ensure their effective use while preventing abuse. These guidelines help the courts in distinguishing between cases that genuinely serve the public interest and those filed for personal or extraneous reasons.

Legacy and Influence: The legacy of PIL in India is profound. It has made the government more accountable, protected the environment, combated corruption, and advanced the cause of gender equality. Many landmark judgments and guidelines have emanated from PIL cases, setting legal precedents and fostering a culture of human rights and environmental protection.

The rise and evolution of Public Interest Litigation in India have been transformative, making it a potent instrument for promoting justice and public welfare. PIL has democratized access to justice, providing a voice to the voiceless and holding institutions accountable. It represents a shining example of how the Indian judiciary has adapted to the changing needs of society, ensuring that the principles of democracy, justice, and the rule of law remain at the forefront of the nation's legal framework.

On Which Matters PILs Can Be Filed?

PILs in India can address a wide array of issues, including but not limited to:

  1. Human Rights Violations: Cases involving violations of fundamental rights and freedoms, such as custodial torture, extrajudicial killings, and discrimination.
  2. Environmental Concerns: Cases related to the preservation of natural resources, pollution control, conservation of wildlife, and prevention of deforestation.
  3. Public Health: Matters pertaining to healthcare, access to clean drinking water, and the spread of diseases.
  4. Corruption: Cases that expose corruption and maladministration at all levels of government.
  5. Women's Rights: Issues concerning women's safety, gender equality, and protection from domestic violence.
  6. Education: Ensuring quality education and accessibility for all, particularly in rural areas.

Who Can File PIL and How?

Who Can File PIL?

  1. Any Citizen: One of the defining features of PIL is that any Indian citizen can file a PIL petition. There is no requirement for the petitioner to have a personal or direct interest in the case. This inclusivity allows concerned individuals to act on behalf of the public interest, making it accessible to a wide range of people.
  2. Non-Governmental Organizations (NGOs): NGOs and civil society organizations are also eligible to file PILs in the Indian courts. Many NGOs have been at the forefront of advocating for public interest causes, and they play a crucial role in representing marginalized or disadvantaged groups.
  3. Elected Representatives: Members of Parliament (MPs) and Members of Legislative Assemblies (MLAs) can file PILs on issues that fall within their jurisdiction. These elected officials can use PIL as a means to address the concerns of their constituents and hold the government accountable.

The Locus Standi Rule:

One of the distinctive features of PIL is the relaxation of the traditional "Locus Standi" or standing requirement, which typically necessitates that a petitioner must have a direct and personal interest in the matter at hand. In PIL, the courts have recognized that violations of public rights and interests affect society as a whole, and therefore, any concerned citizen can initiate legal action without a direct personal stake in the case. This has significantly broadened the accessibility of the Indian justice system.

How to File PIL?

  1. Writ Petition: Most PILs are filed as writ petitions under Article 32 of the Indian Constitution in the Supreme Court or Article 226 in the respective High Courts. The petitioner can approach the court directly by filing a writ petition outlining the issue of public interest. This petition typically includes details of the case, the legal provisions violated, and the relief sought.
  2. Letter Petition: In certain cases, a letter addressed to the Chief Justice of India or the Chief Justice of the concerned High Court can serve as the basis for filing a PIL. If the letter outlines a matter of public interest, the court may treat it as a PIL and take Suo Moto cognizance of the issue.
  3. Pro Bono Legal Aid: In many cases, individuals or organizations with limited resources receive pro bono legal assistance from lawyers who are willing to take up public interest cases. Legal aid clinics, legal NGOs, and advocacy groups often provide such support.
  4. Online Petitions: With the advancement of technology, online platforms have become a medium for initiating PILs. Online petitions and campaigns can gather public support and be presented as evidence of public interest when filing a PIL in court.
  5. Through Interventions: In some instances, individuals or organizations can file PILs by intervening in existing cases. If an ongoing case pertains to a matter of public interest, other parties may seek to intervene and represent the broader public perspective.
  6. Public Interest Law Firms: Some law firms and lawyers specialize in public interest litigation and may offer their services to those seeking to file PILs. They have the expertise to guide petitioners through the legal process.

It's important to note that while PIL allows for a more flexible approach to filing cases, the Indian judiciary is vigilant in scrutinizing petitions to ensure they genuinely serve the public interest. The courts have laid down guidelines to discourage frivolous or malicious petitions and protect the integrity of the PIL mechanism. When filing a PIL, it is essential for the petitioner to provide accurate information, adhere to the prescribed legal procedures, and ensure that the case genuinely represents a matter of public concern.

Against Whom PIL Can Be Filed?

PILs can be filed against any individual, organization, or government entity that violates fundamental rights or contributes to a matter of public concern. This includes government agencies, public servants, corporations, and individuals who act against the public interest.

Importance of PIL in India

The importance of PIL in India cannot be overstated. It has democratized access to justice and has been instrumental in:

  1. Safeguarding Fundamental Rights: PIL has been used to protect and uphold the fundamental rights of citizens, making the government more accountable.
  2. Environmental Conservation: PIL has played a crucial role in preserving natural resources and promoting sustainable development.
  3. Promoting Transparency: It has exposed corruption and inefficiency in government institutions, fostering transparency and accountability.
  4. Advocating for the Marginalized: PILs have been a voice for the marginalized, advocating for the rights of women, children, and the economically disadvantaged.


Despite its numerous advantages, PIL is not without its criticisms:

  1. Judicial Activism: Some critics argue that the judiciary's expanded role through PIL may encroach on the executive and legislative branches of government, leading to "judicial activism."
  2. Delays in Justice: The backlog of cases in Indian courts has led to significant delays in delivering justice, affecting the effectiveness of PIL.
  3. Frivolous Petitions: There have been instances of misuse or abuse of PIL by individuals or organizations with vested interests, filing frivolous petitions that burden the courts.

Abuse of PILs

The abuse of PILs is a genuine concern. Some individuals or groups have exploited this mechanism for personal gain, settling personal scores, or advancing political agendas. To address this issue, the judiciary has started imposing penalties on those who file malicious or frivolous petitions. The courts have also become more selective in the cases they entertain, focusing on those that genuinely serve the public interest.

Landmark Cases in India

Several landmark PIL cases have significantly impacted Indian society:

  1. Vishaka v. State of Rajasthan (1997)[3]: This case led to the formulation of guidelines to combat sexual harassment in the workplace, setting the stage for women's rights and gender justice in India.
  2. MC Mehta v. Union of India (1986)[4]: MC Mehta, a prominent environmental activist, filed PILs that led to the closure of hazardous industries in Delhi and the establishment of the Supreme Court-mandated Environmental Pollution (Prevention and Control) Authority.
  3. Bandhua Mukti Morcha v. Union of India (1984)[5]: This PIL led to the release of bonded laborers, highlighting the issue of modern slavery and exploitation in India.
  4. Olga Tellis v. Bombay Municipal Corporation (1985)[6]: This case highlighted the rights of the homeless and slum dwellers, ensuring that they could not be evicted without due process and providing legal protections.
  5. Maneka Gandhi v. Union of India (1978)[7]: This case expanded the scope of personal liberty by emphasizing that the right to travel abroad is a fundamental right. It laid down the principle that any law depriving a person of personal liberty must be fair, just, and reasonable.
  6. Rajasthan State Electricity Board v. Mohan Lal (1967)[8]: This early PIL case established that a High Court could intervene in Labor-related issues. It led to the court ordering the reinstatement of terminated workers.
  7. S.P. Gupta v. Union of India (1981)[9]: This case, also known as the "First Judges Case," addressed judicial appointments and the independence of the judiciary. It contributed to the development of guidelines for appointing judges.
  8. Common Cause v. Union of India (2018)[10]: In this case, the Supreme Court ruled that passive euthanasia (withholding or withdrawing medical treatment to a terminally ill patient) is legal under specific circumstances. It was a significant step in recognizing the right to die with dignity.
  9. MC Mehta v. Kamal Nath (1997)[11]: This PIL case addressed vehicular pollution in Delhi and led to the conversion of public transport vehicles to run on Compressed Natural Gas (CNG), significantly improving air quality.
  10. Vineet Narain v. Union of India (1997)[12]: This case exposed the Hawala scandal and corruption in high places, leading to investigations and prosecutions of several politicians and officials.
  11. State of Uttaranchal v. Balwant Singh Chaufal (2010)[13]: The Supreme Court reiterated the details of the origin and development of PIL and laid down important guidelines for checking its misuse.

These landmark PIL cases have significantly influenced Indian jurisprudence, addressing a wide range of issues from environmental protection and human rights to governance and legal principles, thereby contributing to the growth of public interest litigation in India.

Global jurisprudence on PIL

Comparing Public Interest Litigation (PIL) in India with social interest litigation in other foreign jurisdictions provides valuable insights into the global context of public interest litigation. While India's PIL system is unique in many aspects, it has been influenced by jurisprudence from other countries. Moreover, India's innovative approach to PIL has served as an inspiration for similar systems in other nations.

Comparisons with Foreign Jurisdictions:

  1. United States - Class Action Lawsuits: India's PIL system bears some resemblance to class action lawsuits in the United States. In both, individuals or entities can bring legal action on behalf of a group or the public at large. However, the primary distinction is that class action suits in the U.S. are generally initiated by affected parties seeking redress, whereas PIL in India can be initiated by anyone acting in the public interest, even without personal involvement.
  2. South Africa - Public Interest Litigation: South Africa has a well-established tradition of public interest litigation that aligns closely with India's PIL system. South African courts have taken inspiration from Indian PIL cases to uphold social justice and human rights.
  3. Nigeria - Public Interest Litigation: Nigeria's judicial system has embraced public interest litigation to address various social and environmental concerns. Nigerian courts have taken cues from Indian PIL cases, particularly in matters related to environmental protection and human rights.

Indian Influence on Global Jurisprudence:

India's PIL system, with its innovative approach, has left an indelible mark on the global landscape of public interest litigation. Some countries have adopted similar systems inspired by India's experience:

  1. Bangladesh: The concept of public interest litigation was embraced in Bangladesh, following India's example. Bangladesh's judiciary has been proactive in addressing public interest concerns, including environmental issues and human rights.
  2. Nepal: Nepal's judiciary has taken inspiration from India's PIL jurisprudence to address public interest matters, such as environmental conservation and human rights.
  3. Pakistan - Pakistan has also embraced the concept of public interest litigation. Pakistan's judiciary has drawn inspiration from India's PIL jurisprudence in addressing human rights violations and public welfare issues.
  4. Sri Lanka: Sri Lanka has also adopted public interest litigation, drawing from India's experiences in addressing issues related to environmental conservation and social justice.
  5. United Kingdom: While the United Kingdom has not implemented a system exactly mirroring India's PIL, the concept of strategic litigation for public interest causes has gained prominence. Various organizations and legal groups in the UK take on cases with far-reaching public implications, similar to the spirit of PIL.
  6. Australia: Public interest litigation is becoming increasingly common in Australia, where individuals and organizations are taking legal action to protect the environment, indigenous rights, and other social causes.

Inspiration from Existing Jurisprudence:

The Indian Supreme Court has indeed taken inspiration from legal developments in other countries while shaping the PIL framework. Key aspects of PIL, such as the relaxation of the Locus Standi rule and the emphasis on protecting fundamental rights, have been influenced by international jurisprudence and global human rights standards. The Indian judiciary has remained open to global legal developments and incorporated them into its jurisprudence when relevant to advancing the cause of public interest and social justice. India's PIL system is a remarkable example of how innovative approaches to legal remedies can be influential beyond national borders. It has served as a source of inspiration for similar systems in other countries, reinforcing the notion that the law can be a powerful tool for protecting the rights and interests of the public on a global scale[14].


In the ever-evolving tapestry of Indian jurisprudence, Public Interest Litigation (PIL) has emerged as a dynamic and transformative force. Its genesis, growth, and numerous landmark cases illustrate its pivotal role in ensuring the protection of the rights and interests of the Indian public. By allowing any concerned citizen or group to be the voice of the marginalized or the protector of fundamental rights, the judiciary has blurred the line between justice and society.[15] PIL has not only acted as a bridge but as a beacon of hope, shining light on the path to justice for countless individuals and groups across the nation. The judiciary's proactive role in addressing issues of public interest, and sometimes even preempting crises, has showcased the instrumental role of PIL in driving social change. The judiciary has also issued guidelines, taken steps to curb frivolous petitions, and penalized those who misuse this powerful tool.[16] This demonstrates the judiciary's commitment to preserving the integrity of PILs and ensuring they remain an instrument for social justice rather than personal gain.

In conclusion, PIL in India stands as a vibrant and dynamic facet of the nation's legal system. It is an embodiment of the principle that justice must not only be done but must also be seen to be done. It is a testament to the resilience and adaptability of Indian democracy and the unwavering commitment of the judiciary to safeguard the rights and interests of the public. As India continues to grow and evolve, PIL will undoubtedly remain a critical pillar in the quest for justice, accountability, and social transformation.
