Locus standi is the legal right of a person to bring a case before a court, determined by whether the person has a sufficient stake or interest in the outcome of the dispute. Under Indian law, locus standi was traditionally restricted to persons directly affected by the impugned action, but has been significantly liberalised through the development of Public Interest Litigation (PIL) jurisprudence by the Supreme Court, particularly under Articles 32 and 226 of the Constitution.
Legal definition
Indian law does not have a single statutory definition of locus standi. The concept is operationalised through the constitutional provisions governing access to courts:
Article 32(1): The right to move the Supreme Court by appropriate proceedings for the enforcement of the rights conferred by this Part is guaranteed.
Article 226(1): Notwithstanding anything in article 32, every High Court shall have power, throughout the territories in relation to which it exercises jurisdiction, to issue to any person or authority, including in appropriate cases, any Government, within those territories directions, orders or writs, including writs in the nature of habeas corpus, mandamus, prohibition, quo warranto and certiorari, or any of them, for the enforcement of any of the rights conferred by Part III and for any other purpose.
In traditional civil litigation, locus standi requires the plaintiff to demonstrate a direct and personal interest in the subject matter of the dispute. In constitutional litigation, the Supreme Court has relaxed this requirement to allow public-spirited individuals to approach the court on behalf of persons unable to do so themselves.
How courts have interpreted this term
S.P. Gupta v. Union of India [Supreme Court of India, seven-judge Bench, decided 28 December 1981, 1981 INSC 209]
In the Judges Transfer case, which arose from writ petitions by lawyers challenging the independence of the judiciary, Bhagwati J. held that where a legal wrong or injury is caused to a person or determinate class of persons by violation of a constitutional or legal provision, and that person or class by reason of poverty, helplessness or disability or socially or economically disadvantaged position is unable to approach the court for relief, any member of the public can maintain an application for an appropriate direction, order or writ in the High Court under Article 226 and, where a fundamental right is breached, in the Supreme Court under Article 32. He further held that any member of the public having sufficient interest can maintain an action for judicial redress for public injury arising from breach of public duty or from violation of a provision of the Constitution or the law, and seek enforcement of that duty and provision. The judgment states that it is not possible to lay down any hard and fast rule for defining "sufficient interest".
Why this matters
Locus standi determines the gatekeeping function of courts — who can enter the judicial system and who cannot. The relaxation of standing through public interest litigation has widened access to the Supreme Court and High Courts for matters of public concern.
For practitioners, the dual framework of standing in Indian law requires careful assessment. In ordinary civil suits, the plaintiff must demonstrate a direct personal interest — a stranger to a contract cannot sue for its enforcement, and a person not affected by a government order cannot challenge it. However, in constitutional matters involving fundamental rights, the standing threshold is significantly lower, requiring only that the petitioner act in good faith and in the public interest.
A common misunderstanding is that PIL permits anyone to file any case. In S.P. Gupta the standing recognised is that of a member of the public having "sufficient interest" in redressing a public injury or enforcing a public duty, and the Court declined to lay down a rigid definition of that interest.

Frequently asked questions
Who has locus standi to file a PIL in India?
In S.P. Gupta v. Union of India (1981 INSC 209), the Supreme Court held that where a legal wrong or injury is caused to a person or determinate class of persons who, by reason of poverty, helplessness, disability or a socially or economically disadvantaged position, cannot approach the court, any member of the public can maintain an application under Article 226 in the High Court or, for a breach of fundamental rights, under Article 32 in the Supreme Court. It also held that any member of the public having sufficient interest can maintain an action for redress of a public injury arising from breach of a public duty or violation of a constitutional or legal provision.
Can a person without locus standi be added as a party to a suit?
Under Order I Rule 10(2) of the Code of Civil Procedure, 1908, the Court may at any stage, on or without the application of either party and on just terms, order that the name of any party improperly joined be struck out, and that the name of any person who ought to have been joined, or whose presence before the Court may be necessary to enable it effectually and completely to adjudicate upon and settle all the questions involved in the suit, be added, whether as plaintiff or defendant.
Does locus standi apply in criminal cases?
The procedural statute under which a criminal proceeding is brought determines who can set it in motion. Public interest petitions under Articles 32 and 226, as in S.P. Gupta, are a separate, writ-based route to the High Courts and the Supreme Court.
