A PIL is filed for the enforcement of public interest or general interest, not for a private interest.

Any citizen of India, any non-profit organization, or any government agency can file a PIL.

A PIL is filed to enforce public interest, protect the rights of the general public, and challenge the actions of the government.

The procedure for filing a PIL involves filing a petition in the Supreme Court or High Court, serving a notice to the respondent, and waiting for the court's decision.

The role of the court in a PIL is to hear the arguments of the petitioner and the respondent, decide whether the PIL is maintainable, and grant relief to the petitioner if the PIL is maintainable.

Olga Tellis vs Bombay Municipal Corporation, MC Mehta vs Union of India, and Vishaka vs State of Rajasthan are some of the landmark PIL cases in India.

Lack of awareness about PIL, financial constraints, and legal complexities are some of the challenges faced in filing a PIL.

Public awareness campaigns, legal aid clinics, and judicial reforms are some of the ways to overcome the challenges faced in filing a PIL.

PIL provides access to justice for the marginalized, promotes transparency and accountability in governance, and helps in the enforcement of fundamental rights.

The scope of PIL has expanded, the standing requirements have become more flexible, and the courts have become more proactive in hearing PILs.

Increasing use of PILs to challenge environmental issues, protect the rights of women and children, and challenge the actions of private corporations are some of the recent trends in PIL litigation in India.

PIL litigation in India has been criticized for being used for political purposes, harassing individuals and organizations, and leading to judicial overreach.

Imposing stricter standing requirements is one of the proposed reforms to PIL litigation in India.

PIL litigation in India is likely to continue to play an important role in protecting public interest, become more streamlined and efficient, and be used more strategically to address pressing social issues.
